Heavy Metal Music Preference

COMMENTARY by Simon Singer
I first had the idea to look at the relationship between
delinquency and music
preference after reading a New Yorker article in 1986 about Los
Angeles subur-
ban gangs. Within that excellent article by the journalist
William Barich (1986),
I saw a dearly articulated hypothesis. I didn't need to go much
further than that
to develop a theory about the possible effects of music on
delinquency.
It so happened that the next year I was asked if I wished to do a
"needs as-
sessment" for a large suburban community. There was New
York State agency
money available to conduct a survey for which I was given
discretion as to how
to define the proposed assessment. I wanted not only to meet
the agency's goal
of evaluating the concerns and interests of the town's youth, but
also to assess
the extent to which youth were involved in a variety of
delinquent behaviors.
The idea of linking music preference to self-reported
delinquency through
the survey technique came about when we needed to figure out
an incentive
that would lead to the participation of youth in the survey. We
received a good
deal on music coupons from a major retail record store in the
area. To close the
deal with the record store we asked that the store cashiers
record the actual
'
music that was purchased on the returned incentive coupon. The
survey also
asked music preference, and we felt that along with actual
music purcha e

We would like to see more research that takes into account what
goes on in
the daily lives of youth. Not only do schools classify youth, but
youth classify
themselves and they seem to do so with regard to music
preference. How
strongly they identify with various forms of music is a critical
part of how they
see themselves. Part of what is heard is heard for its
entertainment value alone,
and would bear little significance except for the fact that it is
associated with
other factors that attract youth to a particular kind of music.
The fact that we
were able to show that the relationship between heavy metal and
delinquency
is not direct would support those who argue that youth should
feel free to hear
any kind of music they want. Music alone is not enough to make
someone
delinquent according to our data .
. More research is needed on the cultural artifacts of our society
and the
delinqu~nt cond~ct of its youth. Such data are not easy to
obtain and require
us to thmk creat~vely about their measurement and analysis. It
is important to
go beyond any simple explanation for delinquent behavior, and
to apply the
advanced methodological tools of criminological research to
understanding the
complex causes of delinquency and crime.

from the dark-
ness where Hell hath no mercy and the screams of vengeance
echo on forever
only those who keep the faith shall escape the wrath of the
Metallian' ,,;
(p.123). Furthermore, Gr~ss's nonrepresentative sampling of
heavy metal music
also includes the unpublished lyrics " 'Blessed are the wicked,
cursed are the
weak,' "and" 'Your God is dead and now you die, Satan rules at
last' "(p. 124).
Heavy metal, as a cultural artifact, is not just communicated in
lyrical form.
It is also contained in distinct patterns of dress. For instance,
some fans display a
runic lightning bolt, borrowed from the heavy metal group
AC/DC's album
covers, Nazi Schutz Staffel and swastika designs, skeletons and
death heads
(Gross 1990, p. 125). Moreover, some of the behavior of heavy
metal perform-
ers communicates particular norms of conduct. As part of their
performance,
heavy metal stars, at times, will dramatize bizarre forms of
behavior. A widely
publicized example is when Ozzy Osbourne allegedly bit the
head of a bat in
the middle of a concert and then received rabies shots
afterwards (Barich 1986).
Although the act of biting a bat might be purely theatrical, it
can be considered
entertainment only by particular segments of society.
Similarly, there are actual acts of violence reported among
heavy metal fans.
In numerous concert tours, heavy metal means heavy security,
particularly in
the wake of high rates of arrest and physical injuries among
those attending the
concerts (Montgomery 1992). The security precautions that are
required at
heavy metal concerts are surely much greater than those
required at the phil-
harmonic or ballet. It seems obvious that a proportion of youth
present at heavy
metal concerts is different in their personal taste and behavior
from youth at-
tending the symphony. Moreover, parental concern about he.avy
metal has le.d
to attempts to require parental permission to purchase certam
types of music
that are considered offensive (see Arnett 1991).

In contrast to viewing the delinquent behavior of youth as either
height-
ened or suppressed by their preference for heavy metal, a more
complex model
would consider the effects of music in interaction with other
indicators of
delinquency. Heavy metal may be related to delinquent behavior
in interaction
with social control and peer group affiliations. The influence of
social control
and culture is emphasized in Barich's analysis of violent
delinquency among
suburban youth. Based on the interviews with Los Angeles
suburban gang
members and gang workers, Barich (1986) suggests that heavy
metal lyrics in-
crease the likelihood of delinquent behavior among naive youth
and youth low
in parental attachment and control.
An intelligent. kid mi~ht be able to react to heavy metal as
theater, but a dull
or confused kid took Its messages seriously. If a kid had no

ance, no filter between hi'm d th . . b"

Similarly, Willis's (1978) ethnographic study of British yo th . .
. . . u views music as
a means of mtegratmg adolesce?ts mto a c~mmon culture.
Within this general
youth culture, subg,roups are umt~d ~y their taste for particular
forms of music
(Willis 1990). Roes (1985) longitudinal survey data also show
that music is a
vehicle for the expres~ion of adoles_cent group values and
identity (p. 361). Ac-
cording to Roe, allegiance to particular youth groups is defined
by clothing,
hair styles, attitudes, models of behavior, and musical
preferences.
Thus a subcultural perspective leads us to suggest that patterns
of delinquent
peer group involvement vary by heavy metal preference. Heavy
metal music
should have no effect on the delinquent behavior of youth who
are isolated from
other delinquent youth. In the words of Sutherland's theory of
differential asso-
ciation, "the principal part of the learning of criminal behavior
occurs within
intimate personal groups" (Shoemaker 1990, p. 152). Therefore,
heavy metal
music should increase delinquent peer identification and
delinquent behavior.

