PEER SIMILARITY IN DELINQUENCY FOR DIFFERENT TYPES OF FRIENDS: A COMPARISON USING TWO MEASUREMENT METHODS*

Peer similarity in delinquency has been studied extensively. But basic questions remain about measuring peer delinquency and how important the nature of relationships with delinquent peers is. This article uses data from the NSCR School Project, which has collected unusually detailed information about delinquent peers and the social networks of adolescents. We examine differences in the roles of regular friends and best friends with regard to peer similarity in delinquent behavior. We also contrast two methods of measuring peer delinquency: the conventional one of asking respondents about their peers, and the social network method, by which peers report about themselves. The results show that respondents can have best and regular friends who differ in their degree of delinquency, and that the association between respondent and peer delinquency does not differ much between friends and best friends. At the same time, our results suggest that both types of peers influence the level of respondent delinquency. Measures based on the direct network method resulted in higher estimates of peer delinquency, but in lower estimates of the association between respondent and peer delinquency.     

Community-level influences on individuals' social bonds,peer associations,and delinquency: A multilevel analysis

Social disorganization theory is usually considered a macro-level theory, and therefore has been used almost exclusively to explain variation in crime rates. Shaw and McKay, however, also applied their theory to explaining micro-level variation in social bonds, peer associations, and delinquency. Specifically, they argued that social bonds and peer associations actually mediated the influence of social disorganization on delinquency. Little empirical research has focused on this interpretation of their theory. In this study the connections between neighborhood-level social disorganization and individual-level social bonds, peer associations, and delinquency are explicated and tested empirically with multilevel data and hierarchical linear modeling. The results show that social disorganization significantly affects peer associations but not social bonds. In addition, the effect of social disorganization on delinquency is mediated fully by peer associations. Implications for future research on social disorganization theory are discussed.     

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.

DELINQUENT PEERS IN CONTEXT: A LONGITUDINAL NETWORK ANALYSIS OF SELECTION AND INFLUENCE EFFECTS*

In this article, longitudinal social network data are analyzed to get a better understanding of the interplay between delinquent peers and delinquent behavior. These data contain detailed information about the social networks of secondary school students from the same grade, their delinquent behavior, and many relevant correlates of network formation and delinquency. To distinguish selection and influence processes, a method (Simulation Investigation for Empirical Network Analyses, SIENA) is used in which network formation and changes in delinquency are simulated simultaneously within the context of other network processes and correlates of delinquency. The data and the method used make it possible to investigate an unusually wide array of effects on peer selection and delinquent behavior. The results indicate that similarity in delinquency has no significant effect on the selection of school friends when other network dynamics are taken into account. However, the average delinquency level of someone's friends in the school network does have a significant, although relatively small, effect on delinquent behavior of the respondents, beyond significant effects of changes in the level of self‐control and morality. Another peer‐related change, leaving or joining informal street‐oriented youth groups, also appears to have a substantial effect on changes in delinquency.     

Peer pressure and adolescent substance use

Peer influence is regarded as one of the strongest determinants of juvenile delinquency and particularly adolescent substance use. A commonly held view is that social pressure from friends to use drugs and alcohol is a major contributor to substance use. Yet the notion of peer pressure, implied by the association between peer-group associations and drug behavior, is seldom tested empirically. As a crucial test of the group pressure model, this research examines the role of peer pressure in mediating the effect of differential association on individual use. Moreover, few studies examine the nature of the relationship between peers and substance use as it relates to the processes leading toand from use. Drawing on differential association and social learning theories, our research specifies the social processes (socialization, group pressure, social selection, and rationalization) which dictate particular causal pathways leading to and from substance use and then estimates the reciprocal influences among differential association, social pressure from peers, attitudes favorable toward substance use, and individual use. Using the 1977–1979 National Youth Survey panel data, we estimate a covariance structural equation model allowing for correlated measurement error. In the cross-sectional analyses, we find no main effects of overt peer pressure on substance use. Estimation of the reciprocal effects model also reveals that overt peer pressure does not significantly influence substance use and does not mediate the effect of differential association. Instead, the influences of socialization, social selection, and rationalization play significant roles in understanding substance use.An earlier version of this paper was presented at the 1994 American Society of Criminology meetings in Miami, Florida.     

