  • 9. ForewordYossef S.Ben-PorathKent State UniversityIn the preface to thisedition ofhis MMPI-A interpretive guide, RobertArcherobservesthat the empirical literature available to guide the tests interpretation has expandedconsiderably since the second editionspublication in 1997. Asthe individualwho hasplayed the leading role in generating this research and who has been recognized asthe authority on adolescent applications of the MMPIsince the publication of his firstbook on the topic in 1987, Dr. Archer is uniquely qualified to provide this updatedtext on the MMPI-A.This edition retains all ofthe strengths ofits predecessors. In the first chapter,useofthe MMPI-Ais placed in the broader context of current understanding of adolescentdevelopment in general and psychopathology in particular. This chapter providesvital background for interpreting the MMPI-Ain adolescent assessment, and Iwouldadmonish readers not to give in to the temptation to skip it and head straight for thebooks "interpretive meat." The second chapter, on the development ofthe MMPIandMMPI-A, similarly provides important background information that should not beoverlooked.The adolescent MMPIliterature, although substantially expanded, remains man-ageable enough in size to allow Dr.Archerto follow in the tradition ofDahlstrom andWelshsoriginalMMPI Handbook by combiningin one volumea scholarlyreviewof thetests empirical literature and a practical guide to its interpretation. Thebooks users,especially students gaining their first introduction to the test, would do well to firstread the entire text ofeach chapter beforeusing the "Interpretation Guidelines" tablesfor the scales in routine MMPI-Ainterpretation. These tables provide a scale-by-scaleuser-friendly summary of Dr. Archers review of the extensive empirical literature,supplemented by his broad clinicalexperiencewith the test. They remain the heartofthis text, and many users will refer to them routinely in day-to-day practice.Since the 1997 edition, several new scales and a critical item set have been intro-duced for the MMPI-A, and this edition provides much-needed guidance on theirincorporation into MMPI-A interpretation. The most important innovation of thisedition is the inclusion of a new, comprehensive chapter on forensic applicationsofthe MMPI-A. This chapter will be of greatest interest to the increasing number ofpsychologists who use the test in forensic evaluations; however, it should be studiedby all of the tests users. As the mental health field becomes increasingly litigious andpsychologists play an expanding role in the forensic evaluation of adults and adoles-cents, anyone using the MMPI-A,even primarily for clinical assessments, would bewell advised to become familiar with the background for and literature on forensicapplications of the test. Chapter 7 provides this much-needed information.ix
  • 10. x FOREWORDThe appendixes also continue in the tradition of the MMPI Handbook by providinga complete set of tables needed for scoring the MMPI-A. They incorporate in onevolume scoring keys and (where appropriate) T-score lookup tables for all currentlyused and researched MMPI-A scales, including many that are not available in thetests manual, published in 1992. The eight appendixes therefore constitute the mostcurrent, comprehensive resource available for scoring the MMPI-A.Its fair to say that this, the third edition of MMPI-A: Assessing Adolescent Psy-chopathology, is the most up-to-date, and authoritative MMPI-A interpretive guide.The text places at users fingertips all the information needed to administer, score,and interpret the MMPI-Abased on current knowledge about the test and experiencewith its use. Students of the MMPI-Awill find in it a rich,integrativereview of the in-struments history and empirical literature.Users of the test will find an unparalleledcomprehensive yet highly practical guide for MMPI-A interpretation.
  • 11. Preface to the Third EditionThe first edition of MMPI-A-Assessing Adolescent Psychopathology was published inAugust 1992 to coincide with the original release of the MMPI-A manual testingmaterials. Thesecond edition was published in 1997and incorporated nearly 100 newreferences, but most of these citations were related to MMPI-2studies, and relativelylimited workhad beendoneontheMMPI-A tothat point.Thisthird edition, publishednearly 12 yearsafter the releaseofthe MMPI-A, reflects the extensivebody of literaturethat has now developed on the MMPI-A.It incorporates165new references, mostofthesebased directlyon research investigationswiththe MMPI-A.Italsodiscusses newfeatures of the MMPI-A that havebeen developed sincethe second edition, includingthe MMPI-A Psychopathology-Five (PSY-5) scales, the MMPI-A ContentComponentscales, and the critical item set developed by Forbey and Ben-Porath. In addition, thisedition contains a new chapter that covers forensic applications of the MMPI-A inrecognition of the rapid and dramatic expansion of the field of forensic psychologyin the last few years.In summary, the purpose of the current revision is to update the information pro-vided and take into account the rapid expansion of the MMPI-Aliterature. Its basicstructure, however, is essentially the same as that of its predecessors. For example,it continues to include a chapter on the critical issue of adolescent development andpsychopathology as well as a comprehensivereview ofthe development, administra-tion, and scoringproceduresof the MMPI-A. Likewise,separate chaptersare devotedto the interpretationof validity scales,clinicalscales, and contentand supplementaryscales, and a final chapter addresses the challengingtask ofintegratingMMPI-A datainto an overall interpretivereport. As previously noted, an additional chapter givesan overview of the application of the MMPI-A in providing information to judgesand juries involved in determining civil and criminal issues. It is my hope that thisrevised text keeps the best features of the earlier editions while expandingcoverageto include the newest literature on this test instrument.My intention was to producea text that provides useful and practical information to the clinician in utilizing theMMPI-A in clinicalassessments while alsoproviding sufficiently detailed informationto stimulate future research efforts with this instrument.In addition to the individuals mentioned in the prefacesto my original and secondeditions, I would also like to give recognition to several individuals who played aninvaluable role in the creation of this third edition. David Elkins, Research Associateat the Eastern Virginia Medical School, has been a central resource and colleague inthe development of this text and in all of our research efforts since 1992. Additionally,I wish to express my sincerest appreciation to Denise Holloway, who has handled thexi
  • 12. xii PREFACE TO THE THIRD EDITIONdemands of the second and third edition ofthis textwith much grace and competencewhile also recently completing her 10-year tenure as the EditorialAssistantfor thejour-nal Assessment. Iwould also like to express my thanks to BeverlyKaemmerof theUni-versity of Minnesota Press for all of her help and assistance in providing me with thematerials necessary for this revision. It has been my privilege to work with a numberof outstanding psychologists in pursuing my interest in the MMPI-A. Dr. Rebecca V.Stredny, EVMSpost-doctoral fellowin forensic psychology,has been verykind in help-ing review and prepare the materials for this text. Dr. Richard Handel is a colleagueand member of our faculty at the Eastern Virginia Medical School, and his energy,creativity, and enthusiasm for the MMPI-2 and MMPI-A have contributed to a veryenjoyable and productive collaborative process. Dr. Yossef Ben-Porath of Kent StateUniversity has facilitated and collaborated on many of our research studies, and hissupport is deeply appreciated. Drs. Roger Greene, David Nichols, and IrvingGottes-man have been friends and colleagues for many years and have been invaluable intheir willingness to share their time, resources, and data sets to explore manyMMPI-Aand MMPI-2 issues. Further, the funding support from the University ofMinnesotaPress and from the Norfolk Foundation has played a crucial role in providing theresources necessary to conduct systematic investigations of the MMPI-A. Finally, Iwould like to express my deepest gratitude for the longstanding patience ofmy wife,Dr. Linda R.Archer, and my daughter, Elizabeth M. Archer, and for their critical sup-port on all of my MMPI, MMPI-2, and MMPI-A projects. While the MMPI-A maynever "love me back," I am very grateful that this is most assuredly not true of mywife and daughter.I conclude this preface with the observation that the MMPI and MMPI-A haveserved as a splendid focus for my research career. When I began investigations inthe mid-1970s on the use of the MMPI with adolescents, my initial research questioninvolved the effects of using various normative sets with adolescents (e.g.,adolescentversus adult norms) and the implications ofthese choices on profilecharacteristics andinterpretation. Now, nearly 30years later, I continue to pursue issues that directlyfol-low from those original questions;for example, how effective are the MMPI-Aadoles-cent norms in distinguishing between adolescents in various clinical and nonclinicalsettings, and what factors contribute to the relatively low mean T-score values oftenfound among adolescents in clinicalsettings? Ithas been arare privilege tobe engagedwith a psychological assessment instrument that exhibits the complexity,popularity,and clinical utility of the MMPI-A.It is my hope that this third edition will reflect mypassion for this instrument as well as provide the necessary informationto stimulateother clinicians and researchers in the pursuit of similar careers.

  • 15. 1Adolescent Developmentand PsychopathologyMuch ofthe confusion and controversy traditionallysurrounding the use ofthe MMPIwith adolescent respondents has resulted from the application of this instrumentwithout an adequate understanding ofthe unique characteristics of adolescent devel-opment. Unfortunately, many clinicians and researchers have attempted to interpretadolescents MMPI profiles using procedures that have been established for the as-sessment ofadults. There are areas ofinterpretation in which the approach developedfor adults will work effectively in the understanding of adolescents responses. Thereare also numerous areas, however, in which the use ofpractices or procedures derivedfor adults will result in substantialinterpretiveerrorswhen applied to adolescents.Al-though developmentofthe MinnesotaMultiphasicPersonality Inventory-Adolescent(MMPI-A) has substantially assisted in deriving interpretive comments of direct rel-evance to adolescents, using this specialized form of the MMPI does not substitutefor an awareness of salient developmental issues. Thus, the purpose of this chapteris to provide a brief overview of adolescent development and psychopathology,withparticular attention focused on ways in which developmentally related issues mayaffect MMPI/MMPI-Ainterpretation practices.DEVELOPMENTAL TASKS DURING ADOLESCENCEAchenbach (1978) suggested that an understanding of psychopathology in childrenand adolescents mustbefirmly grounded inthe study ofnormaldevelopment. Humandevelopment is a continuous process, but there may be criticalperiods in our devel-opment during which adaptationalsuccess or failure heavily influences the courseoflater development in the life cycle. Adolescence clearly is one of these critical devel-opmental transitions. Holmbeck and Updegrove (1995) observed that adolescence is"characterized by more biological, psychological, and social role changes than otherlife stages except infancy" (p. 16). As noted by Petersen and Hamburg (1986), thenumber and extent of changes that occur simultaneously during adolescencepresentmajor challenges to the development of mature and effective coping strategies. In-effective coping strategies may contribute to a variety of problem behaviors duringadolescent development. Further, failures in adolescent development may result inthe manifestation of psychopathology during later life stages.1
  • 16. 2 CHAPTER 1Three major areas of changes and challenges that face the individual during ado-lescence are here reviewed: physiological processes, cognitive processes, and psycho-logical and emotional challenges.Physiological/Sexual MaturationKimmel and Weiner (1985) defined puberty as "the process of becoming physicallyand sexually mature and developing the adult characteristics of ones sex" (p. 592).Petersen (1985) noted several characteristics of puberty that are important in un-derstanding adolescent development. Puberty is a universal experience that may,however, be delayed, or in some cases even prevented, by the occurrence of physicaldisease or traumatic psychological events. Paikoff and Brooks-Gunn (1991)noted thatthe timing of puberty has been shown to vary as a function of the adolescents healthstatus, nutrition, ethnicity,genetic inheritance, exercise level, and stress experiences.They observed that the parent-child relationship is typically affected by pubertal de-velopment, with decreases in time spent with parents and submissiveness toparentaldecisions typicallyfound during early adolescence.Further,Petersen stressed that pu-berty isaprocess rather thanan isolated temporalevent.Thisprocess involvesphysicalchanges that result in a sexuallyimmature child achievingfull reproductivepotential.These changes are typically manifested in the growth of underarm and pubic hair,maturation of genitalia, and the first menstruation in girls. Often, the clearest signsofadolescent development are physical changes associated with the onset of puberty.Fundamental physical changes, including changes in endocrinological,biochemi-cal, and physiological processes, occur during adolescence. For example, Stone andChurch (1957)noted that an individualis expected to increase25%in height and100%in weight during this developmental stage. Additionally,there is a marked increase inpituitary activity leading toincreased production ofhormones by the thyroid, adrenal,and other glands centrally involved in sexual maturation.There are notable differences in the rate of physical maturation between boys andgirls, and there are also very wide individual variations in sexual maturation withingenders. Figures 1.1and 1.2show varying degrees of sexual maturation for 141-year-old boys and 12 -year-old girls and the velocity of growth in height by year of life.The data in Fig. 1.1 for pubertal development illustrates both the earlier maturationoffemales in relation to males and the wide differences in pubertal development withingenders at identical chronological ages. To the extent that pubertal development isprecocious or significantly delayed, stress may occur that can be reflected in lowerself-esteem or self-conceptfor the adolescent during this period. A recentmonographby the American Psychological Association (APA, 2002) provided data indicating thatcurrently pubertal development among American adolescents is occurring substan-tially earlier than the guideposts originally provided by Tanner in the late 1960s forhis British sample of adolescents. For example, the average age of menarchefor girlsin the United States is now around 12.5, and for boys the onset of puberty (as markedby the enlargement of the testes) occurs at around age 11.5, with the first ejaculationtypically occurring between the ages of 12 and 14. A recent survey of 17,000 healthygirls between the ages of3 and 12who were participating in office visits with their pe-diatricians found that 6.7%of white girls and 27.2% ofAfrican Americangirls showedsome signs of puberty as early as age 7, including pubic hair or breast development(Herman-Gliddens et al., 1997; Kaplowitz & Oberfield, 1999). A recent descriptionofthe adolescent growth spurt by Hofmann and Greydanus(1997) isgenerally consistentwith the earlier data by Tanner in indicatingthat the rapid skeletal development that

Copy-right © by W.B.Saunders Company.Reprinted by permission.)marks the growth spurt usually begins at around ages 10 to 12 in girls and around ages12 to 14 in boys. The most dramatic rate of physical growth tends to occur betweenthe ages of 12 and 15, with the peak of the growth curve occurring approximately 2years earlier for females than for males (Fig.1.2).An illustration of the influence of developmental forces on MMPI responses isprovided by the abbreviated item "worried about sex." This item serves as a memberof scales3,5,and 8.The Minnesota Multiphasic Personality Inventory-2 (MMPI-2) Manual
  • 18. CHAPTER 1FIG. 1.2. Velocity of growth in height at various ages. (From Tanner, Whitehouse, andTakaishi, 1966. Copyright © by the Archives of Disease in Childhood.Reprintedby per-mission.)(Butcher, Dahlstrom, Graham, Tellegen, &Kaemmer, 1989) indicates that this item isendorsed in the true direction by 13% of adult female respondents in the MMPI-2normative sample and 15%of adult men. In contrast to adult samples, however,thisitem was endorsed as true by 37.2% of adolescent females and 30.2%ofadolescentmales in the MMPI-A normative sample (Butcher et al., 1992). The higher rate ofendorsement of this item in the critical direction by the 14- to 18-year-old teenagersprobably reflects the high level of stress for adolescents related to issues of sexualmaturation as well as sexual identity.CognitiveMaturationAdolescence may also be defined in terms ofchanges that occurin cognitive processes.The work of Piaget and his colleagues offers an approach to understanding thesecognitive changes, with the final stage of cognitive development in Piagets (1975)paradigm unfolding during adolescence. Specifically,Piaget postulated that, during4
  • 19. ADOLESCENT DEVELOPMENTAND PSYCHOPATHOLOGY 5early adolescence, the individual typically makes the transition from the ConcreteOperations stagetothe FormalOperation stage,the latter characterizedby thecapacityto manipulate ideas and concepts. According to Piaget (1975), "The adolescent is anindividual who is capable... ofbuilding and understanding ideas or abstracttheoriesand concepts. The child does not build theories" (p. 105). Thus, the adolescent is ableto discern the real from the ideal and to become passionately engaged by abstractconcepts and notions. Adolescents begin to think of their world in new ways and todevelop the ability to "think about thinking." Related to these changes in cognitiveskills, Elkind (1978, 1980) argued that, as adolescents become capable of thinkingabout their thoughts, they may also become excessively concerned with how theyare perceived by others. This preoccupation includes an exaggerated view of theuniqueness of their own experiences and the amount of time devoted by others totheir appraisal. Elkind labeled the egocentric tendency of adolescents to believe thattheir behavior is intensely scrutinized by others as "the imaginary audience" (Elkind& Bowen, 1979).Part of this self-absorption and belief in the uniqueness of ones own experiencesmay be reflected in the endorsement rate differences between adults and adolescentsfor the following abbreviated item, which is a member of scales Pt and Sc:"Strange thoughts."(Endorsed true by 15%of MMPI-2 adult males and 10%of adult females vs.45%of boys in the MMPI-A normative sample and 46% of MMPI-Ateenage girls.)and to the followingabbreviated item, a member of scales Pd, Pa,and Sc:"Misunderstood."(Endorsed true by 9% of adult men and 9% of adult women in the MMPI-2normative sample vs. 25.6%of adolescent boys and 37.4%of adolescent girls inthe MMPI-Anormative sample.)and to the following abbreviated item, a member of the Mf and Si scales:"Unbothered by not being better looking."(Endorsed true by 77% and 59% of the MMPI-2 male and female normativesamples, respectively, vs. 49%of adolescent boys and 38%of adolescent girls inthe MMPI-Anormative sample.)Psychological DevelopmentFinally, a host of psychological and emotional tasks, including the processes of in-dividuation, the formation of ego identity, and ego maturation, are accomplishedduring adolescence. Blos (1967) discussed individuation as a process involved withthe development of relative independence from family relationships, the weakeningof infantile object ties, and an increased capacity to assume a functional role as amember of adult society. Blos defined and described this task as similar to the moreprimitive struggle for individuation in the attainment of object constancy that occurstoward the end of the third year of life. Thus, early adolescents have marked ambiva-lence concerning issues of independence versus dependence, particularly in termsoftheir relationships to their parents. This ambivalence is likely to be seen in rapid andmarked attitudinal and behavioral changes (e.g.,one moment protesting any parental
  • 20. 6 CHAPTER 1involvement or supervision and the next moment regressing to marked dependencyon mother or father).Erikson (1956) described ego identity formation during adolescence as the assem-bly of converging identity elements that occur at the end of childhood—an assemblyachieved through a process of normative crises. Ego identity was viewed by Erikson asincluding the conscious sense of individual identity as well as an unconscious striv-ing for a continuity of personal character. In the process of ego formation, the egointegrates previous childhood identifications into a new totality, which lays the foun-dation of the adult personality. Positive resolution of this issue leads to a sense ofegoidentity, or continuity in ones self-definition. Negative resolution could result inegodiffusion, or uncertainty about who one is and what one will become in the future. Thefailure to achieve ego identity is related to the diagnostic category of identity prob-lem (313.82) as described in the American Psychiatric Associations (1994) Diagnosticand Statistical Manual of Mental Disorders (DSM-IV). Marcia (1966) further definedEriksons concept of ego identity in terms of two variables: commitment (whether ornot the individual has accepted a set of values) and crisis (whether or not the indi-vidual has experienced an inner struggle in arriving at personal acceptanceof a setofvalues). These two variables combine to yield four identity statuses in Marcias model:diffusion (no commitment, no crisis),foreclosure (commitment without crisis), morato-rium (crisis without commitment),and achievement (commitmentafter crisis).Marciaargued that these categories, in the order given, represent developmental levels ofincreasingly advanced maturation.The process of individuation is most clearly noted during early phases of ado-lescence, whereas the process of identity formation and consolidation is typicallymanifested during later stages of adolescence. As a result of these processes, ado-lescents will typically modify the way in which they interact with and relate toothers. Specifically, adolescents begin to increase their involvement with peers andto decrease their immediate identification with family members. Further, the earlystages of individuation may result in an increase in conflict with parents, as the ado-lescents attempt preliminary definitions of the self based on identifying the waysin which their feelings, thoughts, and attitudes may differ from those of their par-ents.Loevinger (1976)articulated a concept ofego development in reference to the frame-works of meaning that individuals impose on their life experiences. In Loevingersmodel, the concept of ego development is a dimension of individual differences aswell as a developmental sequence of increasingly complex functioning in terms ofimpulse control, character development, interpersonal relationships, and cognitivecomplexity. At the three lowest levels of ego development, collectively grouped intothe preconformist stage, the individual may be described as impulsive, motivated bypersonal gain and the avoidance of punishment, and oriented to the present ratherthan the past or future. Cognitive styles are stereotyped and concrete, and interper-sonal relationships are opportunistic, exploitive, and demanding. During the secondbroad stage of development, referred to as the conformist stage, the individual beginsto identify his or her welfare with that of the social group. The individual places em-phasis on conformity with socially approved norms and standards and on issues ofsocial acceptability in terms of attitudes and behaviors. As the individual enters thepostconformist stages of development, self-awareness, cognitive complexity, and in-terpersonal style become increasingly complex, and a balance is achieved betweenautonomy and interdependence. The maturational stages described by Loevinger donot refer to specific age groups, but she noted that the higher stages ofegodevelopment
  • 21. ADOLESCENT DEVELOPMENTAND PSYCHOPATHOLOGY 7would rarely be achieved by adolescents. Loevingers view of development is verycomprehensive and served as a basis for the development of the MMPI-AImmaturity(MM) scale,which is described in chapter6.The following five MMPI abbreviated items illustrate substantial differences inendorsement frequency between adults in the MMPI-2 normative sample and ado-lescents in the MMPI-Anormative sample:"Rarely quarrel with family."(Endorsed true by 78% of adult women and 79% of adult men vs. 38% of ado-lescent girls and 46% of adolescentmales.)"Habits of some family members very irritating."(Endorsed true by 66% of adult women and 48% of adult men vs. 79% of ado-lescent girls and 67%of adolescent boys.)"Most of family sympathetic."(Endorsed true by 53% of adult women and 56% of adult men vs. 31% of ado-lescent girls and 37%of adolescent boys.)"Occasionally hate family membersI love."(Endorsed true by 44% of adult women and 32% of adult men vs. 72%of ado-lescent girls and 59%of adolescent boys.)"Judged unfairly by family."(Endorsed true by 14%of adult women and 11%of adult men vs. 43% of ado-lescent females and 40%of adolescent males.)These differences in item endorsement patterns between adults and adolescentsmay be meaningfully viewed in reference to the adolescents struggles with indi-viduation from the family and the tasks of identity formation and ego maturation.Tables 1.1and 1.2provide information on abbreviated items that show at least a20%endorsement rate difference between adolescents and adults, separated by gender, asnoted in the normative data for the MMPI-2and MMPI-A.TABLE 1.1Items Showing the Largest Differences for Males in Percentage Endorsement as True Between the Adult(MMPI-2) Normative Sample and the Adolescent (MMPI-A) Normative Sample% Endorsement as TrueMMPI-AItem No.37982128137162208296307371Item ContentFeel restedin morning.Rarely quarrel with family.Like loud parties.Like to pick fights.Been unjustly punished.When bored, stir things up.Often dream about things that shouldntbe talked about.Strange thoughts.Obsessed by terriblewords.Too unsureof future to makeplans.MMPI-268.079.045.016.09.043.028.015.09.012.0MMPI-A34.546.275.347.742.473.062.945.339.442.1Note.

Maturational effects can also be demonstrated on the scale level,particularly in relation to scales F, Pd,Sc,and Ma.These latter scales havetraditionallyshown substantial differences in mean values obtained from adolescent and adult sam-ples (Archer, 1984,1987b). For example, Fig. 1.3 presents the mean raw score values foradolescent and adult males and femaleson the MMPI-260-itemF scale, with findingspresented separately by chronological age. As shown in this figure, mean raw scorevalues on F continue to decrease as the chronological age of the groups increases. It ismost reasonable to interpret these differences as a reflectionof maturational processesrather than levels of psychopathology. Thus, MMPIscales are subject tomaturationaleffects that may serve to obscure or confound the interpretation of psychopathologybased on test scores. In this regard, Achenbach (1978) commented as follows:An often overlooked complication of the search for individual differences in childrenis that developmentaldifferences account for significant variance in almost every mea-surable behavior.One consequence is that measurements repeated on the same subjectsmore than a few weeks apart are likelyto differ as a function of development,even if thesubjects show stability with respect to their rank ordering within their cohort. A secondconsequence is that unless all subjects in a sample are at the same developmental levelwith respect to the behavior in question, individual differences in the behavior may infact reflect differences in developmental level rather than traitlike characteristics. A thirdconsequence is that covariation amongseveralmeasuresmay merelyreflect the variancethat they all sharewith developmentrather than an independent trait. (p. 765)This phenomenon is certainly not limited to adolescent populations, and Colligan,Osborne, Swenson, and Offord (1983) and Colligan and Offord (1992) showed sub-stantial age and maturational effects on standard MMPI scales studied across a broadrange of age groups. Figures 1.4and 1.5, for example, present cross-sectional changes

Reprinted bypermission.)in mean values on the Hs scale and on the Ma scale, respectively, for males and fe-males across age categories ranging from 18/19 to 70+. Similarly,PancoastandArcher(1992) reported substantial differences in mean MMPI profiles for large samples ofadolescents, college students, and adults when the mean values of all three groupsare plotted on the standard reference point of adult norms, as shown in Fig. 1.6.Thus far,maturational influences have been discussed in relation to chronologicalage, but, as will be seen later in the description of the development of the Immaturityscale for the MMPI-A, maturational effects can be clearly demonstrated on MMPIresponse patterns when chronological age is held constant and maturity is measuredmore directly.Another method ofexamining maturational influences on MMPIscale-leveldata—a method that involves looking at patterns of adolescent responses on the Harris-Lingoes subscales profiled on standard adult norms—was used in research byPancoast and Archer (1988). Harris and Lingoes (1955) rationally divided six of theMMPI clinical scales (2,3, 4, 6, 8, and 9) into subscales based on items that appearedlogically similar in content. As discussed later, the Harris-Lingoes subscales arefre-quentlyused in clinicalpracticetodetermine which contentareasofa standardclinicalscale were critically endorsed in producing an overall T-score elevation on the par-ent or standard scale. Adult norms for these subscales have been developed, andadolescent norms are available for the Harris-Lingoes subscales of the MMPI andthe MMPI-A. In the Pancoast and Archer study, adolescent values wereexaminedon adult norms in order to evaluate the ways in which adolescent response patternsmight differ from those typicallyfound for normaladults. Thesemean data are basedon the adolescent normative data collected by Colligan and Offord (1989) at theMayoFoundation and data from a smaller sample of adolescents collected in Virginia in

Figure 1.7 presents findings for the Harris-Lingoes MMPI subscales on adultnorms for MMPI scales D, Hy, and Pd. Results show that subscales related to thePdscale exhibit a general trend toward more extreme elevations than subscales relatedto scales D or Hy. Although most of the subscales for Pd are elevated, the highest ele-vation occurs for Pd1 (Familial Discord), which deals with a struggle against familialcontrols and the perception of marked family conflict. In contrast, there is no eleva-tion for Pd3 (Social Imperturbability), which deals with denial of social anxiety andFIG. 1.7.