METHOD
The Sample
In prino 19 7, w collected data on the deli~quent conduct of 705
suburban
hio-h chool y uth. The community from which we drew our
sample is largely
affluent.2 Of the population, 95% was classified as White. It
should also be
tre ed that the vast majority of heavy n1etal fans are White and
that they are not
onfined to particular urban or suburban parts of the United
States (Gross 1990).
We sampled 1,475 youth in public and ri te high chool from
school
board lists. After receiving the con ent of th mpled uth and their
parents, we
were able to complete interview with 7 5 uth durina n

19% preferred v1~tage. or c ass1c roe (e.g., The Who, Rush,

7% preferred
heavy metal groups. The heavy metal category included such
groups as Iron
Maiden, Motley Criie, Metallica, and AC/DC. 4
Stated music preference predicted the type of music youth
purchased. As an
incentive for completing the survey, each youth was provided
with a coupon re-
deemable for a tape or a record in a local chain of stores. 5
When the youth pur-
chased the record, the cashier coded the album or tape cassette
the youth
selected into specific music categories and placed these on the
coupons, which
were returned to us. Among the youth who said they preferred
heavy metal,
about half actually purchased a heavy metal album. If
preferences were ran-
domly related to purchases, we would expect only 7% to have
purchased a
heavy metal album. We use musical pref ere nee because we
have more complete
data than if we relied on actual purchases. We assume that
preference is related
to actual behavior, although it is quite possible that our heavy
metal measure
does not tap the extent to which youth actually listen to heavy
metal mus~c .
. In the following analysis, youth who listed a heavy metal
group as their fa-
vorite were coded into a heavy metal preference category (1 =
heavy metal
preference, 0 = others).

To test for interactions, we standa~~ize t e contmuous predictor
variables
(Aik
d West 1991; Jaccard, Turnsi, and Wan 1990). By standardizing
th
en an l . n· . . . e
predictor variables, the problem of mu tico meanty ~ testmg
interactions ~
substantially reduced. for example, the high:st correlat~on
coefficient between
the standardized variables (including interaction terms) is .39,
which is substan-
tially less than the correlations for unstandardized interaction
terms. We checked
the pattern of interactions by regressing delinquency on the raw
scores sepa-
rately for youth preferring heavy metal and non-heavy metal
music. The pattern
and size of coefficients produced virtually identical estimates,
so we feel confi-
dent in presenting the unstandardized coefficients based on
standardized values.
Also, we examined the pattern of interactions in separate
analyses, control-
ling for gender and age and type of offense, and found that the
results do not
differ significantly. Higher order interactions are not presented
here to simplify
the analysis, but they are available upon request. Furthermore,
our hypothesized
relationships are not specific to gender or age characteristics.
Table 1 presents the unstandardized regression coefficients and
their corre-
sponding significant levels for regression models with and
without interactions.
In .the main effects model without interactions, the significant
predictors of
delinquency are school marks, school importance, delinquent
friends, and heavy
metal preference. Once these variables are entered into the
equation, the impor:

way interactions with heavy metal preference, only parental
supervision and
school marks are significant in their effects on delinquency. The
two-way inter-
action for heavy metal preference and parental supervision is in
the expected di-
rection. But the interactive effect of school marks with heavy
metal on
delinquency is opposite from what was hypothesized. Moreover,
contrary to ex-
pectations, the interaction between delinquent friends and heavy
metal is not sig-
nificant. This suggests that the effects of delinquent peers on
delinquency are the
same for those youth who prefer heavy metal and youth
preferring other kinds
of music.
Table 2 displays the standardized effects of heavy metal
preference on delin-
quency for one standard deviation above and below the mean. In
interpreting
the coefficients in Table 1, recall that all variables are
standardized, with a mean
of zero and a standard deviation of one. The coefficients for the
"main effect "
efer to the effect of each variable on delinquency when all other
variables are
et at zero or their mean value. When all other variables are set
at their mean,
eavy metal preference has a standardized effect of .16 on
delinquency. Th co-
fficient for the interaction between heavy metal and parental
supervision is
.23. This means that for every standard deviation increase in
parental supervi-
ion, the effect of heavy metal preference on delinquency
decrease by -.2~.
en parental supervision and all other independent variables are
at the~r

SUMMARY
The results of this analysis provide mixed support for the
hypothesized interac-
tive effects of heavy metal preference. We found support for the
main effects of
heavy metal preference on delinquency controlling for other
important indica-
tors. In partial support of Barich's observation on the
relationship between
heavy metal _and delinquency, we found support for that part of
our hypothe~s
that dealt with parental supervision. Youth who preferred heavy
metal music
an_d were low m parental supervision had higher rates of
delinquency. However,

NOTES
1. Originally we had quoted directly from t~e Mode~ Criie
s~ng. But at the time of publi-
cation permission was denied by representatives of Motley
Crue. Thus we paraphrase the
song that Gross quotes. However, this illustrates part of the
difficulty in publishing research
on popular forms of culture.
2. Parents of youth surveyed were asked to indicate their
occupational class. Fathers are
largely in occupational positions of employers or managers
(73%). The remaining propor-
tion are equally divided among employee and self-employed
occupational positions. The
proportion of unemployed fathers in the survey is 6%.
3. The following music groups were classified as "heavy metal":
AC/DC, Black Sabbath,
Deep Purple, Dokken, Iron Maiden,Judas Priest, Mahles,
Metallica, Motley Criie, Primitive
Urges, Scorpions.
4· We realize tha~ there is some debate as to classification of
heavy metal groups. Such
ghroups can be delineated further into lighter forms of heavy