SIBLING EFFECTS ON SUBSTANCE USE AND DELINQUENCY*

Sibling effects refer to the immediate influence one sibling may have on another or to indirect influences through their embeddedness in a common friendship network We used three aspects of sibling mutual interaction—warmth, conflict, and frequency of contact with mutual friends—to evaluate sibling effects on delinquency and substance use in 135 brother pairs, 142 sister pairs, and 141 mixed-sex pairs in the Arizona Sibling Study (primarily aged 10–16 years). We hypothesized that sibling relationship variables would condition the behavioral resemblance of the younger and older sibling. For both substance use and delinquency, this prediction was confirmed for warmth and mutual friends: Sibling pairs who reported warmer mutual relationships or greater contact with mutual friends were more alike behaviorally. The statistical sibling effects were not explained by social class, parental substance use, or rearing styles. We interpret them as the influence of one sibling on the other and as the influence arising from sharing common friends. Given the existence of sibling effects, the strength of shared familial influences of other origins must be revised downward.     

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.     

TESTING MOFFITT'S ACCOUNT OF ADOLESCENCE‐LIMITED DELINQUENCY*

Much of the research testing Moffitt's taxonomy of antisocial behavior has concentrated on life‐course‐persistent as opposed to adolescence‐limited offending. For Moffitt, adolescence‐limited delinquency occurs near puberty as a function of factors endemic to the peer social context of adolescence, including the realization that adolescents are physically mature enough to engage in adult‐like behaviors, but are forbidden to engage in such acts because of their biological age. Using data from the Youth‐In‐Transition survey, we find that adolescence‐limited delinquency is characterized by involvement in rebellious but not aggressive delinquency. Further, rebellious delinquency is accounted for by the interaction between early maturity and the autonomy aspects of peer activities.     

The Influence of Dating Relationships on Friendship Networks,Identity Development,and Delinquency

Prior research has documented general associations between dating and delinquency, but little is known about the specific ways in which heterosexual experiences influence levels of delinquency involvement and substance use. In the current study, we hypothesize that an adolescent's level of effort and involvement in heterosexual relationships play a significant role in forming the types of friendship networks and views of self that influence the likelihood of delinquency involvement and substance use. Analyses based on a longitudinal sample of adolescent youth (n = 1,090) show that high levels of dating effort and involvement with multiple partners significantly increases unstructured and delinquent peer contacts, and influences self‐views as troublemaker. These broader peer contexts and related self‐views, in turn, mediate the path between dating relationships, self‐reported delinquency, and substance use. Findings also document moderation effects: among those youths who have developed a troublemaker identity and who associate with delinquent peers, dating heightens the risk for delinquent involvement. In contrast, among those individuals who have largely rejected the troublemaker identity and who do not associate with delinquent friends, dating relationships may confer a neutral or even protective benefit. The analyses further explore the role of gender and the delinquency of the romantic partner.     

How Do They ‘End Up Together’? A Social Network Analysis of Self-Control,Homophily, and Adolescent Relationships

Self-control theory (Gottfredson and Hirschi 1990) argues that individuals with similar attributes tend to ‘end up together’ (i.e., homophily) because of the tendency to select friends based on self-control. Studies documenting homophily in peer groups interpret the correlation between self-control, peer delinquency, and self-reported delinquency as evidence that self-control is an influential factor in friendship formation. However, past studies are limited because they do not directly test the hypothesis that self-control influences friendship selection, nor do they account for other mechanisms that may influence decisions. As a result, it is unclear whether the correlation between individual and peer behavior is the result of selection based on self-control or alternative mechanisms. To address this gap in the literature this study employs exponential random graph modeling to test hypotheses derived from self-control theory using approximately 63,000 respondents from 59 schools from the National Longitudinal Survey of Adolescent Health (Add Health). In contrast to the predictions made by Gottfredson and Hirschi (1990), and the conclusions drawn from prior research, there is little evidence that self-control influences friendship selection. The findings are embedded in past work on the relationship between self-control and peer relationships, and implications for future research are discussed.     