Thus, although normal adolescentsexperiences typically involve substantial degrees of family conflict, such conflict ap-pears to be restricted primarily to familial issues and does not include a generalizedsocial discomfort (Pd3), nor does it necessarily include general conflictswith authorityas measured by Pd2 (Authority Conflicts).Figure 1.8presents Harris-Lingoes findings for the remaining three MMPI scales(Pa, Sc, and Ma). Findings from these scales also reveal an interpretable subscale pat-tern. For Pa, the highest subscale is Pa1 (Persecutory Ideas), which primarily dealswith the externalization of responsibility for ones problems and the perception ofbeing treated unfairly and punished by others. On the Scscale, the highest subscaleisSc2 (Lack of Ego Mastery,DefectiveInhibition), which deals with feelingsof restless-ness, hyperactivity, and not being in control of ones impulses. On the Ma scale, theelevated Ma2 (PsychomotorAcceleration) subscale relatesto restlessness,excitement,and pressure for action.Overall, the Harris-Lingoessubscalepatternsuggests that thenormal adolescent, as evaluated by adult norms or standards, istypically preoccupiedwith the familial struggle for independence and is focused on the perception of familyconflicts and that there is a driven, restless, and excited qualityto thisdevelopmentalexperience that often involves a sense of being confined or misunderstood.In summary, the use of the MMPI-A with adolescents requires a developmentalperspective to understand and interpret test findings.This chapter briefly discussedthe dramatic physiological/sexual maturational changes, the changes in cognitiveprocesses, and some of the psychological challenges that occur during adolescence.These changes and challenges contribute to the observed differences between adultsand adolescents in MMPIresponse patterns on the item,scale,and profile level.Recog-nition of the influence of such maturational and developmentalfactors played a major
  • 27. ADOLESCENT DEVELOPMENTAND PSYCHOPATHOLOGY 13role in the decision to createa specialized form of the MMPI for the assessment of ado-lescents, the MMPI-A. One of the main goals of this book is to accuratelydiscriminateand describe those administration, scoring, and interpretive situations that require aunique approach when performed in relation to adolescentclients.ADOLESCENCE AND PSYCHOPATHOLOGYMethodological IssuesIn addition to an awareness of adolescentdevelopmental issues, it is important for theMMPI-A user to develop an understanding of the nature and extentof psychopathol-ogy typically encountered during adolescence. Attempts to estimate the prevalenceof psychiatric disturbance among adolescents, however, are directly affected by sev-eral methodological issues. These include the definition and measures employed toidentify psychiatric disorders among adolescents as well as the methods and infor-mants (parents, teachers, direct psychiatric interviews) on which such estimates arebased. Weissman et al. (1987), for example, evaluated the results from independentinterviews of 220 subjects between the ages of 6 and 23. The diagnostic data for thisstudy were gathered by child interviews using the Schedule for Affective Disordersand Schizophrenia for School-Age Children and were also derived using DSM-III-related interviews with parents and other informants. The authors noted that con-siderable discrepancies were found between parents and childrens reports on thenature and degree of the childrens psychopathology. They found that childrens self-reports or self-descriptions produced evidence of considerably more psychopathol-ogy than did the descriptions of the children provided by their parents. Similar find-ings have also been reported by Reich and Earls (1987) when parental interview re-sults are compared with the results of structured interview techniques used directlywith children and adolescents, such as the Diagnostic Interview for Children andAdolescents (DICA). Further, an investigation by Rosenberg and Joshi (1986) founda significant relationship between the degree of marital discord and discrepancieswithin parental reports of child behavior problems. These researchers reported thatthe greater the marital difficulty, the greater the difference in adults ratings of childbehavior difficulties on the Achenbach and Edelbrock (1983) Child Behavior Check-list (CBCL). Williams, Hearn, Hostetler, and Ben-Porath (1990) compared structuredinterview findings on the Diagnostic Interview Schedule for Children (DISC) withself-report measures of psychopathology that included the MMPI. In addition, sub-jects parents completed the Achenbach and Edelbrock CBCL, and teachers completedthe teacher form of the CBCL. Findings indicated substantial levels of disagreementbetween these measures in the identification of psychologically disturbed subjects.More recently, Cantwell, Lewinsohn, Rohde, and Seeley (1997) evaluated the degreeof agreement between parent and adolescent reports of major psychiatric disordersin adolescents from ages 14 through 18 inclusive. A total of 281 parent-adolescentpairs were interviewed separately regarding psychopathological symptoms using aversion of the K-SADS structured interview. The kappa value for parent-adolescentagreement ranged widely by disorder, from .19for alcohol abuse/dependence to.79for conduct disorder, with an average kappa of .42 across all diagnostic categories.Parent-adolescent agreement was not found to be influenced by adolescents gender,age, parental educational level, age of the onset of the disorder, or the severity of thedisorder. Cantwell and his colleagues concluded, similar to earlier researchers, that
  • 28. 14 CHAPTER 1adolescent self-reports tended to produce higher estimates of psychopathologythandid parental reports, particularlyfor diagnoses that may be classified asinternalizingdisorders such as major depression or anxiety disorders. In contrast, externalizingdisorders such as conduct disorders and oppositional defiant disorder produced rel-atively high rates of agreement, and it appeared viable to base estimates of theselatter disorders on the concensual reports of adolescents and their parents. Thus,it is clear that our estimates of adolescent psychopathology relate not only to howdiagnostic questions are asked but to whom such questions are addressed. Despitethese methodological problems and limitations,it appears possible to offer some gen-eral conclusions concerning the overall prevalence of psychiatric disorders duringadolescence as well as some meaningful observations concerning the form of thesedisorders.Prevalence FindingsOne of the most widely cited studies on the prevalence of child and adolescent psy-chiatric disorders is the "Isle ofWight" study reported by Rutter, Graham, Chadwick,and Yule (1976) and summarized by Graham and Rutter (1985). In the Isle ofWightstudy, a totalpopulation ofover 2,000 British14- and 15-year-olds werescreened usingquestionnaires administered toparents and teacherstoidentify those adolescents with"deviant" adjustment patterns. Adolescents for whom deviant scores were producedon either questionnaire, along with a group of randomly selected control subjects,were then given individual psychiatric assessments involving direct interviewswithparents, teachers, and the adolescents. Each assessment was conducted in a blindfashion in terms of interviewers knowledge of the adolescents membership in thedeviant or control groups. The authors estimated that the 1-year period prevalencerate for psychiatric disorder in their sample was 21%. In general, psychiatric con-ditions appeared to occur with a slightly higher frequency during adolescencethanduring middle childhood (based on the available data for that age period). Certainpsychiatric conditions, however, did show substantial increases during adolescence,including the occurrenceofaffective disorders and depressive conditions.Alongwiththe increase in depression, there was also a dramaticincrease in the frequency of at-tempted and completed suicide.In the United States, Gould, Wunsch-Hitzig,and Dohrenwend (1981) reported thatthe median prevalence rate for clinical maladjustment among children and adoles-cents was 11.8%,based on a review of 25prevalence studies conducted between 1928and 1975. The majority of these studies employed teachers reports as a means ofidentifying psychiatrically disturbed children. Brandenburg, Friedman, and Silver(1989) noted that more recent epidemiologic field studies of child and adolescentpsychopathology have employed diverse methods of case definition and have morefrequently used a multimethod,multistageapproach to caseidentification. Basedonareview of eight recent studies, these authors placed the prevalence estimate ofpsychi-atric disorder in children and adolescents at 14%to 20%. More recently, Breton et al.(1999) used the DISCto evaluate 12- to 14-year-old adolescents and their parents in theQuebec Child Mental Health Survey (QCMHS).Similar toprior studies, these authorsfound that parents and adolescents had the highest rate of agreement for disruptiveor externalizing disorders and the lowest rate of agreement for internalizing disor-ders. The overall 6-monthprevalence rate of psychopathologyreported for the 2,400children and adolescents in this study was 15.8%.Romano,Tremblay, Vitaro,Zocco-lillo, and Pagani (2001) examined psychological functioning in a community sample
  • 29. ADOLESCENT DEVELOPMENTAND PSYCHOPATHOLOGY 15of 1,201 adolescents ages 14 through 17 inclusive. Each of the adolescents and theirmothers were administered the DISC to obtain prevalence estimates of DSM-III-Rdisorders and the amount of perceived impairment associated with each of these dis-orders. Adolescent femaleswere found to report the highest prevalence of psychiatricdisorders (15.5%), in contrastto the prevalence rate of 8.5%reported by male adoles-cents. Compared to their malecounterparts, female adolescents reportedsignificantlyhigher rates of internalizing disorders, including anxiety and depressive disorders.In contrast, the 6-month prevalence of externalizing disorders among male adoles-cents was significantly higher. Roberts, Attkisson, and Rosenblatt (1998) reviewed52 studies conducted between 1963 and 1996 that provided estimates of the overallprevalence of child and adolescent psychiatric disorders. They noted that, whereasthe prevalence estimates for psychopathology among adolescents varied widely, themedian prevalence estimate was 15%,with little evidence that the prevalence of psy-chopathology was significantly changing across time. Kazdin (2000) recently notedevidence of some gender differences in the rate and expression of psychopathology.For example, the prevalence of depression and eating disorders is much higher forfemales than males in the adolescent age grouping.Beyond these prevalence studies of general psychopathology,several studies haveattempted to identify the relative prevalence of specific types of psychiatric symp-tomatology or disorder within adolescent samples. Kashani et al. (1987) utilized bothchild and parent structured interviewsto determinethe prevalenceofpsychiatric dis-order among 150 adolescents selected in a community sample. Roughly 41% werefound to have at least one DSM-III diagnosis, and 19%were judged to have a diag-nosis andto be functionally impaired to a degree indicating the need for psychiatrictreatment. The three most commondiagnoses found in this total sample wereanxietydisorder (8.7%), conduct disorder (8.7%), and depression (8%; this category includedmajor depression and dysthymic disorder).Kashani and Orvaschel (1988)randomly selected 150 adolescents between the agesof 14and 16from a roster of 1,703 students in a Midwestern public school system. Inthis study of anxiety disorders during adolescence, both children and their parentswere interviewed in their homes using the standard and parental interview formsofthe DICA.Interview results were videotaped and scored by three trained raters withestablished interrater reliability. Additionally, participants received several objectivepersonality assessment instruments related to self-concept, affect, and coping. Sev-enteen percent of this sample were found to meet the criteria for one or more formsof psychiatric disorder, and 8.7%were identified as positive cases of anxiety disor-der. The most frequently occurring anxiety disorder in this sample was overanxiousdisorder. Results of this study tend to support the view that anxiety disorders are amajor form of psychopathology in adolescent populations. In other research, Hillard,Slomowitz, and Levi (1987)studied 100 adult and 100 adolescent admissions to a uni-versity hospital psychiatric emergency service. Theauthors reported that adolescentswere less likely to receive diagnoses of personality disorders or psychoses but weremore likely to receive diagnoses involving conduct disorder and adjustment disorder.Further, self-destructive ideation or behavior was present in 40%of the adolescentsseen in the emergency room visits.Lewinsohn, Hops, Roberts, Seeley, and Andrews (1993) recently reported findingsfrom the Oregon Adolescent Depression Project (OADP), a large-scale community-based investigation ofthe epidemiology ofdepression and other psychiatric disordersin a population of approximately 10,200 students in nine high schools in two urbancommunities in west central Oregon. The authors presented data on the prevalence
  • 30. 16 CHAPTER 1of psychiatric disorders in the 14- to 18-year-old age range, which coincidentallycorresponds to the age grouping employed in the MMPI-A normative sample. Ad-ditionally, an important characteristic of this study was that it relied exclusively ondiagnostic information provided by adolescents in structured interviews and stan-dardized questionnaires. Overall, this study indicated that 11.2%of girls and 7.8% ofboys met the criteria for a current DSM-III-R psychiatric diagnosis based on interviewfindings. Among these psychiatric diagnoses, major depression, unipolar depression,anxiety disorders, and substance abuse disorders were particularly prevalent. In gen-eral, female students were more likely than male students to receive diagnoses ofunipolar depression, anxiety disorders, eating disorders, and adjustment disorders,whereas boys were more likely to receive a diagnosis of disruptive behavior disorder.Lewinsohn, Klein, and Seeley (1995) followed up this research by evaluating the self-reports of 1,709 adolescents between the ages of 14and 18on the SADS to specificallyfocus on the prevalence and clinical characteristics of bipolar and manic disorder.The lifetime prevalence of bipolar disorder in this Oregon sample (primarily bipo-lar disorder and cyclothymia)was approximately 1%.Costello and colleagues (1996)found a 3-month prevalence rate for any DSM-III-R Axis I disorder of 20.3% in asample of 9-, 11-, and 13-year-old boys and girls in the southeastern United States.The more common diagnoses were anxiety disorders (5.7%), enuresis (5.1%), tic dis-orders (4.2%), conduct disorders (3.3%), oppositional defiant disorders (2.7%), andhyperactivity (1.9%).The issue of suicidal ideation and behavior has received special focus in recentstudies of adolescence. Friedman, Asnis, Boeck, and DiFiore (1987), for example, in-vestigated 300 high school students who were anonymously surveyed regarding theirexperiences with suicidal ideation and behaviors. Roughly53%of this sample statedthat they had thought about killing themselves but did not actually try, and 9%ofthe total sample stated that they had attempted suicide at least once. These find-ings indicated that suicidal ideation is relatively common among adolescents but alsosuggested that actual suicide attempts were disturbingly frequent.Inthis regard, Kim-mel and Weiner (1985) noted that suicide is the third most common cause of death foradolescents aged 15 to 19,with the suicide rate particularly marked for White maleadolescents. Further, the rate of adolescent suicide has nearly doubled from 1960 to1975, and about 10%of adolescents seen in mental health clinicsand more than 25% ofthose admitted to psychiatric units in general hospitals have threatened or attemptedsuicide (Kimmel& Weiner, 1985). Boys appear 4 times more likely than girls to actu-ally kill themselves, whereas girls appear three times more likely to make a suicideattempt.Within the MMPI-A normative sample, 21% of boys and 38% of girls respondedtrue to abbreviated Item 177, "Think about killing self."In 1996 the age-specific U.S.mortality rate for suicide was 1.6per 100,000 for 10-to14-year-olds, and 9.5per 100,000for adolescents in the 15- to 19-year-old age grouping.In this latter age grouping, boys were 4 times more likely than girls to commit suicide,while girls were twice as likely to attempt suicide (Center for Disease Control andPrevention [CDC], 1999). In addition, there have been some important demographicpatterns recently emerging from national studies on mortality rates. For example,Hispanic high school students are more likely than students from other ethnic back-grounds to attempt suicide (CDC, 1999). The rate among White adolescent malesappears to have reached a peak in the late 1980s (18per 100,000 in 1996) and has sincedeclined to approximately 16per 100,000in 1977 (CDC, 1999).In contrast, the suiciderate among Black male adolescents has increased substantially across the same period
  • 31. ADOLESCENT DEVELOPMENTAND PSYCHOPATHOLOGY 17(7.1per 100,000in 1966versus 11.4 per 100,000in 1997; CDC, 1999).Further, from 1979through 1992, the Native American male adolescent and young adult suicide rate asreported by the Indian Health Service Areas was the highest in the United States,with a suicide rate of 62 per 100,000 (Wallace, Calhoun, Powell, ONeil, & James,1996).Several general conclusions seem possible from these and other investigations ofpsychopathology during adolescence. First, the majority of adolescents do not showevidence of psychopathology that would result in psychiatric diagnosis. The rateofpsychopathology during adolescence appears "only slightly higher than that foundearlier in childhood or later in life" (Petersen & Hamburg, 1986, p. 491).There is evi-dence that the frequency and severityofdepression does increaseduring adolescence,and there is a marked increase in both suicide attempts and suicide fatalities duringthis period of development. Several disorders tend to make their first appearanceduring adolescence, including anorexia nervosa, bipolar illness, bulimia, obsessive-compulsive disorder, schizophrenia, and substance abuse, although other disorders,such as enuresis and encopresis, become less frequent (Burke, Burke, Regier, &Rae,1990; Graham & Rutter, 1985). Although the rate of anxiety disorders and conductdisorders may show little change during adolescence, the expression of symptomsrelated to these disorders does change. The rate of specific phobic disorders appearsto decrease during adolescence, whereas conduct disorders more frequently involveviolence (Graham& Rutter, 1985; Petersen & Hamburg, 1986).The "Stormand Stress" Model and PsychopathologyG. Stanley Hall (1904),considered by many to be the father of child psychology in theUnited States, was the formulator of the Sturmund Drang (Storm and Stress) modelofadolescent development. This model, consistent with the view of Anna Freud (1958),postulates that adolescence is typically accompaniedby emotional upheavals and be-havioral turbulence. Freud held that adolescents who did not demonstrate turbulentfeatures of adjustment were at risk for the development of serious psychopathologicalsymptoms in adulthood. Freuds formulationof this view is represented in her state-ment that "the upholding of a steady equilibrium during the process [of adolescence]is, in itself, abnormal" (p. 275).Freuds view of adolescent development may be bestillustrated by the following quotation:I take it that it is normalfor an adolescent to behave for a considerable length oftime in aninconsistent and unpredictable manner; to fight his impulses and to accept them; to wardthem off successfully and to be overrun by them; to love his parents and to hate them; torevolt against them and to be dependent on them; to be deeply ashamed to acknowledgehis mother before others and,unexpectedly, to desire heart-to-heart talks with her;tothrive on imitation and identification with others while searching unceasingly forhis ownidentity; to be more idealistic, artistic, generous, unselfish than he will ever be again, butalso the opposite—self-centered, egoistic, calculating. Such fluctuations between extremeopposites wouldbe deemed highly abnormal at any other time of life. At this time theymay signify no more than that an adult structure of personality takes a long time toemerge, that the ego of the individual in question doesnot cease to experiment and is inno hurry to close down onpossibilities.(p. 276)Blos (1962)also felt that the psychiatric symptoms typically presented during ado-lescence were often ill-defined, unstable, and transitory in nature and did not signify
  • 32. 18 CHAPTER 1stable markers of psychiatric illness. Similarly, Erikson (1956) proposed that the ado-lescents struggles for self-definition frequently resulted in deviations from expectedor normal behavior, which he termed identity diffusion or identity confusion and differ-entiated from stable psychopathology.Many have objected to the Storm and Stress view of adolescent development,particularly the implication that normal adolescent development is characterized bysubstantial turbulence and lability. Bandura (1964), for example, argued that manyadolescents establish more trusting and relaxed relations with their parents duringadolescence while also increasing contact with peer groups. Thus, the shifting awayfrom the nuclear family to the peer group is not necessarily and inevitably a sourceof family tension. Offer and Offer (1975) investigated suburban male adolescents andfound that, although transient episodes ofnondisabling depression and anxiety werecommon, only 20%ofadolescents demonstrated moderate to severe symptomatology.This estimate, as we have seen, is generally consistent with reports of the prevalenceof significant psychopathology in adolescent populations. Further, these investiga-tors also found that 20%of their sample did not appear to experience any significantturmoil during their adolescent development and were able to successfully cope withthe wide variety of challenges it presented.Rutter et al. (1976) examined the concept of adolescent turmoil within the contextof their findings in the Isle of Wight study of 14- and 15-year-olds. These authorsconcluded that parent-child alienation was not common among adolescents in generalbut rather appeared restricted to adolescents who already showed signs of psychiatricproblems. On the other hand, "inner turmoil," which was defined by the researchersas feelings of misery and self-depreciation, appeared to be frequently associated withadolescence. The authors concluded that "adolescent turmoil is a fact, not a fiction,but its psychiatric importance has probably been overestimated in the past.Certainlyit would be most unwise to assume that adolescents will grow out of their problemsto a greater extent than do younger children" (p.55).In their review of the literature on adolescent psychopathology, Weiner and DelGaudio (1976) offered the following three conclusions: First, psychiatric symptomsare not a normal feature of adolescence; second, boundaries between normal andabnormal adolescence may be drawn despite inherent difficulties; and third, ratherthan apassingphase,psychological disturbance during adolescence typically requirestreatment for remission. This concept has also been expressed by Kimmeland Weiner(1985) in their statement that, "by and large, people remain basicallythe same in howthey think, handle interpersonal relationships, and are perceived by others. Forbetteror worse, adults tend to display many of the same personality characteristics andsame relative level of adjustment they did as adolescents" (p.449).Viewed within the context of our data on the prevalence of psychiatric disordersduring adolescence, the debate surrounding the stability of adolescent symptoma-tology appears to center on the distinction between psychopathology as defined byDSM-IV categories and terms such as turbulence and Storm and Stress. Prevalenceestimates of psychopathology during adolescence appear to fall within a reasonablystable range of 12%to 22%(NationalInstituteof MentalHealth, 1990;Powers, Hauser,& Kilner,1989). The adolescents identified in these studies do, in fact, appear to sufferfrom stable DSM-IV-related disorders that would not be expected to remit withoutactive and effective treatment.For example, it is estimated that almost half ofchildrenor adolescents receiving conduct disorder diagnoses will become antisocial adultsand that untreated depression and anxiety disorders during adolescence often persistinto adulthood (National Institute of Mental Health, 1990). Further, a recent study by
  • 33. ADOLESCENT DEVELOPMENTAND PSYCHOPATHOLOGY 19Hofstra, Van der Ende, and Verhulst (2002) also demonstrated a continuity betweenchild and adult psychopathology in a sample of 1,578 children and adolescents se-lected from the Dutch general populationand followed up 14 years later. These authorsfound that childhood behavior and emotional problems were related to DSM-IV di-agnoses in adulthood. Thestrongest associations between specificchildhood problemareas and adult diagnoses were found for social problems in girls, which were gener-ally predictive ofthe occurrenceof DSM-IV disorders. Rule-breakingbehavior in boyswas also predictive oflater mood disorder and/or disruptive disorders in adulthood.On the other hand, many more adolescents go through a period of turbulence andlability that would notqualify as a DSM-IV disorder but is commonly associated withaccomplishing the mastery of the various adaptational challenges presented duringadolescence. Although it is clear that the dividing line between these two groups isfrequently blurred and difficult to discern, it serves little purpose to view these groupsas homogeneous in terms of the severity of their symptoms or the implications forlong-term adjustment. It might be expected that MMPI-A test results, based on con-temporary adolescent norms for this instrument, should prove of substantial value tothe clinician in rendering this important diagnosticdistinction.Stability of Adolescents MMPI/MMPI-AFeaturesWhether adolescent symptomatology is stable or transitory, it appears relatively clearthat those features and characteristics measured by the MMPI or MMPI-A in theassessment of adolescents serve to accurately describe the teenagers at the momentof testing. Adolescents test scores often do not, however, provide the types of datanecessary to make accurate long-term predictions concerning psychopathology orpersonality functioning. The MMPI/MMPI-A is best used as a means of deriving anoverall estimate and current description of adolescent psychopathology rather thanas a tool for making long-range predictions regarding future adjustment.An illustration of the variability inherent in adolescent personality structure maybe found in data reported by Hathaway and Monachesi (1963) in their classic studyof adolescents MMPI response patterns. These authors evaluated 15,300 Grade 9children within Minnesota school systems between 1948 and 1954 and retested 3,856students when they reached Grade 12during the 1956-1957 school year. Examiningadolescents who were tested in both the 9th and 12th grade, Hathaway and Monach-esi found test-retest correlation coefficients ranging from the low to mid .30s on scalessuch as Pd and Pato values in the high .50s and low .60s for scale Si. Hathaway andMonachesi concluded that these correlations underscored the degree of change thatmay occur within an adolescents MMPI profile, reflecting the fluid nature of ado-lescents overall personality organization.Hathaway and Monachesinoted, however,that the stability of an adolescents profile tends to increase when T-score values aresubstantially elevated in the initial testing. Thus, clinically elevated profile character-istics may be subject to less change than marginally elevated profile features. Evenin clinical or preclinical adolescent populations, however, substantial change oftenoccurs in MMPI profile features. Similar to the study by Hathaway and Monachesi,Lowman, Galinsky,and Gray-Little (1980) reported that relatively pathologicalMMPIprofiles of eighth graders in a rural county in North Carolina were generally not pre-dictive of level of psychological disturbance or achievement for this sample at youngadulthood.Gottesman and Hanson (1990) reported pilot findings from a study that has con-tinued to follow the Hathaway and Monachesi data set of adolescents administered

These authors located individuals ad-mitted to Minnesota psychiatrichospitals or correctional facilities more than 20yearsfollowing their initial ninth-grade MMPI assessment. The researchers identified 183men and women admitted to these public institutions, of which 26 cases were iden-tified as schizophrenics. Figure 1.9 shows the MMPI profiles of 16 boys who wereevaluated in the ninth grade and later received a diagnosis of schizophrenia and agroup of normal matched control subjects from the ninth-grade testing. Figure 1.10shows similar findings for 10girls who were evaluated in the ninth-grade sample andlater manifested schizophrenia and their matched cohorts. These remarkable data il-lustrate the difficulties involved in attempting to make long-term predictions fromMMPI profiles of adolescents. Differences did occur in these ninth-grade samplesbetween groups of adolescents who did and did not develop schizophrenia. Thesedifferences, however, clearly would not permit specific diagnostic predictions. Asnoted by Hanson, Gottesman, and Heston (1990)in reference to these data, an effortto predict schizophrenia from ninth-grade test results would have been an exercise infutility.Hathaway and Monachesi (1963) indicated that MMPI profiles produced by anadolescent often change across time because of the "transient organization of the per-sonality" during adolescence.Theynoted thatsuch psychometricchanges, ratherthanindicating difficulties in test construction, indicate the sensitivity of instruments suchas the MMPI to ongoing change during the maturationalprocess. These phenomenado, however, limit the utility of tests such as the MMPI when such instruments areapplied in a long-range predictive rather than descriptive manner.

Copyright © by I. I.Gottesman. Reprinted by permission.)SUMMARYThis chapter has provided a brief review of adolescent development and issues re-lated to developmental psychopathology during this maturational stage. As is dis-cussed in the followingchapters in this text,the MMPI-A presents a variety offeaturesthat could potentially improve the identification and description of psychopathologyamong adolescents as compared with the original test instrument. For example, thedevelopment of the MMPI-A included extensiverevisions of the original MMPI itempool to improve item clarity and relevance for adolescents. New items were also in-cluded in the MMPI-A that are related to forms of psychopathology of importanceduring adolescent development, including suicidalideation, alcohol and drug abuse,and eating disorders. On the scale level, the MMPI-Ahas incorporated new measuresof psychopathology of particular relevance to adolescents, including conduct disor-der, schoolproblems, depression, anxiety, and immaturity.Additionally, theMMPI-Adevelopment included the collectionof an adolescent normativesample of 1,620ado-lescents representing various geographic, socioeconomic, and ethnic groups. Therelease of an "official" set of adolescent norms for the MMPI-A by the Universityof Minnesota Press has substantially assisted in eliminating the inappropriate butwidespread practice of applying adult norms in the interpretation of adolescent re-sponse patterns.Finally, the MMPI-A profile sheet contains a "gray zone" area denoting a rangeof marginal or transitional elevations in place of the traditional use of a specific T-score designation as a cutoff between normal range scores and clinically elevated
  • 36. 22 CHAPTER 1values. This use of a range of T-scores to mark the transition between normal rangevalues and clinical values is particularly important in the assessment of adolescents,where the conceptual and psychometric dividing line between normalcy and pathol-ogy may be less clear than during adult development. Thus, the MMPI-A containsa number of features that may improve the assessment of adolescent psychopathol-ogy when employed by a clinician who is sensitive to developmental issues in thispopulation.
  • 37. 2Development of the MMPI and the MMPI-ADEVELOPMENT OF THE MMPIWork on the instrument that was to become the Minnesota Multiphasic PersonalityInventory (MMPI) was begun in 1937by Stark R. Hathaway, a psychologist, and J.C.McKinley, a neuropsychiatrist. The test authors were motivated to develop a "per-sonality inventory" by their pursuit of several objectives. First, they had noticed thata large proportion of patients presenting for medical treatment manifested "one ormore complaints that turn out tobepsychoneurotic innature" (McKinley & Hathaway,1943, p. 161). The two test authors sought to develop an instrument that would beuseful in identifying and describing these patients in a manner that was more effi-cient and effective than the psychiatric interview techniques traditionally used forpsychological evaluations of medical patients. Apparently, Hathaway also believedthat such an instrument might assist researchers in evaluating the efficacy of newtreatment interventions by allowing for the systematic matching and evaluation oftreatment groups. For example, Hathaway (1964), in reference to the use of insulintherapy, which was prevalent in the 1930s, noted:There was no way that our hospital staff could select a group of patients for the newtreatment who would be surely comparable in diagnosis and severity of illness to thosefrom some other setting. Itbecame an obvious possibility that one might devise a person-ality test which, like intelligence tests, would somehow stabilize the identification of theillness and provide an estimate of its severity. Toward this problem the MMPI researchwas initiated. (p.205)Finally, Hathaway was also interested in the development ofa personality assessmentinstrument that could assess changes in symptomatology across time. Further, whensuch a measure was administered at various stages of the treatment process, it wouldprovide the clinician with an index of therapeutic change. In this regard, Hathaway(1965) stated that the MMPIwas designed to serve as an "objective aid in the routinepsychiatric case workup ofadult patients and as a method ofdetermining the severityof the condition. As a corollary to this, the inventory was expected to provide anobjective estimate of psychotherapeutic effect and other changes in the severity oftheir conditions over time" (p.463).23
  • 38. 24 CHAPTER 2As noted by Colligan et al. (1983),the first published referenceto the MMPI projectwas listed as a footnote to a 1939 paper (Hathaway, 1939). The MMPI was initiallyreferred to as the "Medical and Psychiatric Inventory," later titled the "MultiphasicPersonality Schedule" in a 1940paper by Hathaway and McKinley, and finally desig-nated the Minnesota Multiphasic Personality Inventory in the 1943publication of theinstrument by the University of Minnesota Press. Hathaway and McKinley had initialdifficulty in finding a publisher for the MMPI, and Hathaway noted that "Dr. McKin-ley and Ihad faith sufficient to carryus through several rejectionsbefore the Universityof Minnesota Press finally undertook publication" (cited in Dahlstrom &Welsh,1960,p. vii). Despite this humble beginning, the MMPI has become the most widely usedobjective personality assessment instrument across a wide variety of clinical settings(Lees-Haley, Smith, Williams,&Dunn, 1996;Lubin,Larsen,&Matarazzo, 1984;Lubin,Larsen, Matarazzo, & Seever, 1985; Lubin, Wallis, & Paine, 1971; Piotrowski &Keller,1989, 1992). Butcher (1987a) estimated that over 10,000 books and articles have beenproduced on the MMPI, and Butcher and Owen (1978) reported that 84% of all re-search on personality inventory instruments has been focused on the MMPI.Butcherand Williams (2000) noted that by 1989 there were over 140MMPI translations in 46countries.Historical ContextIn their development of the MMPI, Hathaway and McKinleywere sensitive to manyof the problems that existed in the personality inventories of that era. For example, theWoodworth Personal Data Sheet (Woodworth, 1920)was a 169-item self-ratingscaledesigned to detect neurotic maladjustment used in screening draftees during WorldWar I. Respondents answered yes or no to the series of questions, and the total num-ber of positive answers was used to determine whether the individual was referredfor additional psychiatric interview. Following the development of the WoodworthPersonal Data Sheet, several other rationally developed questionnaires were created,including the Bell Adjustment Inventory (Bell, 1934) and the Bernreuter PersonalityInventory (Bernreuter, 1933). Rational scale construction involves the selection of itemsthat logically or rationally appear to measure important areas. The selection of theseitems is based on the developers theory, clinical experience, and intuition. A fun-damental assumption inherent in this test construction method was that the itemsactually measured what the authors assumed they measured. Over time, however, itbecame clear that items selected exclusively on a rational basis were not always in-dicative of deviant behavior and that test subjects did not always respond accuratelyand honestly to test instruments. As noted by Greene (1980), critical studies and re-views by several authors, including Landis and Katz (1934)and Super (1942),stronglycriticized the effectiveness of these rationallyderived personality inventories. For ex-ample, test scores produced by normal subjects and subjects in clinical settings wereoften found to show little difference on these measures.Hathaway and McKinley were also aware of the rudimentary efforts to developvalidity scales as employed in the Humm-Wadsworth Temperament Scale (Humm &Wadsworth, 1935).This symptom checklistmeasure contained a "no count" score con-sisting of the number of items or symptoms denied (i.e., not endorsed by the subject)in responding to the instrument. Thus, a high no count score was seen as reflectiveof a subject who was excessively guarded or defensive, whereas a very low no countscore might indicate a tendency to exaggerate or overreport symptoms.Additionally,Hathaway and McKinleybegan work on the MMPI following Strongs (1927, 1943)
  • 39. DEVELOPMENT OF THE MMPI AND THE MMPI-A 25use of criterion groups in the development of a vocational or occupational-interestinventory (i.e., the Strong VocationalInterest Blank). Thus, Hathaway and McKinleyhad available a model of scale construction that stood in contrast to the rational de-velopment procedures that had typically been used for personality measures. Theywere also motivated by the need for an inventory that would be of practical use inclinical settings. Bythe late 1930s, much of personality assessment was seen as irrele-vant by applied psychologists, as acknowledged by Hathaway (1965) in his commentthat "it was so widely accepted that personality inventories were valueless that someprogram directors did not feel that any course work in their nature and interpretationwas worth the effort" (p.461).Development Methods for the Original MMPIGreene (2000) dramatically noted that "out of the psychiatric wilderness of the early1930s appeared two men, Stark Hathaway and J.C.McKinley, who, under the bannerof empiricism, waged anew battle for the scientific advancementofpersonality assess-ment" (p. 5). The developmental procedures used in the creation of the MMPI havebeen extensively documented by authors such as Colligan et al. (1983), Dahlstrom,Welsh, and Dahlstrom (1972, 1975), Friedman, Webb, and Lewak (1989), Friedman,Lewak, Webb,and Nichols (2001), Graham (2000), and Greene (2000). The proceduresemployed by Hathaway and McKinleyare therefore only briefly summarized in thistext.A salient feature of Hathaway and McKinleys approach to the creation of theMMPI was their use of the criterion keying method, or the empirical method of inven-tory construction. Indeed, the MMPI is usually cited as the outstanding example ofthis test construction method (e.g., Anastasi, 1982). In the criterion keying approach,items are presented to two or more groups ofsubjects. One subject group serves as thecriterion group, the group that manifests a defining diagnosis or characteristic thatthe test is meant to measure, and one or more others act as comparison groups, whichdo not manifest the trait or characteristicunder study. Responses of the criterion andcomparison groups are compared, and items are then selected for inventory mem-bership that empirically demonstrate significant differences in response frequency.As noted by Friedman et al. (2001), scales constructed utilizing this methodology areusually named after the criterion group. For example, if the criterion group consistedof clinically depressed patients, the scalewould probably be labeled a Depression scale.Further, scoring isusually accomplished by assigning onepoint to eachitem answeredin the direction that is more frequently endorsed by criterion subjects. Additionally,the higher an individual scores on this type of measure, the more items he or she hasanswered in a direction consistent with that of the criterion group members.Much as earlier researchers did, Hathaway and McKinley began their construc-tion of the MMPIby generating an extensive pool of items from which various scalesmight be constructed. Specifically, they created nearly 1,000self-referenced statementsinspired from a wide variety ofsources, including psychiatric examination forms, psy-chiatric textbooks, previously published scales ofpersonality and social attitudes, andtheir own clinicalexperience (Hathaway & McKinley, 1940).Theythen reduced this listto 504items by deleting items that duplicated content or that the authorssubjectivelyfelt had relatively little significance or value. Thus, the authors used a subjective andrational method to createthe initial item pool. Tosimplify the task of identifying itemduplication, Hathaway and McKinley constructed 25 content categories (Table 2.1)for the original MMPIitem pool. In addition to the items shown in Table2.1,55 items