DISCUSSION QUESTIONS
1. What was the purpose of the
study? What was the primary
question that the authors wished
to address in the study?
As discussed by the authors, why
might one suspect that preference
r certain forms of music might
e related to delinquency?
3. Describe the data collection pro-
cess. How were the data that were
analyzed in the study collected?
4. According to the authors, ~oes lis-
tening to heavy metal m~s1c lead
to, or cause, delinquency. Why or
why not?
Elements of Research Design 103
the program (treatment) are unknown, the control group
offenders are
not being deprived. Once the effectiveness of the program is
deter-
mined, control group offenders can be admitted.19
Second, the classical experiment has the potential to encroach
upon
the decision-making authority of criminal justice agents. The
clear
solution here, as the Provo Experiment indicated, is to use
random
assignment after a decision is made. Surely, experimenters
cannot ex-
pect to randomly sentence people to prison or probation.
Modifica-
tions can be adopted which do not restrict the power of the
classical
experimental design while protecting the rights of individuals.
Third, there is the major issue of the feasibility of carrying out
an
experiment in the field.
The random assignment process must be structured to meet both
the demands of the classical experiment and the operations of
the
criminal justice system — in these two examples, sentencing by
judges
and arrest and other sanctions by police. It requires very close
coop-
eration between the operational agencies and the researchers.
Imple-
menting random assignment and maintaining it throughout the
pro-
cess can be problematic. Also, to repeat, the subjects selected
for study
must be eligible for treatment and the experimental and control
groups must be kept separate so that the integrity of the
treatment is
maintained.20 After all, exposure to the treatment should be the
only
difference between the two groups.
The Quasi-Experimental Design
The classical experiment is not the only form of research
design.
However, it serves as the point of departure for other designs
which
attempt to approximate its key features. The quasi-experimental
de-
sign is the mirror image of the classical experiment with one
key dif-
ference: the absence of random assignment. As previously
mentioned,
it is not always possible to implement the classical experiment.
Yet, it
is vital that a group is constructed to compare findings
generated by
the experimental group. Thus, a comparison group is selected
using
a method other than random assignment to insure that it is
compara-
ble to the experimental group.
Our example here is the evaluation of a prison-based treatment
pro-
gram for drug/alcohol abusing inmates.21 We need to find a
group of
inmates in the same prison who have the same problem, but who
were

never involved in the program in any way. After all, if we
select-
ed inmates who were excluded from the program, we would
commit
the error of selection bias. Similarly, if we chose inmates who
dropped
out of the program, the data would be contaminated because the
com-
parison group would have been exposed to the treatment. What
is left?
Adams’ suggests screening inmates who were considered for,
but for
reasons of their own, decided not to take part in the program —
a
self-drop group.22 Before such a group can be considered
however,
two important considerations must be checked out. First, the re-
searcher must be certain that such inmates were not thrown out
of the
program by project administrators (Beware of selection bias!).
Second,
you must be certain that these inmates were never enrolled in or
ex-
posed to the treatment (contamination of data problem). It
would also
be possible to check for eligible inmates who were simply
unaware of
the program. It is also possible to use a variation of the
matching tech-
nique (again the missing element is random assignment). Here,
the
experimenter would construct a comparison group which was
identi-
cal to the experimental group on a number of known variables
(i.e.,
age, race, prior record, present offense, education, marital
status, etc.).
In any event, since randomization was not utilized, it is
necessary to
record relevant personal and socio-demographic information on
such
inmates and compares them directly to the experimental group.
If dif-
ferences do exist, it would be necessary to control for them
statistical-
ly. Remember that the crucial issue here is that the experimental
and
comparison groups must be similar. The problem is that, even if
you
determine that the two groups are comparable, they may still
differ on
some important attribute which was beyond your means to
measure.
This is not a problem when random assignment is used, hence
the
power of the classical experimental design.
However, since it is not always possible to use random
assignment,
the quasi-experiment gives you another possibility to conduct
accurate
research. Quite simply, it may not be possible for you to do
anything
else and it is especially valuable when performing evaluation
research
(see Chapter Eleven).

comparison between the experimental group and another group
of
subjects. Typically, they are undertaken out of necessity
because they,
like the quasi-experimental design, offer a feasible alternative
to re-
search when the classical experiment is impossible to conduct.
The
chief problem is that the researcher is then unable to protect the
integrity of the research results and clearly state that they
reflect the
effect of the treatment and not some other force. They are not as
reli-
able as the classical experiment.
The first type of pre-experimental design is the one-shot case
study or the one group post test design. Here, measurements are
ob-
tained for one group after the treatment has been administered.
For
example, one could determine if a group of police officers
became
more sensitive to diversity issues after they went through a
diversity
training program. Their score on an examination would
determine if
they had learned the principles of diversity covered in the
training
program.
Probably the most common type of pre-experimental design is
the
before-after study (also known as the “one group pretest-
posttest de-
sign”). This design is simply the first half of the experimental
design.
The performance of the experimental group is recorded before
and
after the treatment is administered. It is the simplest design but,
due to
the absence of comparison, it fails to document the
effectiveness of the
treatment. It is commonly used when it is difficult to construct a
com-
parison or control group. For example, let’s say that we wish to
evalu-
ate the effectiveness of a neighborhood watch program in a
particular
neighborhood. Under a before and after study, we would
measure the
burglary rate (number of reported burglaries) before and then
after the
implementation of the neighborhood watch. Even if the burglary
rate
declined after the establishment of the neighborhood watch
program,
we would not be able to make a comparison to another
neighborhood
that did not have a neighborhood watch. Our only comparison is
to
our selected neighborhood before and then after the
neighborhood
watch began.
One way to attempt to provide this comparison is to use the
static
group comparison design. With this design, the number of
reported
burglaries in a neighborhood that has had a neighborhood watch
pro-
gram would be compared to the number of reported burglaries in
another neighborhood that did not have a neighborhood watch
pro-
gram. Here, the weakness is that, before the research is
conducted,

