DECOMPOSING THE PEER EFFECT ON ADOLESCENT SUBSTANCE USE: MEDIATION,NONLINEARITY, AND DIFFERENTIAL NONLINEARITY*

Although the correlation between peer delinquency and delinquency is one of the most consistently demonstrated findings in delinquency research, researchers have focused primarily on the direct, linear, and additive effects of peers in statistical models, rather than on empirically modeling mediating, nonlinear, and moderating processes that are specified by theory. To address these issues, we measure respondent delinquency and peer delinquency with illegal substance use and then decompose the effect of peer substance use on self‐reported substance use. Logistic hierarchical models on a sample of adolescents from the Project on Human Development in Chicago Neighborhoods (PHDCN) indicate that the effect of peer substance use on self‐reported substance use is partially mediated by perceptions of the health risks of substance use. In addition, the direct statistical effect of peers is nonlinear: On average, the peer effect decreases at higher values of peer substance use, which is consistent with a “saturation” effect. We also find that the functional form of the peer substance use/substance use relationship is dependent on the neighborhood context. In neighborhoods with more opportunities for crime, the peer effect is initially strong but decreases as peer substance use increases, which is consistent with a saturation effect. Conversely, in neighborhoods with fewer opportunities for crime, the effect of peers is initially small, but as delinquent peer associations increase, the peer effect increases multiplicatively.     

Community structure and drug use: From a social disorganization perspective

Social disorganization theory experienced a relative resurgence in the criminological literature during the 1980s. This new generation of research has expanded the work of Shaw and McKay by testing the relationship between neighborhood structure and delinquency through the use of self-report and victimization data. Confirmation of the theory has been widespread. In this paper we investigate variables mediating between social disorganization and adolescent drug use. We thus extend the research orientation to incorporate drug use and describe a preliminary attempt to examine how neighborhood structure affects behavior. The findings suggest that in the three distinct types of socially disorganized areas that were identified, there was no difference in rates of drug use but that different “mediating factors” appear to be operating in the three different types of communities.     

Actor, situation, and context: A framework for delinquency theory integration

Survey data are presented and discussed as they relate to juvenile involvement in serious and violent delinquency. Juveniles confined in two detention centers were administered self-report questionnaires (n=127). An integrated model that combines social structural variables (i.e., neighborhood disorganization and strain) with social process variables (i.e., parental control, social bond, and delinquent peer associations) was tested by way of path analysis. The data generally support the integrated model, explaining as much as 44% of the variance. Two variables, delinquent peer associations and an overall social bond indicator, directly and significantly predict serious delinquent behavior. Delinquent peer associations are significantly related to neighborhood disorganization, while the social bond is significantly related to parental control and strain. Thus, the data support a systems approach to explaining delinquent behavior, where social structural variables affect social process variables. Earlier versions of this paper were presented at the annul meeting of the Academy of Criminal Justice Sciences, Albuquerque, NM, 1998 and at the annual meeting of the American Society of Criminology, Washington, D.C., 1998.     

Employment,peers, and life-course transitions

One of Sampson and Laub's central findings from their analysis of the Gluecks' data was that reductions in adult criminal behavior were associated with stable employment. In support of their theory of informal social control, they maintained that employment builds social capital that, in turn, bonds young adults to social institutions. Using data from the National Youth Survey we examine the effects of associating with prosocial coworkers on changing delinquent peer networks and on criminal behavior and drug use. The results demonstrate that prosocial coworkers disrupt previously established delinquent peer networks and are associated with reductions in adult criminal behavior.     

An investigation into the empirical relationship between time with peers,friendship, and delinquency

Purpose

Much of the research on peer influence has examined the relationship between peer associations and delinquency. Relatively little empirical research has addressed the effects of delinquent behavior on peer intimacy and time spent with peers. Our research attempts to fill these gaps in the literature as we hypothesize that, net of peer delinquency, delinquents spend more time with their peers but are less closely attached to their peers.

Methods

Using data from two waves of the National Youth Survey (NYS), we present two sets of regression models to account for selection bias resulting from whether respondents reported having friends. To assess the stability of our findings, we supplement our presented findings with extensive use of alternate estimation strategies.

Results

Conclusions regarding our hypotheses do not vary by estimation strategy. Delinquents spend more time with their peers, but delinquents and non-delinquents do not report differences in closeness to their peers.

Conclusions

Given our control variables, our finding introduces complexity in the causal priority between time spent with peers and delinquency. Prior delinquency may be a predictor of more time with peers, but partly as an avenue for opportunities for crime, not for the sake of friendship.     