These items were then employedto construct scales by comparing the item responses of normal individuals againstthose of psychiatric patients who held membership in relatively homogeneous clini-cal criterion groups.Normative GroupsThe normal criterion group primarily used in developing the MMPI consisted ofindividuals (N = 724) who were visiting friends or relatives receiving treatment atthe University of Minnesota Hospital. These subjects, aged 16years and older, wereapproached in the halls or waiting rooms of the hospital and invited to participate inthe research project if preliminary screening indicated that they were not receivingtreatment for any psychiatric or medical illness. The overall age, gender, and maritalstatus of this University of Minnesota group were reported to be comparable to the1930 U.S. Census findings (Hathaway & McKinley, 1940). Dahlstrom et al. (1972)described the Minnesota normative sample as follows: "In 1940, such a Minnesotanormal adult was about thirty-five years old, was married, lived in a small town
  • 41. DEVELOPMENT OF THE MMPI AND THE MMPI-A 27or rural area, had had eight years of general schooling, and worked at a skilled orsemiskilled trade (or was married to a man with such an occupational level)" (p.8).In addition, Hathaway and McKinley collected data from two other samples of"normals." One of these samples consisted of 265 high school graduates who werecoming to the University of Minnesota Testing Bureau for college counseling andguidance, and 265individuals who were contacted through the local WorksProgressAdministration (WPA), a federally funded employment project. This latter group con-sisted ofskilled workerswho were "all white-collarworkersand were used ascontrolsfor urban background and socioeconomiclevel" (Dahlstrom &Welsh, 1960, p.46).Colligan et al. (1983)noted that the original normative data collected by Hathawayand McKinleyare no longer available. However, a subsample ofthese data, referred toas the Minnesota normal "purified" sample, was developed by Hathaway and Briggs(1957). The Hathaway and Briggssample consists of225males and 315femalesdrawnfrom the general Minnesota normal sample. These data have been preserved andwere the basis for the development of Appendix K in the MMPI-2 Manual (Butcheret al., 1989). Appendix Kprovides T-scorevalues, based on the purified sample of theoriginal Hathaway-McKinley norms, for MMPI-2basic scales.Clinical ScalesThe clinical criterion groups utilized by Hathaway and McKinley defined the eightbasic MMPI scales and consisted of carefully selected psychiatric patients in the fol-lowing diagnostic categories: Hypochondriasis (scale 1), Depression (scale2),Hysteria(scale 3), Psychopathic Deviant (scale 4), Paranoia (scale 6), Psychasthenia (scale 7),Schizophrenia (scale 8), and Hypomania (scale 9).Detailed descriptions of these clini-cal criteriongroups wereprovided by Colligan et al. (1983),Dahlstromand Dahlstrom(1980), Dahlstrom et al. (1972), and Greene (1980, 2000). In addition, a group con-sisting of "homosexual invert males" was employed by Hathaway and McKinleyin the development of the Masculinity-Femininity scale (scale 5). Finally, the SocialIntroversion-Extroversion scale, developed by Drake (1946), was eventually addedas the 10th basic scale of the MMPI (scale 0). The Si scale remains the only standardscale that was developed outside of the original Hathaway group and the only scalefor which a psychiatriccriteriongroup was not obtained (Colligan et al., 1983).Validity ScalesIn addition to the 10standard clinical scales, Hathaway and McKinleyalso developed4 validity scales for the MMPI,the purpose ofwhich was to detect deviant test-takingattitudes or response sets. These measures included the Cannot Sayor (?)scale, whichwas simply the total number of MMPI items that were either omitted or endorsed asboth true and false, and the L or Lie scale, which consisted of 15 rationally deriveditems that present common human faults or foibles. The L scale was designed todetect crude attempts to present oneself in an unrealisticallyfavorable manner. TheFscale was composed of 64 items that were selected because they were endorsed in aparticular direction by 10%or fewer of the Minnesota normal group. Hathaway andMcKinley (1943)suggested that high scores on the Fscale would imply that the clinicalscale profilewas invalid because the subject was careless or unable to comprehend theitems orbecause extensive scoring errors had occurred. TheT-scoreconversion valuesfor F,like those for the Cannot Say scale and the Lscale, were arbitrarily assigned by
  • 42. 28 CHAPTER2McKinley and Hathaway rather than based on a linear transformation of raw scoredata from the Minnesota normal sample.The final validity scale developed for the MMPI was the K scale. The K scale wasdeveloped by selecting 25 male and 25 female psychiatric patients who producednormal-range clinicalscale values (i.e.,T-scorevalues < 69on all clinical scales). Thesesubjects, therefore, could be considered to be false negatives (Meehl & Hathaway,1946). The profiles of these false-negative patients were compared with the responsesof the Minnesota normal cases, that is, true negatives. Item analysis revealed 22 itemsthat discriminated the "true- and false-negativeprofiles in their item endorsements byat least 30%" (Dahlstrom et al., 1972, p. 124). Eight additional items were eventuallyadded to the K scale to aid in accurately discriminating depressed and schizophrenicpatients from subjectsin the normative group. The main function of the K scale was toimprove the discriminative power of the clinical scales in detecting psychopathology,and varying proportions ofthe Kscale raw score totalhave traditionallybeen added toscales 1,4, 7,8, and 9when using the K-correctionprocedure with adult respondents.The standard validity and clinical scales are discussed in more detail in later chaptersdealing with validity assessment and clinical interpretation strategies.Important FeaturesBefore leaving the topic of the development of the original form of the MMPI, twogeneral points should be made regarding characteristics of the instrument that havelargely contributed to its popularity among clinical practitioners. First, as discussedby Graham (2000), it rapidly became apparent following the publication of the MMPIthat its interpretation was considerably more complex than was initially anticipated.Rather than producing an elevated score on a single clinical scale, many psychiatricpatients produced multiple elevations involving several scales. Thus, forexample, de-pressed patients often produced elevations on the Depression scale but also obtainedhigh scores on other standard clinicalscales of this instrument. According toGraham,this phenomenon resulted from several factors, including a high degree of intercor-relation among the MMPI standard scales. Indeed, a variety of approaches have beenused with MMPI data over the past 40 years in attempts to yield useful diagnosticinformation. No approach has produced more than modest correspondence betweenMMPI-derived diagnoses and psychiatric diagnoses based on clinical judgment orstandard diagnostic interviews (e.g., Pancoast, Archer, & Gordon, 1988).For these reasons, the MMPI has come to be used in a manner different from thatoriginally envisioned by Hathaway and McKinley, particularly in terms of profileinterpretation. Specifically, the usefulness of the particular scale labels or names hasbeen deemphasized, a practice reflected in the tendency of MMPIinterpreters to referto MMPI scales by their numbers rather than criterion group labels (e.g., references toscale 7rather than to the Psychasthenia scale). Accompanying this change, numerousresearchers have set about to establish the meaning ofclinicalscales through extensiveclinical correlate research. In this research approach, the actual extra test correlatesof the MMPI scales are identified through empirical research efforts based on carefulstudies ofindividuals who produce certain patterns ofMMPIscale elevations. The netimpact of this shift in interpretive focus has been that the MMPI is standardly usedas a descriptive instrument and that this descriptive capacity of the MMPI is based onthe accumulation of numerous research studies concerning the test characteristics ofspecific MMPI configuration groups. As noted by Graham (2000):
  • 43. DEVELOPMENT OF THE MMPIAND THE MMPI-A 29Thus, even though the MMPI was not particularly successful in terms of its originalpurpose (differential diagnosis of clinical groups believed in the 1930s to be discretepsychiatric types), it has proven possible, subsequently, to use the test to generate de-scriptions of and inferences about individuals (normalpersons and patients)on the basisof their own profiles. It is this behavioral description approach to the utilization of thetest in everyday practicethat has led to its great popularity among practicing clinicians.(p. 6)It should also be noted that this approach to the interpretation of the MMPI haslinked the usefulness ofthe test not to aspects ofits original psychometric constructionbut rather to the massive accumulation ofresearch literature that has been developedfor this test instrument. Thus, the major clinical value of the MMPI lies in what wehave come to know about what test results "mean."A second important feature of the MMPI concerns the development of a broadvariety of validity scales and indices through which to evaluate the consistency andaccuracy of the clients self-reports. The MMPI was among the first personality as-sessment instruments to strongly emphasize the use of validity scales to assist indetermining the interpretability of clinical test findings. Thus, the MMPI interpretercan estimate the degree to which test findings are influenced by a number offactorsrelated to the respondents willingness and capacity to respond in a valid manner.This feature,in turn, has allowed the extension of the MMPIto assessment issues notoriginally envisioned by Hathaway and McKinley.These latter tasks have includedthe psychological screening of individuals in personnel and forensic settings, whichdiffer substantially from the typicalpsychological treatment setting. Beyond the orig-inal four validity scales, numerous other MMPI measures have been subsequentlydeveloped to assess issues related to technical profile validity (e.g., the Carelessnessscale and the Test-Retest Index). Many of these have been reviewed extensively byGreene (1989a, 2000).MMPI-2The MMPI was updated and restandardized, and a new version, the MMPI-2, wasreleased in 1989 (Butcher et al., 1989), 46 years after the original publication of thisinstrument. The revision involved a modernization of the content and language oftest items, the elimination of objectionable items, and the creation of new scales, in-cluding a series of 15content scales (Archer, 1992c; Nichols, 1992). The developmentof the MMPI-2 also involved the collection of a nationally representative norma-tive data sample of 2,600 adult men and women throughout the United States. TheMMPI-2 contains 567 items that heavily overlap with items from both the originalversion of the MMPI and the adolescent version (MMPI-A). Several comprehensiveguides to the MMPI-2 are now available (Butcher, 1990; Friedman et al., 2001;Gra-ham, 2000; Greene, 2000; Nichols, 2001),and a text has been specificallydevoted to adescription of the MMPI-2content scales (Butcher,Graham, Williams, & Ben-Porath,1990). In addition, a research base is gradually developing for the interpretation ofMMPI-2 profile codes (e.g., Archer, Griffin, & Aiduk, 1995; Graham, Ben-Porath, &McNulty, 1999). It should be specifically noted, however, that the MMPI-2 was de-signed and normed for individuals who are 18 years ofage or older. Adolescent normswere not developed for the MMPI-2, nor was it intended for use in the assessment ofadolescents.
  • 44. 30 CHAPTER 2USE OF THE MMPI WITH ADOLESCENTSThe application of the MMPI to adolescent populations for both clinical and researchpurposes occurred early in the development of this instrument. Although the MMPIwas originally intended for administration to individuals who were 16 years of ageor older, Dahlstrom et al. (1972) noted that the test could be used effectively with"bright children as young as 12" (p. 21). The delineation of age 12 as the lower limitfor administration of the MMPI was probably related to the estimate that a sixth-grade reading level was a prerequisite for understanding the MMPIitem pool (Archer,1987b).Early ApplicationsThe first research application of the MMPIwith adolescents appears to have occurredin 1941, 2 years prior to the formal publication of the MMPI in 1943. Using the in-strument, Dora Capwell (1945a) demonstrated its ability to accurately discriminatebetween groups of delinquent and nondelinquent adolescent girls based on Pd scaleelevation. Further, the MMPI Pd scale differences between these groups were main-tained in a follow-up study that reevaluated MMPIprofiles 4 to 15months followingthe initial MMPI administration (Capwell, 1945b). Earlystudies by Monachesi (1948,1950) also served to provide validity data concerning the Pd scale by demonstratingthat delinquent boys scored significantly higher on this measure than normal maleadolescents. In addition, the 1950 study by Monachesi included a sample of incar-cerated female delinquents who produced findings that replicated the earlier reportsof Capwell. Following these initial studies, the MMPI was used with adolescents invarious attempts to predict, diagnose, and plan treatment programs for delinquentadolescents (e.g., Ball, 1962; Hathaway & Monachesi, 1951, 1952). Pursuing this re-search topic, Hathaway and Monachesi eventually collected the largest MMPI dataset ever obtained on adolescents, in a longitudinal study of the relationshipbetweenMMPI findings and delinquent behaviors.Hathaway and Monachesi administered the MMPI to 3,971 Minnesota ninth-graders during the 1947-1948 school year in a study that served as a prelude to thecollection of a larger sample, termed the statewide sample. The statewide sample wascollected during the spring of 1954, when Hathaway and Monachesi tested 11,329ninth graders in 86communities in Minnesota.Their combined samples involved ap-proximately 15,000adolescents, includinga wide sample of Minnesota children fromboth urban and rural settings. In addition to the MMPI, the subjects school recordswere obtained, and teacherswere asked to indicate which students theyfelt weremostlikely either to have psychiatric or legal difficulties. Hathaway and Monachesi alsogathered information concerning test scores on such instruments as intelligence testsand the Strong VocationalInterest Blank. The MMPI was then repeated on a sampleof 3,976 of these children when they reached 12th grade during the 1956-1957 schoolyear.Follow-up data were obtained by field-workers in the childrens community area,who searched files of public agencies, including police and court records. The au-thors continued to acquire biographical information on members of this sample untilthe mid-1960s (e.g., Hathaway, Reynolds, &Monachesi, 1969), and other researchersare currently performing follow-up studies on various subsections of the sample(e.g., Hanson et al., 1990). A summary of the early findings from this investiga-tion was published in a 1963 book by Hathaway and Monachesientitled Adolescent
  • 45. DEVELOPMENT OF THE MMPI AND THE MMPI-A 31Personality and Behavior: MMPI Patterns of Normal, Delinquent, Dropout, and OtherOutcomes.Hathaway and Monachesi (1953,1961,1963) undertook the collection of this mas-sive data set in order to implement a longitudinal/prospective study that wouldidentify personality variables related to the onset of delinquency. Rather than retroac-tively identifying a group of delinquent adolescents based on psychosocial histories,they chose to follow adolescents longitudinally to predict involvement in antisocialor delinquent behaviors. Thus, Hathaway and Monachesi hoped to identify MMPIpredictors that could serve as indicators of risk factors associated with the later devel-opment of delinquent behaviors.Monachesiand Hathaway (1969) summarized theirresults as follows:Scales4,8, and 9,the excitatoryscales, werefound tobe associated with high delinquencyrates. When profiles were deviant on these scales, singly or in combination, delinquencyrates were considerably larger than the overall rate. Thus, it was found that boys withthe excitatoryMMPI scale codes (where scales 4, 8, and 9 in combination were the mostdeviant scales in the profile) had a delinquency rate of41.9% in contrast to the overall rateof 34.6%. Again, scales 0,2,and 5 are the suppressor scales and were the dominant scalesin the profiles of boys with low delinquency rates (27.1% as against 34.6%). The variablescales 1,3,6, and 7were again found to have little relationship with delinquency.Ofgreatinterest is the fact that some of these relationships are even more marked for girls. In thiscase, the MMPI data are so closely related to delinquency that it was found that girlswith the excitatory code profile had a delinquency rate twice as large as the overall rate.Again, the more deviant scores on scales 4,8,and 9,the higher the delinquency rate.Girlswith inhibitor or suppressor scale scores have lower delinquency rates than the overallrate. (p. 217)Systematic follow-up and extensions of this work, usually based on further anal-yses of the Minnesota statewide sample, have provided relatively consistent supportfor the concept that elevations on scales Pd, Sc, and Ma serve an excitatory function.Higher scores on these scales are predictive of higher rates of "acting out" or delin-quent behavior in adolescent samples (e.g., Briggs, Wirt, & Johnson, 1961; Rempel,1958; Wirt & Briggs, 1959). Findings by Briggs et al. indicated that the accuracy ofprediction of delinquent behaviors increased when MMPI data were combined withdata regarding the family history of severe disease or death. Specifically,Briggs et al.found that when elevations on excitatoryscales were combined with positive historiesfor family trauma, the frequency of delinquent behavior was twice that of the gen-eral population. Similarly, Rempel reported that he could accurately identify 69.5%of a delinquent sample based on analysis of MMPI scales. When MMPI data werecombined with school record data in a linear regression procedure, the accurateiden-tification rate for delinquent boys rose to 74.2%.Morerecently,Huesmann, Lefkowitz,and Eron (1978) found that a simple linear summation of the sums of scales Pd, Ma,and Fserved as the best predictor of delinquent and aggressive behavior in a sampleof 426nineteen-year-old adolescents. This procedure was effective in predicting con-current incidents of aggression and delinquency as well as retroactively accountingfor significant proportions of variance in the ratings of aggressiveness for subjects atage 9.The research by Hathaway and Monachesi has proved to be very valuable in sev-eral ways. First, this researchestablished that the MMPIcould usefullypredict at leastone broad area of importantbehavior displayed by adolescents: delinquency.Second,their investigation provided a body of crucial informationconcerning differences in
  • 46. 32 CHAPTER 2item endorsement for male versus female adolescents and for adolescents versusadults, and it also identifiedimportant longitudinaltest-retest differences in item en-dorsement patterns occurring between middle and late adolescence. Third, the datacollected by Hathaway and Monachesi provided a major component of the tradi-tionally used adolescent norms later developed by Marks and Briggs (1972) and alsoserved as the exclusivedata source for another set of adolescent norms developed byGottesman, Hanson, Kroeker,and Briggs(published in Archer,1987b).Further,Hath-away and Monachesi empirically established the clinical correlates of high and lowscores for each of the 10 standard clinical scales separately for each gender. Finally,this project has provided an extraordinarily rich source of data for follow-upinvesti-gations of the original Hathaway and Monachesi subjects, spanning topics from theprediction ofjuvenile delinquency to the personality precursors ofschizophrenia (e.g.,Hanson et al., 1990).Development of Adolescent Norms and Codetype CorrelatesThe most frequently used adolescent norms for the original MMPI form were de-rived by Marks and Briggs in 1967 and first published in Dahlstrom et al. (1972,pp. 388-399). These norms have also been published in several other texts, includingMarks, Seeman, and Haller (1974,pp. 155-162) and Archer (1987b, pp. 197-213; 1997a,pp. 343-360). The Marks and Briggs adolescent norms were based on the responsesof approximately 1,800 normal adolescents, and were reported separately for malesand females at ages 17,16,and 15and also at age 14and below. The sample sizes usedto create these norms ranged from 166males and 139females at age 17to 271 malesand 280females at age 14and below.TheMarksand Briggsadolescent norms were based on responsesof720adolescentsselected from the data collected by Hathaway and Monachesi (1963)in the Minnesotastatewide sample combined with additional data from 1,046 adolescents collectedduring 1964 and 1965 in six states: Alabama, California, Kansas, Missouri, NorthCarolina, and Ohio. Marks et al. (1974) reported that this sample consisted of Whiteadolescents who were not receiving treatment for emotional disturbanceat the timeof their MMPI evaluation. Much of the research performed on the use of the MMPIwith adolescent populations has been based on the Marks and Briggs normativeset.Like the originalMinnesotaadultnorms,the norms developed by MarksandBriggsconverted raw scores to T-scoresusing the standard linear transformation procedure.T-scores were therefore determined by taking the nearest integer value of Tthroughthe use of the following formula:In this formula, M and SD represent the mean and standard deviation of the rawscores for a particular scale based on the normative distribution of subjects in theappropriate age category and gender, and Xi is equal to the raw score value earnedby a particular subject. Likethe Minnesota adult sample norms, the adolescent normswere based on data from White respondents.There were several distinguishing features of the adolescent norms developed byMarks and Briggs (1972).First, Marks and Briggs did not develop a K-correctionpro-cedure for use with their adolescent norms. Marks et al. (1974) listed several reasonsfor this decision. They noted that the original K weights were developed on a small
  • 47. DEVELOPMENT OF THE MMPI AND THE MMPI-A 33sample of adults and that their applicability and generalizability to adolescents wasquestionable. Further, they cited research findings indicating that K-correction pro-cedures with adolescents reduced rather than increased the relationships to externalcriteria. Second, the normativedata reported by Marksand Briggsincluded the scoresfrom all respondents, without screening out subjectsbased on validity criteriarelatedto scores on L,F,or K.Thus, all profiles were utilized in this data set, regardless of va-lidity scale values. The most extensive description ofthe adolescent norms developedby Marks and Briggs is provided in the Marks et al. (1974) text entitled TheActuarialUse of the MMPI With Adolescents and Adults.In addition to adolescentnorms,the Markset al. (1974) textalso containedactuarial-based personality descriptors for a series of 29MMPIhigh-point codetypes. The mainsubject pool utilized by Marks and his colleagues to derive these codetype descriptorscomprised 834 adolescents between the ages of 12 and 18. These adolescents wereevaluated after receiving at least 10hours of psychotherapy between 1965 and 1970.Theyweredescribed asWhiteteenagerswho werenot "mentally deficient or retarded"(p. 138). Marks et al. also reported that they later added an additional sample of419adolescents who received psychiatric services in the years 1970to 1973.Adolescentsin their samples completed the MMPIand a personal data form that included a self-description adjectivechecklist and questions covering such topics as attitudes towardself, attitudes toward others, motivational needs, and areas of conflict. The studyalso employed 172therapists from 30states, who provided descriptive ratings on theadolescents. Accordingto Markset al.:Of the 172 psychotherapists who provided patient ratings, 116 were either Boardcertifiedpsychiatrists, Ph.D. level clinicalpsychologists, or M.S.W. level social workers with twoadditional yearsoftherapyexperience. These "experienced" therapists rated 746patientsor 90% of the cases; an additional 24 therapists who were either third- or fourth-yearclinical psychology interns, third-yearpsychiatricresidents, or recent M.S.W. graduatesrated 83 patients or 10%of the cases, (p. 139)Clinician ratings involved multiple instruments, including a case data schedule, anadjective checklist, and a Q-sort of personality descriptors. Therapists ratings werebased on available evidence, including case records, chart notes, and psychologicaltest findings, excluding MMPI results.Taken together, the preliminary codetype pool available to Marks et al. consistedof 2,302 descriptors that were potentially relevant to adolescents experiences. Theauthors then selected from these potential correlates or descriptors 1,265 descriptorsthat were deemed to be relevant for both male and female respondents, that occurredwith sufficient frequency to allow for statisticalanalyses, and that offered informationthat was clinically relevantin terms ofpatient description. Datafrom adolescentswerethen grouped into descriptive categories related to 29high-point codetypes, with anaverage sample size of 13.4 respondents per codetype. Descriptors were developedthat differentiated between high and lowprofiles (profiles above and below the mediantwo-point codetype elevation for that grouping, respectively) as well as between two-point code reversals (e.g., 2-4 in contrast to 4-2 codes). A detailed discussion of thecodetype procedures used in this correlate study is presented in Marks et al. (1974)and in Archer (1987b).The Marks et al. (1974) clinical correlate study was crucial in providing clini-cians with the first correlate information necessary to interpret adolescents code-type patterns. Further, the information provided by Marks et al. was sufficiently
  • 48. 34 CHAPTER 2comprehensive and sufficiently flexible in terms of application that their system wascapable of classifying a large proportion of adolescent profiles typically obtained inclinical settings. The Marks et al. actuarial data descriptions for adolescents repre-sented a substantial improvement over the Hathaway and Monachesi (1961) text, AnAtlasof Juvenile MMPI Profiles, which was composed of 1,088 MMPIcodes representingindividual profile configurations from their sample of Minnesota ninth graders. Eachprofile was accompanied by a short case history and a brief description of that sub-jects most salient personality features. A clinician using this atlas identified the caseswith profiles most similar to the one produced by his or her patient and then read theaccompanying case descriptions. The clinician had to derive his or her own summaryof personality features commonly found for the codetype without the assistance ofstatistical evaluations to identify the most relevant descriptors for the codetype ingeneral.More Recent Contributions (1975-1991)Since the publication of the textby Marks et al. (1974), substantial work has been donein applying the MMPI to adolescents. This work was summarized by Archer (1984,1987b), Butcher and Williams (2000), Archer and Krishnamurthy (2002), and Colli-gan and Offord (1989). Specifically, Archer reviewed the numerous studies indicatingthat adolescent response patterns should be evaluated exclusively with reference toadolescent norms and not with reference to the adult norms. Colligan and Offord(1989) noted research done with adolescent samples in the areas of medicalevalua-tion, school adjustment, and juvenile delinquency. Of particular interest is the worksubsequent to Marks et al. (1974) in the areas of adolescent norm development andclinical correlates.In addition to the adolescent norms developed by Marks and Briggs (1972), adoles-cent MMPInorms for the traditional MMPIinstrument were developed by Gottesmanet al. 1987 (published in Archer, 1987b) and by Colligan and Offord (1989)at the MayoClinic. The norms developed by Gottesman and his colleagues represent a compre-hensive analysis of the approximately 15,000 ninth-grade adolescents tested between1948 and 1954 and the approximately 3,500 12th graders tested during 1956 and 1957by Hathaway and Monachesi intheir statewide sample. Sample size, validity criterion,raw score, and T-score data for this project are reported in Archer (1987b)in AppendixC. In addition to standard scale data, Gottesman et al. provided T-score conversionsfor a variety of MMPI special scales, including Barrons (1953) Ego Strength scale,MacAndrews (1965)Alcoholism scale, Welshs (1956)Anxietyand Repression scales,the Wiggins (1969) Content scales, and the special scales developed by Rosen (1962)for differential diagnosis of psychiatric patients.Colligan and Offord (1989) also collected normative data for the original versionof the MMPI based on the responses of 691 girls and 624boys between the ages of 13and 17, inclusive. In collecting these data during the mid-1980s, the authors randomlysampled from 11,930 households in Minnesota,Iowa, and Wisconsinthatwere withina50-mile radius ofthe MayoClinic, which islocated in Rochester,Minnesota.Telephoneinterviews established that slightly more than 10% of these households containedadolescents within the appropriate age groups, and after excluding adolescents withpotentially handicapping disabilities, 1,412 adolescents were targeted forevaluation.MMPI materials were then mailed to these households, resulting in return rates of83% for female adolescents and 72%for male adolescents. Colligan and Offord foundlittle evidence of significant differences in mean raw score values across age groups,
  • 49. DEVELOPMENT OF THE MMPIAND THE MMPI-A 35and therefore the final norms are based on normalized T-score conversions for 13-through 17-year-olds, with conversions presented separately by gender. Colligan andOfford (1991) also recently provided K-corrected T-score values for these norms.Both the Gottesman, Hanson, Kroeker, and Briggs (1987) and the Colligan andOfford (1989) adolescent norm projects have substantial strengths. Although theGottesman et al. data are based on MMPI responses of adolescents tested nearly40years ago, their current analyses are the first to comprehensively evaluate this verylarge and important data set. Additionally, the Marks and Briggs (1972) norms andthe Gottesman et al. (1987) norms share common subjects and produce T-scorecon-version values for the standard MMPI scales that are similar. The Gottesman et al.MMPI special scale T-score values are, therefore, probably relatively close to thosethat would have been provided by Marks and Briggs had they attempted to derivenormative data for MMPI special scales. The work of Colligan and Offord is basedon a solid methodology employed with a contemporary sample of adolescents andtherefore provides very useful data concerninghow modern teenagers respond to theoriginal version of the MMPI.A complete evaluation ofboth of these adolescent normsets, however, would require several years of investigation.Preliminary studies by Archer, Pancoast, and Klinefelter (1989) and Klinefelter,Pancoast, Archer, and Pruitt (1990) examined the degree to which the Gottesmanet al. (1987)and Colligan and Offord (1989) norm sets produce profile elevations andconfigurations that differ from those produced by the traditional Marks and Briggs(1972) norms. These studies employed samples of normal, outpatient, and inpatientadolescents scored on allthree normativesets. Resultsindicated significant differencesin profile elevation by norm set, with the lowest T-score values typically producedby the Colligan and Offord norms. Using standardized criteria to judge profile con-gruence, the congruence rates ranged from 53%for profiles generated by Marks andBriggs versus Colligan and Offord to approximately 60%for profiles scored on theMarks and Briggs and Gottesman et al. norms. These data suggest that the more re-cent norms generate codetypes that may often differ from those generated by thetraditional Marks and Briggs norms. Therefore, the existing codetype literature re-lated to the traditional version of the MMPI may not apply to all profiles gener-ated by these recently published adolescent norms. Given this observation, it seemsmost reasonable to apply Gottesman et al. or Colligan and Offord norms in con-junction with the traditional Marks and Briggs norms on the original version of theMMPI rather than employing either of these as a substitute for the Marks and Briggsnorms.In addition to the work that has been done on adolescent normative values, sev-eral investigations have examined the clinical correlatesof single-scale and two-pointcodetypes based on the traditional Marks and Briggsadolescent norms. Archer, Gor-don, Giannetti, and Singles (1988), for example, examined descriptive correlates ofsingle-scale high-point elevations for scales 2,3,4,8, and 9in asample of112adolescentinpatients. Clinical descriptors were collected for subjectsbased on their psychometricself-reports and patient ratingsby parents, nursing staff, and individual psychothera-pists. Ingeneral, findings from this study produced correlatepatterns thatwere highlysimilar to those reported for basic MMPI scales in the adult literature. Using a sim-ilar methodology, Archer, Gordon, Anderson, and Giannetti (1989) investigated theclinical correlates of the MacAndrew Alcoholism scale, Welshs Anxiety and Repres-sion scales, and Barrons Ego Strength scale in a sample of 68 adolescent inpatients.Results from this study also indicated patterns of clinically relevant descriptors thatwere largely consistent with findingsderived from studies of adult respondents. Ball,
  • 50. 36 CHAPTER 2Archer, Struve, Hunter, and Gordon (1987) found evidence of subtle but detectableneurological differencesbetween adolescent psychiatric inpatients with and withoutelevated scale 1values. Further, Archer and Gordon (1988)found that scale 8 elevationwas an effective and sensitive indicator of the presence of schizophrenic diagnoses ina sample of adolescent inpatients.Williams and Butcher (1989a) also examined single-scale correlates in a sample of492 boys and 352 girls primarily evaluated in either substance abuse or psychiatricinpatient units.Standard scalevalues wereinvestigated in relationship todata derivedfrom psychiatric records and parental and treatment staff ratings and reports. SimilartoArcheret al.(1988),the authors concluded thatthe single-scale descriptorsfound forthese adolescents were consistent with those reported in adult studies. Additionally,Williams and Butcher (1989b)investigated codetype correlates for this sample of844adolescents and found that although some of the codetype descriptors reported byMarks et al. (1974) were replicated in this study, other descriptor patterns were notsupported. Studies by Lachar and Wrobel (1990) and by Wrobel and Lachar (1992)examined the issue of gender differences in correlate patterns and found evidenceof substantially different correlate patterns for male and female adolescents. Theirfindings underscore the need for more emphasis to be placed on the issue of potentialgender differences in MMPI clinical correlate studies of adolescents.Several researchers have also examined the effects of using both adolescent andadult norms in terms of profile elevation and configuration.Specifically, studies byArcher (1984), Ehrenworth and Archer (1985), Klinge, Lachar, Grissell, and Berman(1978),Klingeand Strauss (1976),and Lachar,Klinge,and Grissell (1976) examined theeffects of using adolescent and adult norms in profiling responses of maleand femaleadolescents admitted to inpatientpsychiatricservices.Thesestudieshave consistentlyshown thatthe degree ofpsychopathology displayed by adolescentrespondentstendsto be more pronounced when adult norms are employed, particularlyon scales F,4,and 8. Finally, factor analytic studies have been reported based on scale-level data(Archer, 1984) and on both item- and scale-level data (Archer & Klinefelter,1991).In general, the results of these studies produced factor patterns that are reasonablyconsistent with those that have been typically derived from factor analyticfindingsin adult samples.Frequency of Use of the MMPI in Adolescent AssessmentsAs we have seen, research attention has been increasingly focused on the use ofthe MMPI in adolescent populations. Until the early 1990s, however, no surveysof test usage were specifically targeted at practitioners working mainly with ado-lescents. Therefore,the relative popularity of instruments such as the MMPIamongsuch practitioners remained unclear.In addressing this issue, Archer,Maruish,Imhof,and Piotrowski (1991) asked psychologists how frequently they used each of 67 in-struments in their assessment of adolescent clients. The results for the these assess-ment instruments were evaluated based on total number of "mentions" as well astabulated with adjustments for frequency of test usage. The MMPI was the thirdmost frequently mentioned assessment instrument for evaluating adolescents (be-hind the Wechsler scales and the Rorschach)and the sixth most frequently employedinstrument when scores were adjusted for frequency of use (following the Wechsler,Rorschach, Bender-Gestalt, TAT, and Sentence Completion instruments). TheMMPIwas the most frequently employed objective personality assessment instrument forevaluating teenagers when either total mentions or weighted scores werecalculated.

Asshown in Fig.2.1, the WechslerIQmeasures and theRorschach werethe most frequently reported tests included within standardbatteries.The MMPIranked fifth and was included by roughly half of the survey respondents.In contrast, the only other objective personality assessment instrument included inFig. 2.1 is the Millon Adolescent Personality Inventory (Millon, Green, &Meagher,1977), which was included in only 17% of the standard test batteries reported bythe respondents. Overall, the results of the survey by Archer, Maruish, et al. (1991)indicated that the MMPI,consistent with surveys oftest use in adult populations (e.g.,Lubin et al., 1985), was the most frequently used objective personality assessmentinstrument in evaluations of adolescents.DEVELOPMENT OF THE MMPI-ADespite the popularity of the MMPI,researchers and clinicians have expressed con-cerns regarding several aspects of the use of the MMPIto assess teenagers. For exam-ple, Archer,Maruish, et al. (1991) asked survey respondents to indicate their percep-tions ofthe major advantagesand disadvantages ofusing the MMPI with adolescents.Major advantages reported included the comprehensive and accuratenature of clin-ically relevant descriptors, the relative ease of administration and scoring, and theextensive adolescent research database available for this instrument. Forty-nine per-cent of respondents, however, indicated that they felt the test was too long, 20%ofrespondents had concerns regarding inadequate or outdated adolescent norms,18%felt that the reading level of the original MMPIwas too high, and 17% objected to theuse of inappropriate or outdated language in the item pool. Consistent with mostofthe survey respondents views, Table 2.2 summarizes a variety of factors pointing tothe need for revision of the original test instrument.Serious concernshavebeen expressed regarding the nature ofthe adolescent normsavailable for the original MMPI.Specifically,the Marks and Briggs (1972) adolescent

This adolescent data set is therefore substantially dated anddramatically limited in terms of ethnic representation. Pancoast and Archer (1988)examined the adequacy of the traditional adolescent norms in an analysis of normaladolescent samples collected between 1947 and 1965 and normal adolescent samplescollected in the decade following 1975. Findings supported the adequacy of the tra-ditional adolescent norms for evaluations of samples of normal adolescents collectedbetween 1947 and 1965. This interval of time coincides with the data collection pe-riod for the adolescent samples used in the Marks and Briggs (1972) norms. MMPIpatterns produced by more contemporary samples of adolescents, however, were ele-vated above the Marksand Briggsmean values on most clinical scales. These findingssuggest that the traditionaladolescent norms may not provide an accuratenormativebaseline, in terms of mean fit,for evaluations of contemporary adolescents.Also, some of the item content of the original MMPI has been criticized as inap-propriate for the assessment of teenagers. Most clinicians who have used the originalversion with teenagers have probably been aware that an item concerning "drop thehandkerchief" has little meaning for todays adolescents and that questions concern-ing "deportment" are not readily understood by many adolescents. Similarly, state-ments such as "my sexlife is satisfactory" may have a substantially different meaningwhen asked of a 13-year-old and a 30-year-old. Further, awkwardly worded items,a source of concern in administration of the MMPI to adults, was a major problemin the assessment of adolescents. Finally, the MMPI item pool, although quite ex-tensive, has historically lacked items of specific relevance to adolescent experiences,including problem areas that typically emerge during the teenage years, such as druguse, eating disorders, and school-related problems. In addition to modifications at theitem level, the creation of MMPI items related to adolescence provided an opportu-nity to develop scale measures of specific relevance to adolescent development andpsychopathology. Although several special MMPI scales developed for adults hadbeen applied to adolescents (e.g., the Welsh Anxiety and Repression scales and theMacAndrew Alcoholism scale), these scales were not specifically developed for thispopulation.
  • 53. DEVELOPMENT OF THE MMPI AND THE MMPI-A 39On July 1,1989, the MMPI Adolescent Project Committee, consisting of James N.Butcher, Auke Tellegen, and Robert P. Archer, was appointed by Beverly Kaemmerof the University of Minnesota Press to consider the advisability of creating an ado-lescent version of the MMPI and the features such a version should incorporate ifdevelopment was undertaken.Goals of the MMPI-A ProjectA number of goals were envisioned in the creation of the MMPI-A. Some of thesegoals were in conflict and required varying degrees of compromise for work to moveforward on the adolescentversion.Itwas clearthat adult norms would not be applica-ble to an adolescentversion (Archer, 1984,1987b, 1990;Williams,Graham, & Butcher,1986) and that a national normative sample representative of the general populationof U.S.teenagers would be required for the MMPI-A. An emphasis was also placed onshortening the length of the MMPI, to the extent that this could be achieved withoutloss of substantive clinicalinformation. Maintainingcontinuity between the originalMMPI and the MMPI-Awas also stressed, including preservation of the standard orbasic MMPI validity and clinical scales. Within this context, however, opportunitieswere taken to improve MMPI scales F, M/, and Si based on observations concern-ing adolescent response characteristics on these measures in the MMPI-A normativesample. If a version of the MMPI was to be developed for adolescent assessment, itwas also deemed desirable to include items and scales directly relevant to adoles-cent development and expression of psychopathology.Finally,it was anticipated thatthe release of an adolescent version would help to standardize assessment practiceswith adolescents. As noted by Archer (1984,1987b), there has been considerable con-troversy and confusion regarding the optimal approach to interpreting adolescentsMMPI profiles. Questions concerning the most appropriate administration criteria,norm sets, special scales, and clinical correlates have been the subject of substantialdebate, without clear and consistent resolution. The development and release of theMMPI-A and the extensive manual for this instrument (Butcher et al., 1992) served tostandardize and improve assessment practices for both clinician and researcher.The Experimental Booklet (Form TX)The development of the MMPI-A was initiated with the creation of an experimen-tal test booklet for adolescents, identified as MMPI Form TX.This experimental testbooklet contained 704 items to be used in normative data collection efforts and inpreliminary analyses to determine the feasibility of creating an adolescent form. Thefirst section of this booklet contained 550 items from the traditional MMPI form; itwas followed by a new experimental item pool for which scale membership andclinical correlates had not yet been established. The 154 items included in the sec-ond section involved content areas such as negative peer group influence, alcoholand drug abuse, family relationship difficulties, school and achievement problems,eating disorders, and identity problems (Archer, 1987b). Of the original 550 items,approximately 13%had been reworded to increase content clarity or quality. The 16repeated items in the traditional MMPI version were eliminated from MMPIFormTX. In addition to MMPIFormTX,adolescents in the normative samples were admin-istered a 16-item Biographical Information Form and a 74-item Life Events Form. Thebiographical questionnaire obtained data on anumber ofvariables, including age, eth-nic background, family structure,parental education and occupation, and academic

The life events questionnaire requested information on the occurrenceand effect of life events such as major illnesses, loss of family members, and parentalseparation or divorce.The MMPI-ANormative SampleThe collection of adolescent normative data was undertaken in eight states, sevenof which also served as primary sites for adult normative data collection for theMMPI-2. Adolescent normative subjects were generally solicited by mail from therosters of junior and senior high schools in predetermined areas, and subjects weretested in group sessions generally conducted within school settings. Adolescents whoparticipated in the MMPI-A normative data collection were paid for their voluntaryparticipation. A total of approximately 2,500 adolescents were evaluated using theMMPI Form TX in data collection efforts in Minnesota, Ohio, California, Virginia,Pennsylvania, New York, North Carolina, and Washington. Various exclusion criteriawere applied to these data, including the following: (a) subjects with incompletedata; (b) Carelessness scale values > 35; (c) original F scale value > 25; (d) subjectage < 14 or > 18. Employing these exclusion criteria resulted in the creation of afinal adolescent normative sample that included 805males and 815females. Table 2.3shows the geographic distribution of this adolescent sample, and Table 2.4 providesTABLE 2.4Age Distribution of Adolescents in the MMPI-ANormative SampleAge1415161718Males (N =Frequency19320722813542805;%24.025.728.316.85.2Females (NFrequency17423120216345= 815;%21.328.324.820.05.5Note.

The mean age of male adolescents in the MMPI-A normativesample was 15.5 years (SD = 1.17 years), and the mean age for females was 15.6years(SD = 1.18 years).Table 2.5 provides information concerning the ethnic origins of adolescents in theMMPI-A normative sample. Theethnic distribution ofthe MMPI-Anormative samplerepresents a reasonable match against U.S. Census figures, with approximately 76%of the data derived from Whites, 12%from Blacks, and the remaining 12%from otherethnic groups.Tables 2.6 and 2.7 provide data on fathers and mothers educational levels, re-spectively, for adolescents in the MMPI-A normative sample. In general, these datashow that the parents of adolescents used in the MMPI-A normative sample are welleducated and that higher educational levels are overrepresented in comparison to the1980 U.S.Census data. Specifically, roughly 50%of the fathers and 40%of the mothersof children in the MMPI-Anormative sample reported achieving a bachelors degreeor attaininga higher educationallevel, whereas only 20%of males and 13%of femalesin the 1980 U.S. Census data reported comparable educational achievement. This de-gree of overrepresentation ofbetter educated individuals is very similar to that foundin the MMPI-2 adult normative sample (Archer,1997a). This phenomenon is proba-bly related to the use of volunteer subjects in normative data collection procedures,in which better educated and higher socioeconomic status subjects are differentiallymore likely to participate.

Table 2.11 provides an overview of the scale structureofthe MMPI-A.The new validity measures for the MMPI-Ainclude the FI and F2 sub-scales of the standard F scale as well as the TrueResponse Inconsistencyscale (TRIM)and the Variable Response Inconsistency scale (VRIN) developed by Auke Tellegen.The supplementary scales for the MMPI-Ainvolve measures that were developed forthe original MMPI, including the Anxiety (A) scale, the Repression (R) scale, and theMacAndrew Alcoholism scale (MAC). In addition, the supplementary scalesincludea variety of new measures developed for the MMPI-A, including the Immaturity(IMM) scale, the Alcohol/Drug Problem Acknowledgment (ACK) scale, and the Al-cohol/Drug Problem Proneness (PRO) scale. Most of the 15contentscales developedfor the MMPI-A overlap with similar measures developed for the MMPI-2, but sev-eral of these scales were created specifically and uniquely for the adolescent version.The Harris-Lingoes content subscales developed for the original MMPIversion werecarried over to the MMPI-A, with a few item deletions resulting from the deletionof items on the basic scales. The Si subscales were directly carried over from theircounterparts in the MMPI-2.The MMPI-A manual by Butcher et al. (1992) containsa listing of MMPI-A items accompanied by data concerning endorsement frequen-cies and reading requirements. Appendix Bprovides the composition of each of theMMPI-A basic scales, content and supplementary scales, and Harris-Lingoes and Sisubscales. Finally, Butcher et al. (1992)showed item number conversion informationfor the group form of the original MMPI and MMPI-A and for conversions betweenitems in the MMPI-2 and MMPI-A.MMPI-A Normative Sample:ComparisonsWith Earlier Normative GroupsNewsom, Archer, Trumbetta, and Gottesman (2003)examined the changes in adoles-cent self-presentation on the MMPI and MMPI-A over a 40-year period. The primarysamples used by these researchers for comparison included 1,235 adolescents betweenthe ages of 14and 16who were in the MMPI-Anormative sample for which data wascollected in 1989and 10,514 adolescents between the ages of 14and 16for which datawas collected between 1948 and 1954 in the Hathaway and Monachesi (1963) studyof adolescent personality and behavior. MMPI basic scale and item-level data werealso included for 817 adolescents, aged 14 through 16,used by Colligan and Offord(1992) in their 1985 study of the original form of the MMPI.Overall, the result of theseevaluations revealed that adolescents from the MMPI-A normative sample scoredsignificantly higher across the basic clinical scales and lower on validity scales L andK than did adolescents from the Hathaway and Monachesi (1963) sample. The MMPIbasic scale mean data reported by Colligan and Offord typically fell in a midrangebetween these two. Results were interpreted as reflecting moderate to large changesin response frequencies between eras of data collection, with evidence of a relativelyhigher frequency of item endorsement by contemporary adolescents in the clinicaldirection on most MMPIbasic clinical scales, particularly scales Ma, Sc,and Hs. Thus,contemporary normal adolescents not only endorse more psychopathological symp-toms than do adults but also endorse more pathology than did adolescents evaluated40years agoin the Monachesi and Hathaway sample. Aswe will explorein more detaillater, these response patterns may indicatethatnormaladolescents experience enoughpsychological turmoil and distress to render accurate discrimination between nor-mal and abnormal functioning particularly difficult during this developmental age.

The implications of these findingsforclinical applications of the MMPI-A are discussed in detail in Chapter 6.Clinical Popularity of the MMPI-AAs previously noted, Archer, Maruish, et al. (1991) presented survey findings on thepopularity ofthe MMPIamong psychologists who perform psychological assessmentswith adolescent clients. Archer and Newsom (2000) designed an investigation to up-date these results by examining the test use practices reported by 346psychologistswho work with adolescents in a variety of clinical and academic settings. These re-spondents had an adjusted survey return rate of 36%and predominantlyconsistedofdoctoral prepared psychologists (95%) in private practice settings (51%). The surveyrespondents had a mean of 13.6 years of postdegree clinicalexperience and spent anaverage of 45%of their clinicaltime working with adolescents.Table 2.12presents theTABLE 2.12Test Usage Ratings for the Ten Most Widely Used Assessment Instruments WithAdolescentsUsage Rating TotalsInstrument a b c d e f TM WSWechsler Intelligence ScalesRorschach Inkblot TechniqueSentence Completion Tasks (any form)Thematic Apperception TestMMPI-AChild Behavior Checklist,Parent Report FormThe House-Tree-Person TechniqueWide Range Achievement Test(any format)Child Behavior Checklist,Teachers Report FormConners Rating Scales-Revised8210810911412813313915413813523463146456252445446374857555550635065822722323825181826252763384933393023312931101715547414138282212251225224219205201194179195198935715712637591541514486485475Note, a = never; b = infrequently; c = occasionally; d = about 50%of the time; e = frequently; f =almost always; TM = total mentions; WS = weighted score (sum of n x numericalweight of ratings;a = 0,b - 1,c = 2,d = 3,e = 4,f = 5).From Archer and Newsom (2000).