there is no examination to determine whether the two
neighborhoods
are comparable. The research conclusion is based upon
comparing the
impact upon each group to determine the effect of the treatment
on
one of them.
Cross-Sectional Design. A cross sectional design takes measure-
ments of subjects at a single time in their lives. The case study
is a
form of cross sectional design used in criminal justice research.
The
case can be an individual (a professional criminal), an event (a
police
strike), or a place (Alcatraz). This type of design is capable of
generat-
ing great quantities of descriptive information which can be
used by
policy makers. It is especially valuable in time of rapid change
because
it allows you to respond immediately to an historical event or a
nat-
ural experiment — i.e., the effect of a judicial order on the
operations
of a prison or a change in sentencing policy.23 Follow-up
recidivism
research on the former Kentucky death row inmates is an
example of
a natural experiment because their death sentences were
commuted
by a U.S. Supreme Court decision and they were later released
by the
parole board.24
Longitudinal Design. A longitudinal design is similar to the
cross sectional design with the key exception that measurements
are
taken at more than one point in time. One form of longitudinal
design
is the time series design. The time series design is one in which
the
treatment is introduced during a series of measurements on the
depen-
dent variable. All of the measurements are obtained from the
same
group. For example, a researcher could examine the deterrent
effect of
an execution by measuring the homicide rate in a state in the
months
prior to and following an execution. A sharp change in the trend
of
measurements on the dependent variable (the homicide rate)
immedi-
ately following the treatment (the execution) is assumed to be
attribut-
able to the treatment. Again, the comparison in results is within
the
experimental group only.
Another form of longitudinal design is a cohort study. It
examines
the behavior of a particular group over time. Cohorts are groups
con-
structed by the researcher that share some common experience
(i.e.,
involvement in the same program, graduating from the police
acade-
my in the same year). Their performance over time is then
recorded.
Wolfgang, Figlio, and Sellin (1972) tracked the delinquency
records of
a birth cohort of boys born in 1945 who lived in Philadelphia
from
their tenth to eighteenth birthdays. They discovered that 35
percent of

the boys had some type of contact with the police and that about
50
percent of the juveniles who commit an offense are likely to
commit
another.25
Regardless of the type of design, there are several threats to
validi-
ty that can affect the results of the study.
THREATS TO INTERNAL VALIDITY
Internal validity refers to ways in which the process of experi-
mentation may affect the research results. In other words, the
re-
searcher is then uncertain if the outcomes generated by the
research
are a result of the treatment or the way in which the experiment
was
conducted. In effect, the experiment becomes a treatment in
itself.
Cook and Campbell identified the following sources of internal
validity:26
1. History: events, in addition to the treatment, may occur be-
tween the pre and post tests which are beyond the control of the
experimenter. For example, Vito, Longmire, and Kenney (1984)
reported that, during their evaluation of a police burglary sup-
pression program, the state of California passed legislation re-
quiring a mandatory prison sentence for burglary.26 As a result,
the researchers were uncertain if the number of reported bur-
glaries recorded during the project were affected by the new
methods of police operations or due to the new law. Often, the
only thing which researchers can do when an historical event
occurs in the middle of their experiment is report that it oc-
curred and let the findings be interpreted accordingly.
2. Maturation refers to the processes operating within research
subjects as a function of the passage of time, including growing
older, growing hungrier or becoming more tired. Boredom
could also be a problem which could affect the behavior of the
research subjects. For example, Vito and Wilson (1988) con-
ducted a long term follow up of former death row inmates in
Kentucky whose sentence had been commuted to life in prison
as a result of the Furman v. Georgia (1972) decision. Was their
on
parole behavior due to the commutation of their death sentence
or due to aging?28

3. Testing concerns the effect of taking a test upon the scores of
a
second testing. If the same instrument is used for the pre and
post test, the subjects in the control group may be able to tease
out what the instrument is designed to measure (i.e., fear of
crime) and try to answer “the right way” rather than express
their own true feelings.
4. Instrumentation. If, upon repeated use, an instrument yields
the same results, it is considered to be reliable. But what would
happen if your instrument was altered somehow between the pre
and post tests? If there is some alteration in your instrument,
the
research results would be affected.
5. Statistical Regression is especially problematic when
research
subjects have been selected on the basis of their extreme scores
or attributes. “Regression toward the Mean” is a statistical phe-
nomenon which operates in nature. Any extreme attribute tends
to be balanced out over time. The problem, therefore, is that
extreme subjects tend to improve over time regardless of the
treatment. Their behavior or performance goes to the average
level for the group of subjects under study. For example, in his
book, The Future of Imprisonment, Morris (1974) proposed a
new
prison model which he would like to test using the “toughest
group of inmates.” Morris encouraged the use of a classical
experimental design to assign such inmates to his model institu-
tion. Clearly, statistical regression could be a threat to his pro-
posed experiment. If these inmates are so “bad” to begin with,
their behavior may simply regress toward the mean. If they did
improve, it would be difficult to say that the benefits were due
to
the new prison design.29
6. Experimental Mortality has to do with the loss of subjects
from your experimental and control groups. If large numbers of
subjects “drop out” for whatever reason, the groups may change
so much that they are no longer comparable. Thus, the major
strength of randomization is violated. Researchers conducting
recidivism studies have particular problems with mortality since
parolees are often mobile and do not leave forwarding address-
es and they often literally die while on supervision.30
7. Selection Biases: Remember, the groups must be comparable
to begin with. If techniques other than random assignment are
used, selection biases may affect the research results. Put
simply,

Elements of Research Design 109
you do not wish to compare apples to oranges. Researchers or
program officials should not put all the “best risks” in the
exper-
imental group and then compare them to a group of poor risks.
8. Interactions of the Above Problems. To make matters worse,
it is possible that your research can be affected by combinations
of the problems just mentioned. The design proposed by Morris
(1974) could not only be subject to problems due to statistical
re-
gression, but also due to maturation. And what would happen to
the research results if a riot or escape occurred during the study
(History)?
9. Causal Time Order. If somehow the time order between the
treatment and the measure of the dependent variable (post-test)
is fouled up, it is obvious that the causal relationship between
variables is no longer being tested.
10. Diffusion or Imitation of Treatment. If the respondents in
the
control group can communicate with the members of the exper-
imental group, they each may discover information intended for
the other group. Put simply, the physical closeness of the two
groups may render them equal by exposing them both to the
treatment. The Provo Experiment was plagued by this problem
since both the experimental and control (probation) groups were
supervised by the same probation office.
11. Compensatory Equalization of Treatments. When the exper-
imental treatment provides goods or services generally believed
to be desirable, the experimenter (or administrators in charge of
a project) may be sympathetic toward the control group and pro-
vide them with some compensatory benefit, such as special
attention. Of course, this special attention would thus become
another form of treatment and the original design would suffer.
12. Compensatory Rivalry by Respondents Receiving Less De-
sirable Treatments. When the assignment of persons to exper-
imental or control groups is made public (as is frequently re-
quired by ethical and legal considerations), competition may be
generated. In particular, the control group (the natural under-
dog) may be motivated to perform at the highest possible level.
13. Resentful Demoralization of Respondents Receiving Less
Desirable Treatments. This potential response is very much
related to rivalry. The control group may become demoralized

