Avoiding A Grand Failure

  1. 1. David DeGeest<br />06J:278 Staffing<br />April 13, 2010<br />SJTs: Avoiding a Grand Failure<br />
  2. 2. Why are people so interested?<br />The Big Picture of SJT lit<br />
  3. 3. The claims about SJTs<br />“They seem to represent psychometric alchemy” (Landy, 2007).<br />Adverse impact is down, validity up<br />Assessees like them<br />Seem to address relevant KSAOs<br />They assess soft skills and tacit knowledge<br />They provide incremental validity above GMA and personality for predicting college GPA (Oswald et al., 2004)<br />Some SJTs have demonstrated criterion-related validities as high as r=.36 (Pereira and Harve, 1999)<br />They measure tacit knowledge and “non-academic intelligence” (Sternberg et al., 1995)<br />
  4. 4. What is an SJT?<br />Situational Judgment Tests (SJTs) or Inventories (SJIs) are psychological tests which offer respondents realistic, hypothetical scenarios and ask for an appropriate response.<br />SJTs are often-identified as a type of low-fidelity situation (Motowildo, 1990).<br />SJTs can be designed to be predictive of job performance, managerial ability, integrity, personality, and apparently other measures or constructs.<br />
  5. 5. Example of an SJT item from Becker (2005)<br />11. You’re retiring from a successful business that you started, and must now decide who will replace you. Two of your children want the position and would probably do a fine job. However, three non-family employees are more qualified. Who would you most likely put in charge?<br />A. The best performing non-family member, because the most qualified person deserves the job. <br />B. The lowest performing non-family member, because this won’t hurt your children’s feelings. <br />C. The highest performing child, because you have the right to do what is best for your kids. <br />D. The child you love the most, as long as he or she is able to do the job. <br />
  6. 6. History of SJTs<br />First recorded SJT: George Washington University Social Intelligence Test (1926)<br />Some usage during WWII by military psychologists<br />(1990): Motowildo’s research resurrected interest in SJTs<br />Idea of the “low fidelity simulation”<br />Commonly used now in industry as “customized” tool for organizations, consultants, etc.<br />Takeaway: There is a lot of perceived promise and sunk cost in SJT research.<br />
  7. 7. What the heck is an SJT?<br />Construct Validity and the Development of SJTs<br />
  8. 8. Item Characteristics <br />McDaniel et al (2005) claims that SJTs have eight differentiating characteristics:<br />Test fidelity<br />Stem length<br />Stem complexity<br />Stem comprehensibility<br />Nested stems<br />Nature of responses <br />Response instructions<br />Degree of item heterogeneity<br />No proscribed standards to develop an SJT<br />
  9. 9. Item Characteristics<br />Examples of response options:<br />What is the best answer?<br />What would you most likely do?<br />Rate each response for effectiveness<br />Rate each response on likelihood you would engage in behavior<br />Knowledge v. Behavioral Tendency<br />Dichotomization Issue<br />
  10. 10. Item Characteristics and Construct Validity<br />Construct Heterogeneity<br />Most items tend to correlate with GMA, Agreeableness, Conscientiousness, or Emotional Stability (McDaniel, 2005)<br />Ployhart and Erhart (2003) notes that multiple constructs measured with SJTs makes it hard to measure differences across studies<br />Takeaway: SJTs are best described as a method, not a construct (Schmitt & Chan, 2006)<br />
  11. 11. Exciting finds from research on SJTs<br />The promise of SJTs<br />
  12. 12. Generalizability<br />McDaniel et al. (2007) meta-analytically demonstrated SJTs have incremental validity of<br />.03 to .05 over GMA<br />.06 to .07 over Big Five<br />.01 to .02 over GMA/Big Five composite<br />McDaniel et al. (2001) showed that SJTs are generalizable as predictors of job performance<br />90% CV did not contain zero in the meta<br />Potosky et al. (2004) showed that a .84 score-equivalence correlation between an SJT administered via paper-and-pencil and the Internet<br />No effects based on beliefs in computer efficacy<br />Takeaway: multiple metas have demonstrated the generalizability of SJTs in predicting job performance.<br />
  13. 13. Variability in SJTs<br />Lievens and Sackett (2006) showed that video-based SJTs for interpersonal skills have more validity than written SJTs.<br />McDaniel et al. (2007) showed that reliabilities for SJTs can range from .63 to .88<br />The meta refers to alpha, but other reliability measures matter<br />Takeaway: Effects of variations in level of fidelity offer interesting possibilities for research.<br />
  14. 14. Assessment Reactions and Face Validity<br />Chan & Schmitt (1997) showed that B-W differences in test performance and face validity reactions were lower for video-based SJTs than pencil-and-paper tests<br />Race X Method interaction attributable to reading comprehension differences in subgroups<br />Increasing fidelity increased mean performance on SJT<br />Chan (1997) showed that paper-and-pencil SJTs are more consistent with beliefs, values, and expectations of whites.<br />Moving to video-based SJT increased validity perceptions for both whites and blacks<br />Bauer and Truxillo (2006) asserts that SJTs always have better face validity than do cognitive and personality measures.<br />Takeaways: SJTs are useful in terms of face validity and justice perceptions, particularly high-fidelity (video) simulations.<br />
  15. 15. The trouble with…<br />Problems with SJTs<br />
  16. 16. The problem of g<br /><ul><li>Nguyen (2005) Found that knowledge instruction SJT scores correlated .56 with GMA and behavioral instructions correlated .38 with GMA.