As shown in thetable, these include the WechslerIntelligence Scales, several projectives, oneobjectiveself-report measure(MMPI-A), and Parentand TeacherBehavioral RatingForms. TheMMPI-A was ranked fifth in both total mentions by respondents in the survey and bya score weighted by frequency of use. Further, the MMPI-A was the only self-reportobjective personality assessment instrument included in these top ten instruments.In general, there is a considerable degree of similarity between the findings of the1991 survey by Archer et al. and the Archer and Newsom (2000) results. For exam-ple, the WechslerIntelligenceScales, the Rorschach,the TAT, and the MMPI remainamong the most widely used tests with adolescents. In addition to questions relatedto test utilization, Archer and Newsom requested respondents to indicate the pri-mary strengths associatedwith the use of the MMPI-A. The responses were, inorder,the MMPI-As ability to provide a comprehensive clinical picture, the availabilityofcontemporary adolescent norms,the instruments easeofadministration and psycho-metric soundness, and the comprehensivenessof the researchbase availablefor theinstrument. Themost frequentlycited disadvantages reported by the respondents in-cluded (in order)the length of test instrument and associated demands forprolongedcooperation, a reading level that is too demanding or difficult for manyadolescents,time requirements for scoring and interpretation, time requirements related to theadministration of the test, and, finally, the expense associated with purchasing andusing the test instrument in a managed care environment.Overall, Archerand New-som observed that the MMPI-Ahas attained the status achieved by its predecessor,quickly becoming the objective personality assessment instrument mostcommonlyused to evaluate adolescents.Research Popularity of the MMPI-AIn 1987, Archer noted that there were roughly 100studies reporting on the originalversion of the MMPI in adolescent populations from its release in 1943 to the mid-1980s. Forbey (2003) recently reviewed the literature on the MMPI-Aand identifiedapproximately 112 books, chapters, and researcharticles published on this instrumentsince its release in 1992. As a point of further comparison, Forbey noted that only 15works on the Millon Adolescent Clinical Inventory (MACI) have been published inthe same 10-year period, and 781published articles on or descriptions of theMMPI-2.Forbey observedthatthe content areasaddressed inthe developing MMPI-Aliteraturehave been fairly broad, and he grouped these publications into several not mutuallyexclusive categories. The publications included 6 studies on the use of the MMPI-A as an externalcriterion in validation of other instruments; 2 studies in which theMMPI-A had been used to address forensicor child custody issues; 14 investigationsin which the MMPI-Aaddressed cross-cultural or multicultural issues; 9 books andbook chapters serving as instructionalguides to the MMPI-A; 22articlesrelated to theuse ofthe MMPI-A with specific populations, such as juvenileoffenders, academicallygifted adolescents, or eating disordered adolescents; 25articles dealing with specificmethodological issues, such as the factor structureof the test instrument,normativesamples, or reliability issues; and 21 articles related to the development of specificscales or groups of scales, such as the Immaturity (IMM) supplementary scales orthe MMPI-Acontent scales. Finally,Forbey reported an additional group of studiesfocused on methodologicalissues, the largest subcomponent of which comprises 10studies specifically investigating the MMPI-Avalidity scales. Forbey concluded that
  • 62. 48 CHAPTER 2research with the MMPI-A is progressing at a much faster pace than research onadolescence done with the original version of the MMPI.SUMMARYThe MMPI-A is closely related to both the original version of the MMPI and theMMPI-2. The MMPI-A,however, also contains features that are unique to it. Muchof the research on adolescence done with the original version of the MMPI appearsgeneralizable to the MMPI-A.It also seems that much of the research currently beinggenerated using the MMPI-2 (e.g., validation of MMPI-2 content scales and studiesfocused on codetype congruence) has relevance for the use of the MMPI-A.The de-velopment of the MMPI-A, however, represents the first time in the roughly 50-yearhistory ofthis instrumentthat a specialized set of adolescent norms and a specific ado-lescent version have been released by the test publisher. The MMPI-A,therefore,hasthe potential to produce significant improvements in the assessment ofpsychopathol-ogy in adolescents by underscoring the unique aspects of MMPI interpretation neces-sary with this age group. The research by Archer and Newsom (2000) demonstratesthat the MMPI-A rapidly replaced the MMPI as the most widely used objective per-sonality assessment instrument for evaluating adolescents, and Forbeys 2003surveyindicates that research findings achieved with this new instrument are accumulatingquickly.
  • 63. 3Administration and Scoring IssuesQUALIFICATION AND BACKGROUND OF TEST USERSThe use of the MMPI-Awith adolescents requires specific training and experience inseveral areas.First,the clinicianshould be adequately trained in the essential featuresof test theory and test construction as well as specifically in the development anduses of the MMPI-A.Therefore, the test user should have completed graduate-levelcourses in psychologicaltesting and reviewed introductoryor basic texts, such as thetexts by Archer and Krishnamurthy (2002) and Butcher and Williams (2000). Thoseseeking greaterfamiliarity with the development ofthe originalMMPIor theMMPI-2,including the composition of the basic validity and clinical scales and the basic inter-pretive strategies, should refer to the general guides written by Friedman et al.(2001),Graham (1987, 2000), Greene (1980, 2000), and Nichols (2001). Reference works byArcher (1987b), Hathaway and Monachesi (1963), and Marks et al. (1974) concern theuse of the original MMPIin the assessment of adolescents. Before administering theMMPI-A, the clinician should also thoroughly review the MMPI-Amanual (Butcheret al., 1992),which provides a summary of the development, administration, scoring,and interpretation of this instrument.In addition to an understanding of psychological assessment issues, individualswho use the MMPI/MMPI-A in the evaluation of adolescents should have train-ing in adolescent development, personality, psychopathology, and psychodiagno-sis.Administration PersonnelBecause the actualadministration of the MMPI or MMPI-A appears deceptively sim-ple, it is frequently entrusted to individuals operating under the supervision of apsychologist. If these individuals are carefully trained, closely supervised, and wellinformed concerning appropriate test procedures, their administration of the testshould not negatively affect test validity. Unfortunately, there are many instancesof invalid MMPIfindings related to incorrect administration procedures used by un-trained or unsupervised clerks or secretaries. Greene (2000) noted that although aclinician may delegate the task of MMPI administration to an assistant, a clinician49
  • 64. 50 CHAPTER 3cannot delegate the responsibility for proper administration. This responsibility re-mains with the clinician utilizing and interpreting the test findings. Because testingconditions, test instructions, and response to clients questions about test materialsor purposes can all profoundly affect test results, the clinician must ensure that theaccepted standards for administration procedures are fully met.Purposes of MMPI-AAdministrationThe MMPI-A is designed to assess psychopathology among adolescents aged 14through 18 inclusive and may be selectively used with 12- and 13-year-old adoles-cents under certain circumstances, which are discussed later.As noted in theMMPI-Amanual (Butcher et al., 1992), 18-year-olds may be evaluated with this instrument ifthey are living with their parents in a dependent environment but should be assessedwith the adult form of the revised MMPI (i.e., the MMPI-2) if living independently.The MMPI-A is appropriate for evaluating adolescents who are experiencing, or maybe suspected of experiencing, some type of psychopathology. The MMPI-A has twomajor functions in the assessment of adolescent psychopathology. First, the MMPI-A provides the ability to objectively evaluate and describe an adolescents level offunctioning in relation to selected standardized dimensions of psychopathology. Aclinician may examine MMPI-A test findings, for example, in order to assess the de-gree to which an adolescents psychological functioning deviates from that typicallyreported by normal adolescents. For such a purpose, the clinician compares the ado-lescents test scores against those obtained from the MMPI-A normative sample. Ifthe adolescent exhibits clinical levels of psychopathology on the MMPI-A, the clini-cian may also consult the clinical literature on the MMPIand the MMPI-Ato find themost appropriate descriptors for that adolescent. These descriptors are establishedbased on research with adolescents who have produced similar MMPI-A patterns.Second, the repeated administration of the MMPI-A can provide the clinician witha means of assessing changes in psychopathology across time. The ability to assesstemporal changes is particularly important in dealing with adolescents because ado-lescence is defined by rapid changes in personality and psychopathology. When theMMPI-A is administered at various stages in the treatment process, test results mayalso provide the clinician with a sensitive index of therapeutic change. Because theMMPI-A was developed as a means of describing psychopathology, it was not in-tended to serve asa primary measure for describing normal-range personality traits orfunctioning.ADMINISTRATIONISSUESA number of administration guidelines or criteria may be offered for using theMMPI-A with adolescents. Table 3.1 provides an overview of these criteria, with suggestedresponses that may be utilized by the clinician in dealing with specific administrationissues and problems.Age CriteriaGeneral administration guidelines for the use of the original version of the MMPIwith adolescents were provided by Dahlstrom et al. (1972), Williams (1986), andArcher (1987b, 1989). Guidelines for the administration of the MMPI-A have been

Consider dividing testing into two or more sessions.provided more recently by Archer and Krishnamurthy (2002) and by Butcher andWilliams (2000). The test manual observes that the MMPI-A can be administeredto "bright immature adolescents" as young as age 12, and Archer and Krishna-murthy (2002) recommended that younger subjects (i.e., those aged 12 and 13) becarefully evaluated before MMPI-Aadministration is undertaken. In recognition ofthe difficulty that many 12-and 13-year-olds encounter in attempting to respond tothe MMPI-A,the MMPI-Anormative sample was restricted to 14-through 18-year-olds. If a 12- or 13-year-old meets all administration criteria, however, includingadequate reading ability and cognitive and social maturity,it is possible to admin-ister the MMPI-A to him or her. A set of MMPI-A adolescent norms for 13-year-old boys and girls, based on linear T-score conversions and using the same exclu-sion criteria employed for the 14-through 18-year-old MMPInorms (e.g., original Fscale raw score >25), was included in the prior editions of this text (Archer, 1992a,1997b).A study by Janus,de Grott, and Toepfer (1998)examined two questions concerningthe use of the MMPI-A with 13-year-old inpatients. These questions involved theextent to which the profilesof 13-year-old inpatients differed substantively from thoseproduced by 14-year-olds and the effects of scoring 13-year-olds using the standardMMPI-A normsversusthe MMPI-Anormsfor 13-year-olds reportedby Archer(1992a,1997b).Janusand his colleaguesanalyzed the protocolsfrom fifty-six 13-year-old andeighty-five 14-year-old psychiatric inpatients. Theyreported no significant differencesfor age in mean T-scores and no clear pattern of differences in the percentage ofelevated profiles. A strong multivariate effect was found, however, for the use of theArcher (1992a, 1997b) MMPI-A norms, which resulted in lower T-scorevalues thanthe use of the standard MMPI-A adolescent norms. However, pervasive univariatedifferences based on the use of 13-year-old versus standard adolescent norms werenot found, and statistically significant differences occurred for only 2 of 38 scales for
  • 66. 52 CHAPTER 3boys and 7 of 38 scales for girls. In general, the results of this study suggest that13-and 14-year-old adolescents respond in similar ways and that the use of a separateset of 13-year-old norms may not result in any tangible improvements in MMPI-Ainterpretation for this age group.It is cautioned, however, that 13-year-old adolescents typically represent an agegroup difficult to evaluate with the MMPI-A. All criteria for administration must becarefully assessed to determine if these younger adolescents are capable of produc-ing valid responses. Younger adolescents may not have a wide enough range of lifeexperiences, including exposure to cultural and educational opportunities commonlyencountered in U.S. society, to render the item content psychologically and seman-tically meaningful. Limitations in developmental opportunities as well as readingability clearly contraindicate the administration of the MMPIor MMPI-A to youngeradolescents.At the other end of the adolescent age range, the MMPI-2and MMPI-A normativesamples overlap at age 18, and it is possible that an 18-year-old respondent couldbe evaluated with either instrument. The MMPI-A manual contains the followingrecommendation concerning the evaluation of18-year-olds:The clinicians should make a case-by-case judgment about whether to use the MMPI-A or the MMPI-2 with 18-year-olds because the normative and clinical samples forboth tests include 18-year-olds. A suggested guideline would be to use the MMPI-Afor those 18-year-olds who are in high school and the MMPI-2 for those who are incollege, working, or otherwise living an independent adult lifestyle. (Butcheret al.,1992,p.23)However, in the application of this guideline, it is possible to encounteranadolescentfor whom selection of the most appropriate form would be difficult. For example,an 18-year-old single mother with a 6-month-old infant who is in her senior year inhigh school but living at home with her parents presents a considerable challenge interms of identifying the most appropriate MMPIversion for use with this individual.In such difficult cases, an important question arises concerning what effects, if any,the selection of the MMPI-Aversus the MMPI-2might have on the resulting profilein terms of T-scoreelevation and configuration. Shaevel and Archer (1996)examinedthe effects of scoring 18-year-old respondents on the MMPI-2 and MMPI-A and foundthat substantial differences can occur in T-scoreelevations as a function of this deci-sion. Specifically, these authors reported that 18-year-olds scored on MMPI-2 normsgenerally produced lower validity scale values and higher clinical scale values thanthe same adolescents scored on MMPI-Anorms. These differences ranged as high as15 T-score points and resulted in different single-scale and two-point profile config-urations in 34%of the cases examined. Shaevel and Archer concluded that for thoserelatively rare assessment cases in which selection ofthe proper instrument is difficult,a reasonable practice would be to score the individual on both MMPI-Aand MMPI-2 norms in order to permit the clinician to assess the relative effects of instrumentselection on profile characteristics.Two other studies have examined the effects of scoring 18-year-olds on MMPI-A versus MMPI-2norms. Gumbiner (1997) compared the MMPI-2 versus MMPI-Aprofiles of a group of 18-year-old male and female college students. In general, theresulting MMPI profiles were often dissimilar in terms of codetype classifications,with a marked tendency for MMPI-2profiles to produce greater T-score elevations.Osberg and Poland (2002) also administered both the MMPI-2 and the MMPI-A
  • 67. ADMINISTRATION AND SCORING ISSUES 53to 18-year-old male and female college students. In addition, they used the GlobalSeverity Index (GSI)of the SCL-90-R to classify participants as either psychopathol-ogy present or psychopathology absent to permit an assessment of the usefulnessofMMPI-A and MMPI-2 scores in detecting the presence of psycopathology. Consis-tent with prior findings, the MMPI-A and MMPI-2produced profiles in this studythat were often inconsistent in terms of clinicalelevation status (46% of respondentsproduced incongruent findings). All of the 70 participants in this study who pro-duced incongruent MMPI-2 versus MMPI-Aprofiles had the same overall pattern:clinically elevated MMPI-2 T-scores and normal range MMPI-A T-scores. Further,analysis of incongruent profiles in comparison with subject classification as psy-chopathology present or absent based on SCL-90-R scores indicated that 18-year-oldswere overpathologizedby the MMPI-2 scoresand underpathologizedby the MMPI-Ascores.Reading RequirementsReading level is obviously a crucial factor in determining whether an adolescent cancomplete the MMPI-A. Inadequate reading ability may serve as one of the majorcauses of invalid test protocols for adolescents. Ball and Carroll (1960) found thatadolescents with lower IQs and below-average academic records tended to producehigher Cannot Sayscores, suggesting that the failure to respond to MMPIitems oftenreflects problems in item comprehension.An inverserelationship (r = —.10, p <.05)between reading grade level and raw score values on the Cannot Say scale was alsofound by Archer and Gordon (1991a). This study examined a sample of 495 normaladolescents who receivedthe MMPI-A and the Ohio Literacy Test,a measure ofread-ing comprehension. Thus, adolescents who have difficulty reading MMPIor MMPI-Aitems tend to omit items at a higher frequency than other adolescents.Unfortunately,many adolescents also attempt to respond to items that they cannot adequatelyreador comprehend, often resulting in invalid testprotocols.Formanyyears, asixth-grade reading levelwas generally accepted asa requirementfor MMPIevaluation.Johnson and Bond (1950),for example, assessed the readabilityof MMPI items using the FleschReadingEaseFormula (Flesch,1948)and derived anoverall estimate of sixth-grade reading difficulty for a sample of MMPI items. Thesixth-grade reading level estimate was used in most standard texts on the MMPI.Ward and Ward (1980), however,reevaluated the MMPI items using the Fleschread-ability measure and reported that MMPI items on the basic scales have an averagereading difficulty level of grade 6.7. Individual scale readability levels range fromgrade 6.4 (the Mf scale) to grade 7.2 (the K scale). Their findings resulted in the rec-ommendation that individuals taking the MMPI have a seventh-grade readinglevel.Further increasing reading ability requirements, Butcher et al. (1989) recommendedthat clients have at least an eighth-grade reading level in order to ensure adequatecomprehension of the MMPI-2 item pool. This recommendation was based on theanalysis of MMPI-2items using item difficulty ratings referred to as Lexile ratings inthe MMPI-2manual. Paolo, Ryan, and Smith (1991) also examined the Lexile valuesfor the 567itemsofthe MMPI-2and for eachofthe scalesand subscalesassociatedwiththis measure. Paolo and his colleagues reported that approximately 90%ofMMPI-2items require less than a ninth-grade reading level and that the mean for all itemscorresponded roughly to the fifth-grade reading level. In addition, the authors iden-tified a number of scales or subscales in which at least 25% of the total number ofscale items required more than an eighth-grade reading level. When the MMPI-2 item
  • 68. 54 CHAPTER 3pool is evaluated using other standardized measures of reading difficulty such as theFlesch Reading Ease Formula (Flesch, 1948), however, there are some indications thatthe Lexile ratings may have produced an overestimate of reading requirements. Inthe highest estimate of reading difficulty, Blanchard (1981) reported that 9 years ofeducation was necessary to meet the criterion of accurate comprehension of 90%ofthe MMPI items. As noted by Greene (2000), this reading level appears particularlyrestrictive in that most freshman-level college textbooks are written at a ninth-gradereading level.Part of the difficulty of evaluating the reading requirements of the MMPI involvesthe differences in standardized methods of estimating the reading difficulty of indi-vidual items. Additionally, lack of agreement on the number or percentage of itemsthat must be successfully read and comprehended before an individual is deemedsuitable to take the inventory has added to the variation in estimates. Unfortunately,reading ability is frequently discussed in a dichotomous manner; that is, the subjecteither does or does not have the reading ability to take the MMPI. Many subjects,however, can successfully comprehend some but not all of the MMPI or MMPI-Aitems. The central question concerns the number of items that must be successfullyread in order to ensure the overall validity of the test findings.The MMPI-A manual (Butcher et al., 1992) provides an analysis of the readingdifficulty for each of the MMPI-Aitems using several standard methods of measuringreading difficulty. The methods include the Flesch-Kincaid method, which has beenused in previous studies of the MMPI and other assessment instruments. Based onthe Flesch-Kincaid method, the MMPI-A item pool varies in reading difficulty fromthe Ist-grade to the 16th-grade level. Employing a criterion that at least 80%of theMMPI-A item pool should be accurately read and comprehended in order to ensurevalid test findings, a seventh-grade reading level would be required for theMMPI-A,based on the Flesch-Kincaid reading comprehension standard. This seventh-gradereading level serves as the current recommendation for adolescents evaluated withtheMMPI-A.Dahlstrom, Archer,Hopkins,Jackson, and Dahlstrom (1994) evaluated the readingdifficulty of the MMPI, MMPI-2, and MMPI-A using various indices of reading diffi-culty, including the Flesch Reading Ease index and the Lexile index. One importantfinding derived from this study was that the instructions provided in the MMPI testbooklets tended to be somewhat more difficult to read than the typical item containedwithin the inventories. Therefore, clinicians should ensure that the instructions arefully understood by respondents, and it is often appropriate to ask the test taker toread the instructions aloud and explain their meaning in order to ensure adequatecomprehension. The average difficulty level for all three forms of the MMPI wasapproximately the sixth-grade level. The MMPI-A test instructions and items wereslightly easier to read than the MMPI-2 or the original version of the MMPI; however,the total differences tended to be relatively small. If the most difficult 10%of itemswere excluded, the remaining 90%of items on all three versions of the MMPI had anaverage difficulty level of grade 5. On average, the most difficult items appeared onscale 9, whereas the easiest items tended to be within the item pool of scale 5. Theauthors also reported, based on the Flesch Reading Ease index, that approximately6% of the MMPI-A items required a lOth-grade reading level or better. Dahlstromet al. noted that the number of years of education completed by a subject is often anunreliable index of the individuals reading competence.Adolescents reading abilities may be evaluated by the use of any of a numberofreading comprehension instruments, including the Gray Oral Reading Tests (GORT;
  • 69. ADMINISTRATION AND SCORING ISSUES 55Gray &Robinson, 1963; GORT-R;Wiederholt &Bryant,1986), the Peabody IndividualAchievement Test-Revised (PIAT-R; Markwardt, 1989), and the reading componentof the WideRangeAchievementTest-Third Edition (WRAT-III; Wilkinson, 1993). Re-sults of analyses by Dahlstrom et al. (1994) indicated that both the GORT and theWechsler Individual Achievement Test (WIAT; Wechsler,1992) showed a relativelysmooth progression of scores in relation to student grade levels, and both measureswere recommended if a reading test is to be employed for evaluating an individualscompetence to deal with the item difficulty of any version of the MMPI.Areasonablyaccurate reading screen canbe devised,however,by requesting the adolescent to readaloud and explain several MMPI-A items. Theitems that appear to be the most usefulmarkers inthisregardareitemsthathavean eighth-gradereadinglevelrating. Amongthe initial abbreviated MMPI-A test statements, eighth-grade level items include thefollowing:5. Easily awakened by noise.17. Often nauseated.18. Seldom constipated.25. Upset stomach.29. Unusualexperiences.An adolescent may havedifficulty in responding to the MMPI-Abecause ofspecificreading ability deficits, in contrastto limitations in overallintellectualcognitive func-tioning. Under these circumstances, administration may stillbe undertaken using thestandardized audiotape versions ofthis instrument available through Pearson Assess-ments. Generally, procedures in which an examinerreads test items to the adolescentare not recommended because of the degree of intrusion into the response processassociated with this method. Researchby Newmark (1971), for example, indicatedthat MMPI profiles produced by adolescentsfor whom items were read aloud by anexaminer had higher K scale scores than profiles obtained with traditional adminis-tration methods. In contrast,Brauer (1992) showed that there is no significant effectfound for the signer when selected MMPI items were translated into American SignLanguage and recorded on videotape for use with hearing-impaired or deaf individ-uals. If an adolescent scoresbelow 70 on the standardized IQ assessment measure orhas less than a fourth-gradereading level, administration of the MMPI-A should notbe attempted through any format.When questions are asked by adolescents concerning the specific meaning of anMMPI-A statement or word, the examiner should attempt to provide useful but neu-tral information. For example,dictionarydefinitionscan be given for commonlymis-understood words (e.g.,constipation, nausea,or diarrhea). However, the frequency withwhich adolescents encounter unfamiliar or awkwardly worded items should be re-duced on the MMPI-A, in comparisonwith the originaltest instrument,because 69 ofthe original items havebeen reworded or modifiedin order to improve the readabilityof the MMPI-Aand/or its relevance to contemporary adolescents life experiences.Research by Archerand Gordon (1994) and Williams,Ben-Porath, and Hevern (1994)indicated that these revised items may be considered to be psychometrically equiv-alent to the original items in terms of response characteristics. When questions areraised by the adolescentconcerning itemsthathe or she clearlyunderstandsand com-prehends, however, the examiner must always be careful to remind the adolescent to
  • 70. 56 CHAPTER 3respond to the item as it applies to him or her and to base the answer on his or herown judgments and opinions.Despite reasonable efforts to evaluate reading ability, the clinician is likely to en-counter adolescents who have responded to the MMPI-Aitem pool without readingand/or understanding many items. Nonreading or noncomprehension may occurbecause of reading deficits, motivational issues, or a combination of these factors.A simple method of checking for most types of random response patterns involvesrecording the total MMPI-A administration time. Total administrationtime providesone useful index for aiding in the identification of random response sets among ado-lescents,particularly when the administration time isunusually brief (e.g.,less than40minutes for the full-length MMPI-A). Unless the test administration time is recorded,however, this valuable information source is lost. Other methods of detecting poten-tial problems in reading ability based on MMPI-Ascales, including TRIN and VRIN,are discussed in chapter 4.MMPI-A TranslationsTheoriginal version ofthe MMPIwas translated intoawide range offoreign languagesand there was an impressive amount of research on the cross-cultural applicationsofthis test instrument. The MMPI-2 is currently availablein a wide array of languages,including Croatian, Czech, Dutch/Flemish, French, French-Canadian,German,He-brew, Hmong, and Italian, and three Spanish language translations exist for use inthe United States. Several other foreign language translations are currently underway,into Japanese, Korean, Chinese, Thai, Vietnamese, Chilean Spanish, Norwegian, Ice-landic, Russian, Greek, Arabic, and Farsi (Butcher, 1996). The MMPI-A is followingin the same tradition, and there is currently a Spanish version available for use inthe United States, a Spanish version for use in Mexico, and Dutch/Flemish, French,and Italian translations. Cheung and Ho (1997)recently evaluated a Chinese languageversion of the MMPI-Ain a sample of565boys and 664girls aged 14-18 in HongKongschools settings. The authors concluded that moderate elevations shown on severalscales using T-scores based on the U.S. adolescent norms indicate possible culturaldifferences in the reporting of psychopathology on the MMPI-A. In addition,severalother MMPI-A translation projects are currently in progress.Supervision RequirementsIt is important that the adolescent be provided with an appropriate testing environ-ment in which to complete the MMPI-A. This environmentshould includeadequateprivacy and supervision. The testing environment should be as comfortable as pos-sible, with a minimum of extraneous noise or other distractions. It is inappropriateto allow an adolescent to complete the MMPI-A in any unsupervised setting or ina setting in which privacy cannot be assured, such as at home or in a clinic waitingroom. Unsupervised test administration does not provide adequate data for validtest interpretation and is subject to successful legal challenge if the findings are pre-sented in a courtroom. Adequate test supervision means that a proctor or examinerisavailable to continuously monitor the test-taking process and to provide appropriateassistance when necessary. Adequate proctoring does not require, however, that theproctor monitor each individual response by the subject or otherwise become overlyintrusive.
  • 71. ADMINISTRATION AND SCORING ISSUES 57Increasing Adolescents Cooperation With Testing ProceduresA final criterion in the evaluation of adolescents involves their willingness to answerthe lengthy item pool of the MMPI-A. For the angry and oppositional adolescent,the MMPI-A may present a welcome opportunity to exhibit hostility and resistanceby refusing to respond to items or by responding in an inappropriate or randommanner (Newmark & Thibodeau, 1979). Once the adolescent has entered into an"anal-retentive" struggle with the examiner over test completion, there is often littlethe examiner can do that will effectively decrease the conflict. Prior to the administra-tion of the MMPI-A,however, several steps may be taken to increase the motivationof most adolescents. These include (a) establishing adequate rapport with the ado-lescent prior to testing, (b) providing clear and concise instructions concerning thepurposes of testing, and (c)providing the adolescent with an opportunity to receivetesting feedback.Clear and concise instructions should be given to the adolescent so that he or shehas a general understanding of the purposes of the MMPI-A administration. Whenclear instructions are not provided, many adolescentswill project their own meaningonto the testing in a manner that may serve to render test results invalid. For example,an adolescent may erroneously believe that the test results will beused by the therapistto determine whether a psychiatrichospitalization is indicated or to mete out blameor punishment for family conflict or family dysfunction. Poorly worded instructionsmay also negatively influence a subjects test-taking attitude and cooperation withtesting procedures. The instructions, therefore, should be carefully presented in thestandardized manner. The adolescent should read the instructions provided in theMMPI-A test booklet and also receive a verbal summary,which might, for example,include the following: "Read each statement and decide whether it is true as appliedto you or false as applied to you. Remember to give your own opinion of yourself.There are no right or wrong answers. Your test results will help us to understandyou."In addition to these introductory instructions, adolescents frequently ask questionsconcerning various aspects of testing, which often reflects their anxiety concerningthe evaluation process. The following are frequently encountered questions, withsuggested responses, as adapted from the CaldwellReport(Caldwell,1977a)and fromFriedman et al.(2001).1. Q. How long will this take?A. About an hour to an hour and a half, usually. Some teenagers take longer,whereas other teenagers finish in less time.2. Q. Will it make any difference if I skip some questions and come back to them?A. If you do it carefully, skipping some questions and returning to them prob-ably will not make any difference. But it is easy to get mixed up in markingyour answers, and that will make a difference, so it is better to do them inorder, if possible.3. Q. Suppose I cannot answer all the questions?A. Tryto answer all of them. Ifyou omit a few items, it will not matter,but try todo them all.Whenyou are finished,takea few minutes to checkyour answersheet for any missing answers, incomplete erasures, or double-answeredquestions.
  • 72. 58 CHAPTER 34. Q. What is the MMPI-A?A. MMPI-A is short for the Minnesota Multiphasic Personality Inventory-Adolescent. It is a widely used test to help understand the kinds of problemsthat happen to teenagers.5. Q. How do I try to answer these questions?A. Answer the questions as you currently feel. Work quickly, and do not spendtime worrying over your answers.6. Q. What if I dont agree with the results from the test or the test results arewrong?A. That is something that you and I will get a chance to discuss during thefeedback process. Teenagers often learn some things about themselves thatthey did not know, and the therapist often learns which parts of the testingwere more accurate than others. It is hoped we will both learn somethingfrom the feedback process.It is important to present the MMPI-Ato adolescents in a careful and serious man-ner that underscores the importance of the testing process. Attempts to assist theadolescent in feeling more comfortableby minimizing the importanceof theMMPI-Aevaluation are usually counterproductive. A "casual" presentation of the MMPI-Amay actually result in a reduction in the adolescents cooperation and motivationtocomplete testing because his or her doubts about the importance of the test findingswill appear to have been validated.Providing Test Result FeedbackIn addition to establishing rapport with the adolescent prior to testing and provid-ing clear and concise test instructions, it is very helpful to inform the adolescentthat he or she will receive feedback on the test results. If an adolescent does nothave the opportunity to learn from the testing experience, there is often little in-herent motivation to cooperate with the demanding testing procedures. Finn andTonsager (1992) reported data indicating that the provision of MMPI-2 feedbackto college students awaiting psychotherapy was associated with a significant de-cline in subjects psychological distress and a significant increase in their levels ofself-esteem. The MMPI or MMPI-2 test feedback process is discussed in detail inthree texts: MMPI-2 in Psychological Treatment (Butcher, 1990), Therapist Guide to theMMPI and MMPI-2: Providing Feedback and Treatment (Lewak, Marks,& Nelson, 1990),and Manual for Using the MMPI-2 as a Therapeutic Intervention (Finn, 1996). In addi-tion, a computer software package was developed by Marks and Lewak (1991) toassist clinicians jn providing meaningful MMPI test feedback to adolescent clientsand was revised to include feedback for the MMPI-A. The interpretive informa-tion provided in this report includes statements designed to be provided directly toclients.Archer and Krishnamurthy (2002) emphasized a method of providing feedback tothe adolescent that enhances the adolescents curiosity about the testing process andincreases the personal relevance of the test findings. Adapting the generalguidancegiven by Finn (1996), these authors recommend actively engaging the adolescent inconstructing questions that canbe answered from test findings prior to the administra-tion of the MMPI.The ultimate goal is to encourage the adolescent to produce aman-ageable number of practical issues or questions that can be systematically addressed
  • 73. ADMINISTRATION AND SCORING ISSUES 59in test feedback. Archer and Krishnamurthy presented the following example of atypical discussion that might ensue in this collaborative process (pp. 24-25):Examiner: I understand that you are not sure about how this testing may beuseful to you. Often, this type of testing helps teenagers to learnthings about themselves that they hadnt been fully aware of, oractively thought about.Adolescent: What kinds of things?Examiner: For example, most people dont really think about how they comeacross to other people,or whether their ways ofthinking and feelingare very different from those of others. The MMPI-Acan shed lighton these issues. Does that make sense to you?Adolescent: I guess.Examiner: The testing could also help you to better understand things thatadolescents might already suspect about themselves. For example,a teenager might be aware that she often feels unhappy or grouchybut not have aclearidea about whatsgoing on.TheMMPI-A resultsmay help her to realize that she is depressed, which may includebeing very sensitive to others reactions, having negative thoughtsabout herself, and feeling that no one really understands her. Doesthis give you an idea of how this works?Adolescent: Yes.Examiner: Okay. Now all of this can be best done if you take a few momentsto think about some questions you have about yourself that youwould like answered by the testing.Adolescent: Uh... about feeling depressed?Examiner: The type of question varies from person to person and is up to you.What are some things that you have wondered about regardingyourself?Adolescent: I dont know.... Sometimes I feel that everyone in my class, and allmy friends, are so sure of themselves and know what they wantbetter than I do.Examiner: That is a good place to start. It sounds like you feel uncertain aboutyourself and your goals and dont feel like you have as much con-fidence as other teenagers. Is that correct?Adolescent: Yes.Seems like Im the only one who doesnt have a clue.Examiner: The question for testing, then, can be, "Am I low in self-confidenceand self-esteemcompared toother teenagers?" How does that sound?Adolescent: That sounds right.Examiner: Good. TheMMPI-A can certainly give us an answer to this questionand help us seewhat kinds ofthings contribute to this feeling. Letsmake a note of that question and then try another one.Adolescent: Well, I also get mad at people who show off or are in my face. Myparents make me mad too. I can really pitch a fit and it comes outof nowhere. I guess I wonder why I blow up so easily.Examiner: That is an excellent issue for which we should get useful informa-tion from the MMPI-A.Itsoundslikethere are two related questionshere, one being, "Do I get angry more quickly than other people?"and the other one being, "Why do I get easily angered?"Adolescent: Thats exactly it.
  • 74. 60 CHAPTER 3Archer and Krishnamurthy noted that this collaborative process involves the adoles-cent identifying issues ofconcern and the examiner helping to restate and clarify theseissues. This preadministration dialogue should be conducted in an unhurried paceuntil a satisfactory list of queries has been produced. Archer and Krishnamurthy alsonoted that modified versions of this procedure may be used. For example, the ado-lescents legal guardians might be included in the process, or, alternatively, anotherreferring professional who is involved in the adolescents care might act as the adultparty in the collaborative process.Butcher (1990)provided general guidelinesfor MMPI-2 feedbackthat arealso appli-cable to the MMPI-A. Forexample, Butcherrecommends that the therapist explainthetest to the client, including giving a brief description of the meaning of the scales andT-scores, and that the therapist then review the clients scores in relationto testnorms.Furthermore, responses are encouraged from the client during the feedback processin order to make it an interactive experience. Butcheralso underscored the therapistsneed to appraise the degree of acceptance of test feedbackby asking the client to sum-marize his or her understanding of and reaction to major findings. Butchercautionedthat the therapist should present feedback as "provisional" information and shouldgauge how much feedback the client can realisticallyabsorb or incorporatewithoutbecoming overwhelmed or excessivelydefensive.The feedbackapproach favoredby Lewaket al. (1990)and Marksand Lewak (1991)is described as an empirical-phenomenological approach based on the theoretical for-mulations ofAlexCaldwell. Caldwell (1976,1977b, 2001)postulated that MMPIscalesmeasure dimensions of psychopathology that are related to fear-conditioned defen-sive responses. These defensive responses are acquired as a result of the interactionbetween individuals predispositions and the occurrence of certain environmentalstresses during their development. Table 3.2 lists each of the eight clinical scales forwhich Caldwell described an associated fear-conditioned defensive response.TABLE 3.2MMPI-2 Scales and Associated Fear-Conditioned Defensive Responses Postulated by Alex CaldwellScale Fear Response1 Death, physical attack, illness, Maintaining physical integrity by overprotecting theor pain body2 Significantand irretrievable loss Blocking of wanting or needing in order to avoidfurther loss3 Emotional pain Positivizing unpleasant experiences by selectively blockinginputs (e.g., blindness, numbness)4 Rejection,being unwanted or "Numbing out" emotional responding, not allowing oneselfabandoned to get emotionally involved to avoid letdown6 Being criticized, devalued, or Maintaining constant vigilance against attackhumiliated7 Shock, unexpected and Thinking ahead and worrying to anticipate onset of shockunpleasant events8 Hostility, being disliked or "Shutting down" cognitive processing to avoid unbearabledespised by those on whom realityone depends9 Deprivation or failure Increasing activity level in an attempt to maintain rewardscheduleNote.