about the conditions of the research and thus perform more
poorly than the experimental group or get angry and revolt.
Other internal validity questions of special interest to criminal
jus-
tice researchers have been identified by Adams:31
14. Masking. Experimental treatments may have opposite
effects
upon different kinds of subjects. Vito (1982) has suggested that
it
is simply illogical to assume that all members of the experimen-
tal group were amenable to or served equally by a correctional
treatment program. Unless some measure of the effectiveness of
the treatment among the experimental subjects is included in the
study, masking could cloud the findings by failing to make such
differentiations in the experimental group.32
15. Contamination of Data. If the subjects in the control group
be-
come exposed to the treatment, their post-program performance
may be affected. This may have been one of the problems re-
garding the controversial Kansas City Preventive Patrol Experi-
ment.33 The treatment in this experiment was proactive police
patrolling — a test of deterrence theory. The experimental
neigh-
borhoods received proactive patrolling, the reactive (control)
areas underwent traditional patrolling (police responding to in-
coming calls for service and patrolling only the perimeter of the
beat or an adjacent proactive beat), while officers in the control
sections were to patrol as they normally would. The problem
was that the 15 neighborhoods in the study were adjacent to one
another. Was the treatment clearly isolated or did the neighbor-
hoods, in effect, all receive the same type of patrol?
16. “Erosion” of the Treatment Effect. The gradual or abrupt
dis-
appearance of performance superiority shown by the experi-
mental group in the early months after treatment may decrease
or simply wear off. This problem could be especially pro-
nounced if the researcher is following the performance of the
experimental subjects over a long period of time.
These problems are not insurmountable. They have been
presented
because the researcher must be aware of them in order to
combat
them. Some can be dealt with through the use of randomization
and
the classical experimental design (i.e., selection bias and
statistical
regression). Others can be handled by careful monitoring of the
con-
duct of the research. It is vital that the experimental and control

5 Heavy Metal Music Preference Delinquent Friends, Socia.docx

  • 1. 5 Heavy Metal Music Preference Delinquent Friends, Social ' Control, and Delinquency SIMON I. SINGER MURRAY LEVINE SUSYAN JOU COMMENTARY by Simon Singer I first had the idea to look at the relationship between delinquency and music preference after reading a New Yorker article in 1986 about Los Angeles subur- ban gangs. Within that excellent article by the journalist William Barich (1986), I saw a dearly articulated hypothesis. I didn't need to go much further than that to develop a theory about the possible effects of music on delinquency. It so happened that the next year I was asked if I wished to do a "needs as- sessment" for a large suburban community. There was New York State agency money available to conduct a survey for which I was given discretion as to how
  • 2. to define the proposed assessment. I wanted not only to meet the agency's goal of evaluating the concerns and interests of the town's youth, but also to assess the extent to which youth were involved in a variety of delinquent behaviors. The idea of linking music preference to self-reported delinquency through the survey technique came about when we needed to figure out an incentive that would lead to the participation of youth in the survey. We received a good deal on music coupons from a major retail record store in the area. To close the deal with the record store we asked that the store cashiers record the actual ' music that was purchased on the returned incentive coupon. The survey also asked music preference, and we felt that along with actual music purcha e Sourcr:Journal i?f R~earch i11 Cri111e and Delinquency. Vol. JO, N .

We would like to see more research that takes into account what goes on in the daily lives of youth. Not only do schools classify youth, but youth classify themselves and they seem to do so with regard to music preference. How strongly they identify with various forms of music is a critical part of how they see themselves. Part of what is heard is heard for its entertainment value alone, and would bear little significance except for the fact that it is associated with other factors that attract youth to a particular kind of music. The fact that we were able to show that the relationship between heavy metal and delinquency is not direct would support those who argue that youth should feel free to hear any kind of music they want. Music alone is not enough to make someone delinquent according to our data . . More research is needed on the cultural artifacts of our society and the delinqu~nt cond~ct of its youth. Such data are not easy to obtain and require us to thmk creat~vely about their measurement and analysis. It

Furthermore, Gr~ss's nonrepresentative sampling of heavy metal music also includes the unpublished lyrics " 'Blessed are the wicked, cursed are the weak,' "and" 'Your God is dead and now you die, Satan rules at last' "(p. 124).
  • 8. Heavy metal, as a cultural artifact, is not just communicated in lyrical form. It is also contained in distinct patterns of dress. For instance, some fans display a runic lightning bolt, borrowed from the heavy metal group AC/DC's album covers, Nazi Schutz Staffel and swastika designs, skeletons and death heads (Gross 1990, p. 125). Moreover, some of the behavior of heavy metal perform- ers communicates particular norms of conduct. As part of their performance, heavy metal stars, at times, will dramatize bizarre forms of behavior. A widely publicized example is when Ozzy Osbourne allegedly bit the head of a bat in the middle of a concert and then received rabies shots afterwards (Barich 1986). Although the act of biting a bat might be purely theatrical, it can be considered entertainment only by particular segments of society. Similarly, there are actual acts of violence reported among heavy metal fans. In numerous concert tours, heavy metal means heavy security, particularly in the wake of high rates of arrest and physical injuries among those attending the concerts (Montgomery 1992). The security precautions that are required at heavy metal concerts are surely much greater than those required at the phil- harmonic or ballet. It seems obvious that a proportion of youth present at heavy metal concerts is different in their personal taste and behavior

Moreover, parental concern about he.avy metal has le.d to attempts to require parental permission to purchase certam types of music that are considered offensive (see Arnett 1991). *"Defenders of the Faith" by G.