ADOLESCENT ROMANTIC RELATIONSHIPS AND DELINQUENCY INVOLVEMENT

While much attention has centered on the role of peer influence for adolescent delinquency, that of romantic partners has been largely neglected. Recent analyses of romantic relationships during the adolescent period suggest their general importance to development; research highlights that adolescents themselves frequently describe these relations as relatively intimate and influential. Thus, while classic theoretical frameworks such as differential association theory have often centered on the role of peers, their general logic is consistent with the notion that such relationships may indeed "matter" as a source of influence on delinquent behavior. Data from the National Longitudinal Study of Adolescent Health are well suited for examining the role of romantic partners because they allow for the identification and recreation of friendship networks and connections between romantic partners. Forging these interconnections, we link friends' and romantic partners' delinquency to respondents' own delinquency, enabling an examination of romantic partner influence on adolescent delinquency, beyond that influence associated with friends' behaviors. Drawing on theories of gender stratification, we also explore whether the effect of romantic partners' behavior is conditioned by gender. Findings reveal that romantic partners' delinquency exerts a unique effect on respondents' delinquency net of friends' delinquency and control variables. Additionally, romantic partners' deviance has a stronger effect on female involvement in minor deviance. We find no evidence, however, that gender conditions the strength of romantic partners' more serious delinquency on respondents' serious delinquency.     

The First Delinquent Peers Are the Most Important: Examining Nonlinearity in the Peer Effect

Criminologists have long recognized the importance of peers in the etiology of delinquency. Yet, the bulk of empirical studies on this topic make the implicit assumption that the peer effect to be conditioned is linear. With few notable exceptions, prior criminological research has not thought deeply about possible nonlinearity in the peer effect. To address this issue, the present study examines whether the functional form of the relationship between peer and respondent smoking, getting drunk, and fighting is nonlinear, and whether this nonlinearity is moderated by lagged respondent delinquency. Logistic regression models on adolescents from The National Longitudinal Study of Adolescent Health indicate that the marginal effect of peer delinquency on respondent delinquency decreases as the count of delinquent friends increases, consistent with a satiation effect. Moreover, the models indicate that the nonlinear effect of peer delinquency on respondent delinquency is moderated by prior respondent delinquency.     

Acculturation,Social Context,and Drug Use: Findings from a Sample of Hispanic Adolescents

Criminologists have largely neglected the influence of acculturation in the etiology of Hispanic drug use and delinquency. This is somewhat surprising since a long line of research from several disciplines has consistently linked higher levels of acculturation to greater incidence of negative social, health, and behavioral outcomes. A major shortcoming of this extant literature, however, is its failure to consider the acculturation-drug use link within a particular explanatory framework. This study attempts to address this oversight by examining the acculturation-drug use relationship within the context of gang membership, drug availability, and susceptibility to peer influence. Using data from a sample of Mexican–American adolescents residing in the American Southwest, a series of regression equations were estimated exploring the relative effects of acculturation, gang membership, drug availability, and susceptibility to peer influence on drug use. Separate analyses were conducted on minor (e.g., alcohol, marijuana) and major (e.g., cocaine, heroin) drug use. Findings indicated that all study variables, except acculturation, were significantly related to drug use.     

A Sensitivity Analysis of Egocentric Measures of Peer Delinquency to Latent Homophily: A Research Note

Objectives

Egocentric measures of peer delinquency, obtained through a census of a social network, have become the preferred operationalization for examining the relationships between social influence and delinquency. Studies regressing ego’s delinquency on the delinquency of nominated friend/s (i.e. alter/s) conclude that a statistically significant coefficient provides evidence of social influence. However, the inferences drawn from these studies may be biased by the introduction of artificial statistical dependence as a consequence of using social network data in a regression framework. Recent work (Shalizi and Thomas Sociol Methods Res 40:211–239, 2011) shows that latent homophily, or unmeasured confounding of observables, may lead to nonzero estimates of social influence, even if there is no causal significance. To examine this possibility, sensitivity analyses have been created (e.g. VanderWeele and Arah Epidemiology 22:42–52, 2011; VanderWeele Sociol Methods Res 40:240–255, 2011) to determine the robustness of an estimated coefficient to latent homophily.

Methods

In this research note, I examine the robustness of estimates for social influence from two articles (Haynie Am J Sociol 106:1013–1057, 2001; Meldrum et al. J Res Crime Delinq 46:353–376, 2009) using egocentric measures of peer delinquency.

Results

Findings indicate that for large, precise point estimates, highly improbable conditions are needed to explain away the effects of social influence. However, less precise point estimates (i.e. large standard errors) are more sensitive to latent homophily.

Conclusions

The analyses indicate that studies using egocentric measures should conduct sensitivity tests, particularly when the estimated effect is weak and/or has a relatively large standard error. Scripts written in the free programming language R (R Core Team R: a language and environment for statistical computing. R Foundation for Statistical Computing, Vienna, 2012) are provided for researchers to conduct such analyses.     