  • 75. ADMINISTRATION AND SCORING ISSUES 61The Caldwell model provides a basis for offering nonthreatening feedbackto ado-lescent and adult clients. Much of the traditional descriptive literature regardingMMPI interpretation, however, contains psychological terms that may be viewed byclients as negative, pejorative,critical, or irrelevant.The Lewak et al. (1990)approachto providing feedback attempts to move beyond this problem. Their feedback strat-egy focuses on the clients phenomenological experience of the stressors that initiallyinduced maladaptive response patterns rather than providing an objective clinicaldescription of the defenses themselves. For example, Lewak et al. noted that highT-score values for MMPI scale 1 are typically related to descriptions that emphasizepersonality characteristics such as immaturity, dependency, psychological naivete,and excessive preoccupation with somatic concerns. From the clients perspective,however, high scale 1 elevations may represent a reasonable response to the percep-tion that his or her physical health is fragile and that their physical integrity may bethreatened by pain, illness, or even death. Therefore,feedbackstatements for markedelevations on scale 1 include the following:Your body is a constant source of anxiety and fear for you, so right now your worriesabout health take up most of your time and energy. This constant fear and worry aboutyour physical health may be taking its toll and leaving you feeling extremely defeated,pessimistic, and bitter.Youmay even find yourself resigned to living the rest of your lifechronically ill and in pain. Youprobably have to rely on others to help you in your dailyliving; this is usually very frustrating for you. (Lewak et al., 1990,pp. 55-56)Test Administration Proceduresto IncreaseCooperationSeveral additional steps may be taken in order to increase adolescents willingnessto cooperate with testing procedures. For example, it is often preferable to divide theadministration of the MMPI-Abetween several sessions in cases where the total testadministration can be spread over a few days. If the administration is attempted inone session, it is advisable to provide a rest period whenever the adolescent becomesfatigued. Placement of the MMPI-Aat the earlier stages of an extensive test batterydecreases the probability that an adolescent will employ a random response set inorder to finish the testing session as quickly as possible. Finally, a clinician may electto administer only the first 350items of the MMPI-Aas an abbreviated administrationof the test. This administration format utilizes only those items necessary to score thestandard validity and clinical scales. Ifthe motivation or cooperation ofthe adolescentwould be increased significantlyby using an abbreviated administration format,oriftime restrictions necessitate this format, this option allows the clinician to fully scoreand interpret the standard clinical scales and the Harris-Lingoes and Sz subscales.Abbreviated administration of the MMPI-Adoes not, however, provide informationconcerning the content scales, several of the supplementary scales, or validity scalesVRIN, TRIM, F1 and F2.Short Form IssuesBall, Archer,and Imhof (1994) reported findings from a national survey ofpractition-ers related to the time requirements associated with the administration, scoring, andinterpretation of 24commonly used psychological test instruments. Findings derivedfor the MMPI indicated a mean administration time of 66.16 minutes and a modal
  • 76. 62 CHAPTER 3value of 90minutes. This modal time estimate was exceeded only by the time require-ments associated with administration of the Halstead-Reitanneuropsychological testbattery.In response to the problems created by thelengthy MMPIitem pool, Newmarkand Thibodeau (1979) recommended the development and use of short forms of theMMPI in the assessment of adolescents. As defined by Butcher and Hostetler (1990),the term short form is "used to describe sets of scales that have been decreased inlength from the standard MMPIform. An MMPI short form is a group of items thatis thought to be a valid substitute for the full scale score even though it might containonly 4 or 5 items from the original full scale" (p.12).The MMPI-168was developed by utilizing the first 168 items to appear in the groupbooklet form ofthe MMPI(Overall &Gomez-Mont, 1974).The 71-itemMini-Mult wasdevised by Kincannon (1968) based on factor analyses used to identify item clustergroups. Investigations of MMPI-168 characteristics in adolescent samples were doneby MacBeth and Cadow (1984) and Rathus (1978). In addition, Mlott (1973) reportedMini-Mult findings for adolescent inpatients. Vondell and Cyr (1991) evaluated theinfluence of gender on eight MMPI short forms, including the Mini-Mult and theMMPI-168, in a sample of 318male and 248female adolescentpsychiatric inpatients.The authors concluded that gender differences occur on all of these short forms inadolescent populations, a result that parallels similar findings obtained in short forminvestigations of adult samples.Butcher (1985) and Butcher and Hostetler (1990) noted a series of potential prob-lems with the use of MMPIshort forms: The smaller number of items in MMPI scalesin short form versions reduces the overall reliability of the measurement of scaleconstructs. The shortened versions of the MMPIhave also not been sufficiently vali-dated against externalcriteria.Additionally,the short form profiles and codetypes arefrequently different from the results that would have been achieved from the admin-istration of the full MMPI item pool. Research by Hoffmann and Butcher (1975), forexample, showed that theMini-Mult and the standard MMPItend toproduce the sameMMPI codetypes in only 33%of cases and that the standard MMPIand the MMPI-168produce the same codetypes in only 40%of adult cases. Consistent with these find-ings, Lueger (1983)reported that 2-point codetypes derived from the standardMMPIand the MMPI-168 were different in over 50% of a sample of male adolescents.Greene (1982) suggested that short forms of the MMPImay constitutenew test mea-sures that require additional validation to identify external correlates. In additionto issues related to scale reliability and codetype congruence, Butcher and Hostetler(1990) questioned the ability of the MMPIshort forms to accurately determine profilevalidity.The problems with MMPI short forms identified in studies with adult popula-tions appear to have important implications for clinical and/or research uses of theMMPI-A. In particular,there is a significant loss of valuableclinicalinformation whenshort forms are used in place of the full MMPI. The use of a short form procedure,although it saves administration time, appears likely to introduce more than an ac-ceptable range ofconfusion and "noise" into the interpretation process for adolescentprofiles. In recognition of these problems, no efforts were made by the MMPI-2 orMMPI-A advisory committees to preserve any of the currently existing MMPIshortforms. Consequently, as noted by Butcher and Hostetler (1990), "Some of the itemsconstituting previously developed MMPI short forms may have been deleted fromthe MMPI in the revision process" (p. 18).Archer, Tirrell, and Elkins (2001)recently reported psychometric properties relatedto a short form of the MMPI-A based on the administration of the first 150 items
  • 77. ADMINISTRATION AND SCORING ISSUES 63of this test instrument. Results were based on analysis of the MMPI-A normativesample of 1,620adolescentsas well as a clinicalsample of 565adolescents in a varietyof treatmentsettings.Correlationalanalysisshowed short-form to full administrationbasic scale score correlations in the range of .71 for the Mf scale to a high of .95 forthe L scale when computed for all the MMPI-A basic validity and clinical scales.In addition to the correlationalanalyses, these authors also examined the degreeofdifference found in mean T-scorevalues produced for the MMPI-A basic scales by thefull administration ofthe test instrument and when T-scorevalueswere prorated fromMMPI-A short form results. Although comparisons for several ofthebasic validity andclinical scales reached significance,at least partially because a relatively large samplesize wasutilized inthese analyses, themeanT-scoredifferences between the actual andprorated values exceeded2T-score points onlyfor scales4and 9in the clinicalsample.Further, these analyses showed relatively high scale correlations and mean profilesimilarities but relatively lower rates of congruence in profile configural patterns.Specifically, only 30.6%of the normative sample and 32.2%of the clinical sampleproduced basic scale profiles that were congruent (i.e., identical 2-point elevationsproduced by short form and full-length administrations). The potential advantagesof the MMPI-A150 included a reduction of the total item pool of nearly 70%and areduction in the typical administration time from 60to 20minutes. This item and timesavings, however,appeared tobelargely offset by the limitations in profile congruencyillustrated in this study and in all prior research findings related to MMPI shortforms.The use of MMPI-A short forms, in contrast to an abbreviated administration, isnot recommended in the assessment of adolescents. As previously noted, however,the abbreviated form of the MMPI may serve as a reasonableresource in coping withpoorly motivated or resistant adolescents. Additionally, several approaches to abbre-viating the administration of the MMPI-2 item pool by adapting MMPI-2items tocomputer administration are currently being developed and evaluated (e.g., Ben-Porath, Slutske, &Butcher, 1989;Roper,Ben-Porath,&Butcher,1991,1995). Computer-adapted administration approaches present only those items that would add clini-cally relevant information about the client given the clients prior MMPI-2responses.Several approaches have been developed for this purpose, including one based onitem response theory (IRT) and another on the countdown method, the latterapproachterminating item administrationfor a given scale once sufficient information for thatscale has been obtained from the respondent. Butcher and Hostetler (1990) noted thatalthough none of these approaches are currently practical, it is likely that effective,adaptive programs will eventually be developed for automated administration ofthe MMPI-2and MMPI-A. In this regard, Forbey, Handel, and Ben-Porath (2000) re-cently evaluated a real data simulation of a computerized adaptive administration ofthe MMPI-Aconducted using the item responses from three groups of participants.The first group included 196 adolescents (aged 14 through 18) tested at a midwest-ern residential treatment facility for adolescents, the second group consisted of theMMPI-A normative sample, and the third group was the clinical sample reportedin the MMPI-A test manual (Butcher et al., 1992). The MMPI-A data for each groupwere run through a modified version of the MMPI-2 adaptive testing computer pro-gram to determine the amount of item savings produced by simulations based onthree different orderings of MMPI-A items. These orderings included the presen-tation of items from least to most frequently endorsed in the critical or key direc-tion, the presentation of items from least to most frequently endorsed in the criticalor key direction with the qualification that the first 120items are arranged in their
  • 78. 64 CHAPTER 3usual booklet order, and the presentation of all items as presented in the test book-let. The mean number of items administered for each group was computed for eachadministration using T-score cutoffs of 60 and 65 to define clinical range elevations.Substantial item administration savings were achieved for the groups, and the meannumber of items saved ranged from 50 items to 123items (in contrast to the 478-itemtotal item pool), depending on the T-score cutoff classification method. This studyshows that the development of a computerized adaptive administration format forthe MMPI-Aholds the promise of reduced administration time.TEST MATERIALSOriginal MMPI FormsSeveral forms ofthe original MMPIwere developed,including the MMPIGroup Form,which was a reusable group booklet, and MMPI Form R, which was a hardcover,spiral-bound test booklet. Of these two, the Group Form was more widely used.Furthermore, as Greene (1980) noted, most of the MMPI research literature has beenbased on data derived from the Group Form.The Form Rbooklet isparticularlyuseful,however, when a subject does not have a hard surface on which to enter responses tothe test items. The Form R answer sheet is inserted over two pegs in the back of thetest booklet. Form R pages are arranged in a step-down format such that the turningof each consecutive page reveals another column of answer spaces matched with thebooklet column of the corresponding questions. The step-down format allows onlyone column of questions and answers to be shown at a time, thereby reducing thepossibility of misplacing a response to a specific question.The numbering system for items in the Group Form booklet and Form Rbookletofthe original MMPIwere identical for the first 366 items but diverged for the latter partsof the item pool. This discrepancy created substantial confusion for both researchersand clinicians. Dahlstrorn et al. (1972), however, provided tables for converting be-tween the Group Form and Form R. An abbreviated administration of the first 399items on Form R permitted the scoring of all basic standard and validity scales. Un-fortunately, there was not a straightforward method of performing an abbreviatedadministration of the Group Form booklet.On September 1, 1999, the University of Minnesota Press and the test distributor(Pearson Assessments) discontinued publication of the original version of the MMPI.This version was discontinued because the material surrounding its use had becomeconsiderably dated and the MMPI-2 and MMPI-A had largely replaced it in clinicaland research uses. The University of Minnesota Press also noted that the concurrentuse of the original version and the revised versions had become a source of poten-tial confusion for many test users, particularly those in forensic settings. Further, theMMPI-2 and MMPI-A had the benefit of containing a more appropriate and con-temporary item pool as well as more contemporary and nationally representativenormative samples.MMPI-A Test MaterialsTesting materials related to the use of the MMPI-A (and the MMPI-2) are availablefrom Pearson Assessments. Fortunately, the order of the 478 items in the softcover,
  • 79. ADMINISTRATION AND SCORING ISSUES 65hardcover, and audiocassette versions of the MMPI-A is identical, and the items arearranged in such a way that the standard validity and clinical scales may be scoredbased on the administration of the first 350items. It should again be noted, however,that the contentscales and several of the supplementary scales of the MMPI-A cannotbe scored when an abbreviated administration is utilized, resulting in the loss ofvalu-able information. The audiocassette version of the MMPI-A is useful for the visuallyimpaired as well as for adolescents with sufficient reading-related disabilities to makestandard form administration impractical. Administration of the audiocassette ver-sion requires approximately 1hour and 40minutes (Archer &Krishnamurthy, 2002).Software for computerized administration of MMPI-A items can also be purchasedfrom Pearson Assessments.Different answer sheets are available for the MMPI-A, depending on whether theexaminer intends to score the test using hand-scoring keys or by computer.Therefore,the examiner should consider the scoring mechanism that will be utilized beforeselecting the answer sheet. It should be noted that answer sheets designed for theoriginal MMPI or the MMPI-2are not applicable to the MMPI-A.SCORING THE MMPI-AThe examiner should take substantial care to eliminate the common sources of errorthat occurin scoring and profilingMMPI-Aresponses. This process should startwithacareful examinationofthe adolescents answer sheet to ensure that items were not leftunanswered or endorsed in both the true and false directions. Additionally, answersheets should be examined for evidence of response patterns indicative of randommarkings or all true or all false response sets.Obtaining the raw scores for all ofthe MMPI-Astandard and supplementary scalesmay be accomplished by computer orhand scoring. Ifhand scoring isused, conversionof raw scores to T-score values should be done using MMPI-Aprofile sheets based onthe gender-specific adolescent norms for this instrument. Adolescent profilesheets forthe MMPI-Aare available from Pearson Assessments; these use the normative valuesfor the MMPI-A described and presented in the MMPI-A manual (Butcher et al.,1992) and in Appendix C of this text. It is important to realize that the raw score X-correction procedure is not used in deriving or profilingT-scores for adolescents withthe MMPI-A.As previously noted, Marks et al. (1974) reported several reasons whythe K-correction procedure was not developed for adolescent norms, including theirpreliminary evidence that adolescent MMPI profiles achieve greater discriminationbetween adolescent subgroups without the addition of a X-correction factor. As ispresented in more detail later, an investigation by Alperin, Archer, and Coates (1996)examined the effectiveness ofa X-correction factor for the MMPI-Aand concluded thatthe adoption of a K-correction procedure would not result in systematic improvementin test accuracyfor this instrument.As reviewed by Archer (1989) and, more recently, by Archer and Krishnamurthy(2002), the procedures for scoring and profiling adolescent responses may be sum-marized as follows: First, carefully examine the answer sheet for evidence of deviantresponse sets, unanswered items, or double-marked items. Second, obtain the rawscore value for each scale using the computer scoring reports available from Pear-son Assessments or the hand-scoring keys. Third, convert the non-X-corrected rawscores to T-scores for each scale using the appropriate adolescent norm tables, with
  • 80. FIG. 3.1. MMPI-A Profile for Basic Scales (Male).
  • 81. ADMINISTRATION AND SCORING ISSUES 67particular attention to the gender of the respondent. Fourth, plot T-score values onthe MMPI-A profile sheet. The MMPI-AProfile for Basic Scales (male form) is shownin Fig. 3.1.Scoring of the MMPI-A may be accomplished through several different methods.A computer software program is available from Pearson Assessments that permitstest users to administer and score the standard validity and clinical scales as well asall other scales, including the content and supplementary scales, using their personalmicrocomputers. Specifically, the Basic Scale Profile Report provides raw scores andT-scores for 4 validity scales (L, F,F1, K) and the 10basic clinicalscales and is suitablefor scoring an abbreviated administration encompassing the first 350MMPI-A items.The Extended Score Report includes raw scores and T-scores for all MMPI-A scalesand subscales, including a list of items omitted by the adolescent. An example of theoutput from the MMPI-A Extended Score Report is included in Appendix 3.1. Thetest may also be administered via paper and pencil, with the responses hand scoredor key entered into the scoring package later by trained support staff. High-volumetest users might wish to consider the scanner option for their personal computer, inwhich answer sheets are scanned and responses tabulated by the scoring program.In addition, answer sheets may be mailed to Pearson Assessments (in Minnesota),which will score the test responses and return the results to the test user.In addition to computerized scoring services, hand-scoring templates for use withspecialized answer sheets are available for allMMPI-Astandard, content,and supple-mentary scales and for all subscales. The template for a given scale is placed over theanswer sheet, and the darkened spaces are counted; the total is the raw score for thatscale. Special care should be taken when scoring scale 5 (Masculinity-Femininity) touse the scoring key designed for the adolescents gender, and caution should also beused in scoring TRIN (TrueResponse Inconsistency) and VRIN (VariableResponse In-consistency), given the complexity of the scoring for these scales. The TRIN and VRINscales require separate recording grids for hand-scoring purposes, and the scoringformats for these validity scales are described in more detail in chapter 4.A recordinggrid for the TRIN scale is shown in Fig. 3.2.Computer Administrationand Scoring IssuesThere are several special considerations that should be evaluated when using com-puter software for administering or scoringthe MMPI/MMPI-A.Withonline adminis-tration ofthe inventory,clear instructions for entering and changing responses shouldbe provided to the respondent. The examiner should ensure that the respondent isinstructed in how to accurately enter or change responses. The respondents entryof responses should be monitored to ensure that he or she understood the instruc-tions. Computer administration programs often have summary or editing screens thatpermit the monitoring of item omissions.Several studies have examined the possibility that computer-administered MMPIscores may differ from scores produced by administration of the instrument usingthe standard test booklet. Watson, Thomas, and Anderson (1992) undertook a meta-analysis that compared the MMPI scaled scores produced by standard test book-let and computer administration as reported in nine studies encompassing 967 re-spondents. Theauthors found that computer administration produced systematicallylower scores than standard test booklet administration, although these differenceswere relatively small and typically accounted for less than 1.5 T-score points. They
  • 82. 68 CHAPTER 3FIG. 3.2. TRIN Scale Recording Grid.
  • 83. ADMINISTRATION AND SCORING ISSUES 69concluded that the underestimates due to computer administration, although small,appeared consistent enough to suggest that the development of separate norms andprofile sheets might be useful for computer-administered protocols, particularly forbasic scales 3,4, and 8.As previously noted, a mail-in scoring service is available for the MMPI-A. Whenthis option is used, the respondent enters his or her responses on thecomputer-scoredMMPI-A answer sheet, which is sent to Pearson for scoring and reporting. As withthe hand-scored version ofthe MMPI-A,the computer-scored answer sheet should bechecked by the examiner for item omissions, double-marking, and deviant responsesets before being sent for processing. The clinician should also eliminate any straymarks or incomplete erasures because these may be interpreted as valid responses inthe computer-scoring process. These same cautions apply to examiners who use in-office scanning equipment for response entry.Although clinicallore has held that thedegree of neatness or sloppiness displayed by the respondent in filling out an MMPIresponse sheet may be related to personality features, findings by Luty and Thackrey(1993) provided no evidence of a meaningful relationship between neatness and testscores. MMPI-A users who elect to employ a computer-scoring method should beaware that the profiles will be printed only if the age entered is within the 14-18 agerange inclusive.Selection of Appropriate NormsThe adolescent norms to be used with the MMPI-Aare based on the MMPI-A norma-tive sampledescribed in chapter 2and provided in Appendix Cofthis text.BecausetheMMPI-2 was specifically created for adult respondents, and adolescent norms havenot been developed for this form, the MMPI-2 should not be used with respondentsunder the age of 18 (Butcher et al., 1989).Archer (1984, 1987b) discussed in detail the statistical and interpretive problemsrelated to the use of adult norms when applied to adolescent response patterns. Inparticular, the use of adult norms with adolescent clients tends to overestimate theoccurrence and degree of symptomatology related to conduct disorder and antisocialpersonality features as well as psychotic and schizophrenic disorders.Adolescent Norm Transformation ProceduresThe adolescent norms developed by Marks and Briggs (1972)for the original form ofthe MMPIwere based on linear transformation procedures that convert raw scores toT-score values. These are identical to the transformation procedures used in develop-ing the adult norms for the original MMPIby Hathaway and McKinley (Dahlstromet al., 1972). The MMPI-A retains the use of linear T-scoresfor the validity scales (i.e.,VRIN, TRIN, F-1,F2,F,L, and X), for scales5 (Masculinity-Femininity) and 0 (Social In-troversion), and for the supplementary scales,including the MacAndrewAlcoholismScale-Revised (MAC-R) and the Alcohol/Drug Problem Acknowledgment (ACK),Alcohol/Drug Problem Proneness (PJRO), Immaturity (/MM), Repression (R), andAnxiety (A) scales. Eight of the clinical scales on the MMPI-A (1, 2, 3, 4, 6, 7, 8, and9) and all of the 15 content scales have T-score values derived from uniform T-scoretransformation procedures.Uniform transformationprocedures were developed to address a problem that hasbeen associated with the use of linear T-score values for the MMPI. This problem is
  • 84. 70 CHAPTER 3that identical T-score values do not represent the same percentile equivalents acrossthe standard MMPI scales when derived using linear procedures. This phenomenonoccurs because MMPI scale raw score distributions are not normally distributed, andthe degree to which they vary from the normal distribution fluctuatesfrom scale toscale. Thus, using linear T-score conversion procedures, a T-score value of 70on onescale may not represent a percentile value equivalent to that represented by aT-scorevalue of 70 on another MMPI clinical scale. This discrepancy resulted in difficultieswhen directly comparing T-score values across the MMPI scales. These difficultieswere first discussed in detail by Colligan et al.(1983).In the development of the MMPI-2, uniform T-score transformation procedureswere used in order to provide equivalent T-score values across the clinical and con-tent scales (Tellegen & Ben-Porath, 1992). This same approach was used in the de-velopment of the MMPI-A. Uniform T-score values were developed for the clinicalscales by examining the distributions for scales 1,2, 3,4, 6,7, 8, and 9 for males andfemales separately. MMPI-A scales 5 and 0 were not included in the uniform T-scoreproceduresbecause these scales were derived differently than the other clinical scales,and the distribution ofscores on scales 5and 0are less skewed (i.e., more normally dis-tributed). A composite or averaged distribution ofraw scores was then created acrossthe eight basic scales for each gender, adjusting the distribution of each individualscale so that it would match the composite distribution.The purpose of developing acomposite distribution was to allow for the assignment of T-score conversion valuesfor each scale such that a given T-score value would convert to equivalent percentilevalues across each of these scales. Uniform T-score conversions were separately de-rived for the 15 content scales based on the distribution of scores for this group ofmeasures.Because uniform T-scoresrepresent compositelinearT-scores,thisprocedure servesto produce equivalent percentile values across scales for a given T-score. This pro-cedure, however, also maintains the underlying positive skew in the distributionof scores from these measures. Thus, uniform T-scores are generally similar to val-ues that would be obtained from linear T-scores (Edwards, Morrison, & Weissman,1993b). Nevertheless, differences in T-score transformation procedures, combinedwith marked differencesin mean raw score values produced by the Marks and Briggs(1972) and the MMPI-A (Butcher et al., 1992) normative sample, result in adolescentnorms that will often produce differences in overall elevation and profile configura-tion for a particular responsepattern. This topic isdiscussed in more detail in chapter 5in the section on codetype congruence issues. At this point, it is important to stressthat the clinician or researcher should not assume that the traditional MMPIand theMMPI-A will necessarily produce equivalent profiles, either in elevation or in code-type.Honaker examined the issue of equivalence between the MMPI and MMPI-2 inthe assessment of adults at a 1990 symposium. According to Honaker, the issue ofpsychometric equivalence is critically important because this factor determines, to alarge extent,the degree to which the vast research literature on the original instrumentmay be generalized to the revised and restandardized version. Honaker noted thatpsychometric theory and standards require four conditions to be met before the twoversions can be considered equivalent or parallel:1. Both should yield identical scores (mean scores, high-point codes, etc.).2. Both should yield the same distribution of scores.
  • 85. ADMINISTRATION AND SCORINGISSUES 713. The individual rank orderings produced by both should be identical (i.e., indi-viduals should be ranked on a given dimension in the same order based on testscores from each version).4. Scores generated from each version should correlateequally well with indepen-dent external criteria.In evaluating this issue, Honaker examined a sample of 101 adult psychiatric pa-tients who had received both the MMPI and the MMPI-2 in a counterbalanced,repeated-measures design. Findings indicated that the MMPI and the MMPI-2 didproduce parallel score dispersion and rank ordering of respondents but did notyield equivalent mean scores. MMPI-2 scores were consistently lower for scales F,2, 4, 8, 9, and 0. Further, the congruence of high-point codes between the MMPIand MMPI-2 was lower than that found for repeated administrations of the MMPIor the MMPI-2. These findings indicate that the MMPI and MMPI-2 are highly in-terrelated but not equivalent test instruments. A similar conclusion was supportedby research done by Archer and Gordon (1991a), who administered the MMPI-Aand MMPI to a sample of normal high school students. Findings from this studyindicate significant and pervasive elevation differences between T-scores producedby these two instruments, with MMPI-A scores significantlylower on most clinicalscales.Although it is quite clear that, using the criteria offered by Honaker (1990), theMMPI-A and MMPI are not psychometrically equivalent instruments, there is also asubstantial body of research literature that indicates that a high degree of congruenceis found between adolescent profiles generated from the original MMPI and fromthe MMPI-A. As we shall see in later chapters, this degree of congruence is taken tosupport the conclusion that much of the researchliterature developed for adolescentsusing the original test may be validly generalized to users of theMMPI-A.Deriving the Welsh CodeTwo major coding systems have been developed for MMPI profiles. The first, de-vised by Stark Hathaway (1947),was later modified and made more comprehensiveby George Welsh (1948). Because the Welsh system is more widely used than theHathaway system and allows for a more precise classification of profile features,thissystem is recommended for classification of adolescents MMPI-Aresponses. A com-plete description of both the Hathaway and Welsh systems, however, is contained insuch texts as Dahlstrom et al. (1972) and Friedman et al.(2001).The general function of profile coding is to summarize the most salient featuresof the profile without the loss of substantial information. These features include therange of elevation of scales and the pattern of relationships between the scales whenordered from highest to lowest elevation.The Welsh code requires that all standard clinical scales (designated by number)be arranged (left to right) in descending order of magnitude of T-score elevation.The traditional validity scales (L, F, and K) are then coded immediately to the rightof the clinical scales, again arranged from most to least elevated. The relative de-gree of elevation for any scale within the code is denoted by the following systemof symbols (as modified for the MMPI-A and described in the test manual for thisinstrument):
  • 86. 72 CHAPTER 3T-score Values Symbol120and above !110-119 !!100-109 **90-99 *80-8970-7965-69 +60-6450-59 /40-49 :30-39 #29 and below No symbol (scale is presentedto the right of the # symbol)In the Welsh coding system, the relevant symbol is placed to the immediate rightof the scale or scales related to that range of elevation. For example, if scale 2 has aT-score value of 98 and scale 4 has a T-score value of 92, the expression 24* wouldsymbolically represent this occurrence. Further, if two or more scales are within1 T-score point of each other, this occurrence is denoted by underlining all affectedscales. For example, if scale 2 was elevated at 53 and scale 3 was elevated at 52, theywould be denoted as follows: 23/. The following example, adapted from Friedmanet al. (2001), illustrates the Welsh coding system for the MMPI-A:Scales: L F K 1 2 3 4 5 6 7 8 9 0T-scores: 44 60 49 49 99 62 50 67 62 79 63 38 70Welsh Code: 2*"70 5+836-4/1:9## F-/KL:Several features ofthis illustration may be noted. Forexample, scales 3and 6both pro-duced an identical T-score value of62,and therefore by convention the scale identifiedby the lowest numerical value (i.e., scale 3) is presented first in the descending order.Additionally, scales 3, 6, and 8 vary by only one T-score value and therefore all threescales are underlined in the code. Finally, double quotation marks (") immediatelyfollow the asteric (*)after scale 2. This indicates that no MMPI scale produced valuesin the T-score range of 80 to 89, illustrating the convention that although no valuein this specific T-score range may occur, the appropriate symbol should neverthelessbe recorded in the code. Typically,most clinicians apply the Welsh code first to thestandard clinical scales and then to the validity scales. An example of the use ofWelshcoding for the MMPI-A is provided in the manual for this test instrument (Butcheret al., 1992).

  • 94. 4Validity Scales and ValidityAssessment InterpretationThere are several methods of assessing the technical validity of adolescents MMPI-A profiles. These methods have traditionally involved the individual and configuralinterpretation of standard validity scale findings and have often been extended toinclude an analysis of the overall MMPIbasic scale profile configuration for evidenceof atypical response set features. Additional methods of evaluating profile validityhave also been developed. These methods include the Test-Retest(TR) Index and theCarelessness (CLS) scale for the original form of the MMPI. For the MMPI-A, newvalidity measures were developed: the Variable Response Inconsistency (VRIN) andTrue Response Inconsistency (TRIN) scales and the F1 and F2 subscales.The inclusionof these four new validity scales at the beginning of the MMPI-Abasic scale profile(in conjunction with reordering L, F, and K to F, L, and K) is among the mostreadilyapparent changes associated with the revised instrument. In addition to discussingthese validity assessment tools, this chapter reviews a conceptual model developedby Roger Greene (1989a, 2000) for interpreting technical validity patterns. This modelemphasizes the distinction between response consistency and response accuracy ascomponents of technical validity.MMPI-A VALIDITY SCALESTraditional ValidityScales and Derivative SubscalesThe traditional validity scales (F, L, and K) originally developed by Hathaway andMcKinley were created to detect deviant test-taking attitudes and responses. De-termining the technical validity of the adolescents MMPI-A profiles is particularlyimportant because invalid profiles probably occur with a higher frequency in ado-lescent samples (these profiles result from problems related to response consistencyas well as response accuracy).Pogge, Stokes, Frank, Wong, and Harvey (1997), forexample, observed that although the MMPI-A has scales specifically designed toevaluate the effects of response styles on the disclosure of psychopathology, manyof the self-report instruments commonly used with adolescents (e.g., the SymptomChecklist-90-Revised and the Beck Depression Inventory) do not contain validityscales. Further, these researchers noted that some clinicians prefer to use observer80
  • 95. VALIDITY SCALES AND VALIDITY ASSESSMENT INTERPRETATION 81ratings of adolescents, rather than self-report data, as a means of attempting to mini-mize the possible effects of response styles. Pogge and his colleagues examined theseissues in a study of self-reportand therapist ratings of psychopathology for 235 ado-lescent psychiatric inpatients. All the participantsin this study completed three self-report rating scales, the MMPI, the SCL-90-R, and the BDI. The results from this studydemonstrated thatthe best predictionofself-report and therapist ratings ofadolescentsymptomatology was based on a prediction model incorporating individual scoresfrom clinical scales and from the validity scales L, F, and K. In fact, one third of theadolescent patients used in this study manifested clinical range elevations on at leastone of these three MMPIvalidity scales, underscoring the relatively high prevalenceof validity scale issues for this population. Pogge et al. concluded that their find-ings strongly indicate that the use of validity scales is central to the assessment ofpsychopathology among adolescents and that the use of clinician ratings does noteliminate self-presentation biases and does not serveas an adequate substitute for theevaluation ofself-reported psychopathology.Asresearchhas accumulatedon the stan-dard validity measures, however,Graham (2000) noted that we have come to view thetraditional validity scales as additional sources of inferences about the respondentsextratest behaviors. Thus, these validity scales provide information not only about thetechnical validity ofthe MMPIresponse pattern but also about concerning behavioralcorrelates or descriptors that are likely to apply to the respondent.The CannotSay (?) ScaleThe Cannot Say scale consists of the total number of items that a respondent failsto answer or answers in both the true and false directions. The Cannot Say scale isnot a formal MMPI scale because it does not have a consistent or fixed item pool.Profile sheets for the traditional MMPI have shown the Cannot Say scale as the firstin the series of standard validity scales on the profile grid. The MMPI-2and MMPI-Aprofile sheets, although still providing a space to record the raw score for the CannotSay scale,have deemphasized its role as a "scale" by placing it in the lower left portionof the profile sheet.Although severalstudieshave examinedthe characteristics ofCannot Sayvaluesinadult populations (as reviewed in Greene,1980,1989a, 1991,2000), very littleresearchhas been focused on this issue among adolescent respondents. Ball and Carroll (1960)examined correlates of the Cannot Say scores among 262 ninth-grade public schoolstudents in Kentucky.They reported that male respondents had a higher mean num-ber of Cannot Say responses than females. The items omitted by these adolescentstended to fall into broad categories, including statements not applicable to adoles-cents, religious items, items related to sexuality and bodily functions, and items thatrequired adolescents to make a decision concerning personal characteristics aboutwhich they were ambivalent. Similarly, Hathaway and Monachesi (1963) found 23items that were left unanswered by at least 2% of the male or female respondents intheir statewide Minnesota sample of normal adolescents. They reported that itemswith content related to religion and sex appeared to be the most frequently omitteditems for both boys and girls. Additionally,girls tended to leave a significantly largernumber of sex-related items unanswered.In general, findings on the original MMPI by Ball and Carroll (1960) and on theMMPI-A by Archer and Gordon (1991a) indicated a relationship between intellectualfunctioning/reading ability and Cannot Say scale scores. Ball and Carroll found noevidence of a relationship between Cannot Say scores and delinquent behaviors in

Archer and Gordon(1991a) found a significant relationship (r = —.10, p < .05) between the number ofunanswered MMPI-A items and adolescents reading abilities in a sample of 495ju-nior high and high school students. These findings suggest that adolescents failureto complete items may often be related to intellectual and reading limitationsratherthan oppositional and defiant characteristics.Table 4.1 provides information from Greene (1991) concerning the frequency ofomitted items for the original MMPIin psychiatricsamples of adults and adolescents.This table shows approximately equivalent rates of item omission between these twoage groups.Gottesman et al. (1987) reported that the mean Cannot Say scale value for normaladolescents in the Hathaway and Monachesi (1963) data set was roughly 3. Further,a raw score value of 5 to 6 converts to a T-score range of 70 to 80 in the Gottesmanet al. adolescent norms. It should be noted, however, that the Marks and Briggs(1972)adolescent norms for the traditional MMPIindicate that a Cannot Sayraw score valueof 30 converts to a T-score value of 50 for both male and female adolescents. ThisT-score conversion appears to be a continuation of the arbitraryassignment ofT-scorevalues to Cannot Say raw score values of 30 used by Hathaway and McKinley (1967)in the original adult MMPI norms. In both adolescent and adult samples, however,a raw score value of 30 on the Cannot Say scale occurs much less frequently than isimplied by the T = 50 value. The data from the MMPI-A normative sample indicatethat the mean raw score value for the Cannot Say scale is 1.01 for males (SD = 3.70)and .80for females (SD = 2.50).Greene (1991) identified traditional MMPIitems most frequently omitted in a sam-ple of 983 adolescent psychiatric patients. Of these 17 items, 10 were deleted in theformation of the MMPI-A, and 3 additional items underwent revision. The very lowCannot Say scale mean raw score values found for the MMPI-A normative samplesuggest that the MMPI-Aitem revision process may have been successful increating

Reprinted by permission.statements. Clopton and Neuringer (1977) demonstrated that random omissions of30 items or fewer from the traditional MMPI do not seriously distort MMPI profilefeatures when scored on adult norms. As previously noted, a substantial majority ofadolescents would be expected to omit fewer than 10 items on either the traditionalMMPI or the MMPI-A. Raw score values of 11to 30on the Cannot Say scale representsubstantially more omissions than is typical. This degree of item omission may beproduced by adolescents who have impaired reading ability or have life experiencelimitations that render some items meaningless or unanswerable. It is unlikely, how-ever, that this range of Cannot Say scale values will result in profile elevation or con-figuration distortions unless the omitted items are concentrated within a few scales.The Frequency (F) Scale and the FI and F2 SubscalesThe original MMPI F scale consisted of 64 items selected using the criterion that nomore than 10% of the Minnesota normative adult sample answered these items in thedeviant direction. As a result of this development procedure, the F scale was oftenreferred to as the Frequency or Infrequency scale. The F scale includes a varietyofitems related to strange or unusual experiences, thoughts, and sensations; paranoidideation; and antisocial attitudes and behaviors. The F scale on the original MMPIwas also one of the most problematic scales when applied to adolescent populations,because adolescents typically produced much higher F scale raw scores than adults.Significant F scale mean raw score differences between adolescent and adult respon-dents were consistently reported in both normal and clinical samples (e.g.,Archer,1984,1987b). Becauseofthe high F scalevalues typicalofadolescents, the use ofF scalevalidity criteria to assess the technical validity of teenagers MMPIprofiles was verycomplex and often ineffective. Interestingly, elevated F scale values have also beenfound in other populations or groups, when their responses are placed on standardnorms developed in the United States, including Chinese subjects from the PeoplesRepublic of China and Hong Kong (Cheung, Song, & Butcher, 1991).

Thus, F scaleitem endorsement patternshave been shown to be affected by both developmental and cultural factors.In the development of the MMPI-A, it was apparent that adolescents producedmarked elevations on the F scale because many of the F scale items had high ratesof endorsement in this age group. Specifically, 11 of the 60 F items that appear onthe MMPI-2 form for adults had item endorsement frequencies exceeding 20% inthe MMPI-A normative sample. For example, roughly 26% of both male and fe-male adolescents in the MMPI-Anormative sample responded true to the traditionalF scale abbreviated item "Feel need to injure self or others," and roughly 36%ofmales and 45%of females answered true to the abbreviated item "Like to daydream."Table 4.5provides the abbreviated item content and endorsement frequencies for the11F scale items most frequently endorsed by adolescents in the MMPI-A normativesample using the MMPI-TX experimental test form.The traditional F scale also contains several items that might be deemed offensivebecause statement content was related to religious beliefs (e.g., "Believe in God") orsexual attitudes and functioning (e.g., "Children should be taught about sex"). Basedon these observations, the F scale underwent a major revision in the development ofthe MMPI-A,leading to the creation of a new 66-item F scale, which is subdividedinto the FI and F2 subscales.The MMPI-A F scalewas createdby selectingitemsendorsed in a deviant directionby no more than 20%ofthe 805 boys and 815girlsin the MMPI-Anormative sample. Increating the MMPI-AF scale, 27items were deleted from the original F scalebecauseadolescents endorsement of these items exceeded the 20% criterion for selection orbecause the itemscontained content deemed inappropriate for inclusion in theMMPI-A. In addition, 12items that appeared in the original version of the MMPI but werenot traditionally scored on F were included in the MMPI-A F scale because theseitems met the 20%criterion rule. Finally, the MMPI-A F scale includes 17new itemsthat appear only on theMMPI-A.

Reprinted by permission.Table 4.6 provides five levels of interpretive suggestions for the MMPI-A F scale.Adolescents who produce marked or extreme elevations on the MMPI-A F scale maybe suffering from severe psychiatric illnesses, may be attempting to "fake-bad" oroverreport symptomatology, or may be engaging in a random response pattern eitherthrough conscious intent or as a result of inadequate reading ability. For example,Krakauer (1991) investigated the relationship between MMPI-A F scale elevationand reading ability in a sample of 495adolescents. She found that 11% of adolescentsscored below a sixth-grade reading level in the total sample. In a subsample of 231adolescents who produced F scale T-scorevalues equal to or greater than 65,however,the percentage of adolescents reading below the sixth-grade level increased to 18%.Similarly, a subsample of 120 adolescents who produced F scale T-score values of80 or greater yielded a poor-reader base rate of 24%.This increased to 29% in thesubsample of 68 adolescents who produced F scale T-score values of 90 or greater.The FI scale is a direct descendant of the original F scale and consists of 33 items,of which 24appeared in the original. The remaining nine FI items are new items thatdid not appear in the original instrument. All of the FI items occur among the first350items of the MMPI-Abooklet and thereforemay be used even when theMMPI-Ais given in the abbreviated format. The F2 scale also consists of 33 items, all of whichoccur after item 242 and 16 of which occur after item 350. The F2 scale consists pre-dominantly of items that appeared in the original MMPI (28 of the 33 F2items), butonly 12 of these items were scored on the F scale in the original instrument.

Each FI or F2 item, as part of the MMPI-A F scale, wasselected based on the criterion that fewer than 20%of normal adolescent subjects inthe MMPI-A normative sample endorsed the item in the scored or critical direction.The FI and F2 scales for the MMPI-A may be used in an interpretive strategysimilar to that employed for the F and Fb scales found in the MMPI-2 (Butcher et al.,1989). Specifically, the FI scale provides information concerning the validity of theadolescents responses to the basic MMPI-Ascales, whereas F2 provides information

Ifan adolescents F1 score is within the acceptable range, but the F2 score is extremelyelevated (T 90), use of a random response strategy during the latter half of theMMPI-A test is indicated. Under these conditions, it may be possible to interpret thedata from the standard scales while treating the content scale and supplementaryscale findings as invalid. If the F1 score exceeds the acceptable range, however, theentire protocol should be treated as invalid, and further interpretation should not beundertaken.Because the F1 and F2 scales are newly developed for the MMPI-A,research dataare currently fairly limited concerningthe optimal cutoff score for identifyinginvalidrecords. Berryet al. (1991) demonstrated the usefulness of the MMPI-2F and Fb scalesin detecting random responding in a college student sample. However, Archer andElkins (1999)reported that F,F1 ,and F2 were eachuseful when employed individuallyto identify random MMPI-A profiles, but the T-score difference between F1 and F2did not appear to be of practical assistance in this task. Further, Archer, Handel,Lynch, and Elkins (2002) found these F scales and subscales individually useful indetecting profiles with varying levels of random responding but noted that the F1-F2T-score difference was ineffective in this regard because "when the T-score differencecutoffs becamelargeenough to generateacceptablelevels ofpositive predictive power(probability an elevated score reflects a random protocol), so few random protocolswere found above that criterion score that test sensitivity was markedly low" (p.429).Archer et al. (2002) noted that a partial explanation of the failure of the F -F2 index toproduce useful results may lie in the tendency of the F1 subscale to produce higherT-score values than the F2 subscale under standard administration conditions as well asin most random response conditions. Table 4.6 provides some T-score interpretationguidelines for the MMPI-A F scale, and these T-score recommendations also appearto be applicable to the F1 and F2 subscales when interpreted as individual measures.Clinicians should be particularly cautious concerning validity inferences based on theobserved T-score differences that occur between the F1 and F2 subscales, however,given the limited usefulness of this index found in the research conducted thus far onthis issue.Two other frequency-related scales or indices have shown promise as means ofidentifying the overreporting of symptomatology among adolescents. Rogers, Hinds,and Sewell (1996) evaluated the clinical usefulness of three measures in assessing the
  • 102. 88 CHAPTER 4overreporting ofsymptomatology: the MMPI-A, the Structured Interview of ReportedSymptoms (SIRS),and the Screening Index ofMalingered Symptoms (SIMS).Employ-ing a within-subjects analog study of 53 dually diagnosed adolescents in residentialtreatment, Rogers and his colleagues found that the MMPI-Ascales F, F1, and F2werenot useful in identifying adolescents responses under honest versus feigning condi-tions, but they did observe that the raw score difference between the F and K scale(the F-K index) did appear promising using values equal to or greater than 20in thisclassification task. Further, the authors reported that the optimal combinationofdatafrom the SIRS and MMPI-A F-K index showed evidence of incremental validity inthis classification task. Although the results for the F-K index were promising in thisinvestigation, cross-validation of these findings is clearly required before conclusionscan be reached regarding their generalizability. McGrath et al. (2000) described thedevelopment and initial validation of the Infrequency-Psychopathologyscale (Fp-A)for the MMPI-A, which paralleled the development of a similar scale for theMMPI-2.Their findings demonstrated that the 40-item Fp-A scale appeared somewhat moreeffective than the F scale at discriminating between fake-bad and accuratereports ofpsychopathology for samples of normal adolescents and adolescents in an inpatienttreatment program and a sample of 140 high school students who were instructedto respond to the MMPI-A in a manner that simulated serious psychopathology.Although the authors conclude that there is tentative evidence that the Fp-A scalemay serve as a useful adjunct to the MMPI F scale as an indicator of overreporting,the evidence that the Fp-A scale provided incremental validity beyond the F scalein this study was relatively limited, and future research is needed before this scale isutilized in standard clinical practice with the MMPI-A.The Lie (L) ScaleThe L scale in the traditional MMPI consists of 15items that were originally selectedto identify individuals deliberately attempting to lie or to avoid answering the itempool in an open and honest manner. The L scale is keyed in the false direction for allitems and was created using a rational/intuitive identification of items. The MMPI-AL scale retains all but one item from the original measure and thus is a 14-itemscale.The traditional L scale item "Sometimes in elections I vote for men about whomI know very little" was deleted because of its limited relevance for many adolescents.Table4.8presents examples of the abbreviated items contained in the MMPI-A Lscale.The MMPI-A L scale covers a variety of content areas, including aggressive or hos-tile impulses, representing common human failings for the majority of individuals.Higher L scale values have been related to longer treatment duration for hospitalizedTABLE 4.8Sample Items From the LScaleItems scored if trueNoneExamples of items scored if false26.