In contrast to viewing the delinquent behavior of youth as either height- ened or suppressed by their preference for heavy metal, a more complex model would consider the effects of music in interaction with other indicators of delinquency. Heavy metal may be related to delinquent behavior in interaction with social control and peer group affiliations. The influence of social control and culture is emphasized in Barich's analysis of violent delinquency among suburban youth. Based on the interviews with Los Angeles suburban gang members and gang workers, Barich (1986) suggests that heavy metal lyrics in- crease the likelihood of delinquent behavior among naive youth and youth low in parental attachment and control. An intelligent. kid mi~ht be able to react to heavy metal as theater, but a dull or confused kid took Its messages seriously.

  • 14. Within this general youth culture, subg,roups are umt~d ~y their taste for particular forms of music (Willis 1990). Roes (1985) longitudinal survey data also show that music is a vehicle for the expres~ion of adoles_cent group values and identity (p. 361). Ac- cording to Roe, allegiance to particular youth groups is defined by clothing, hair styles, attitudes, models of behavior, and musical preferences. Thus a subcultural perspective leads us to suggest that patterns of delinquent peer group involvement vary by heavy metal preference. Heavy metal music should have no effect on the delinquent behavior of youth who are isolated from other delinquent youth. In the words of Sutherland's theory of differential asso- ciation, "the principal part of the learning of criminal behavior occurs within intimate personal groups" (Shoemaker 1990, p. 152). Therefore, heavy metal music should increase delinquent peer identification and delinquent behavior.

The heavy metal category included such groups as Iron Maiden, Motley Criie, Metallica, and AC/DC. 4 Stated music preference predicted the type of music youth purchased. As an incentive for completing the survey, each youth was provided with a coupon re- deemable for a tape or a record in a local chain of stores. 5 When the youth pur- chased the record, the cashier coded the album or tape cassette the youth selected into specific music categories and placed these on the coupons, which were returned to us. Among the youth who said they preferred heavy metal, about half actually purchased a heavy metal album. If preferences were ran- domly related to purchases, we would expect only 7% to have purchased a heavy metal album. We use musical pref ere nee because we have more complete data than if we relied on actual purchases. We assume that preference is related to actual behavior, although it is quite possible that our heavy

We checked the pattern of interactions by regressing delinquency on the raw scores sepa- rately for youth preferring heavy metal and non-heavy metal music. The pattern and size of coefficients produced virtually identical estimates, so we feel confi- dent in presenting the unstandardized coefficients based on standardized values. Also, we examined the pattern of interactions in separate analyses, control- ling for gender and age and type of offense, and found that the results do not differ significantly. Higher order interactions are not presented here to simplify the analysis, but they are available upon request. Furthermore, our hypothesized relationships are not specific to gender or age characteristics. Table 1 presents the unstandardized regression coefficients and their corre- sponding significant levels for regression models with and without interactions. In .the main effects model without interactions, the significant predictors of delinquency are school marks, school importance, delinquent friends, and heavy metal preference.

Moreover, contrary to ex- pectations, the interaction between delinquent friends and heavy metal is not sig- nificant. This suggests that the effects of delinquent peers on delinquency are the same for those youth who prefer heavy metal and youth preferring other kinds of music. Table 2 displays the standardized effects of heavy metal preference on delin- quency for one standard deviation above and below the mean. In interpreting the coefficients in Table 1, recall that all variables are standardized, with a mean of zero and a standard deviation of one. The coefficients for the "main effect " efer to the effect of each variable on delinquency when all other variables are et at zero or their mean value. When all other variables are set at their mean, eavy metal preference has a standardized effect of .16 on delinquency.

We found support for the main effects of heavy metal preference on delinquency controlling for other important indica- tors. In partial support of Barich's observation on the relationship between heavy metal _and delinquency, we found support for that part of our hypothe~s that dealt with parental supervision.

What was the primary question that the authors wished to address in the study? As discussed by the authors, why might one suspect that preference r certain forms of music might e related to delinquency? 3. Describe the data collection pro- cess. How were the data that were analyzed in the study collected? 4. According to the authors, ~oes lis- tening to heavy metal m~s1c lead to, or cause, delinquency. Why or why not? Elements of Research Design 103 the program (treatment) are unknown, the control group offenders are
  • 36. not being deprived. Once the effectiveness of the program is deter- mined, control group offenders can be admitted.19 Second, the classical experiment has the potential to encroach upon the decision-making authority of criminal justice agents. The clear solution here, as the Provo Experiment indicated, is to use random assignment after a decision is made. Surely, experimenters cannot ex- pect to randomly sentence people to prison or probation. Modifica- tions can be adopted which do not restrict the power of the classical experimental design while protecting the rights of individuals. Third, there is the major issue of the feasibility of carrying out an experiment in the field. The random assignment process must be structured to meet both the demands of the classical experiment and the operations of the criminal justice system — in these two examples, sentencing by judges and arrest and other sanctions by police. It requires very close coop- eration between the operational agencies and the researchers. Imple- menting random assignment and maintaining it throughout the pro- cess can be problematic. Also, to repeat, the subjects selected for study must be eligible for treatment and the experimental and control
  • 37. groups must be kept separate so that the integrity of the treatment is maintained.20 After all, exposure to the treatment should be the only difference between the two groups. The Quasi-Experimental Design The classical experiment is not the only form of research design. However, it serves as the point of departure for other designs which attempt to approximate its key features. The quasi-experimental de- sign is the mirror image of the classical experiment with one key dif- ference: the absence of random assignment. As previously mentioned, it is not always possible to implement the classical experiment. Yet, it is vital that a group is constructed to compare findings generated by the experimental group. Thus, a comparison group is selected using a method other than random assignment to insure that it is compara- ble to the experimental group. Our example here is the evaluation of a prison-based treatment pro- gram for drug/alcohol abusing inmates.21 We need to find a group of inmates in the same prison who have the same problem, but who were Co