Behavioral Heterogeneity in Adolescent Friendship Networks

Criminologists’ understanding of peer influences has been greatly advanced by social network methods; however, relatively scant attention has been paid to improving measurement. In particular, research has continued to measure peer influence by averaging the level of delinquency within a peer network, thereby neglecting the role of behavioral heterogeneity. The present study seeks to advance theory and research into peer influences on delinquency by explicitly modeling behavioral heterogeneity in peer networks measured as the variance. Drawing on social learning and opportunity theories, we argue that behavioral heterogeneity should attenuate the effect of average peer delinquency on individual offending. Models using social network data from the Add Health were estimated predicting involvement in two delinquent substance-use acts (cigarette smoking and getting drunk) as a function of peer influences. The results are consistent with our hypothesis, indicating that behavioral heterogeneity matters. Findings suggest that future research employing network models could incorporate peer behavioral heterogeneity to get a more accurate portrait of the processes of peer influence.     

Perceptions of police-juvenile contact predicts self-reported offending in adolescent males

ABSTRACT

Evidence suggests that positive experiences with the police can foster attitudes of respect towards the justice system that can reduce an adolescents’ propensity to commit later illegal behaviors. To advance prior work, we tested whether this association might be stronger for those adolescents who associate with deviant peers. Additionally, we tested whether the link between attitudes towards police and the justice system, and the influence of peer delinquency, would be weaker for those with elevated callous–unemotional (CU) traits. These predictions were examined in a prospective study using a sample (N?=?1,216) of adolescent males who were followed prospectively for 2 years following their first official contact with the juvenile justice system. Positive experiences with the police following the youth’s first arrest were associated with less self-reported delinquency 2 years later, which was partially mediated by reductions in adolescents’ cynicism about the legal system. However, this link was only significant for youth with low levels of peer delinquency. Although CU traits were related to less positive perceptions of experiences with the police and greater cynicism about the justice system, CU traits did not moderate the associations among experiences, attitudes, and later illegal behavior nor did they moderate the influence of peer delinquency.     

Low Self-Control, Deviant Peer Associations, and Juvenile Cyberdeviance

Gottfredson and Hirschi??s (1990) general theory of crime and Akers?? (1998) social learning theory have received strong empirical support for explaining crime in both the physical and cyberworlds. Most of the studies examining cybercrime, however, have only used college samples. In addition, the evidence on the interaction between low self-control and deviant peer associations is mixed. Therefore, this study examined whether low self-control and deviant peer associations explained various forms of cyberdeviance in a youth sample. We also tested whether associating with deviant peers mediated the effect of low self-control on cyberdeviance as well as whether it conditioned the effect. Low self-control and deviant peer associations were found to be related to cyberdeviance in general, as well as piracy, harassment, online pornography, and hacking specifically. Deviant peer associations both mediated and exacerbated the effect of low self-control on general cyberdeviance, though these interactions were not found for the five cyberdeviant types examined.     

ASSESSING AND EXPLAINING MISPERCEPTIONS OF PEER DELINQUENCY*

Peer delinquency is a robust correlate of delinquent and criminal behavior. However, debate continues to surround the proper measurement of peer delinquency. Recent research suggests that some respondents are likely to misrepresent their peers’ involvement in delinquency when asked in survey questionnaires, drawing into question the traditional (i.e., perceptual) measurement of peer delinquency. Research also has shown that direct measures of peer delinquency (e.g., measures obtained via networking methods such as Add Health), as compared with perceptual measures, differentially correlate with key theoretical variables (e.g., respondent delinquency and respondent self‐control), raising the question of whether misperception of peer delinquency is systematic and can be predicted. Almost no research, however, has focused on this issue. This study, therefore, provides detailed information on respondents’ misperceptions of peer behavior and investigates whether individual characteristics, the amount of time spent with peers, and peer network properties predict these misperceptions. Findings indicated that 1) some individuals—to varying degrees—misperceived the delinquent behavior of their peers; 2) self‐control and self‐reported delinquency predicted misperception; 3) respondents occupying densely populated peer networks were less likely to misperceive their peers’ delinquent involvement; and 4) peers who occupy networks in which individuals spend a lot of time together were more likely to misperceive peer delinquency. Implications are discussed.     

Blacks,self-esteem,and delinquency: It's time for a new approach

For decades, sociology and social psychology has debated the nature of self-esteem and its role in determining behavior. More recently, race has been added to the mixture, as social scientists have sought to explain black self-esteem and the involvement of black youth in delinquency. The article reviews a number of studies to explore the relative importance of race as an explanatory factory. Questions of the validity of prior measures of self-esteem are raised, especially where racial comparisons of self-esteem and delinquency were made. This article identifies various conceptual and methodological problems inherent to studies of race, self-esteem, and delinquency. In doing so, distinctions are made among personal and group identity measures of self-esteem in an effort to further the cause of research in this area.     