In general, the clinicalcorrelatesof Lscaleelevations for adolescents appear to be similar to those in adult populations. Thus,moderate elevations, in the range of T-scorevalues of 60 to 65, are related to an em-phasis on conformity and the use of denial among adolescent respondents. Markedelevations in excess of a T-score value of 65 raise the possibility of a "nay-saying"response set or an unsophisticated attempt by a respondent to present personal char-acteristics in a favorable light and in a "saintly" manner. Because all L scale itemsare keyed in the false direction, this measure (in conjunction with the TRIN scalediscussed later in this chapter) serves as a valuable index in detecting all-true andall-false response patterns. Table 4.9presents a variety of interpretive suggestions forfour levels of L scale elevations on the MMPI-A.The Defensiveness (K) ScaleIn contrast to the F scale, the K scale did not undergo any item deletions in thedevelopment of the MMPI-A,and the wording of only two items was modified.Thus,the MMPI-A X scale consists of 30 items that were empirically selected to identifyindividuals who display significantdegrees ofpsychopathology but produce profilesthat are within normal limits (Meehl & Hathaway, 1946). Only one of these items isscored in the true direction. Table 4.10 provides examples of abbreviated items fromthe MMPI-A K scale.K scale item content is quite diverse and covers issues ranging from self-control tofamily and interpersonal relationships (Greene,1980,2000). Althoughthe K-correctionprocedure for basic scales 1, 4,7, 8, and 9 has become standard practice with adultrespondents, K-correctionwasnotused with adolescent profileson the original MMPIand is not used with the MMPI-A.Marks et al. (1974) presented three reasons why K-correction procedures should not be employed with adolescents. First, they noted thatK -correctionwas originally developed on a small sample of adult patients and "henceits applicability to adolescents is at best questionable" (p. 134).Second, they noted thatDahlstrom et al. (1972),as well as other authorities, have repeatedly cautioned againstthe use of K-weights with samples that differ significantly from those employed by

Finally, they citedprevious research using adolescent samples that indicated that adolescents MMPIscores produced a stronger relationship to external criteria without use of the K-correction procedure. This latter pattern was also reported by Weed, Ben-Porath, andButcher (1990) in MMPI data collected in adult samples and by Archer, Fontaine, andMcCrae (1998) in MMPI-2 results for adult psychiatric inpatients. These latter findingsraise questions concerning the usefulness of K-correction even in the interpretationof adult profiles.Alperin et al. (1996) derived experimental K-weights for the MMPI-A to determinethe degree to which the use of this correction procedure could improve testaccuracywhen weighting was based on results obtained in adolescent samples. Empiricallydetermined K-weights were systematically added to raw score values from the eightbasic scales (excludingMf and Si to optimally predict adolescents membership in theMMPI-A normative sample of 1,620 adolescents versus a clinicalsample of 122 ado-lescent psychiatric inpatients. Hit rate analyses were utilized to assess the degree towhich the K-corrected uniform T-scores resulted in improved classification accuracyin contrast to the standard MMPI-Anon-K-correctedadolescent norms. Results indi-cated that the use of a K-correction procedure for the MMPI-A did not result in anysystematic improvement in test accuracy in the classification task used in this study.The authors concluded that their findings did not support the clinical applicationofa K-correction procedure with the MMPI-A.In general, the K scale is unique (relative to the basic clinical scales) in that K scalemean raw score values for adolescents tend to be lower than that found for adultsamples. For example, the K scale mean raw score values for males and femalesin theMMPI-2 adult normative sample were 15.30 and 15.03, respectively (Butcher et al.,1989), whereas the normative values for males and females in the MMPI-Anormativesample were 12.7 and 11.5, respectively (Butcher et al., 1992). Although little researchhas been devoted to this issue, the available data indicate that K scale elevationsin adolescents may be related to the same clinical correlate patterns that have beenestablished for adult respondents. Thus, markedly low elevations on the K scale tendtobeproduced by adolescents who maybe consciously orunconsciously exaggeratingtheir degree of symptomatology in an attempt to fake-bad or as a "cry for help" inresponse to acute distress. Conversely, elevations on the K scale are often producedby adolescents who are defensive and who underreport psychological problems andsymptoms. Further, this latter group of adolescents often fail to perceive a need forpsychological treatment and attempt to deny psychological problems. They oftenhide behind a facade of adequate coping and adjustment. In both the adolescent and

Reprinted by permission.adult MMPIliteratures, high K scaleprofileshave been linked to a poor prognosis forpositive response to psychological intervention because of the respondents inabilityor refusal to cooperate with treatment efforts (Archer et al., 1979). Table 4.11 offersinterpretive guides for four elevation levels on the MMPI-A K scale.Traditional ValidityScaleConfigurationsA configuralapproach to validity scale interpretation may be applied to adolescentsMMPI-A profiles in a manner analogous to the interpretive suggestions for adults byFriedman et al. (2001), Graham (1987, 2000),Greene (1980, 2000), and Nichols (2001).The reordering of the traditional validity scales, however, in the MMPI-A (i.e., F, L,and K) requires us not to expect the validity scale configuralpatterns obtained withthe original MMPI.Figure 4.1provides a dimension along which to evaluate possibleMMPI-A validity scale configurations. The "most closed" validity configuration oc-curs when scales L and K are markedly elevated and scale F (including F1 and £2)is below a T-score of 50. The greater the degree of elevation manifested in scales Land K relative to the F scale and its subscales, the more the adolescent is attemptingto present an extremely favorable self-report that minimizes or denies the occurrenceof any psychological problems. This type of validity configuration would most likelybe encountered among adolescents who were involuntarily placed in treatment byparents or court officials. The utility of the MMPI-Avalidity scales of defensiveness(L and K) in detecting underreporting of symptoms on the MMPI-Awas recently in-vestigated in clinical and community samples of adolescents by Baer, Ballenger, andKroll (1998).Half of the subjects in each of the samples were instructed to completethe MMPI-A in such a manner as to create an impression of excellent psychologicaladjustment and functioning.The remaining respondents completed the MMPI-A un-der standard instructions. The traditional Land K scales were found to be moderatelyeffective in discriminating standard from underreported profiles, with correct classi-fication rates ranging from 68%to 84%.Both the community and clinical samplesofadolescentsinstructed tounderreport symptomatology produced significantly higher

At the oppositeex-treme is the "most open" profile configurationcharacterized by elevated F scale andsubscale values and L and K scaleT-scorevalues below 50.As the elevation differencebetween the F scale and the L and K scales becomes more pronounced or extreme,itis increasingly likely that the adolescent is exaggerating symptomatology or psycho-logical problems as a cry for help. This pattern may reflect a conscious or unconsciouseffort to overreport symptomatology.On the original form of the MMPI, configural approaches to validity scale inter-pretation were rendered complex because adolescents F scale values were typicallyhigher than those found for adults, and thus interpretiveinferencesneeded to be ad-justed accordingly. The "most open" profile type was very frequently encounteredfor adolescents on the original instrument, whereas the "most closed" profile typeoccurred infrequently. Additionally, related to the issue of high F scale elevations,the F-K index was not useful when employed with adolescents (Archer, 1987b).Be-cause of the major revision that occurred in creating the MMPI-A F scale, validityscale configuration patterns have become correspondingly more useful for this in-strument. For example, Stein, Graham, and Williams (1995) found the F-K index assuccessful as the F scale in detecting faked profiles on the MMPI-A, and, as notedearlier, Rogers et al. (1996) reported that the F-K index was more effective than theMMPI-A F scale and subscales in detecting overreported profiles. However, untilmore research has been conducted using the F-Kindex with adolescent samples, thestandard clinical use of this index is not advised. This is consistent with the recom-mendation by Rothkeet al. (1994) that separate F-Kguidelines should be establishedfor male and female subjectsin specific populations or diagnostic groups. In addition,Baer, Wetter,and Berry (1992)and Bagby, Rogers, Buis,and Kalemba (1994) noted that

Both the VRIN and TRIN scalesprovide data concerning an individuals tendency to respond to MMPI-A items in aconsistent manner. The VRIN scale consists of 50 pairs of items with either similar oropposite content. Each time an adolescent answers an item pair inconsistently, oneraw score point is added to the VRIN scale score. Table 4.12 provides illustrationsofVRIN scaleitems. As shown in this table, the contentof the item pairs determines theresponse combinationthat would result in a point added to the VRIN total. For someitem pairs, two true responses are scored; for other combinations,two false responsesare scored; and for others, a combination of true and false responses produces aninconsistent response pattern, resulting in a point added to the raw score value. TheVRIN findings can serveas awarningthat an adolescenthas responded to theMMPI-Ain an indiscriminate and random manner. For example, Berry et al. (1992) and Berryet al. (1991) demonstrated the sensitivity of the MMPI-2 VRIN scale to the presenceof random responding in college student samples. Elevated VRIN scale values canalso be used to support the inference that an elevation on the F scale is likely toreflect carelessness or a random response pattern. Illustrating this point, Wetter,Baer,Berry, Smith, and Larsen (1992) found that both random responses and malingeredresponses produced elevations on the MMPI-2 F scale in a college student samplebut that elevated VRIN scale scores resulted solely from random response patterns.Thus, a high VRIN score combined with a high F scale score strongly suggests thepossibility of a random response pattern. It should be noted, however, that VRINT-score values within the acceptable range do not necessarily imply that anMMPI-Aprofile is subject to valid interpretation. Although VRIN scale values are related toinferences concerning the consistency of an adolescents response pattern, findings
  • 108. 94 CHAPTER 4from this scale do not permit judgments concerning the accuracy of the subjectsresponses. The distinction between accuracy and consistency as subcomponents ofvalidity assessment is discussed later in this chapter.The effectiveness of the MMPI-A VRIN scale in adolescent populations has beenthe focus of several relatively recent studies. Baer, Ballenger,Berry, and Wetter (1997),for example, examined random responding on the MMPI-A in a sample of 106 normaladolescents. Participants were asked to report on the frequency, location,and reasonfor any random responses that occurred during the standard administration of theMMPI-A, and relationships between self-reported random responding and validityscales scores were examined, including the F, F1, F2, and VRIN scales. In addition,participants were assigned to groups that varied in the extent of random responding(0%, 25%, 50%, 75%, or 100% random). Findings indicated that most adolescentsacknowledged one or more random responses during the standard administrationprocess, and the number of self-reported random responses was significantly corre-lated with the F scale. Further, scores on the F and VRIN scales were effective indiscriminating standard protocols from protocols with various levels of randomness.The authors concluded that their study provided strong support for the utilityofthe VRIN scale because this scale is designed to be sensitive to random respondingbut unlike the F scale does not typically elevate under conditions of symptom over-reporting. Archer and Elkins (1999) followed up this line of research by evaluatingthe utility of MMPI-A validity scales in detecting differences in response patternsbetween protocols produced by 354 adolescents in clinical settings and a group of354 randomly produced MMPI-A protocols. Results indicated that the MMPI-A va-lidity scales F, F1 , F2, and VRIN all appeared to be useful in correctly identifyingprotocols from actual clinical participants versus randomly generated response pat-terns. Further, it was noted that the optimal MMPI-A scale cutoffs for these validityscales were largely consistent with the interpretive recommendations provided in theMMPI-A test manual (Butcher et al., 1992), that is, T 80 on VRIN and T 90 onF, F1, F2. Archer et al. (2002) extended this methodology by examining the abilityofthe MMPI-A validity scales to detect varying degrees of protocol randomness. Theycompared MMPI-A protocols resulting from the administration of the instrument to100 adolescent inpatients under standard conditions and 100 protocols containingvarying degrees of computer-generated random responses. In general, the overallclassification accuracy reported by Archer et al. (2002) was highly consistent with theoverall classificationaccuracy reported by Archer and Elkins (1999) and by Baer et al.(1997). T-score values for the VRIN scale consistently climbed as increasing levelsof randomness were introduced into the protocols, with a T-score value 80 on theVRIN scale generally functioning as a useful cutoff across varying levels of randomresponding. However, the VRIN scale was more effective in distinguishing standardlyadministered protocols from protocols that contained larger proportions of randomresponding. No MMPI-A validity scale was particularly effective in detecting par-tially random responding that involves less than half of the items in the second halfof the test booklet. In general, the MMPI-A VRIN scale has demonstrated sufficienteffectiveness to serve as a model for similar attempts to detect random responding onother test instruments. For example, a variable response inconsistency scale has beendeveloped for the Jesness Inventory, a self-report instrument designed for use withdelinquent boys and girls aged 8 through 18(Pinsoneault,1997,1999).The TRIN scale for the MMPI-A, like its counterpart in the MMPI-2,was devel-oped to detect an individuals tendency to indiscriminately respond to items as eithertrue (acquiescence response set) or false (nay-saying) regardless of item content.This

In the computer scoringof the MMPI-A provided by Pearson Assessments, the direction of deviation is indi-cated by a "T" or "F" followingthe T-score assigned to the TRIN scale. For example,80 T would indicate inconsistency in the true-response direction, whereas 80F wouldrepresent an equal magnitude of inconsistency in the direction of false responding.Table 4.13 provides examples of TRIN items. As shown in Table 4.13, true responsesto some item pairs and false responses to other item pairs result in scores on the TRINscale. TRIN scores provide information on the degree to which an adolescent hastended to employ an acquiescent or nay-saying response style. As noted by Greene(2000), however, these scores should not be used to determine whether an adolescenthas endorsed MMPI-A items in a random manner. As shown later in this chapter inthe example of a random profile, the TRINscale may often produce acceptable T-scorevalues under a random response set condition. The specificformula for TRINscoring,as provided in the MMPI-Amanual (Butcheret al, 1992, 2001), is as follows:1. For each of the followingresponse pairs add one point:14 T-424 T 119 T-184 T37 T-168 T 146 T-167 T60 T-121 T 242 T-260 T62 T-360 T 264 T-331 T63 T-120 T 304 T-335 T70 T-223 T 355 T-367 T71 T-283 T 463 T-476 T95 T-294 T2. For each of the following response patterns subtract one point:46 F-475 F 128 F-465 F53 F-91 F 158 F-288 F63 F-120 F 245 F-257 F71 F-283 F 304 F-335 F82 F-316 F3. Then add 9 points to the total raw score.
  • 110. 96 CHAPTER 4Both TRIN and VRIN are new MMPI-A scales, and limited informationis currentlyavailable concerning the characteristics of these measures in adolescent samples. Be-cause both scales include items beyond item 350, the full MMPI-A must be admin-istered to score TRIN or VRIN. The followingrough guidelines in interpreting thesescales are tentatively recommended:VRIN T-scores of 70-79 indicate marginal levels of response inconsistency.VRIN T-scores 80 indicate unacceptable levels of response inconsistency.TRIN T-scores of 70-79 indicate marginal levels of response inconsistency.TRIN T-scores 80 indicate unacceptable levels of response inconsistency.Inconsistent item endorsement patterns for adolescents may be related to inad-equate reading ability, limited intellectual ability, active noncompliance or test re-sistance, or thought disorganization related to substance abuse-induced toxicity oractive psychosis.The Items-Easy (Ie) and Items-Difficult (Id) ScalesThe evaluation ofresponse consistency among adolescents administered the MMPI-Amay include the use of the Items-Easy (Ie) and Items-Difficult (Id) scales developedby Krakauer, Archer, and Gordon (1993).These scales were designed to assess or esti-mate the degree to which reading comprehension deficiencies may be responsible forinconsistent item endorsement patterns on the MMPI-A.Using a combinationof twocriteria, two 13-item scales were empirically created for this purpose. The 13itemsselected for the Ie scale were evaluated objectively on three standardized readingmeasures and were shown to be among those MMPI-A items exhibiting relativelylow levels of reading difficulty. In addition, these items did not produce significantcorrelations with subjects scores on a measure of reading ability. In contrast, the13 items selected for the Id scale were shown to be among those with a higher levelof reading difficulty, and each exhibited a significantinverse correlation with readinglevel scores. Items on both scales were additionally subjected to the requirement thatall items must have a critical-directionendorsement frequency of 35% or less in theMMPI-A normative sample of 1,620 adolescents. Based on these procedures, itemswere selected in such a way that the two scales had the same number of items andthe same percentage of items keyed true and false. Additionally, the two scales wereroughly equivalent in terms ofmean item endorsement frequencyand the percentageof items loading on each of the basic clinical scales. Preliminary research supportedthe hypothesis that adequate readers would endorse the items in the le and Id scaleswith approximately equal frequency whereas deficient readers would endorse moreId scale items than le scale items. Krakauer et al. (1993) concluded that these scalesheld the potential to assist clinicians in detecting possible reading limitations, partic-ularly for those subjects who produced significant elevations on the VRIN scale andthe F scale. For example, high VRIN scale scores in combination with a small Id-Iedifference score could be illustrative ofa random response pattern produced by a non-cooperativeteenager. In contrast, a high VRIN scale score in combination with a higherendorsement rate for Id items than Ie items might be reflective of a response patternproduced by a cooperative subject who simply did not have adequate readingabilityto understand many of the MMPI-Aitems. Krakaueret al. (1993) cautionedthat theIeand Id scales had not undergone clinical research evaluation, however, and suggested
  • 111. VALIDITY SCALES AND VALIDITY ASSESSMENT INTERPRETATION 97that these measures be employed only in research investigations. Unfortunately, nopublished studies have appeared on these scales over the past decade, and their useremains restricted to research investigations at this time. The item composition of theMMPI-A Ie scale is as follows:Scored true: 28, 66, 88, 93,159, 344, 345, 347,348Scored false: 77,122, 324,346The item composition of the Id scale is as follows:Scored true: 30,101,183, 219, 250, 273, 276, 349, 350Scored false: 48, 89,98,120EFFECTS OF RESPONSE SETS ON STANDARDSCALESGraham (2000) described the characteristics of MMPI-2 profiles that are generatedby adults based on systematic response sets such as all-true, all-false, and randompatterns, and Graham, Watts,and Timbrook (1991) described MMPI-2fake-good andfake-bad profiles. Similar response set data for adolescents on the original test instru-ment were presented by Archer, Gordon, and Kirchner (1987) and summarized forthe MMPI-Aby Archer and Krishnamurthy (2002) and Butcher and Williams (2000).Archer and Krishnamurthy (2002) noted that adolescents employing all-true and all-false response sets on the MMPI-Aare easily detected and that the extreme validityscale profile features are similar to those produced by their adult counterparts. Addi-tionally, the fake-bador overreporting response set found for adolescents is relativelyeasy to identify based on the occurrenceof an extremely elevated F scale combinedwith clinical-range elevations on all clinical scales (excluding Mfand Si. Incontrast,adolescents production of random response sets and particularly on fake-good orunderreporting response sets were more difficult to detect on the MMPI-A. The fol-lowing section provides a summary of the effects of a variety of response sets on theMMPI-A.All-TrueThe all-true response pattern is indicated by extremely low scores on scales L and Kand markedly elevated scores (T > 90) on scales F, F1, and F2. The male and femaleall-true profiles on MMPI-A norms are presented in Fig. 4.2. The raw score valuefor TRIN (raw score = 24) clearly indicates response inconsistency (in particular, anextreme yea-saying response style), whereas the VRIN value (raw score = 5)is withinacceptable limits. Inaddition to the extreme "most open" validity scale pattern formedby scales F1 , F2 F, L, and K, there is a very noticeable positive or psychotic slope tothe profile, with elevations on scales 6, 7, 8, and 9. These characteristics are similarto those found for all-true response patterns among adolescents on the original formof the MMPI (Archer,1989).Figure 4.3shows the content scale and supplementary scale profiles for the all-trueresponse pattern for males and females. Because the majority of items in the contentscales arekeyed inthe true direction, these profiles exhibit very elevated T-score valuesfor most content scales.

All-false MMPI-A response patterns for males and females(TRINT-score = 101Ffor males and 110F forfemales).All-FalseThe profiles shown in Fig. 4.4 will be produced if adolescents respond false to allMMPI-A items. The TRIN raw score value is zero (T > 100) and the VRIN raw scorevalue is 4.The TRINvalue indicates response inconsistency (in particular, an extremenay-saying response style). In addition, the F1 values produce marginally elevatedT-scores, whereas the F2 and F T-scores fall within normal limits. The all-false profilesare characterized by extreme elevations on validity scales L and K and on the firstthree clinical scales of the MMPI,which are frequentlyreferredto as the neurotic triad.Theclinicalscaleprofiles haveadistinctivenegativeslope; thatis,scalevalues decreaseas the numerical scale designations increase. Further, these profiles are similar to theall-false profiles for adolescents on the original MMPIreported by Archer et al.(1987)and for adults on the MMPI-2 reported by Graham (2000). The characteristic profilefeatures ofboth the all-true and the all-false patterns clearly indicate profile invalidity.It should be clearly noted, however, that these deviant response sets should typicallybe detected by the inspection of the completed answer form prior to the profiling ofresponse features.Figure 4.5 shows the content and supplementary scale profiles associated with anall-false pattern. Because all content scales except Health Concerns (A-hea) and LowAspirations (A-las) are composed of items predominantly keyed in the true direction,an all-false response set produces low T-scores for these scales. In contrast, the Re-pression (R) scale is composed of items exclusively keyed in the false direction andtherefore produces a very elevated T-score value under this response set.
  • 114. 100 CHAPTER 4Random Response SetsAn adolescent may also respond to MMPI-A items randomly. The profiles resultingfrom equal numbers of true and false item endorsements on each MMPI-Abasic scale(i.e., the effect of an infinite number of random sorts) are presented in Fig.4.6.Consistent with the findings for adolescents on the original test instrument (Archeret al., 1987), random MMPI-Aprofiles are more difficult to detect than other responsesets. The MMPI-Avalidity scale VRIN is a useful indicatorof random response sets inadolescents. The TRIN scale, however, may often produce acceptable T-scorevaluesunder a random response set condition. The random profileis also characterizedby ahighly unusual validity scaleconfiguration in which clinical-range elevationsonscalesF, F1 , and F2 are accompanied by a clinical-range L scale elevation. The actualpro-file characteristics of a random response set will vary substantially depending on theparticular approach used to randomize the response pattern. The profile character-istics will also vary quite markedly depending on the degree of randomness in theprofile, and Archer et al. (2002) demonstrated that "partially random" protocols maybe difficult or impossible to detect through the examination of validity scale results.Random response patterns should always be considered when an adolescent com-pletes the MMPI-A too quickly (i.e., in less than 40minutes).Figure 4.7 shows the effects of a totally random response pattern on theMMPI-Acontent and supplementary scales. Similar to the corresponding basic scale profiles,even these profiles are relatively difficult to detect based on shape and elevationfeatures.FIF. 4.5.

  • 116. 102 CHAPTER 4(Fake-Good) UnderreportingAnother response set issue concerns the characteristics of MMPI-A profiles pro-duced by adolescents who distort the accuracy of their responses. Adolescents mayfake-good, or underreport problems on the MMPI-A,or they may fake-bad,complet-ing the MMPI-A in a manner that overreports symptomatology. Because these typesof profiles may be produced by individuals who consciously or unconsciously distorttheir responses, Greene (2000) and Archer and Krishnamurthy (2002) emphasizedthe use of the terms underreporting and overreporting to describe these response sets.Graham (2000)used the terms positive self-presentation and negative self-presentation todescribe these distortions in a subjects test responses, and Friedman et al. (2001)usedthe terms self-favorable and self-unfavorable.Studies with adult psychiatric patients have found that the ability to simulatea normal profile is significantly related to a favorable treatment outcome amongschizophrenics (Newmark, Gentry, Whitt, McKee, &Wicker, 1983) and across psychi-atric diagnoses (Grayson & Olinger, 1957). Additionally, Bonfilio and Lyman (1981)investigated the ability of college students to simulate the profile of "well-adjusted"peers.Results from this study indicated that simulations produced by college studentsclassified as neurotic, normal, and psychopathic based on actual MMPIs administeredunder normal instructions were essentially within normal limits. Simulated profilesproduced by psychotic or hypomanic college students, however, contained clearlypathological or clinical-range features.Graham, Watts,et al. (1991) presented MMPI-2fake-good response features generated by college students who were administeredthe MMPI with instructions to respond as they would if they were applying for ahighly valued job. The clearest indication of a fake-good profile in these data wasthe occurrence of the "most closed" validity scale configuration, in which scales Land K show marked elevations (in this study, the elevations in L were especiallyhigh). Baer, Wetter,and Berry (1995) examined the effects of two levels of informationabout the MMPI-2 validity scales on the ability of college students to underreportsymptomatology. Findings indicated that the MMPI-2 standard validity scales, in-cluding L and K, were effective in accuratelyidentifyinguncoached fakers. However,these scales were far less effective in discriminating standard subjects from coachedsubjects given either detailed or general information concerning the operation of theMMPI-2 validity scales. These findings suggest that providing information about thepresence and functions of validity scales may enable some subjects to distort theirresponses on the MMPI-2 (and potentially the MMPI-A) in a way that effectivelyevades detection. Finally, Bagby, Rogers, and Buis (1994) examined the effectivenessof various MMPI-2 validity scales and indices in the detection of malingering andfaking-good in samples consisting of 165college students and 173forensicinpatients.Although several validity indicators appear to be moderately effective at detectingfake-bad profiles, only the F-K index and the Subtle-Obvious index appeared to haveutility in the detection of efforts to underreport symptomatology.To investigate fake-good profiles in an adolescent sample, Archer et al. (1987) ad-ministered the original form of the MMPI to a group of 22 adolescents (mean age =14.76 years) in an inpatient psychiatric setting. Ten of these adolescents were femaleand 12were male. These adolescents were individually administered the MMPI withthe following instructions:We would like you to respond to the MMPI as you believe a well-adjusted teenagerwould who is not experiencing emotional or psychological problems. By well-adjusted,we mean an adolescent who is doing well and is comfortable in school, at home, and withtheir peers. As you read the items in the MMPI, please respond to them as you believe a
  • 117. VALIDITY SCALES AND VALIDITY ASSESSMENT INTERPRETATION 103FIG. 4.8. Fake-good MMPI-A profiles.well-adjusted adolescent would who is not in need of psychiatric counseling, and whois relatively happy and comfortable, (pp. 508-509)As noted by Archer et al. (1987),two distinct profilegroups emerged in response tothis fake-goodinstructional set. Eightadolescents produced profilestermed ineffective,because they were very poor simulations of a normal profile (i.e., one or more clinicalscales were elevated abovea T-score valueof 70).In contrast,a group of 14adolescentswere able to produce normal(effective) profiles in that noneofthe clinicalscalevalueswere elevated within clinical ranges. In general, adolescents in the effective grouptended to be older, have less severe diagnoses, and produce less elevated profilesunder the standard administration conditions.These data were reanalyzed using information that allows for T-score conversionsbetween the MMPI and the MMPI-A (this information is contained in the MMPI-A manual and reproduced in Appendix D). Figure 4.8 presents the correspondingMMPI-A T-score profiles for the effective and ineffective groups under fake-goodinstructions.Thedata indicate avalidity scaleconfiguration forthe effective group characterizedby elevations on scales L, F, and K, that are generally within the acceptable ranges.Clinical scalevalues present a "hypernormal" configuration,with T-scoresat or below50on most clinical scales.Therefore,the mean fake-goodprofilefor the effective groupwould be difficult to distinguish from the responses of a somewhat guarded anddefensive normaladolescentwithout significant psychiatricproblems. The followingguidelines, however, should serve to improve screeningfor adolescentswho attemptto fake-good on the MMPI-A:
  • 118. 104 CHAPTER 41. Elevations on validity scales L and K are equal to or greater than 65.2. All clinical scale T-score values are less than or equal to 60but are produced byan adolescent with known or established psychopathology.Over-reporting (Fake-Bad)The ability of normal adults to simulate psychopathology, or to fake-bad, has beeninvestigated by numerous researchers, including Anthony (1976), Exner, McDowell,Pabst, Stackman, and Kirk (1963), Gough (1947, 1954), Lanyon (1967), and Meehland Hathaway (1946). Results have consistently shown that adults fail to accuratelysimulate the types of symptomatology typically reported by psychiatric patients. Ingeneral, normals tend to overreport psychopathology on the MMPIin an exaggeratedand nonspecific manner that is easily detected as a fake-bad attempt (Dahlstrom et al.,1975; Greene, 1980,2000). Graham, Watts, et al. (1991) requested male and female col-lege students to take the MMPI-2with instructions to present themselves as ifthey had"serious psychological or emotional problems" (p. 267).The fake-badprofiles for bothmen and women were characterized by highly elevated F scale values and clinical-range elevations on all standard clinical scales except Mf and Si. Rogers, Sewell, andUstad (1995)investigated the MMPI-2characteristicsof 42 chronicpsychiatric outpa-tients who were administered the MMPI-2under standard (honest)and fake-bad in-structional sets. Whereas subjects under both conditions produced relatively elevatedscores on the F and F,scales, the use of an F raw score greater than 29 was found toaccurately discriminate between protocols derived under the two administration con-ditions. Rogers, Sewell, and Salekin (1994)recently provided ameta-analysis of severalMMPI-2 validity scales or indices potentially useful in the evaluation of faking-bador overreporting psychopathology. Of these measures, the authors reported that scaleF, the F-Kindex, and the Obvious-Subtle subscales showed particularly strong effectsand demonstrated effectiveness across a variety of samples. Rogerset al. (1996) specif-ically evaluated the MMPI-Avalidity scales in terms of the capacityof these scales todetect adolescents efforts to overreport symptomatology and concluded that theF-Kindex appeared most effective and promising with this population.A number of investigations have examined the effects of providing symptom ordiagnostic information on subjects ability to effectively fake-bad or overreport symp-tomatology on the MMPI-2. Rogers, Bagby, and Chakraborty (1993) compared theMMPI-2 profiles of subjects who had been provided information or coached on thesymptoms of schizophrenia, coached on strategies used to detect faking-bad effortson the MMPI-2, coached on both symptoms and detection strategies, or were un-coached. These authors reported that knowledge concerning the operation and useof MMPI-2 scales and indices used to detect malingering was sufficient to allow ap-proximately one third of their sample to elude detection. In contrast, knowledge con-cerning schizophrenia appeared to be less useful to simulators attempting to feign aschizophrenic disorder "of sufficient severity as to warrant hospitalization" (p. 218).Wetter, Baer, Berry, Robison, and Sumpter (1993) provided two groups of normaladults with information concerning the symptoms of posttraumatic stress disorderand paranoid schizophrenia and instructed these subjects to simulate these disorderson the MMPI-2, with monetary rewards offered for successful simulation. Wetter andher colleagues concluded that providing symptom information about a psychologicaldisorder did not enable fakers to avoid detection. Their fake-bad groups producedlower scores on K and higher scores on F and the 10clinicalscales than actualpatientgroups. A variety of other investigations have examined the effects ofprovidingsymp-tom information on borderline personality disorder (Wetter,Baer, Berry, & Reynolds,
  • 119. VALIDITY SCALES AND VALIDITY ASSESSMENT INTERPRETATION 1051994), somatoform disorder and paranoid psychosis (Sivec, Lynn, & Garske, 1994),and closed head injury (Lamb, Berry, Wetter, & Baer, 1994). In general, the resultsof these investigations indicate that the effects of symptom coaching are relativelylimited and that the MMPI-2validity scales are generally capable of accurately iden-tifying malingered profiles. Illustrating this latter point, Bagby et al. (1997) reportedthat psychiatric residents and clinical psychology graduate students, who presum-ably have considerable information about psychopathology and psychological test-ing, were easily detected when they attempted to feign schizophrenia on theMMPI-2.Further, Storm and Graham (1998) evaluated the scores of students who were in-structed to simulate general psychopathology on the MMPI-2 after being providedwith information concerning the validity scales in contrast to patients who took theMMPI-2 under standard instructions. Scores on the MMPI-2 F and F(p) scales wereeffective in discriminating students simulating psychopathology from actualpatients,and the F(p) scale was found to be particularly effective in this regard.Given the plethora of studies recently emerging in this area, Ben-Porath (1994)focused on the ethical issues surrounding research in which investigators attemptto evaluate the effectiveness of various coping strategies for eluding the MMPI-2validity scales. Ben-Porathnoted that the specific coping strategies detailed in thesepublications could be used in forensic settings to help individuals fake MMPI profilesin a manner that successfully avoids detection. Thus, this body of literature could bemisused in a manner that compromises the integrity of the instrument. Underscoringthis area of concern, Wetter and Corrigan (1995) recently conducted a survey of 70attorneys and 150law students that indicated that almost 50%of the attorneys andover 33%of the law students believed that their clients should typically or always beinformed of validity scales on psychological tests.Research by Archer et al. (1987)investigated the characteristicsof fake-badprofilesamong normal adolescents. The original form of the MMPI was administered to agroup of 94 public high school students in four psychology classes, with the subjectsranging in age from 14 to 18 years and roughly equally divided in terms of genderand ethnicbackground (Black-White). Subjects were administered the MMPIwith thefollowing instructions:We would like you to respond to the MMPI as you believe you would if you wereexperiencingseriousemotionalorpsychologicalproblems.By serious problems,wemeanproblems that were severe enough that hospitalization for treatment would be necessary.As you read the items in the MMPI, please respond to them as if you were seriouslydisturbed and in need of hospital treatment for psychiatric care. (p. 508)The mean profile produced by this group showed a grossly exaggerated picture ofsymptomatology,including a veryelevated mean F scalevalue ofT= 130 and clinical-range elevations on all MMPI clinical scales except Mf and Si. Data from the fake-badadministration were reprofiled using the values provided in Appendix D of this textto derive MMPI-Anorm-based T-score values. Figure 4.9, plotted on these MMPI-Anorms, presents this fake-bad profile (the TRIN and VRIN scales cannot be derivedfrom these data). Consistent with the findings by Archer et al. (1987) for the originalMMPI and the MMPI-2 results reported by Graham, Watts, et al. (1991) for collegestudents, the fake-bad profile on the MMPI-Ais characterized by extremely elevatedF scale T-score values and multiple clinical-range elevations on the standard clinicalscales. These data indicate that adolescents will probably encounter substantial dif-ficulty in successfully simulating psychiatric illness on the MMPI-A.The TRIN andVRIN raw score values for fake-bad and fake-good profiles, although not shown in
  • 120. 106 CHAPTER 4Figs. 4.8and 4.9, would typically be within acceptable limits for response consistency,underscoring the difference between response inconsistency and response accuracy.Greene (1989a, 2000) noted that individuals who attempt to underreport or overre-port on the MMPI often produce highly consistent (although inaccurateand invalid)response patterns.The F scale and clinical scale criteria summarized here should serve to effectivelyscreen for most adolescents who attempt to fake-bad on the MMPI-A:1. F scale raw score value > 90.2. Presence of a floating profile characterized by clinical scale elevations withinthe clinical ranges (shaded zone or higher), with the exception of Mf andSi scale values.A CONCEPTUAL MODEL FOR VALIDITY ASSESSMENTGreene (1989a, 2000) presented a conceptual approach or model for understandingvalidity assessment issues, as well as a number of empirical criteria through whichto assess the validity of MMPI profiles. Figure 4.10 provides an overview of Greenesmodel.Greene emphasized the use of sequential steps or stages in the validity assessmentprocess. The first stage involves determining the number of omitted items (i.e., theCannot Say scale raw score value), with the omission of more than 25 items relatedto invalid profiles potentially requiring test readministration. Greene noted that ex-cessive item omissions not only may reflect characteristicsof the respondent but canalso serve as a signal of problems in the MMPI administration process.FIG. 4.9. Fake-bad MMPI-A profile.