  17. 17. Peeters and Lievens (2005) found that faking-good instructions produced differences in means and criterion-related validities across subgroups.
  18. 18. “Specifically, the fakability of SJTs might depend on their correlation with one particular construct, namely, cognitive ability (see Nguyen &McDaniel, 2001).” (p.73)
  19. 19. Schmidt and Hunter (2003) found low discriminant validity between SJTs and job knowledge tests.
  20. 20. Retesting Issue
  21. 21. “If subgroup differences on a test exist, policies that permit retests by candidates who were unsuccessful on the test might inflate calculations of adverse impact.” (Lievens et al., 2005, p. 1005)</li></ul>Takeaway: If the degree of fakibility of an SJT depends on its GMA load, SJTs might just be contaminated g tests or low-reliability job knowledge tests.<br />
  22. 22. Faking<br />Nguyen et al. (2005) found that d=.34 for honest instructions and d=.15 for faking<br />Ployhart and Erhart (2003) also note that behavioral response instructions are both more prone to faking and have problematic more reliability issues<br />Hooper et al. (2006) notes that the fragmentation of the literature has made a meta-analytic study of this issue impossible.<br />
  23. 23. Response Instructions<br />Ployhart and Erhart (2003) found that response instructions had dramatic effects on validity, reliability, and performance for SJTs<br />Showed that dimensionality of an SJT is crucial to determining the reliability estimate to use.<br />McDaniel et al. (2007) found meaningful differences between means for tests with different behavioral and knowledge instructions.<br />Lievens and Sackett (2009) found no meaningful differences between means in a high-stakes testing environment with med school applicants.<br />Last two studies found that knowledge instructions for an SJT increased the scores’ correlation with a GMA measure<br />Takeaway: meta-analytic integration of these results is needed, but the primary research has yet to support this.<br />
  24. 24. What is the reliability for an SJT?<br />Bess (2001) points out the elephant in the room:<br />“SJTs by definition are multidimensional and therefore internal consistency is not an appropriate measure of reliability” (p.29)<br />Schmitt and Chan (1997) also notes this problem.<br />Examples of reliability estimates:<br />Ployhart and Erhart (2003) Used split-half estimates to get .67 and .68 reliabilities.<br />Lievens and Sackett (2009) found low alphas for their SJT (.55-.56)<br />Lievens and Sackett (2007) noted generating alternate forms is difficult for SJTs, given the contextual specificity of items.<br />This means parallel forms reliability is a non-practical measure.<br />Takeaway: no one is quite sure how to systematically assess reliabilities for SJT measures<br />
  25. 25. What do we know about SJTs?<br />Conclusions<br />
  26. 26. Things we know fairly clearly<br />SJTs are primarily a method, not a construct.<br />SJTs have demonstrated generalizable meta-analytic incremental validity over GMA and Big 5 single and composite measures in predicting job performance<br />Most SJTs are correlated with GMA to a varying extent and share some benefits and disadvantages with GMA<br />SJTs often correlate with the Big 3<br />
  27. 27. McDaniel et al. (2006) integrated model for SJT <br />
  28. 28. Where do researchers go from here? Practitioners?<br />Future Directions for SJTs<br />
  29. 29. Ployhart & Weekly (2006) Agenda for Research<br />Construct Validity<br />Correlates are known, but nomological net uncertain<br />SJTs targeted to constructs: the “holy grail” (p.348)<br />What exactly is “judgment?”<br />Understanding SJT structure<br />How do we build SJTs to get construct homogeneity?<br />How do we enhance the reliability of these measures?<br />More Experimentation/Micro Research<br />Correlation studies and metas show generalizability<br />Experimental studies can enhance understanding<br />
  30. 30. Ployhart & Weekly (2006) Agenda for Research<br />Need for Theoretical Development<br />Will help to integrate SJTs in mainline I/O research<br />Theory of situation perception and judgment research<br />The limits of SJTs<br />Little is known about applicant conditions for SJTs<br />Generalizability in international contexts?<br />Expansion of org context for SJTs<br />Possibility of use in training and development contexts (Fritzche et al., 2006)<br />Use in team contexts (Mumford et al., 2006)<br />
  31. 31. Other possibilities<br />Personality and Self-Reports<br />Ployhart and Ryan (2004) proposed integrating personality measures with an SJT to predict customer service orientation<br />Hogan (2005)’s work suggests that it may be possible to build a conscientiousness measure via an SJT that is more resistant to faking than current self-reports.<br />Bledow et Freese (2003)’s work also supports using SJTs to create non-self-report measures of constructs like personal drive or initiative.<br />Teams<br />Mumford et. al (2006)’s work suggests building an SJT that would ably predict a “team player” mentality.<br />