COMMUNITY STRUCTURE AND ADOLESCENT DELINQUENCY IN ICELAND: A CONTEXTUAL ANALYSIS*

The current study examines the contextual effects of community structural characteristics on adolescent delinquency in Iceland, focusing on how specific individual‐level mechanisms work to mediate the contextual effects. Using multilevel data on 68 school communities and 6,458 adolescents, we find a contextual effect of community social instability (residential mobility, family disruption) on delinquency. Moreover, the findings indicate that specific individual‐level social control mechanisms (Coleman, 1988) explain a part of this effect, namely, embeddedness in community‐based social ties linking parents and adolescents and normlessness. Also, the findings indicate that the individual‐level effect of unsupervised peer activity on delinquency is contingent on embeddedness in social ties as well as on community social instability. The findings have bearing on the cross‐societal generalizability of social disorganization theory.     

GANG HOMICIDE,DELINQUENCY, AND COMMUNITY*

Analysis of community-level data on community areas in Chicago substantiates two conceptual differences: the first. between gang crime and delinquency as community-level phenomena; and the second, between theoretical associations of each of the former to community-area patterns of social disorganization and poverty. One pattern is more common in Chicago's Hispanic communities; the other, in Chicago's black communities. Five measures of the quality of community life used are gang homicide rate, delinquency rate, unemployment rate, percentage living below the poverty level, and mortgage investment per dwelling. Identifying communities as white, black, Hispanic, or mixed and applying discriminant analysis reveal the racial-ethnic communities as distinct social worlds. Regression analyses of gang homicide and delinquency rates show that the two measures display very different patterns of association with other community characteristics. An analysis of the residual change score for gang homicide rate over two time periods indicates the relative stability of community patterns with poverty measures explaining much of the change in patterns. It is concluded that gang homicide rates and delinquency rates are ecologically distinct community problems. The distribution of gang homicide rates conforms to classic theories of social disorganization and poverty, and the distribution of delinquency rates is more generally associated with poverty.     

Similarities and differences between perceptions of peer delinquency,peer self-reported delinquency,and respondent delinquency: An analysis of friendship dyads

Purpose

Despite the peer delinquency measurement debate having profound implications for research, looming questions remain about the validity of various forms of peer delinquency operationalizations. This study examines whether perceptions of peer delinquency form identical latent constructs to both respondent and peer self-reported delinquency.

Methods

Using a dyadic dataset of friendship pairs, confirmatory factor analysis and model comparison tests are used to determine the degree of similarity between perceptions of peer delinquency, respondent self-reported delinquency, and peer self-reported delinquency.

Results

Peer self-reports and respondent perceptions of peer delinquency load on unique constructs across a number of different behaviors. For most behaviors, respondent perceptions of peer delinquency and respondent self-reports load on separate constructs. Results further indicate that respondent and peer self-reported delinquency are separate latent constructs. Finally, the strength of the association between respondent and peer delinquency is substantively smaller in magnitude, by as much as a factor of three in some instances, when peer delinquency is measured via peer self-reports in place of respondent perceptions.

Conclusions

Reports of peer delinquency provided directly from peers demonstrate strong discriminant validity in relation to self-reported delinquency, while perceptions of peer delinquency demonstrate poorer discriminant validity, particularly for theft and violence constructs.     

Reconsidering Peer Influences on Delinquency: Do Less Proximate Contacts Matter?

Much research on adolescent delinquency pivots on the notion of peer influence. The peer effect that is typically employed emphasizes the transmission of behaviors and attitudes between adolescents who are directly linked. In this paper, we argue that to rely solely on those direct social ties to capture peer influence oversimplifies the realities of adolescent society. We use data from the National Longitudinal Study of Adolescent Health to show that indirect peer relations can exercise independent influences on adolescent delinquency. Adolescents actively draw on the examples of friends of friends, and even more distal peers, as they develop their repertoires of action and identity. We argue, however, that this behavior actually reflects adolescents’ ongoing struggle to impress their closest friends and to preserve their social circle. Indeed, the extent to which adolescents are willing to model the behavior of indirect contacts seems to decline as that behavior becomes more dissimilar from that of their close friends. Our findings dovetail with an account of the adolescent as a rational actor who struggles for social acceptance in a complex peer environment which offers conflicting behavioral models.