Published by Allyn & Bacon, Boston,MA. Copyright © 2000 by Pearson Education. Adapted by permission of the publisher.)Consistency of Item EndorsementThe next step in evaluatingthe validity of the responses involves assessing the con-sistency of item endorsement. As noted by Greene (2000):Consistency of item endorsement verifies that the client has endorsed the items in a re-liable manner for this specific administration of the MMPI-2. It is necessary to ensurethat the patient has endorsed the items consistently before it is appropriate to deter-mine the accuracy with which the client has endorsed the items The consistencyof item endorsement (may be conceptualized) as being independent of or irrelevantto item content, whereas the accuracyofitem endorsement is dependent on or relevant toitem content, (p.51)On the original version of the MMPI,item endorsement consistency has been mea-sured by the use of the Test-Retest (TR)Index (Buechley & Ball, 1952) and the Care-lessness (CIS) scale developed by Greene (1978).The TR Index and the CLS scale are not applicable to the MMPI-Abecause of thechanges in item content in the creation of this instrument. In particular, the repeatedpresentation of 16 items in the original MMPI has been eliminated in the MMPI-A.Nevertheless, as previously noted, there are new scales available on the MMPI-Atoevaluate response consistency.The TRIN and VRIN scales are descendants of GreenesCLS scale and provide substantial information concerning the adolescents responseconsistency. Further, the comparison of FI and F2values may allow for the detectionof inconsistent response patterns that occur during the latter stages of the MMPI-A
  • 122. 108 CHAPTER 4test booklet, although the effectiveness ofthis comparison does not appear supportedby the research findings of Archer et al. (2002).Regardless of the cause, substantial inconsistency renders the MMPI-A profile in-valid, in which case further profile interpretation should not be undertaken. Greenesmodel of validity assessment indicates that unacceptably high levels of response in-consistency require readministration of the MMPI in order to obtain interpretableclinical data.Accuracy of ItemEndorsementThe next step in the process of assessing MMPIor MMPI-A validityis to derive an esti-mate ofitem endorsement accuracy.Greene (2000) noted several assumptions relevantto this stage ofvalidity assessment. First, overreporting and underreporting representa continuum, and any particular respondent may be placed at some point along thisdimension. Second, attempts to overreport and underreport symptomatology tendto be generalized rather than specific. For example, adults who underreport tend todeny the presence of any type or dimension of psychopathology, and individuals en-gaged in overreporting tend to endorse psychopathology related to a wide varietyof mental disorders. Third, Greene pointed out that the occurrence of overreportingor underreporting is relatively independent of the clients actual psychopathology. Itwould be inappropriate to assume that evidence of underreporting or overreportingcan be used to conclude that the client does or does not have actualpsychopathology.A client may overreport andmanifest actualand severe symptomatology or may sub-stantially underreport and also be relatively free from actualsymptomatology. Finally,Greene observes that the MMPI-2 (and MMPI-A) scales used to assess consistency ofitem endorsement (VRIN and TRIN) are not appropriate or useful for evaluating theaccuracy of item endorsement.Greene cited several indices that may be used in determining response accuracywith the MMPI-2, including the Wiener-Harmon Subtle-Obvious subscales (Wiener,1948), the Lachar-Wrobel (1979) Critical Item List, and, most recently, the F(p) scaledevised by Arbisi and Ben-Porath (1995). Because of the empirical method of scaleconstruction used by Hathaway and McKinley in the development of the originalversion of the MMPI, the clinical scales contain numerous subtle items that seemunrelated to the construct that is the focus of measurement. Wiener and Harmon ra-tionally developed Subtle and Obvious subscales for five of the MMPI clinical scales:D, Hy, Pd, Pa,and Ma. Greene (2000) noted that when individuals overreport symp-tomatology, scores on the Obvious subscales would be expected to increase relative toSubtle scale values. Conversely, when individuals attempt to underreport symptoma-tology, Subtle subscale values will become elevated in relation to Obvious subscalevalues.Research on the Subtle-Obvious subscales in adult samples has been marked bycontroversial and mixed findings. Boone (1994,1995) observed that the internal reli-ability estimates for the Subtle subscales are unacceptably low and that the inclusionof the Subtle subscale items attenuates the reliability estimates for the basic clini-cal scales. Brems and Johnson (1991) explored the utility of the Subtle-Obvious sub-scales as profile validity indicators in a sample of 291 psychiatric inpatients. Theresearchers found these scales useful in identifying individuals who tend to overre-port symptomatology on the MMPIand other self-report measures. Dannenbaum andLanyon (1993) requested groups of college undergraduates to take the MMPI underone of three instructional sets involving standard administration, faking-good, and
  • 123. VALIDITY SCALES AND VALIDITY ASSESSMENT INTERPRETATION 109faking-bad. As expected, faking-bad subjects scored significantly lower than subjectsin the standard administration condition on the 100most subtle items, a result in-terpreted as consistent with the presence of multiple items whose content relevanceor face validity is opposite to the keyed direction of scoring on the Subtle subscales.These authors cautioned that although the subtle items have generally been shownto lack predictive ability, these items may prove useful in the detection of deception.Timbrook, Graham, Keiller, and Watts(1993)examined the MMPI-2profiles of49psy-chiatric patients and 105college students under various instructional sets to evaluatethe degree to which the Subtle-Obvious subscales correctly classified faked versusaccurate profiles. Although the authors found that the Subtle-Obvious subscales cor-rectly classified a relatively high proportion of profiles, they also reported that infor-mation from the Subtle-Obvious subscales provided no incremental gain above thatachieved through the use ofthe Land F scalesin accuratelyclassifying profiles. Bagby,Bins, and Nicholson (1995) compared the MMPI-2responses of participants asked tofake-bad with protocols from general psychiatric and forensic inpatient samples. Inaddition, these investigators examined the MMPI-2 responses of subjects asked tofake-good in comparison with the MMPI-2protocols of college students respondingaccurately to the instrument. These investigators also found that the F scalewas supe-rior to the Subtle-Obvious subscales in detecting fake-bad attempts but reported thatthe Subtle-Obvious index and the L scale were equally effective in detecting effortsto fake-good. Finally, Hollrah, Schlottmann, Scott, and Brunetti (1995) reviewed theliterature on the MMPI subtle items and concluded that the degree of support for thesubtle items varies depending on the type of methodology employed by the investi-gators and the specific Subtle subscale evaluated. These authors called for a clearerand more consistent research methodology to be employed by future studies inves-tigating this important issue. They also concluded that the strongest current supportfor the Subtle-Obvious subscale items lies in their apparent ability to detectfake-goodprofiles in psychiatric settings.Graham (2000) reached several conclusions criticalofthe use of the Subtle-Obvioussubscales with the MMPI-2. First, he suggested that the subtle items were originallyincluded in the MMPIbasic scales because the item analyses and the selection processdid not employ a cross-validation procedure. Second, he observed that obvious ratherthan subtle items are consistently related to extratestbehaviors. Third, he acknowl-edged that although individuals attempting to under- or overreport on the MMPIand MMPI-2 may correctly endorse subtle versus obvious items, the Subtle-Obvioussubscales do not permit accurate and consistent differentiation of valid profiles andunder- or overreported profiles. Fourth, Graham noted that the standard validityscales of the MMPI-2 appear to be as effective as or more effective than the Subtle-Obvious subscales in detecting deviant response sets. Graham concluded that theseand other problems with the Subtle-Obvious subscales led to the recent Universityof Minnesota Press decision to no longer include the Subtle-Obvious subscales inMMPI-2 test materials, interpretive reports, or scoring services.Very little is known about the usefulness of the Wiener-Harmon Subtle-Obvioussubscales in the assessment of adolescents. Herkov, Archer, and Gordon (1991) pro-vided the only study of the Wiener-Harmon subscales in an adolescent sample. Theseinvestigators compared the use ofthe standard validity scales inrelation tothe Wiener-Harmon subscales in terms of ability to accuratelyidentify adolescents in four groups:normal adolescents, psychiatric inpatients, normal adolescents instructed tofake-bad,and psychiatric inpatients instructed to fake-good. Table4.14 compares the classifica-tion accuracyachieved by using of the sum ofthe difference in T-scorevalues between

Obv. —Sub. = Obviousminus Subtle difference score; Pa-Obv. = Obvious subscale for the Paranoia basic scale;PPP = positive predictive power; NPP = negative predictive power.the Wiener-Harmon subscales (Obvious minus Subtle) and by using thetraditionalvalidity scales. Several points may be made in relation to these findings. First, theoptimal Obvious minus Subtle subscale difference values used in identifyingoverre-porting (>140)and underreporting (< 0)differ substantially from those recommendedby Greene (1989a)and others for adult respondents. Additionally, the Subtle-Obvioussubscales were of use in identifyingvarious response sets but were not as helpful assimple prediction rules applied to the standard validity scales. Specifically, identify-ing adolescents who produced F scale T-score values of 100 or above as overreportersand adolescents who produced L scaleT-scorevaluesof55or above as underreportersproved more accurate than predictions based on the Subtle-Obvious subscales.Be-cause of these findings, combined with the observations offered by Graham (2000)concerning limitations of the Subtle-Obvious subscales, the use of these subscales isnot recommended in clinical practice with the MMPI-A.The Lachar and Wrobel (1979) critical items consist of 111 empirically selectedMMPI items related to symptoms that may motivate individuals to seek psycho-logical treatment or related to symptomatology crucial in the cliniciansdiagnosticdecision making. Greene (1991,2000) recommended that the total number of Lachar-Wrobel critical items endorsed be used as an index of accuracyof itemendorsement.A patient who is attempting to overreport symptomatology, for example, might beexpected to endorse a large number of these items, whereas a patient underreportingpsychopathology would be expected to endorse relativelyfew critical items.Data on adolescent response patterns for the Lachar-Wrobel(1979)criticalitems onthe original MMPIwere provided by Greene (1991).This author reported thefrequen-cies of the critical item endorsement produced by adolescents and adults receivingservices in the Missouri public mental health system. These data, shown in Table4.15,indicate roughly comparable levels of criticalitem endorsement for these two groups.Archer and Jacobson (1993) examined the frequency of endorsement of the Koss-Butcher (1973) and the Lachar-Wrobel(1979) critical items in normative and clinicalsamples administered the MMPI-A or the MMPI-2.Adolescentsin both the normaland clinical samples endorsed clinical items with a higher frequencythan did normaladults.

Tables4.16 and4.17 provide the MMPI-2and MMPI-Amean item endorsement percentages for maleand female subjects for the Lachar-Wrobel critical categories as reported in Archerand Jacobson (1993). These findings underscore the difficulties inherent in creating acritical item list specificallyfor adolescents using the type of empirical methodologythat has been employed with adults (i.e., selection of items based on item endorse-ment frequency differences found between comparison groups). Beyond the technicaldifficulty of creatinga criticalitem list for the MMPI-A,several conceptual issues wereraised related to the application of critical items to the MMPI-A.Specifically, Archerand Jacobsonnoted that the concept of criticalitems has not been defined consistentlythroughout the history of the MMPI.Further, both the reliability and validity of criti-cal items may be inherently limited in adolescent populations. The authors concludedthat the commonly used MMPI/MMPI-2critical item lists that have been developedbased on adult samples may not be useful in the assessment of adolescents with theMMPI-A.Forbey and Ben-Porath (1998) recently developed a set of criticalitemsspecificallyfor the MMPI-A.Their research attempted to address the inadequacies inherent inprevious attempts to extend critical item lists generated for adults to use with ado-lescents. Item endorsement frequencies for boys and girls in the MMPI-A normativesample were examined, and any item that was endorsed in the scored direction bymore than 30%of the normal sample was removed from the pool of potential criticalitems. Items that were endorsed 30%of the time or less in the keyed direction werethen subjected to further analysis utilizing the response frequencies of adolescents ina clinical sample. Items differing in response frequency by more than 10percentage

For example, aninspection of the Depression/Suicidal Ideation content area may aid in determinat-ing whether a depressed adolescent has endorsed items suggestive of an increasedrisk for suicide.

This critical item list was not designed, however, and is not recommendedas a means of evaluating profile validity.Although it certainly warrants substantiallymore research and empirical evaluation, its development is well documented, andthe clinical uses recommended by Forbey and Ben-Porath appear both prudent andappropriate. Asnoted by Forbey and Ben-Porath,the alternative to using an MMPI-Acritical item set, from a practical standpoint, is for each clinician to select his or herown critical items and check the responses in the MMPI-A test booklet to ensurethese items are useful for interpretive or feedbackpurposes. Forbey and Ben-Porathobserved that searching through item responses to determine whether a client re-sponded in the keyed direction to particular items is both inefficient and ineffective.Clearly, the use of a standard list of criticalitems identified through a series of empiri-cal procedures such as those employed by Forbey and Ben-Porathis muchpreferableto individual clinicians reliance on nonstandard critical item selection.
  • 128. 114 CHAPTER 4SUMMARYThis chapter has provided an overview of the traditionalMMPIvalidity scales in theassessment of MMPI-A technical validity and has reviewed a number of MMPI-Aprofile features produced by various response sets. In addition, it has discussed sev-eral sets of validity-related measures developed for the MMPI-A, including TRINand VRIN scales and the FI and F2 subscales. Finally, it has presented the validityassessment model developed by Greene (1989a, 2000). This model encompasses asequential approach to MMPI and MMPI-A validity assessment and takes into ac-count the distinction between item endorsement consistency and accuracy. Withinthe Greene model, item endorsement consistency may be viewed as a necessary butnot sufficient component of valid response patterns.Adolescents are most likely to overreport psychopathology as a conscious or un-conscious plea for help in order to communicate their desire for attention and support.Conversely, adolescents are most likely to underreport symptomatology when theyhave been involuntarily placed in treatment by their parents or court officials andwish to underscore their perception that they do not have any significant problems.Additionally, adolescents will often underreport or overreport on the MMPI-A as aresult of inappropriate test instructions or testing procedures that influence them,either consciously or unconsciously, to distort their responses.Overall, there are currently insufficient data to support the use of the Wiener-Harmon Subtle-Obvious subscales. The MMPI-A Advisory Committee did not rec-ommend the creation of MMPI-A Subtle-Obvious subscale profile sheets becauseofthe lack of empirical evidence supporting the use of these measures in adolescentpopulations. The use of the traditional validity scales, individually and configurally,is recommended for the evaluation of response accuracy on the MMPI-A.As previ-ously noted, elevations of L and K, singly or in combination, in relation to the F scaleand subscales are related to conscious and unconscious efforts to underreport symp-tomatology. Further, the most open validity configuration (elevated F, low L and K)is related to conscious or unconscious efforts to overreport symptomatology on theMMPI-A.
  • 129. 5Basic Clinical Scale and Codetype Correlatesfor AdolescentsPROFILE ELEVATION ISSUES AND THE MMPI-APROFILE "SHADED" ZONEAs noted in previous chapters, adolescent MMPI-Aresponses should be interpretedexclusively through the use of age-appropriate adolescent norms. The conclusionthat adolescent norm conversion is the most appropriate means of interpreting ado-lescent responses does not imply that such a procedure renders the evaluation ofMMPI-A profiles either simple or straightforward. The most important difficultiesthat occur when interpreting adolescent responses scored on adolescent norms is thatthe resulting profiles typically produce subclinical elevations, even for adolescentsin inpatient psychiatric settings if a T-score value of 65 or above is employed as thecriterion for determining clinical-range elevation. The inherent contradiction in inter-preting a normal-range profile for an adolescent who exhibited evidence of seriouspsychopathology probably contributed to the inappropriate but widespread practiceof using adult norms for adolescents on the original version of the MMPI.Thus, justas the application ofadult norms to adolescent patterns tends to produce profilesthatgrossly overemphasize or exaggeratepsychiatric symptomatology,so the applicationof adolescent norms, either on the original version of the MMPIor the MMPI-A,pro-duces profilesthat often appear to underestimate an adolescents psychopathology.Normal-range mean profiles (e.g., mean T-scorevalues < 70)for inpatient adoles-cent populations on the original version of the MMPI have been reported by Archer(1987b), Archer, Ball, and Hunter (1985), Archer, Stolberg, Gordon, and Goldman(1986), Ehrenworth and Archer (1985), and Klinge and Strauss (1976). The result ofthis phenomenon for adolescent MMPI profile interpretation on the original MMPIinstrument was that the application of a T-scorecriterion of 70or above, traditionallyfound useful in defining clinical symptomatology for adult respondents, had sub-stantially less utility with adolescents. Based on these observations, Ehrenworth andArcher (1985)recommended the use of a T-scorevalue of 65for definingclinical-rangeelevations for adolescents on the original instrument. Employment of this criterionin inpatient and outpatient adolescent samples served to substantially reduce thefrequency of normal-range profiles obtained for adolescents (Archer, 1987b). For ex-ample, Archer, Pancoast, and Klinefelter (1989) found that the use of clinical scaleT-score values of 65 or above (rather than 70 or above) to detect the presence of115

Reprinted by permission.psychopathology resulted in increased sensitivity in accurately identifying profilesproduced by normal adolescents versus adolescents from outpatient and inpatientsamples. Archer (1987b) speculated that the "within normal limits" T-scoreelevationstypically found for adolescents on the original instrument were partially related to theabsence of ]<C-correction procedures as well as the high base rate of endorsement ofclinical symptoms typically found in samples of normal adolescents. Alperin,Archer,and Coates (1996) more recently showed, however, that an MMPI-A X-correctionprocedure was not effective in significantly reducing the number of false negativesproduced by this instrument.Figure 5.1 presents the profile of normal adolescents, scored on the Marks andBriggs (1972) traditional adolescent norms, from eight studies conducted between1947 and 1965 and compares it with the mean profile produced by normal adoles-cents in four studies conducted between 1975 and 1987 (Pancoast & Archer, 1988).These profiles (which present the validity scales in the traditional order) suggest thatdetectable changes have occurred in adolescentMMPIresponse patterns over the past40years, thus lending support tothe view thatacontemporary adolescentMMPInormset needs to be created.Figures 5.2 and 5.3 compare the post-1975 mean profile from the Pancoast andArcher (1988) review with the MMPI-A normative response patterns, separately bygender, as profiled on the Marks and Briggs (1972) adolescent norms using the con-version table in Appendix D. These data show that mean values from the MMPI-Anormative sample are relatively consistent with other samples of normal adolescentsthat have been collected since 1975. Because the MMPI-A normative set is based onadolescent response patterns that have higher mean scale raw score values than dothe original Marks and Briggsadolescent norms, a major effect of the MMPI-A normsis to reduce profile elevation for a given set of raw score values in comparison with

This is illustrated in Figs. 5.4 and 5.5, whichprovide a comparison of the MMPI profile elevations produced for a group offemale(n = 1,032) and male (n = 730) adolescent psychiatric patients as profiled on the tra-ditional Marks and Briggs (1972) norms and on the MMPI-Aadolescent norms (usingthe conversion tables in Appendix D). A comparison of profile elevations in thesefigures clearly demonstrates a reduction in MMPI scale T-score elevations related tothe use of the more recent adolescent norm set.In response to the profile elevation issues related to the use of the MMPI withadolescents and the further reduction in profile elevations produced by theMMPI-Aadolescent norms, an innovative strategy for determining clinical-range elevationswas developed for the MMPI-A. Specifically, rather than a "black line" value, thatis, a single T-score value that denotes the beginning of clinical-range elevations, arange of values was created that serves as a transitional zone between normal-rangeand clinical-range elevations. The use of this zone concept explicitly recognizes thatT-score values between 60 and 65 constitute a marginal range of elevations in whichthe adolescent may be expected to show some but not necessarily all ofthe clinical cor-relate patterns or traits associated with higher range elevations for a specificMMPI-Ascale. Conceptually, the use of a "shaded" zone recognizes that the demarcationpointor dividing line between normalcy and psychopathology during adolescence maybe less clear than during adulthood. Adolescents who are not deviant in a statisti-cal sense (i.e., who do not produce clinical-range elevations in excess of a particularT-score value) may still display behaviors or report experiences disturbing enough tobe labeled as clinicallysignificantand to require psychological intervention. As notedby Archer (1987b), the "typical" adolescent may experience sufficient psychological

Thus, in addition to the traditional categories of within-normal-limits andclinical-range elevations that have been typically associated with MMPIresponses, theMMPI-A has included a new category consisting of marginally elevated T-score values.Recent Studies on MMPI-A Profile Elevation IssuesNewsom et al. (2003) sought to explore changes in adolescent self-presentationon theMMPI and MMPI-A over a 40-year period. The primary data used for comparisonincluded data collected in 1989from 1,235 adolescents aged 12to 16 inclusive who werepart of the MMPI-A normative sample and data collected in 1948-1954 from 10,514adolescents in the same age grouping as part of Hathaway and Monachesis (1963)study of adolescent personality and behavior. Results showed a pattern of moderateto large changes in response frequencies between the eras of data collection, witha substantially higher rate of endorsement of items in the pathological direction byadolescents in the contemporary MMPI-A normative sample. This study providedevidence of changes in mean raw score values for many of the MMPI basic scales andHarris-Lingoes subscales and reported significantly higher rates of item endorsementfor contemporary adolescents on the 393items shared in common by the MMPI andMMPI-A. Overall, the results showed that contemporary normal adolescents not onlyendorse more psychopathological symptoms than do adults but also endorse morepathology than did adolescents 40years previously.

BASIC CLINICAL SCALE AND CODETYPE CORRELATES FOR ADOLESCENTS 121Researchby Archer,Handel, and Lynch(2001)compared the item endorsement fre-quencies for the MMPI-Anormative sample with results from two adolescent clinicalsamples, and these results were also compared with the item endorsement frequenciesreported for the MMPI-2 normative sample and a clinicalsample of adult psychiatricinpatients. Figure 5.6 shows the mean MMPI-Abasic scale profiles for 271boys and160 girls in inpatient settings reported in the MMPI-Amanual. Results of this studydemonstrated that the MMPI-A contained a substantial number of items that do notshow a significant difference in item endorsement frequency between normal andclinical samples. Furthermore, MMPI-Abasic and content scales generally showed amuch lower percentage ofeffective items than do corresponding scales oftheMMPI-2.Archer et al. (2001) discussed these results as a possible factor in the relatively lowrange MMPI-A profiles found for clinical samples.Following up on the research by Archer and his colleagues (2001), Lynch, Archer,and Handel (2004) examined the itemendorsement frequencies found fortheMMPI-Asupplementary scales, Harris-Lingoes scales, and Subtle-Obvious items in criteriongroups of adolescents in clinical settings grouped by gross diagnostic category. Ad-ditionally, these authors revised the basic scales by eliminating ineffective items, de-fined as items that failed to show a significant item endorsement frequency differencebetween normative and clinical populations. The results demonstrated that item ef-fectiveness did not appear to be significantly related to the homogeneity of diagnosticgrouping, nor to factors such as the obviousness or subtletyofitem content. These find-ings are shown in Table5.1for items classified as effective based on the discriminationperformance between the normative sample and two adolescent clinicalsamples (thesample reported in the MMPI-Amanual and an independent clinical sample) as wellas for items classified as ineffective in similar comparisons for the MMPI-2. Further,these results demonstrated that the overall effectiveness of the MMPI-Abasic scalescould be increased, in terms of sensitivity, specificity,positive and negative predictiveTABLE 5.1MMPI-A Basic Scale Items Classified Based on Discrimination Performance Between the NormativeSample and Two Adolescent Clinical Samples, With Similar Item Comparisons for the MMPI-2Normative Sample and an AdultClinicalSampleMMPI-A Percent Effective Items MMPI-A Percent Effective ItemsNormative/Clinical Samples Normative/Independent Samples MMPI-2 Percent Effective ItemsBoys Girls Boys Girls Men WomenH s ( l )D(2)Hy(3)Pd(4)Mf(5)Pa (6)Pt(7)Sc(8)Ma (9)Si (0)3% (1/32)28% (16/57)25% (15/60)63% (31/49)16% (7/44)30% (12/40)23% (11/48)18% (14/77)35% (16/46)11% (7/62)13% (4/32)40% (23/57)28% (17/60)71% (35/49)25% (11/44)33% (13/40)29% (14/48)30% (23/77)17% (8/46)19% (12/62)28% (9/32)40% (23/57)28% (17/60)69% (34/49)14% (6/44)48% (19/40)35% (17/48)45% (35/77)48% (22/46)24% (15/62)50% (16/32)54% (31/57)38%(23/60)67% (33/49)16% (7/44)23% (16/40)40% (19/48)44% (34/77)29% (14/46)19% (12/62)84% (27/32)70% (40/57)60% (36/60)72% (36/50)45% (25/56)73% (29/40)94% (45/48)92% (72/78)57% (26/46)70% (48/69)91%(29/32)66% (38/57)55% (33/60)72% (36/50)14% (8/56)70% (28/40)94% (45/48)97% (76/78)65% (30/46)64% (44/69)Note.

In general, the results of these recent studies clearlyshow that adolescents in the MMPI-Anormative sample endorsed psychopathologi-cal symptoms at a relatively high frequency and that this overall endorsement patternfor the normative sample may be a significant factor in the tendency of adolescentsin clinical samples to produce within-normal-limits profiles.Hilts and Moore (2003)examined the frequency base rates ofnormal rangeMMPI-Aprofiles in an inpatient sample of388adolescents. Further, these researchers examinedthe differences between adolescents with normal-range profiles (defined as profileswith clinical scale T-scores all below 60) and adolescents with elevated profiles interms of psychotherapy history, reported internalizing and externalizing symptoms,and MMPI-Avalidity scale scores. Hilts and Moore reported that 30%of maleand25%of female adolescents produced MMPI-A profiles in which none of the clinicalscaleswere elevated and that normal-range profiles could not be adequately explained bya less pathological history prior to hospitalization. Both male and female adolescentswith normal-range profileswere generally less likelyto report internalizing symptomsthan adolescents with elevated profiles, but both groups reported comparable levelsof externalizing symptoms. Hilts and Moore (2003) concluded:Thepresent study has implications forboth clinicians and researchers. Clinicians encoun-tering MMPI-A profiles with no significant elevations should consider the hypothesesthat the adolescents may not be experiencing feelings of distress or may not see them-selves as having problems; a profile with no elevations may not mean that the adolescentis not having problemsin some area of his or her life. Future research should addressthe issueof lack of apparent or acknowledged internal distress in some adolescents whopresent with externalizing symptoms, (p. 271)Two studies have examined the usefulness of reducing the standard T-score cutoffemployed to define clinical-range elevation on the MMPI-A from the standard T > 65to the T > 60criterion used by Hilts and Moore. Janus, Toepfer,Calestero, and Tolbert(1996) used a sample of 300adolescents in a psychiatric inpatient setting and reportedthat no significant gender differences in frequency of elevations on the MMPI-A wheneither the traditional or modified cutoff scores were used. These authors did report,however, that using T-scores < 60on all basic scales as the within-normal-limits crite-rion produced a substantial reduction in the number of false negative classificationsfor this clinical population in comparison with the traditionalT < 64 criterion.In theabsence of a sample of normal adolescents, however, Janus, Toepfer, et al. were notable to evaluate the overall impact of reducing the T-score standard used to defineclinical-range elevations on the occurrenceof false positives (i.e., the misclassificationof adolescents functioning normally produced by elevations on the MMPI-A basicscales). Fontaine, Archer, Elkins, and Johansen (2001) were able to address this lat-ter issue by comparing MMPI-A profiles from a sample of 203 adolescent inpatientswith subsamples from the MMPI-A normative group. Fontaine and her colleaguescompared the T-score elevation criteria T > 60 and T > 65 in definingclinical-rangeelevations when the clinical base rate for actual psychopathology was 20%and whenit was 50%.Classification accuracy analyses indicated that T > 65 resulted in higherlevels of accurate identification while minimizing misclassifications of both clinicaland normal cases. The results clearly suggest that using the T > 60criterion to reducethe frequency of false-negative misclassifications of adolescents in clinical samples isproblematic and may result in an unacceptably high rate of false-positive misclassifi-cations for normal adolescents.
  • 137. BASIC CLINICAL SCALE AND CODETYPE CORRELATES FOR ADOLESCENTS 123In summary, the current literature indicates that the MMPI-A tends to producerelatively low scores for adolescents in clinical settings. The evidence also suggeststhat this issue is not effectively resolved by developing a K-correction procedure forthe MMPI-A or by reducing the T-score elevation criterion from 65 to 60 in defin-ing clinical-range elevations. Recent findings appear to indicate that the relativelyhigh rate of endorsement of items in the pathological direction by adolescents in theMMPI-A normative sample may be one of the primary causes for the frequent within-normal-limit profiles found for adolescents in clinical settings. In this regard, Lynchet al. (2004) have noted that adolescents in the MMPI-Anormative sample were notexcluded based on history of psychotherapy. Approximately 200 of the adolescentsin the normative sample responded yes to an item on a life events form asking if theyhad "been referred to a therapist or a counselor" within 6 months of the administra-tion of the MMPI-A. This referral frequency is generally consistent with the 10% to15% estimates of the national incidence of adolescent psychopathology (as reportedin chapter 1),and subsequent analyses by Lynch et al. found that basic scaleT-scoreswere significantly higher for this referral group than for their counterparts in theMMPI-A normativesample who did not report being referred for therapy or counsel-ing. While the current evidence suggests that refinement of the MMPI-A normativesample to exclude adolescents receiving psychotherapy services or "improvement"of the MMPI-A item pool by deleting ineffective items may serve to reduce the dis-turbingly high frequency of within-normal-range profiles for adolescents in clinicalsettings, more research on this complex issue is clearly indicated.UNIFORM T-SCORE TRANSFORMATION PROCEDURESFOR THE MMPI-AAspreviously stated, the traditional adolescent norms developed byMarks and Briggs(1972), as well as the original MMPI norms for adults, used linear T-scoretransfor-mations to convertraw scorevalues to T-scores. Colligan, Osborne, and Offord (1980,1984) and Tellegen and Ben-Porath(1992), in their presentation of uniformT-scores,noted that linear T-score values have presented problems in the interpretation ofMMPI profiles because a given linear T-score value typically converts to differingpercentile equivalents across the various MMPI scales. Thus, a given T-score valueon the original Marks and Briggs (1972) norms may convert to percentile equivalentvalues that range as much as 10 to 15 percentile points across the 10 MMPI basicscales. This occursbecause the raw score distribution for different MMPIscales variesin shape (e.g., in skewness), whereas a linear T-score transformationprocedure willproduce equivalent percentile values for a given T-score only if the raw score distri-butions for the basic scales were each normally distributed. Because the basic scalesdisplay varying degrees ofskewness, the same linear T-score value will have differentpercentile equivalency scores across the different scales. Uniform T-scores representcomposite or averaged linear T-scores and serve to promote percentile equivalenceacross MMPI-Aclinicalscales (excluding5and 0)and contentscales. Uniform T-scoresdo not, however, have major effects on the underlying distribution of raw scores anddo not serve to "normalize" the underlying raw score distributions. This is importantin that the "true" distribution of scores on the MMPIscales may in fact notbe normal,and therefore a normalizing procedure may actually serve to distort T-scorevalues byartificially lowering those in the higher range (Tellegen &Ben-Porath, 1992).Table5.2shows the percentile values of uniform T-scores as derived for the basic scales on the

Reprinted by permission.MMPI-A and for the MMPI-2as reported by Ben-Porath(1990). As shown in this table,uniform T-scores do not correct or normalize the underlying raw score distributionsin such a way that a T-score value of 50 equals a percentile value of 50. Rather, theuniform T-score procedure makes relatively small adjustments in individual scale rawscore distributions achieved by creating a composite or overall distribution across theaffected scales. These adjustments permit comparable percentile equivalents to be as-signed to T-score values so that a given T-score will yield equivalent percentile ranksacross the eight clinicalscales and the content scales. Edwardset al. (1993b) comparedthe effects of MMPI-2 linear versus uniform T-score transformationsfor a sample of200 psychiatric outpatients. These authors reported that the differences created bythe uniform technique were relatively slight and that observed differences betweenMMPI and MMPI-2T-scores were mainly attributableto differences in response pat-terns in the normative sample rather than the use of uniform T-score transformationprocedures. Appendix C of this text contains uniform T-score transformationsforthe MMPI-A basic scales (with linear T-scores for the validity scales and basic scales5 and 0) and the content scales. Appendix C also contains linear T-score transfor-mations for the MMPI-A supplementary scales and for the Harris-Lingoes and Sisubscales.CODETYPE CONGRUENCE ISSUESA major area of controversy concerning the development of the MMPI-2centered onthe degree to which adult profiles produced by the revised instrumentwere compara-ble to or congruent with adult profilesproduced by the original MMPI(Archer, 1992c).For example, a series of articles by Dahlstrom (1992) and Humphrey and Dahlstrom(1995) suggested that the MMPI and MMPI-2 often produce substantially differentprofiles, whereas Tellegen and Ben-Porath (1993) and Ben-Porath and Tellegen (1995)responded with perspectives that stressed the comparability of profiles produced bythese two instruments. This issue has received substantialattention because it relates
  • 139. BASIC CLINICAL SCALE AND CODETYPE CORRELATES FOR ADOLESCENTS 125to the degree to which the research literature available on the interpretation of thetraditional MMPImay be generalized to theMMPI-2.Empirical research has slowly been accumulating on the congruence between theMMPI and MMPI-2. The MMPI-2manual (Butcheret al.f 1989) provides congruencedata for 2-point codes using MMPI-2 norms and the original test instrument normsin a sample of 232 male and 191 female psychiatric patients. These data indicate acongruence rate of approximately 70% for males and 65% for females when highpoints were defined as the most elevated clinical scaleregardless of the magnitudeofthe elevation. Graham, Timbrook, Ben-Porath, and Butcher (1991) reexamined thesedata and reported that when 2-point codetype elevations were "well defined"—thatis, there was at least a 5-point T-score difference between the second and third mostelevated scales in the clinical scale codetype—thecongruence rate increased to81.6%for males and 94.3%for females. Edwards, Morrison, and Weissman (1993a), Hus-band and Iguchi (1995), and Morrison, Edwards, Weissman, Allen, and DeLaCruz(1995) reported congruence rates ranging from 60% to 94% for well-defined code-types derived in clinical samples, with findings varying as a function ofthe definitionof congruence employed in these studies. In general, it is possible to conclude thatalthough the MMPI and MMPI-2 are not psychometrically equivalent, the two in-struments are likely to produce similar profiles, particularly when a 2-point codetyperepresents a well-defined configural pattern. For example, Clavelle (1992) asked ex-perienced MMPI users to review pairs of MMPI and MMPI-2profiles derived fromthe same test responses and to determine if these data yielded comparable clinicalresults. The 35 clinical psychologists in this study estimated that 92%to 96%of theirdiagnoses and 89%to 93%of their narrative interpretations would be essentially thesame or only slightly different between the two instruments. Harrell, Honaker, andParnell (1992) administered the MMPI, the MMPI-2, or both in a counterbalancedrepeated-measures study with adult psychiatric patients. Although MMPI-2T-scoreswere generally lower than MMPI T-scores on several of the clinical scales, the rankordering of T-scores and the dispersion of basic scale scores were essentially equiva-lent.Table 5.3provides data from the MMPI-Amanual (Butcher et al., 1992)on the con-gruence rate between profiles generated by normal adolescents based on the Marksand Briggs (1972)original norms and on the MMPI-Aadolescent norm set. It also pro-vides similar data comparing MMPI and MMPI-A profile characteristics for a groupof adolescents in psychiatric treatment settings. As shown, the overall congruencerate for profiles generated from the original test instrument and from the MMPI-Ais67.8% for boys and 55.8%for girls, with the congruence rate increasing to 95.2%forboys and 81.8% for girls when the criterion for 2-point codetype definition requires atleast a 5-point T-score difference between the second and third most elevated scale.In the clinical sample of adolescents, the overall congruence rate is 69.5% for boysand 67.2%for girls, and it reaches 95%for boys and 91%for girls when well-definedcodetype classification procedures are employed. Table 5.3 also shows the very dra-matic reductions that occur in the number of profiles classified into 2-point codetypeswhen the 5-point level of definition is required. These estimates for MMPIand MMPI-A congruence for adolescent samples are comparable to the congruence agreementrates reported for adults on the MMPI and MMPI-2 (Butcher et al., 1989; Graham,Timbrook, et al., 1991). Thus, it seems reasonable to assume that much of the MMPIclinical research literature for adolescent samples is generalizable to the MMPI-A,but it is erroneous to assume that all adolescent patients will produce equivalent orcongruent profiles across the two test instruments.

T-score difference between the second and third most elevated clin-ical scales in the MMPI codetype (using the Marks et al. norms).In the only study to explore the important issue of the relative accuracy ofadolescents MMPI versus MMPI-A profiles, Janus, Tolbert, Calestro, and Toepfer(1996) requested that clinicians blindly rate the accuracy of interpretive statementsbased on MMPI-A responses scored on (1)MMPI-Anorms, (2)the Marks and Briggsadolescent norms for the original MMPI,and (3)adult K-correctednorms for the orig-inal MMPI. Both sets of adolescent norms (original and MMPI-A)produced higheraccuracy ratings than did the adult norms, but the adolescent norms did not produceratings that differed between them. Janus, Tolbert, et al. (1996) concluded thatMMPI-A profiles based on standard MMPI-Anorms produced clinicalutility (accuracy) thatwas equivalent to profiles based on the Marks and Briggs adolescent norms for theoriginal instrument.