  • 41. 104 Introduction to Criminal Justice Research Methods never involved in the program in any way. After all, if we select- ed inmates who were excluded from the program, we would commit the error of selection bias. Similarly, if we chose inmates who dropped out of the program, the data would be contaminated because the com- parison group would have been exposed to the treatment. What is left? Adams’ suggests screening inmates who were considered for, but for reasons of their own, decided not to take part in the program — a self-drop group.22 Before such a group can be considered however, two important considerations must be checked out. First, the re- searcher must be certain that such inmates were not thrown out of the program by project administrators (Beware of selection bias!). Second, you must be certain that these inmates were never enrolled in or ex- posed to the treatment (contamination of data problem). It would also be possible to check for eligible inmates who were simply unaware of the program. It is also possible to use a variation of the matching tech- nique (again the missing element is random assignment). Here, the experimenter would construct a comparison group which was identi-
  • 42. cal to the experimental group on a number of known variables (i.e., age, race, prior record, present offense, education, marital status, etc.). In any event, since randomization was not utilized, it is necessary to record relevant personal and socio-demographic information on such inmates and compares them directly to the experimental group. If dif- ferences do exist, it would be necessary to control for them statistical- ly. Remember that the crucial issue here is that the experimental and comparison groups must be similar. The problem is that, even if you determine that the two groups are comparable, they may still differ on some important attribute which was beyond your means to measure. This is not a problem when random assignment is used, hence the power of the classical experimental design. However, since it is not always possible to use random assignment, the quasi-experiment gives you another possibility to conduct accurate research. Quite simply, it may not be possible for you to do anything else and it is especially valuable when performing evaluation research (see Chapter Eleven). Other Types of Research Designs

Typically, they are undertaken out of necessity because they, like the quasi-experimental design, offer a feasible alternative to re- search when the classical experiment is impossible to conduct. The chief problem is that the researcher is then unable to protect the integrity of the research results and clearly state that they reflect the effect of the treatment and not some other force. They are not as reli- able as the classical experiment. The first type of pre-experimental design is the one-shot case study or the one group post test design. Here, measurements are ob- tained for one group after the treatment has been administered. For example, one could determine if a group of police officers became more sensitive to diversity issues after they went through a diversity training program. Their score on an examination would determine if
  • 47. they had learned the principles of diversity covered in the training program. Probably the most common type of pre-experimental design is the before-after study (also known as the “one group pretest- posttest de- sign”). This design is simply the first half of the experimental design. The performance of the experimental group is recorded before and after the treatment is administered. It is the simplest design but, due to the absence of comparison, it fails to document the effectiveness of the treatment. It is commonly used when it is difficult to construct a com- parison or control group. For example, let’s say that we wish to evalu- ate the effectiveness of a neighborhood watch program in a particular neighborhood. Under a before and after study, we would measure the burglary rate (number of reported burglaries) before and then after the implementation of the neighborhood watch. Even if the burglary rate declined after the establishment of the neighborhood watch program, we would not be able to make a comparison to another neighborhood that did not have a neighborhood watch. Our only comparison is to our selected neighborhood before and then after the neighborhood
  • 48. watch began. One way to attempt to provide this comparison is to use the static group comparison design. With this design, the number of reported burglaries in a neighborhood that has had a neighborhood watch pro- gram would be compared to the number of reported burglaries in another neighborhood that did not have a neighborhood watch pro- gram. Here, the weakness is that, before the research is conducted, Co py ri gh t © 2 00 8. C ha rl es C T ho ma s. A ll r

The research conclusion is based upon comparing the impact upon each group to determine the effect of the treatment on one of them. Cross-Sectional Design. A cross sectional design takes measure- ments of subjects at a single time in their lives. The case study is a form of cross sectional design used in criminal justice research. The case can be an individual (a professional criminal), an event (a police strike), or a place (Alcatraz). This type of design is capable of generat- ing great quantities of descriptive information which can be
  • 52. used by policy makers. It is especially valuable in time of rapid change because it allows you to respond immediately to an historical event or a nat- ural experiment — i.e., the effect of a judicial order on the operations of a prison or a change in sentencing policy.23 Follow-up recidivism research on the former Kentucky death row inmates is an example of a natural experiment because their death sentences were commuted by a U.S. Supreme Court decision and they were later released by the parole board.24 Longitudinal Design. A longitudinal design is similar to the cross sectional design with the key exception that measurements are taken at more than one point in time. One form of longitudinal design is the time series design. The time series design is one in which the treatment is introduced during a series of measurements on the depen- dent variable. All of the measurements are obtained from the same group. For example, a researcher could examine the deterrent effect of an execution by measuring the homicide rate in a state in the months prior to and following an execution. A sharp change in the trend of measurements on the dependent variable (the homicide rate) immedi-
  • 53. ately following the treatment (the execution) is assumed to be attribut- able to the treatment. Again, the comparison in results is within the experimental group only. Another form of longitudinal design is a cohort study. It examines the behavior of a particular group over time. Cohorts are groups con- structed by the researcher that share some common experience (i.e., involvement in the same program, graduating from the police acade- my in the same year). Their performance over time is then recorded. Wolfgang, Figlio, and Sellin (1972) tracked the delinquency records of a birth cohort of boys born in 1945 who lived in Philadelphia from their tenth to eighteenth birthdays. They discovered that 35 percent of Co py ri gh t © 2 00 8. C ha rl

