Differentiating Peer Contexts and Risk for Adolescent Substance Use

The peer context is perhaps the most salient, robust predictor of an adolescent's substance use. However, in previous studies, the peer context is often poorly defined. The current study examined 3 models to understand how substance use within best friendships, peer cliques, and social crowds predicts adolescents' substance involvement. A sample of 377 high school juniors and seniors completed surveys assessing substance use and peer relationships. Results suggest that each of these 3 dimensions of the peer context uniquely predict adolescent substance use. Moreover, these peer contexts interacted in the prediction of adolescents' substance use such that adolescents who were more highly embedded in substance-using peer contexts showed greater risk for substance use whereas adolescents with substance-using best friends showed a reduced risk for substance use if they had other close friends who were less involved with substances.     

Procedural Justice in Family Conflict Resolution and Deviant Peer Group Involvement Among Adolescents: The Mediating Influence of Peer Conflict

The involvement of adolescents with deviant peer groups is one of the strongest proximal correlates to juvenile delinquency and stems from a variety of causes. Past research has linked ineffective parenting with peer variables, including deviant peer group involvement and peer conflict during adolescence. In this study, adolescents’ appraisals of procedural justice within the family (adolescents’ appraisals of how fairly they are treated by parents in the process of resolving family conflict) were examined as one aspect of effective parenting that may relate to deviant peer group involvement in early adolescence. Data from 1660 middle school students (ages 11–14, mean = 12.6) indicated that higher appraisals by adolescents of procedural justice during family conflict resolution were related to lower levels of both peer conflict and deviant peer group involvement. A structural model was tested in which the relationship between adolescents’ appraisals of procedural justice in the family and deviant peer group involvement was partially mediated by measures of peer conflict. This model was found to have adequate fit to the data, indicating that part of the relationship between procedural justice appraisals and deviant peer group involvement can be explained by levels of peer conflict. Implications of these findings are discussed.

When Formal Sanctions Encourage Violent Offending: How Violent Peers and Violent Codes Undermine Deterrence

Research focusing on deterrence has stressed the negative relationship between perceived formal sanctions and criminal behavior, ignoring the possibility that in some populations formal sanctions may serve to increase offending under some conditions. Utilizing a sample of 300 homeless street youths, the study explores if violent peers, violent values, and the culture of the street moderates the association between perceived legal sanctions and violent offending. The results suggest that violent peers, violent values, and the culture of the street condition the perceived certainty of punishment so that it leads to higher levels of violence. Further, the culture of the street conditions the relationship between perceived severity of punishment and violence. Theoretical and policy implications are discussed.     

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.     

Rap Music Genres and Deviant Behaviors in French-Canadian Adolescents

This study investigated the links between the preference for 4 rap music genres (American rap, French rap, hip hop/soul, and gangsta/hardcore rap) and 5 types of deviant behaviors in adolescence (violence, theft, street gangs, mild drug use, and hard drug use). The effects of peers' deviancy, violent media, and importance given to lyrics were statistically controlled. A self-report questionnaire was distributed to a sample of 348 bilingual French-Canadian adolescents (age: M = 15.32; SD = 0.9; 185 girls and 163 boys). Results indicated that rap music as a whole was linked to deviant behaviors, however the nature of the relation differed according to genres. Preference for French rap had the strongest links to deviant behaviors, whereas preference for hip hop/soul was linked to less deviant behaviors. Results are discussed within the psychosocial and sociocognitive perspectives on music influence in adolescence and also within the perspective of normative deviant behaviors in adolescence.     

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.     

Design and Implementation of Parent Programs for a Community-Wide Adolescent Alcohol Use Prevention Program

SUMMARY

Project Northland is a comprehensive community trial designed to evaluate programs for the primary prevention of alcohol-related problems during adolescence. It uses a community-wide model, that includes both demand and supply reduction techniques. The first phase of Project Northland (grades 6-8) was completed with the effective implementation of multiple, complementary programs including a multi-year social behavioral curriculum, intensive parental involvement components, peer leadership opportunities, and community-level changes through the formation of local task forces. This article describes the process used for developing and implementing the comprehensive parent interventions used during the first phase of the research, highlighting the elements that led to the successful implementation of the programs with very high participation rates by parents, their young adolescents, teachers, and community members.     

Similarity between deviant peers: Developmental trends in influence and selection*

The association between an adolescent's own behavior and that of his or her peers remains a key empirical finding in the study of delinquency, and this similarity is often explained in criminology by invoking processes of social influence and homophily. Adolescence is a period of rapid change for both individuals and their surroundings, however, and influence and homophily are often discussed without attending to their development over time. In the current study, I employ longitudinal social network models to estimate social influence and homophily related to alcohol and cigarette use and to determine whether there is change in the strength of these processes. Furthermore, I test whether the broader social environment conditions these processes and their observed changes. The results from this study indicate that although influence from peers decreases from early to mid-adolescence, homophily on drinking and smoking increases. There is also evidence that school-level opportunities and expectations affect social influence and homophily but do not account for the average changes observed in these processes.     

After-School Programs as a Prosocial Setting for Bonding Between Peers

This study reports on the longitudinal analysis of a structured after-school arts program for Canadian youth, ages 9 to 15 years, from low-income communities where the relationship of peer social support, family interactions, and psychosocial outcomes is evaluated. Multi-level growth curve analyses suggest an increase in prosocial development with peer social support and a decrease in prosocial development when negative family interactions are present. Comparisons between matched controls, using estimated linear propensity scores, revealed significant improvement in prosocial behaviors for the intervention group. The structured after-school arts program was found to increase prosocial behaviors and bonding with peers for youth from low-income communities.