  • 143. BASIC CLINICALSCALE AND CODETYPE CORRELATES FOR ADOLESCENTS 129reported for the MMPI-2basic scales. Stein, McClinton, and Graham (1998) evaluatedthe long-term (one-year) test-retest reliability of MMPI-A scales and reported basicclinical scalevalues ranging from r = .51 for Pator = .75 for Si.Test-retest correlationsfor the content scales, in contrast, ranged from r = .40 for A-trt tor = .73 for A-sch.The typical standard error of measurement for the MMPI-Abasic scales is estimatedto be 2 to 3 raw score points (Butcher et al., 1992), which generally converts to 5T-score points. Thus, it is possible to state, as noted by Archer and Krishnamurthy(2002), that if an adolescent is readministered the MMPI-A within a relatively shorttime interval and without significant change in psychological functioning, his or herbasic scale T-scores would fall in a range of roughly ±5 T-score points of the originalscores approximately 50% of the time. The standard error of measurement is veryimportant when attempting to evaluate changes shown on the MMPI-A in terms ofseparating significantclinical changes from changes attributable to the standard errorof measurement. In general, changes in T-score values of 5 T-score points or less aremore likely to reflect measurement error rather than reliable change.The internal consistency of the MMPI-Abasic scales, as represented in coefficientalpha values, ranges from relatively low values on such scales as M/and Pa(r = .60)to substantiallyhighervalues for otherbasicscalessuch asHs(r = .78)andSc(r = .89).In contrast,internal consistency scores tend tobe higher for other MMPI-Ascales, suchas content scales, because alpha coefficient estimates were utilized in the constructionof these more recentMMPI-Ascales.In addition to test-retestand internalconsistencymeasures of reliability, the MMPI-Amanual (Butcheret al., 1992) also provides infor-mation concerning the item endorsement frequencies and reading levels required byeach of the MMPI-A items and the principal components analysis (PCA) structureof the MMPI-Abasic scalesusing a varimaxrotation procedure. Butcheret al. (1992)reported that a PCA of the MMPI-A basic scales resulted in a four-factor solution,appropriate for both boys and girls, with a large first factor labeled General Malad-justment. The second factor was labeled Over Control and is marked by high loadingson L and K, and the third and fourth factors appear tobe best described as nonclinicaldimensions related to Si and Mf, respectively.THE CODETYPE INTERPRETATION APPROACHAs noted by Graham (2000), configuralapproaches to the interpretation of the MMPIhave been viewed as potentially the richest source ofdiagnostic and descriptive infor-mation derivable from this test instrument. The early writings on the MMPI (Meehl,1951,1956; Meehl & Dahlstrom, 1960)emphasized the interpretation of codetype in-formation, and several ofthe early MMPIvalidity studies were focused on identifyingreliable clinical correlates of MMPI2-point codetypes (e.g., Meehl, 1951).A 2-point codetype is usually referred to by the numerical designation of the twobasic clinical scales that are most elevated in that profile, with convention dictatingthat the most elevated scale be designated first in the codetype sequence. Thus, ifan adolescent produces his or her highest T-score elevations on scales Pd and Ma (inthat order), the profile would be classified as a 4-9 codetype. Throughout this text,individual MMPI-A scales have often been referred to by their names or alphabeticabbreviations rather than numerical designations. This procedure has been followedto minimize confusion for the novice MMPI-A user. In discussing codetype classifi-cations, however, MMPI-A scales are referred to in this chapter by their numerical
  • 144. 130 CHAPTER 5designation, as in the codetype literature. In addition to MMPI tradition, numericaldesignation of scales is the generally preferred practice among experienced MMPI-2and MMPI-Ausers for a very important reason: The names that were originallygivento clinical scales may be misleading and may serve as inadequate labels of what thatscale is currently believed to measure. Forexample, the Psychasthenia scale was orig-inally developed to measure symptomatology related to what was later referred toas obsessive-compulsive neurosis and now is termed obsessive-compulsive disorder.Psychasthenia is not a psychiatric label in common use today, and Graham (2000)noted that the Pt scale is currently thought of as a reliable index of psychologicaldistress, turmoil, and discomfort, particularly as these relate to symptoms ofanxiety,tension, and apprehension.Several codetype "cookbook" systems have been developed, such as those pro-vided by Gilberstadt and Duker (1965) and Marks and Seeman (1963), and thesehave employed very complex rules for classifying multiscale elevations. However,the more recent efforts regarding codetype descriptors have tended to employ muchsimpler 2-point approaches to classifying MMPI profiles.Thesesystems, such as thoseexemplified in Friedman et al., (2001), Graham (2000), and Greene (2000), have typ-ically interpreted codetypes based on the two scales with the highest clinical-rangeelevations. Several investigations, such as that by Lewandowski and Graham (1972),demonstrated that reliable clinical correlates can be established for profiles that areclassified based on the simpler 2-point code systems. Data reported by Pancoast et al.(1988) also indicate that assignments to simple codetype systems canbemade with ac-ceptable levels ofreliability by independent raters. Additionally, diagnoses derived bythe simpler MMPI classification systems provide levels of agreement with cliniciansdiagnoses comparable to those achieved with more complex methods of MMPI pro-file classification. The obvious advantage of using the 2-point code system is thata much larger percentage of profiles can be classified in a typical clinical settingwhen numerous stringent criteria are not required for codetype assignment(Graham,2000).Of primary importance in employing codetype descriptors with any populationis a clear understanding that the attribution of correlate descriptors to a particularclient entails probability estimates. These estimates of accuracy may vary greatlybased on the source of the descriptor statement (adequacy of research methodol-ogy, characteristics of the population sampled, statistical strength of findings) andthe individual characteristics of the client being assessed (the base rate for similarsymptoms/diagnoses in the general psychiatric population). Additionally, it is likelythat the accuracy of descriptor statements will vary based on the degree of elevationand definition exhibited by a codetype (i.e., the degree to which the 2-point code isclinically elevated and whether it is elevated substantially above the remainder of theclinical scale profile). Even under optimal conditions, such as where cross-validatedresearch has led to the derivation of clinical correlates from MMPI profiles highlysimilar to that of the individual being evaluated, a specific clinical correlate may befound not to apply to a specific individual. Thus, as Greene (2000) noted, MMPIcook-books, even in adult populations, "have not been the panacea that was originallythought: Increasing the specificity of a particular codetype helps by enhancing thehomogeneity of the group and increasing the probability of finding reliableempiricalcorrelates; however, it also substantially reduces the number of profiles that couldbe classified within a codetype" (pp. 289-290). Nevertheless, codetypes continue toserve as a valuable source of hypotheses concerning client characteristics when suchcautions are borne in mind by the interpreter.
  • 145. BASIC CLINICAL SCALE AND CODETYPE CORRELATES FOR ADOLESCENTS 131DERIVING A CODETYPE CLASSIFICATION FOR ADOLESCENTSIn the adult codetype information provided by such sources as Graham (2000), Greene(2000), and Friedman et al. (2001),profiles are typically classified as 2-point codetypesbased on the two clinical scales that show the greatest degree of clinical-range eleva-tion. In these and most other systems, few high-point codetypes involve the scales5 and 0 because these scales have often been excluded from designation as clinicalscales. These scales were also frequently excluded in codetype research in earlyMMPIinvestigations (Graham, 2000).In general, 2-point codes are used interchangeably; for example, 2-7codetypes areseen as equivalent to 7-2codetypes, unless differences are specifically noted. Further-more, the absolute elevation of two high-point scaleswithin the profile is typically notconsidered beyond the assumption that such elevations occur within clinicalranges.The relative elevation of the two highest scales in relation to the remaining profileis also not typically considered or discussed in codetype narratives. As previouslynoted, however, the degree to which the 2-point codetype is well defined appears tobe related to the short-term stability of the codetype (i.e., the degree to which pro-file characteristics are subject to change over relativelybrief periods of time) and thedegree to which clinical correlate patterns will be applicable for a codetype config-uration. In standard codetype interpretation practice, if a profile does not fit any ofthe two-point codetypes presented, the clinician is generally advised to employ aninterpretation strategy based on clinical correlates found for the individual MMPIscales that are elevated.Marks et al. (1974) developed a classification system for adolescent MMPI profilesdesigned to increasethe clinicians flexibility in renderingcodetypeassignments.Oncean adolescents MMPI profile had been plotted, Marks et al. recommended that theresulting configurationbe compared to the codetype profiles they provided in termsof the two highest elevations occurring within that particular profile. If the codetypefor the individual adolescent corresponded to one of the 2-point codetypes presentedby Marks et al., the clinician was referred to the codetype descriptors appropriatefor that configuration. If the respondents codetype was not classifiable, however,the authors recommended dropping the second high-point scale and substituting thethird-highest scale to produce a new 2-point code. If this procedure then resulted ina classifiable codetype, the clinician was encouraged to interpret the profile basedon the clinical correlate information provided for that code. If the profile remainedunclassifiable following this "substitution and reclassification" procedure, Marksetal.suggested that their actuarial interpretation system notbe applied for that respondent.As commonly recommended in the interpretation of MMPI-2profiles, these authorsencouraged clinicians with unclassifiable profiles to employ a single-scale correlateinterpretive strategy.Alex Caldwell (asreported in Friedman et al., 2001)developed a system for classify-ing and interpreting profiles that, because of multiple-scale clinical-range elevations,do not fit cleanly into simple two-point codetypes. This system, which is referred toas the A-B-C-D Paradigm, divides the multiply elevated clinical-scaleprofile into dis-crete two-point codetype entitiesand builds the interpretivenarrativebased on clinicalcorrelate descriptors that are commonly found across these 2-point codes. Figure5.7provides an illustration of the Caldwell A-B-C-D Paradigm applied to an adolescentMMPI-A profile characterizedby elevations on scales4,8,2,and 6.This profile is usedto demonstrate Caldwells method of breaking down a multiply elevated profile intomore easily interpretable 2-point codes.

  • 147. BASIC CLINICALSCALEAND CODETYPE CORRELATES FOR ADOLESCENTS 133As shown in this figure, the four most elevated clinical scales (elevated withinclinical ranges)are assigned a corresponding letterofthe alphabet in order ofelevationmagnitude. The profile is then divided into high-point pairs using the combinationsA-B, A-C, A-D, B-C, B-D, and C-D. Descriptors commonly shared by these 2-pointcodetype classifications apply to an adolescent who might be described as impulsive,maladaptive, and antisocial and whose interpersonal relationships are characterizedby conflict. The interpretation would place more emphasis on codetype correlatesfor4-8 and 4-2given the relative prominence of these features within this MMPI-A profileand place less emphasis on codetypes such as 8-6 and 2-6 because of the relativelyweaker elevations for these latter configural features.When contradictory descriptorsare derived, emphasis will be placed on the primary codetype descriptors (e.g., A-B)rather than the secondary scale pairs (e.g.,C-D).As for recommendations for the clinician deriving codetype assignments, it ap-pears most appropriate to employ a simple codetype strategy that seeks to place anindividual profile into a codetype classification based on the highest 2-pointcharacter-istics occurring within clinicalranges for that profile. The clinicianshould be mindful,however, that less elevated and less well defined codetypes (the degree of elevationof the 2-point code relative to the remainder of the profile) are likely to manifestfewer of the correlate features associated with that particular codetype. When clas-sification does not result in an appropriate two-point codetype placement for whichclinical correlate information is available from standard sources, it is suggested thatthe clinician interpret the profile based on single-scale correlates. The substitutionand reclassification procedure suggested by Marks et al. (1974) is not recommended.For clinical profiles with more than two scales elevated within clinical ranges, theexperienced interpreter may wish to consider use of the Caldwell A-B-C-D Paradigmas an interpretivestrategy.SINGLE-SCALE AND TWO-POINT CODETYPESA substantial research literature has developed on the clinical correlate patterns ex-hibited by adolescents on the basic MMPI scales. Hathaway and Monachesi (1963),for example, investigated high-point and low-point correlate patterns for approxi-mately 15,000 ninth graders who were administered the MMPIin the Minnesota pub-lic school system in 1948 and 1954. Lacharand Wrobel (1990) and Wrobel and Lachar(1992) more recently examined single-scale correlate patterns in a sample of adoles-cents predominantly from outpatient settings, with analyses conducted separately bygender. Information concerning the correlates of basic MMPIscales for inpatient ado-lescents was examined in research studies by Archer et al. (1985),Archer and Gordon(1988), Archer et al. (1988),Ball et al. (1987), and Williams and Butcher (1989a).Single-scale correlates for the MMPI-Abasic clinicalscales were reported in the manual forthis instrument by Butcher et al. (1992). Additionally, information concerning corre-late patterns for various codetype configurations was presented by Archer (1987b),Archer and Klinefelter (1992), Archer and Krishnamurthy (2002), Marks et al.(1974),and Williamsand Butcher(1989b). These research investigations and summaries serveas the primary sources of single-scale and codetype correlate data presented in thischapter.In deriving the following codetype descriptors for adolescents, the 29 codetypesreported by Archer (1987b) were selected for presentation. In general, the core ofthis clinical correlate information is based on the Marks et al. (1974) data reported
  • 148. 134 CHAPTER 5for high-point codetypes occurring within clinical ranges. This information was thensupplemented with adult correlate information for these 29 high-point pairs fromFriedman et al. (2001), Graham (2000), Greene (2000), and Lachar (1974). The typicalnarrative created by this method begins with statements found to be common acrossboth the adolescent and adult descriptors for a particular MMPI configuration, basedon the observations by Archer (1987b) and Archer et al. (1988) that MMPI scale de-scriptors found in studies of adolescents have typically been consistent with thosefound in adult studies. Further, when sources of adult correlate data were not avail-able for a particular codetype, a relatively rare occurrence, this is noted in the firstfew sentences of the narrative. When marked or important differences occurbetweendescriptors derived from adolescent and adult clinical populations, the interpretiveimplications of these discrepancies are presented. Finally, codetype frequency datafor adolescents are based on our analyses of the codetype classification data for 1,762adolescent patients (Table 5.5), as scored on MMPI-A norms.In addition to the 29 codetype narratives, the following sections also contain in-formation on the characteristics of each of the 10MMPI-A basic clinical scales. Highand low single-scale correlates are suggested based on findings reported in studies ofadolescent samples in normal and/or psychiatric settings. In the case of single-scalehigh-point correlates, the descriptions are enriched by the MMPI-Acorrelateresearchreported in the test manual (Butcher et al., 1992). Much of the codetype correlate in-formation provided in the following sections is based on research conducted with theoriginal form of the MMPI utilizing the traditional adolescent norms as derived byMarks and Briggs (1972). This approach is similar to that taken by Butcher (1990),Friedman et al. (2001), Graham (2000), and Greene (2000) in the generation of code-type findings for the MMPI-2. The generalization of MMPI findings to the MMPI-Aappears supported in that the MMPI-Aclinical scales (except M/and SO have retainedbasically the same items as their counterparts in the original instrument. Further, aspreviously discussed in this chapter, the codetype congruence data for the MMPIandMMPI-A indicate that these instruments will produce similar or equivalent profilesin a majority of cases. Empiricalresearch findings are still needed, however, concern-ing the degree to which codetype correlates found for adolescents on the originaltest instrument may be validly generalized to the MMPI-A. Examinations of MMPI-2 codetype correlates for adult psychiatric patients have found a striking degree ofsimilarity in the descriptors identified for MMPI-2-based codetypes in inpatient set-tings (Archer et al., 1995) and outpatient settings (Graham et al., 1999) in relation tocorresponding codes derived from the original MMPI. The issue of generalizabilityof findings from the original MMPI will become less important, however, as researchprojects generate a new correlate literature based directly on studies conducted withthe MMPI-A.Scale 1 (Hs: Hypochondriasis) CodetypesScale 1 originally consisted of 33 items developed to identify respondents who man-ifested a history of symptomatology associated with hypochondriasis. These symp-toms include vague physical complaints and ailments and a preoccupation with bod-ily functioning, illness, and disease. One item was dropped from the original scale inthe creation of the MMPI-A due to objectionable content, resulting in a revised scalelength of 32 items. Graham (2000) reported that scale 1 appears to be the most unidi-mensional and homogeneous MMPI clinical basic scale in terms of item compositionand content. All of the items on scale 1 relate to somatic concerns and complaints.
  • 149. BASIC CLINICAL SCALE AND CODETYPE CORRELATES FOR ADOLESCENTS 135Research using adult samples has established that individuals who score high onscale 1typically report many somatic symptoms and exaggerated complaints regard-ing physical functioning. Additionally, Graham (2000) noted that adults who produceelevated scale 1 MMPI profiles are not psychologically minded and often use phys-ical complaints as a means of controlling or manipulating significant others in theirenvironment.Reports concerningphysical functioning on scale 1 would also be expected to beinfluenced by the individuals actual physical condition—respondents with phys-ical illness typically produce moderate subclinical elevations on this measure. Forexample, Ball et al. (1987) found subtle but detectable neurological differences be-tween adolescent psychiatricinpatients with and without marked scale 1elevations.MMPI profiles with scale 1 elevations have also been reported for adolescents withmedical problems, including epilepsy (Dodrill & Clemmons, 1984), muscular dys-trophy (Harper, 1983), nonprogressive physical impairments (Harper & Richman,1978), Gilles de la Tourettes syndrome (Grossman, Mostofsky, & Harrison, 1986),sleep disorders (Monroe &Marks, 1977), surreptitious insulin administration amonginsulin-dependent diabetics (Orr, Eccles, Lawlor, & Golden, 1986), and rheumaticfever (Stehbens, Ehmke, & Wilson, 1982). Colligan and Osborne (1977) investigatedthe MMPI response features of 659 female and 534 male adolescents (aged 15-19)who presented at the Mayo Clinic for medical evaluation, and they found that theseadolescents produced higher scores on the neurotic triad (scales 1,2, and 3). Profileswith elevations on scale 2 were unusual in the normal adolescent data collected byHathaway and Monachesi(1963), although a largernumber of these adolescentswereclassified as producing their lowest value on thisscale.High Scores on Scale 1The following is a summary of descriptors for high scale 1 scores (T > 60):• Excessive somatic and bodily concerns that are likely to be vague in nature.• Likelyto display somatic responses to stress, which mayinclude eating problems.• Increased likelihood of problems related to neurotic diagnoses.• Likely to be seen by others as self-centered, pessimistic, dissatisfied, and cynical.• Demanding, critical, selfish, and whining in interpersonal relationships.• Likely to display little insight in psychotherapy.• Less likely to engage in delinquent behaviors.• Likely to report schoolproblems, includingacademic and adjustment difficulties.Low Scores on Scale 1Low scale 1 scores have been associated with the following characteristics(T <40):• Few physical symptoms and freedom from somaticpreoccupation.• Higher scores on tests of intelligence.• More likely to come from urban than rural settings.• Greater psychological sophistication and insight.1-2/2-1 Codetype. Adolescent and adult clients with this codetype frequently com-plain of physical symptoms, including weakness, fatigue, and tiredness. These indi-viduals often show a consistent pattern of somatic preoccupation and overreaction
  • 150. 136 CHAPTER 5to minor physical dysfunction. Marked affective distress appears to be associatedwith the 1-2/2-1 codetype, and these individuals are often described as ruminative,tense, anxious, and insecure. There are also frequent reports of depression, socialwithdrawal, and isolation.Inboth the adult and adolescent literatures,the 1-2/2-1 codetype hasbeen associatedwith a very low probability ofacting out being used as a primary defense mechanism.There are often marked interpersonal concerns and unmet needs for attention andapproval by others. Thus, individuals who produce this codetype havebeen describedas fearful and hypersensitive in their interactions with others and often as dependentand indecisive.The 1-2/2-1 codetype occurred with a frequency of 0.9%for males and 2.2%forfemales in our sample of adolescent psychiatric patients scored on MMPI-Anorms.Marks et al. (1974) reported that obsession and compulsion are the primary mech-anisms of defense employed by adolescents with the 1-2/2-1 codetype. Adolescentswith this codetype in the Markset al. sample often complained ofbeing teased by oth-ers during their childhood and indicated that they were afraid of makingmistakes.They appeared to be quiet, depressed teenagers who established very few friend-ships and often manifested obsessional defenses. Although Graham (2000) reportedthat adults with the 1-2/2-1 profile often displayed excessive use of alcohol, the ado-lescents in the Marks et al. study with this codetype did not manifest significantdrug or alcohol involvement. Finally, Marks and his colleagues noted that adoles-cents with this codetype often had histories that included parental separation anddivorce, academicproblems (in several cases, school phobias), and delayedacademicprogress.1-3/3-1 Codetype. Sources of adult and adolescent clinical correlate data indicatethat individuals with the 1-3/3-1 codetype typically present themselves asphysicallyor organically ill. Indeed, when the T-scorevalues for scales 1and 3 are each above65and also each exceed the T-score value for scale2 by at least 10points, this profile maybe described as a classic conversion V. The types ofphysical complaints that have beennoted in the general literature for the 1-3/3-1 codetype include headaches, dizziness,chest pain, abdominal pain, insomnia, blurred vision, nausea, and anorexia.Itwouldbe expected that these physical symptoms would increase in times of psychologi-cal stress, and the clinician might be advised to attempt to identify secondary gaincharacteristics associated with this symptomatology.In the literature on adults and adolescents, the 1-3/3-1 codetype is associated morewith neurotic and psychophysiological symptomatology than with diagnosesrelatedto psychoses. These respondents are frequently perceived as insecure and attentionseeking.Behaving in socially acceptable ways appears important to the 1-3/3-1 person.The adult or adolescent 1-3/3-1 has problems establishingrelationships with membersof the opposite sex. Often, these problems are related to the lack of development ofappropriate skills in these interpersonal areas. Primary defense mechanisms for thiscodetype consist of somatization, denial, and externalization.As shown in Table5.5, 2.2% of male and 6.0%of female adolescents in psychiatricsettings produce the 1-3/3-1 codetype. Data unique to adolescent clinicalsources forthis profile indicate that 1-3/3-1 teenagers are more frequently referred for treatmentbecause ofproblems or concerns in their academic settings. Themajority of adolescentsin the Marks et al. (1974) sample indicated that they had a fear of receiving poorgrades, a concern that appeared realistic in view of the fact that 44% of this samplewere a year behind their age-appropriate academic placement. In general, Marks
  • 151. BASIC CLINICAL SCALE AND CODETYPECORRELATES FOR ADOLESCENTS 137et al. noted that adolescents with this codetype often displayed "diagnostic insight"into the descriptive features of their psychological problems. They were able to talksuperficially about conflicts and were not evasive in psychotherapy. These features arein contrast to the descriptors in the adult literature indicating that 1-3/3-1 individualstypically display little willingness to acknowledge psychological factors in their lifeproblems and little insight into their problems. Of the 20 patients in the Marks et al.1970-1973 sample who produced a 1-3/3-1 codetype, over two thirds had no historyof drug abuse or drug involvement.1-4/4-1 Codetype. The 1-4/4-1 codetype is relatively rare among adults, and it isfound in approximately 1.5% of male and 0.3%of female adolescents in psychiatricsettings. In the sources of adult and adolescent clinical correlate information, the1-4/4-1 individual appears to be defensive, negativistic, resentful, pessimistic, andcynical. Furthermore, research findings suggest these individuals may be describedas self-centered and immature. The use of somatic complaints is a primary defensemechanism for both adolescents and adults, although this feature is more prevalentamong adolescents with higher elevation on scale 1 than on scale4.In addition to these features, derived from the combined literature, a number ofcharacteristics appear to be uniquely related to the adolescents 1-4/4-1 codetypes.Specifically, more scale 4 features are reported as descriptive of adolescents with thiscodetype, including defiance, disobedience, and provocative behaviors. These prob-lemareas aremost likely manifestedin the relationship between the adolescent and hisor her parents. In the psychotherapy relationship, adolescents with this codetype havebeen described as superficial, cognitively disorganized, and moderately impaired injudgment. Therapists in the Marks et al. (1974) study rated most adolescents with a1-4/4-1 profile as manifesting a mild to moderate degree of psychiatric disturbanceoverall. In addition to the somatization, adolescents with this codetype often em-ploy acting out as their primary defense mechanism. Therapists describe adolescentpatients with this codetype as aggressive, outspoken, resentful, headstrong, and ego-centric. Despite the use of acting out as a primary defense mechanism, adolescentswith the 1-4/4-1 codetype in the Marks et al. sample were typically not found to besubstance abusers.1-5/5-1 Codetype. The 1-5/5-1 is a relatively infrequent codetype among adults andis found in less than 1% of male and female adolescents in psychiatric treatment. Inboth the adult and adolescent literatures, the 1-5/5-1 is often accompanied by somaticcomplaints ofa hypochondriacal nature, and patients with this codetype often presentas physically ill. Additionally, these individuals are often seen as passive, and theadolescent data indicate that teenagers with this codetype are unlikely to enter intoopen conflict or disagreement with their parents.Teenagers with this codetype are often referred for treatment by parents and byschool officials. Primary therapists view these adolescents as displaying mildly inap-propriate affect, and compulsion appeared to be a primary defense mechanism of thiscodetype. Interestingly, many ofthe 1-5/5-1 teenagers in the Marks et al. (1974) sampleactually had experienced serious physical illnesses as children. Therapists described1-5/5-1 adolescent patients as having difficulty in discussing their problems and con-flict areas, and these teenagers were seen as unreliable in terms of the informationthey provided to their therapists. They were not generally liked by others and haddifficulty in forming close relationships. Finally, teenage males with this codetypewere described as effeminate.
  • 152. 138 CHAPTER 51-6/6-1 Codetype. Of the adult sources reviewed, only Greene (1980, 2000) andFriedman et al. (2001) provide descriptive summaries for the 1-6/6-1 profile. Greenesbrief description of this codetype emphasizes the occurrence of hypochondriacalsymptomatology combined with hostile and suspicious traits related to elevationson scale 6. Additionally, he noted that the personality structure of the adult 1-6/6-1appeared resistant to change resulting from psychotherapy. In contrast, the investiga-tion of adolescent 1-6/6-1 codetypes by Marks et al. (1974) produced a quite differentpicture. Confidence in any codetype descriptors for this configuration must be tem-pered, however, by awareness that little research has been done in adult settings andthat the 1-6/6-1 codetype reported by Marks et al. was based on a very small samplesize (N = 11).Among adolescent psychiatric patients, only 1.2% of males and 0.4% offemales produced 1-6/6-1 codetypes (see Table5.5).Hypochondriacal tendencies and somatic complaints do not appear to be charac-teristics of adolescents with the 1-6/6-1 codetype. Rather, these adolescents were pri-marily referred for psychotherapy because of excessive emotional control.Therapistsviewed these teenagers as evasive, defensive, and fearful of emotional involvementwith others. More than half of these adolescents lived with their mothers in father-absent homes. When fathers were present in the family of these teenagers, their atti-tude toward the adolescents was reported to be rejecting. The 1 -6/6-1 adolescent wasviewed as egocentric and prone to rationalization as a defense mechanism. Data fromthe Marks et al. (1974) sample indicated some drug abuse for this codetype, but itwas not widespread or characteristic of this code. Intense anger directed at parentswas frequently displayed by this group, including occasional violent outbursts. Sui-cidal attempts, perhaps representing an internalization of rage and anger, were alsocharacteristic of the 1-6/6-1 adolescent in the 1970-1973 sample.1-8/8-1 Codetype. The adolescent and adult literaturesemphasize that those witha1-8/8-1 codetype exhibit correlates commonlyassociated with both scales 1and 8.Indi-viduals with this profile type frequently present somatic concerns such as headachesand insomnia and often perceive themselves as physicallyill.There are additionaldatafrom adolescent sources to suggest that teenagers with this codetype in fact often hadserioushealth problemsduring childhood. These adolescents also frequently reportedhistories of poor social adjustment and social inadequacy. Further, individualswiththe 1-8/8-1 profile appear to have difficulty in formingand maintaininginterpersonalrelationships. There is evidence in both the adolescent and adult literatures that the1-8/8-1 codetype is often associated with delusional or disordered thinking, includingsymptoms related to difficulty in concentration and thought processes. Adolescentswith the 1-8/8-1 codetype often described themselves as distractible and forgetful.Approximately 0.9% of male and 0.8%of female adolescents in psychiatricsettingsproduce the 1-8/8-1 codetype. Several clinical descriptors are uniquely available forthis codetype classification from the Marks et al. (1974) study. The 1-8/8-1 adolescentsfrequently reported problems during childhood involving being teased and harassedby peers and often had difficulty with academics, including reading. Overall, theiradjustment appeared tobeproblematic both in and outsideofschool settings,and theyexperienced substantial difficulty in making friends. Nearly one half of the 1-8/8-1teenagers in the Marks et al. sample were a grade behind their expected academicplacement.Unique among the groups with 2-point codetypes involving scale 2, the 1-8/8-1adolescents in the Marks et al. sample were likely to be involved in drug abuse,and over 50% reported a drug use history. Data from Archer and Klinefelter (1992)
  • 153. BASIC CLINICAL SCALE AND CODETYPE CORRELATESFOR ADOLESCENTS 139also indicate that adolescents with this codetype frequently exhibit elevated valueson the MacAndrew Alcoholism scale. Additionally, attempted suicides frequentlyoccurred among these adolescents; indeed, 65% had attempted to take their ownlives. Finally, intense family conflict was present for a very high percentage of the1-8/8-1 teenagers, often involving fighting or overt conflict with their parents. Twothirds of these adolescents were from families in which the parents were divorced.Scale 2 (D:Depression)CodetypesScale 2 originally consisted of 60 items, of which 57 were retained in the MMPI-Ascale 2. The essential characteristics of this MMPI-Adimension include poor morale,lack of hope for the future, and general dissatisfaction with ones life status andsituation (Hathaway & McKinley, 1942). The major content areas involved in thisscale include lack of interest in activities or general apathy, physical symptoms suchas sleep disturbances and gastrointestinal complaints, and excessive social sensitivityand social withdrawal. Graham (2000) described scale 2 as a sensitive measure of therespondentslife discomfortand dissatisfaction.Henoted that although very elevatedvalues on this scale are suggestive of clinical depression, more moderate scores havegenerally been seen as reflectiveof a life attitude or lifestyle characterized by apathyand poor morale. The content subscales derived by Harris and Lingoes (1955) forscale 2 include SubjectiveDepression (D1), Psychomotor Retardation (D2),PhysicalMalfunctioning (D3),Mental Dullness (D4), and Brooding(D5).Scale 2 high points were very infrequent among adolescents in the Hathaway andMonachesi (1963) Minnesota sample. Profiles whose lowest values were on scale 2,however, were relatively more common among these adolescents. Greene (2000) re-ported that adult psychiatric patients who produce elevations on scale 2 generallyhave characteristics of clinically depressed individuals, including feelings of inade-quacy, lack of self-confidence, guilt and pessimism, and self-depreciation. Greenealsonoted that individuals who produce spike 2 profiles tend to be good psychotherapycandidates and often show significant improvementas a result of relativelybrief psy-chiatric interventions. Consistent with this finding, Archer et al. (1988) found thathigh scale 2 inpatient adolescents were perceived by clinicians and psychiatric staffas more motivatedto engage in psychotherapy and openly discuss their feelings andperceptions. Theywere also less likely than other adolescents to engage in rebellious,deceitful, manipulative, or hostile behaviors. In addition, Archer and his colleaguesfound that high scale 2 adolescents were described as more introspective, self-critical,guilty, and ashamed and more likely to have problems involving suicidal thoughtsor ideation. Butcher et al. (1992), based on analyses of MMPI-A data, found thatadolescent inpatients with scale 2 elevations were more likely to be characterizedas depressed and more likely to have problems related to suicidal ideation and/orgestures. Archer and Gordon (1988), however, found no evidence of a significantrelationship between scale 2 elevations among adolescent inpatients and cliniciansuse of depression-related diagnoses, including dysthymia and major depression.Re-search by Nelson (1987) suggested that scale 2may more accurately identify clinicallydepressed individuals when only face-valid or obvious Depression scale items areemployed. Nelson and Cicchetti (1991) replicated and expanded these findings inan outpatient adult sample composed of individuals suffering from milder forms ofmaladjustment.Although clinical lore holds that scale 2 results may be predictive of suicide at-tempts, the empirical literature does not appear to support this assumption. Marks
  • 154. 140 CHAPTER 5and Haller (1977) compared groups of male and female adolescents who made sui-cide attempts and other emotionally disturbed adolescents without suicidal histories.The authors reported that MMPI scales 3 and 5 were significantly higher for maleattempters, whereas scale 9 elevations were associated with suicide attempts amongfemales. In contrast, Archer and Slesinger (1999)found single-scale elevations on scale2 or 8and coelevations on the 4-8and 4-9codetypes to be related to higher levels of sui-cidal ideation among adolescents. Spirito, Faust, Myers, and Bechtel (1988), however,found no significant differences in scale 2mean elevations between female adolescentsuicide attempters and a control group of female adolescents initially hospitalizedfor medical problems and referred for psychiatric consultation. Based on very simi-lar profiles produced by these two groups, in conjunction with the largely negativefindings in the adult literature, Spirito et al. concluded that "primary reliance on theMMPI alone to determine suicidal risk seems non-judicious" (p.210).High Scores on Scale2The following is a summary of descriptors for high scale 2 scores (T > 60):• Feelings of dissatisfaction, hopelessness, and unhappiness.• General apathy and lack of interest in activities.• Presence of guilt feelings, shame, and self-criticism.• Lack of self-confidence and a sense of inadequacy and pessimism.• Social withdrawal and social isolation.• A degree of emotional distress that may serve as a positive motivator for psy-chotherapy efforts.Low Scoreson Scale2The following are characteristics that have been associated with low scale 2 scores(T < 40):• Higher levels of intelligence and academic performance.• Freedom from depression, anxiety,and guilt.• Self-confidence and emotional stability.• The ability to function effectively across a variety of situations.• Alertness, activity, and competitiveness.• Rebelliousness, argumentativeness, irresponsibility, and manipulativeness(among adolescent psychiatric patients with low scale 2 scores).2-3/3-2 Codetype. There is substantial overlap in the correlates of the 2-3/3-2 code-type for adolescent and adult psychiatric patients. They are characteristically de-scribed as emotionally overcontrolled and unlikely to employ acting out as a primarydefense mechanism. They typically have histories that reflect a lack of involvement orinterest in relationships with others, and when relationships are established, they tendto have dependent characteristics. Adjectives such as passive,docile, and dependent arefrequently applied to individuals with the 2-3/3-2profile, and they are often describedas unassertive, inhibited, insecure, and self-doubting. Both adolescents and adultswith the 2-3/3-2 code are very achievement oriented and set high goals for their ownperformance. These goals are often unrealistic and appear to be a contributorto theirsense of inferiority and depression. Antisocial personality or psychopathicdiagnoses
  • 155. BASIC CLINICALSCALE AND CODETYPECORRELATES FOR ADOLESCENTS 141are markedly rare for adolescents and adults who produce the 2-3/3-2 codetype. Thereis also littleevidence ofthought disorder or the presence of schizophrenic or psychoticdiagnoses among these individuals. Defense mechanisms involving somatization andhypochondriasis appear to be central to the 2-3/3-2 codetype. In particular, weakness,fatigue, and dizziness appear to be common physical symptoms.Among adolescent patients,the 2-3/3-2 codetype isrelativelycommon and found in2.4% of males and 4.1%of females (see Table 5.5).Data on 2-3/3-2 adolescents indicatethat the majority of these adolescents were referred for treatment because of poorpeer relationships. These adolescents were seen as socially isolated and lonely. Theyhave few friends inside the school environment and are loners outside of academicsettings. The2-3/3-2 adolescent reported a relatively passive, compliant, and obedientchildhood that often involved an underinvolved father in a professional occupationand a mother who may have been overinvolved with these children. Sexual actingout and drug abuse do not appear to be high-frequency problem areas for theseadolescents, and 76%of the teenagers in the Marks et al. (1974) sample reported nohistory of drug abuse. In research by Archer and Klinefelter (1992), the MAC scaleraw scores for these adolescents were typically quite low. In the adult literature, the2-3/3-2 codetype is more prevalent among women, and the majority of patients withthis codetype are seen as psychoneurotic or reactivedepressive. The 2-3codetype wasthe modal pattern found for bulimia and anorexic adolescent patients in a study byCumella, Wall, and Kerr-Almeida(1999).2-4/4-2 Codetype. Among teenagers and adults, 2-4/4-2 profiles are typically pro-duced by individuals who have difficulty with impulsive controland often act withoutsufficient deliberation. They exhibit a marked disregard for accepted social standards,and problems with authority figures are manifested by inappropriate or antisocial be-haviors and actions. Hypochondriacal and somatic defense mechanisms are not typ-ically displayed by these individuals. Acting out, displacement, and externalizationappear to be primary defense mechanisms. There is often a history of legal violations,including incidents of arrest, legal convictions, and court actions. Indeed, one halfofthe adolescents in the Marks et al. (1974)sample had been placed on probation or heldin detention.In the adult and adolescent literatures, there are also frequent references to sub-stance abuse and alcohol problems associated with this codetype. In the adult liter-ature, the 2-4/4-2 profile is often the mean profile produced by samples of alcoholics(Greene & Garvin, 1988; Sutker & Archer, 1979). Marks et al. (1974) also noted thatadolescents with the 2-4/4-2 codetype reported a wide variety of drug use that in-cluded all pharmacological categories except narcotics. Indeed, Marks et al. foundpatterns indicating drug addiction as well as drug abuse among their 2-4/4-2 sampleof adolescents. The 2-4/4-2 codetype occurred with high frequency in the findingsshown in Table 5.5, reported for 5.0%of males and 3.3% of females in this sample. Inhospital settings, adolescents with the 2-4/4-2 profile were often found to be elope-ment risks. They also had frequent histories ofpromiscuous sexual behavior, truancy,and running away from home. In general, the 2-4/4-2 adolescents indicated that muchof their antisocial behaviors were attempts to escape or run away from what they per-ceived to be intolerable or hig