  • 57. THREATS TO INTERNAL VALIDITY Internal validity refers to ways in which the process of experi- mentation may affect the research results. In other words, the re- searcher is then uncertain if the outcomes generated by the research are a result of the treatment or the way in which the experiment was conducted. In effect, the experiment becomes a treatment in itself. Cook and Campbell identified the following sources of internal validity:26 1. History: events, in addition to the treatment, may occur be- tween the pre and post tests which are beyond the control of the experimenter. For example, Vito, Longmire, and Kenney (1984) reported that, during their evaluation of a police burglary sup- pression program, the state of California passed legislation re- quiring a mandatory prison sentence for burglary.26 As a result, the researchers were uncertain if the number of reported bur- glaries recorded during the project were affected by the new methods of police operations or due to the new law. Often, the only thing which researchers can do when an historical event occurs in the middle of their experiment is report that it oc- curred and let the findings be interpreted accordingly. 2. Maturation refers to the processes operating within research subjects as a function of the passage of time, including growing older, growing hungrier or becoming more tired. Boredom could also be a problem which could affect the behavior of the research subjects. For example, Vito and Wilson (1988) con- ducted a long term follow up of former death row inmates in Kentucky whose sentence had been commuted to life in prison
  • 58. as a result of the Furman v. Georgia (1972) decision. Was their on parole behavior due to the commutation of their death sentence or due to aging?28 Co py ri gh t © 2 00 8. C ha rl es C T ho ma s. A ll r ig ht s re se rv ed . Ma

Testing concerns the effect of taking a test upon the scores of a second testing. If the same instrument is used for the pre and post test, the subjects in the control group may be able to tease out what the instrument is designed to measure (i.e., fear of crime) and try to answer “the right way” rather than express their own true feelings. 4. Instrumentation. If, upon repeated use, an instrument yields the same results, it is considered to be reliable. But what would happen if your instrument was altered somehow between the pre and post tests? If there is some alteration in your instrument, the research results would be affected. 5. Statistical Regression is especially problematic when research subjects have been selected on the basis of their extreme scores or attributes. “Regression toward the Mean” is a statistical phe- nomenon which operates in nature. Any extreme attribute tends to be balanced out over time. The problem, therefore, is that extreme subjects tend to improve over time regardless of the treatment. Their behavior or performance goes to the average level for the group of subjects under study. For example, in his book, The Future of Imprisonment, Morris (1974) proposed a new prison model which he would like to test using the “toughest
  • 62. group of inmates.” Morris encouraged the use of a classical experimental design to assign such inmates to his model institu- tion. Clearly, statistical regression could be a threat to his pro- posed experiment. If these inmates are so “bad” to begin with, their behavior may simply regress toward the mean. If they did improve, it would be difficult to say that the benefits were due to the new prison design.29 6. Experimental Mortality has to do with the loss of subjects from your experimental and control groups. If large numbers of subjects “drop out” for whatever reason, the groups may change so much that they are no longer comparable. Thus, the major strength of randomization is violated. Researchers conducting recidivism studies have particular problems with mortality since parolees are often mobile and do not leave forwarding address- es and they often literally die while on supervision.30 7. Selection Biases: Remember, the groups must be comparable to begin with. If techniques other than random assignment are used, selection biases may affect the research results.

Researchers or program officials should not put all the “best risks” in the exper- imental group and then compare them to a group of poor risks. 8. Interactions of the Above Problems. To make matters worse, it is possible that your research can be affected by combinations of the problems just mentioned. The design proposed by Morris (1974) could not only be subject to problems due to statistical
  • 66. re- gression, but also due to maturation. And what would happen to the research results if a riot or escape occurred during the study (History)? 9. Causal Time Order. If somehow the time order between the treatment and the measure of the dependent variable (post-test) is fouled up, it is obvious that the causal relationship between variables is no longer being tested. 10. Diffusion or Imitation of Treatment. If the respondents in the control group can communicate with the members of the exper- imental group, they each may discover information intended for the other group. Put simply, the physical closeness of the two groups may render them equal by exposing them both to the treatment. The Provo Experiment was plagued by this problem since both the experimental and control (probation) groups were supervised by the same probation office. 11. Compensatory Equalization of Treatments. When the exper- imental treatment provides goods or services generally believed to be desirable, the experimenter (or administrators in charge of a project) may be sympathetic toward the control group and pro- vide them with some compensatory benefit, such as special attention. Of course, this special attention would thus become another form of treatment and the original design would suffer. 12. Compensatory Rivalry by Respondents Receiving Less De- sirable Treatments. When the assignment of persons to exper- imental or control groups is made public (as is frequently re- quired by ethical and legal considerations), competition may be generated. In particular, the control group (the natural under- dog) may be motivated to perform at the highest possible level. 13. Resentful Demoralization of Respondents Receiving Less

Other internal validity questions of special interest to criminal jus- tice researchers have been identified by Adams:31 14. Masking. Experimental treatments may have opposite effects upon different kinds of subjects. Vito (1982) has suggested that it is simply illogical to assume that all members of the experimen- tal group were amenable to or served equally by a correctional treatment program. Unless some measure of the effectiveness of the treatment among the experimental subjects is included in the study, masking could cloud the findings by failing to make such differentiations in the experimental group.32 15. Contamination of Data. If the subjects in the control group be- come exposed to the treatment, their post-program performance may be affected. This may have been one of the problems re- garding the controversial Kansas City Preventive Patrol Experi- ment.33 The treatment in this experiment was proactive police patrolling — a test of deterrence theory. The experimental neigh- borhoods received proactive patrolling, the reactive (control) areas underwent traditional patrolling (police responding to in- coming calls for service and patrolling only the perimeter of the
  • 71. beat or an adjacent proactive beat), while officers in the control sections were to patrol as they normally would. The problem was that the 15 neighborhoods in the study were adjacent to one another. Was the treatment clearly isolated or did the neighbor- hoods, in effect, all receive the same type of patrol? 16. “Erosion” of the Treatment Effect. The gradual or abrupt dis- appearance of performance superiority shown by the experi- mental group in the early months after treatment may decrease or simply wear off. This problem could be especially pro- nounced if the researcher is following the performance of the experimental subjects over a long period of time. These problems are not insurmountable. They have been presented because the researcher must be aware of them in order to combat them. Some can be dealt with through the use of randomization and the classical experimental design (i.e., selection bias and statistical regression). Others can be handled by careful monitoring of the con- duct of the research. It is vital that the experimental and control Co py ri gh t © 2 00 8. C