Social Correlates of Delinquency for Youth in Need of Mental Health Services: Examining the Scope Conditions of Criminological Theories

While both traditional criminological inquiry and mental health research have identified internal and external constellations of risk factors associated with juvenile offending, interdisciplinary discourse has been limited. This paper takes a step in bridging the gap between criminological literature and work in the field of children’s mental health by evaluating the combined effects of social and mental health predictors on juvenile delinquency in a sample of youth with diagnosed clinical disorders. Results of multivariate analyses indicate that both traditional social risk factors as well as indicators of the nature and severity of youths’ mental health disorders contribute to delinquency. Moreover, the influence of one well-established risk factor, self-control, on delinquency is moderated by the presence of oppositional defiant disorder. The results of this study suggest that researchers and practitioners should consider the cumulative influence of social risk factors and psychological impairment in the etiology of delinquency.     

A TEST OF LIFE‐COURSE EXPLANATIONS FOR STABILITY AND CHANGE IN ANTISOCIAL BEHAVIOR FROM ADOLESCENCE TO YOUNG ADULTHOOD*

Using longitudinal data from a sample of 236 young adults and their romantic partners, we tested a life‐course model that integrates social control and peer influence arguments with the idea of assortative mating. For both males and females, adolescent delinquency and affiliation with deviant peers predicted having an antisocial romantic partner as a young adult. Involvement with an antisocial romantic partner, in turn, had both a direct effect on crime as well as indirect influence through adult peer affiliations. For females, quality of the romantic relationship also predicted crime. The analyses revealed several moderating influences in addition to these mediating effects. For females, a conventional romantic partner, strong job attachment, and conventional adult friends all served to moderate the chances that a woman with a delinquent history would graduate to adult crime. In contrast, only conventional adult friends served this function for males.     

Does the measurement of peer deviance change the relationship between self-control and deviant behavior? An analysis of friendship pairs

Purpose

The measurement debate between social learning and self-control theories has predominantly focused on self-control, leaving an unexplored and equally important measurement controversy concerning the operationalization of the peer delinquency construct. This study addresses how self-control's relationship with deviant and criminal behavior changes when peer deviance is statistically controlled for using an indirect, perceptual measure or a self-report directly from a peer.

Methods

Data from 796 friendship pairs are used to estimate a series of regression models that regress respondent deviance onto indirect and direct peer deviance and attitudinal and behavioral self-control measures while controlling for elements of the social bond and demographic characteristics.

Results

When an indirect measure of peer delinquency is replaced with a direct measure from respondents’ friends, the relationships between self-control - attitudinal and behavioral measures - and deviance and criminal behavior are consistently larger. The use of a direct peer deviance measure does not prove the peer deviance-crime relationship spurious, but does substantially weaken the relationship between self-control and deviance and criminal behavior.

Conclusions

The strength of the relationship between self-control and deviant/criminal behavior is contingent on how peer deviance is operationalized, regardless of how self-control is measured (attitudinally or behaviorally).     

DELINQUENCY BALANCE: REVISITING PEER INFLUENCE*

An impressive number of inquiries across an array of methodological specifications has demonstrated that deviant peers are an important correlate of various criminological outcomes, which include within‐ individual change and stability in offending behavior. Still, the causal mechanisms of peer influence arguably remain underdeveloped (Giordano, 2003; Warr, 2002). In an attempt to expand the dialogue on the nature of peer influence, this inquiry proposes that scholars would benefit from considering relative peer deviance in addition to exposure to deviant peers. Specifically, it argues that an imbalance in delinquency between friends helps to explain delinquency change/stability; therefore, exposure to deviant peers is not always risky and exposure to less deviant peers is not always protective. The analysis uses the Add Health data to construct within‐individual and across‐individual (delinquency) difference scores and relies on self‐reports rather than on perceptions for the best friends' delinquency. The results provide support for the premise that adolescents attempt to achieve delinquency “balance” with their best friend by changing behavior, net of raw peer deviance levels (i.e., objective exposure). The findings also suggest that balance is not achieved through selection, given that the deviance gap between the respondent and his or her best friend does not predict friendship stability. The discussion considers these results from a theoretical and empirical perspective and offers several avenues for future research.     

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.     

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.