Self-control, Victimization, and their Influence on Risky Lifestyles: A Longitudinal Analysis Using Panel Data

This research expands past investigations into the influence of low self-control as a risk factor for criminal victimization. Specifically, we consider two questions: (1) whether low self-control at one point in time can predict future victimization, and (2) whether victims alter lifestyle choices (like their own delinquency and contact with delinquent peers) in response to their earlier victimization. We answered these questions using three waves of adolescent panel data from the evaluation of the Gang Resistance Education and Training program. Our results support the predictions of self-control theory, showing that low self-control measured at an earlier time is associated with later victimization, even after controlling for past victimization, delinquency, social bonds, and delinquent peer contact. Likewise, self-control appears to influence the relationship between earlier victimization and later lifestyles.

Generalizing general strain theory: An examination of an offending population

We attempt to investigate the generality of general strain theory (GST) by exploring the operation of general strain in an offending population. Data are obtained from self-report interviews of approximately 150 youths who had been adjudicated for a variety of offenses; all had been identified as chemically abusing or dependent. Using measures of strain and negative affect, as well as strain-exacerbating factors such as peer delinquency and strain-alleviating factors such as family communication and cognitive, social, physical, emotional, and spiritual coping skills, we find support for some of the basic tenets of GST. Implications of the findings for future research are discussed.     

Sex as a moderator and perceived peer pressure as a mediator of the externalizing-delinquency relationship: A test of gendered pathways theory

Purpose

The current study sought to determine whether sex moderated peer mediation of the externalizing-delinquency relationship as part of a larger test of the gendered pathways theory of crime.

Methods

Data gathered from 4,144 (2,079 males and 2,065 females) members of the National Longitudinal Survey of Youth-Child sample were subjected to simple correlational and moderated mediation analysis.

Results

Externalizing behavior and delinquency correlated equally in boys and girls but in testing a full moderated mediation model it was discovered that sex moderated the mediating effect of perceived peer pressure on the externalizing–delinquency relationship. Whereas externalizing behavior predicted delinquency in both boys and girls, perceived peer pressure only mediated the externalizing-delinquency relationship in boys.

Conclusions

These results support the gendered pathways to delinquency model to the extent that the relationship between childhood externalizing behavior and delinquency was mediated by perceived peer pressure in males but not females. The implications of these results for theoretical refinement of the gendered pathways approach and crime prevention and intervention are discussed.     

Gender Differences in Delinquency and Situational Action Theory: A Partial Test

This paper investigates to what extent a recent perspective in criminology, Situational Action Theory, is valid for both males and females and to what extent elements from the theory explain gender differences in delinquency. Data are used from the first (N?=?843) and second (N?=?616) wave of the Study of Peers, Activities, and Neighborhoods, which included detailed data about core elements of Situational Action Theory (morality, self-control, unsupervised peer activity and peer deviancy), proposed indirect causes (bonds with parents and school, parental monitoring) and self-reported delinquency. Cross-sectional and lagged Tobit regression analyses show that the core relations with delinquency are not significantly different between boys and girls and that the elements of Situational Action Theory are able to explain gender differences in delinquency for a substantial part. However, there is still a remaining independent effect of gender on current and lagged delinquency.     

Rethinking the IQ-delinquency relationship: A longitudinal analysis of multiple theoretical models

Criminological research has consistently demonstrated a relationship between IQ and delinquency, yet scholars continue to debate the precise mechanisms by which IQ should have an effect on delinquent behavior. Although researchers typically view the IQ-delinquency relationship as a function of “school performance,” additional explanations exist that have yet to be formally tested in conjunction with one another within the same analysis. Using data from the National Longitudinal Survey of Youth (NLSY) we extend existing research by assessing the indirect effect of IQ on delinquency through three intervening processes: school performance, deviant peer pressure, and self-control. The results indicate strong support for the school performance model (especially when linked with self-control), yet considerable evidence exists of an indirect effect of IQ on delinquency through both deviant peer pressure and self-control. The implications for future theoretical development and integration are discussed.     

UNSTRUCTURED SOCIALIZING AND RATES OF DELINQUENCY

This article applies an individual-level routine activities perspective to explaining rates of delinquency. The theoretical analysis also links the opportunity processes of that perspective to key themes of social disorganization theory. Multilevel analyses of 4, 358 eighth-grade students from thirty-six schools in ten cities support the central hypothesis: Time spent in unstructured socializing with peers has both individual and contextual effects that explain a large share of the variation in rates of delinquency across groups of adolescents who attend different schools. In addition, parental monitoring has a very strong contextual effect on unstructured socializing, which supports the proposed integration of routine activity and social disorganization perspectives.
