Social Learning,Social Disorganization,and Psychological Risk Factors for Criminal Gangs in a British Youth Context

ABSTRACT

Using longitudinal data from a British longitudinal cohort study (ALSPAC), the current study examines “developmental domains” from individual, peer, and community risk factors. Using four logistic regression models, we looked at 10 correlations between children’s experience with risk factors outlined by the literature and criminal gang association. Gang membership was associated with drug use, delinquent peers, and disorganized neighborhoods. Further, early diagnoses of childhood aggression, ADHD, depression, and Oppositional Defiant Disorder, were not associated with later, adolescent youth gang membership. Our results suggest community based programs that stem from social learning policies and collective efficacy militate against gang growth.     

Situational Peer effects on Adolescents’ Alcohol Consumption: The Moderating Role of Supervision,Activity Structure,and Personal Moral Rules

Using five waves of unique space-time budget data, this study investigates the relevance of peer presence and behavior on adolescents’ alcohol consumption at a situational level, addressing to which degree these situational peer effects are moderated by the setting and by individual differences. Multilevel models, predicting the probability of alcohol consumption in a given hour, show that peers’ alcohol misuse is most relevant during unstructured activities while unsupervised. However, individuals differ in their susceptibility to these situational processes, with adolescents holding strong moral convictions against alcohol consumption being basically immune to situational peer effects, even during unstructured and unsupervised activities.     

Effects of parenting,father absence,and affiliation with delinquent peers on delinquent behavior among African-American male adolescents

This study examined the effects of different aspects of parenting, father absence, and affiliation with delinquent peers on delinquent behavior in a cohort of African-American male adolescents. One round of survey data was collected from the youths' mothers or mother surrogates (N = 175) and two rounds of survey data were collected from the adolescents themselves. Analyses revealed that mothers' perceived control of sons' behavior was a deterrent of delinquent behavior, while other aspects of parenting (e.g., mother-son communication and relations) were not. The effect of mothers' perceived control was not mediated by adolescents' affiliation with delinquent peers. The effects of mothers' parenting variables and peer affiliation did not vary significantly by family structure, but socioeconomic disadvantage was more strongly associated with delinquent behavior in father-absent families. Though parenting effects were modest, this study suggests that African-American male adolescents are less likely to engage in delinquent behavior if they are closely monitored and supervised by their parents.     

Temperament Alters Susceptibility to Negative Peer Influence in Early Adolescence

The role of deviant peers in adolescent antisocial behavior has been well documented, but less is known about individual differences in susceptibility to negative peer influence. This study examined whether specific temperament dimensions moderate the prospective relationship between peer deviance and delinquent behavior in early adolescence. Participants included 704 adolescents recruited from the community. At baseline, parents provided information on adolescents’ temperament and youth reported on their own and their friends’ delinquent behavior. Self-reports of adolescents’ delinquent behavior were collected again 16 months later. Peer deviance was related to delinquent behavior over time more strongly for adolescents with low levels of task orientation, flexibility, and positive mood, compared to youth with high levels of task orientation, flexibility, and positive mood. Analyses of gender differences indicated that low flexibility increased susceptibility to negative peer influence only for males, but not females. General activity level and sleep rhythmicity did not moderate the effect of peer behavior on delinquency.     

Social Support,Loyalty to Delinquent Peers,and Offending: An Elaboration and Test of the Differential Social Support Hypothesis

While most research focuses on the positive effects of social support on adolescent development, Cullen hypothesizes that social support may promote crime and delinquency under certain conditions. Specifically, when social support is derived from deviant sources, it may promote offending behavior. In this study, we test an elaborated version of this “differential social support” hypothesis. The results indicate that, among adolescents who associate with delinquent peers, peer social support is associated with an increase in delinquent behavior. These findings highlight the potential “dark side” of social support. Implications for criminological theory and crime control policy are discussed.     

Correlates of aggressive and delinquent conduct problems in adolescence

The primary purpose of the study was to test a hypothetical model for aggressive and delinquent conduct problems in adolescence. A total of 168 adolescents from 121 families were studied using several questionnaires and a semi‐structured interview. The following factors were considered: obstetric complications, temperament (novelty‐seeking), self‐esteem, family influences (perceived parenting, alcohol abuse/dependence of parents, antisocial personality disorder of the father) and peer‐group characteristics (peer rejection and membership in a deviant peer group). The evaluation methods applied included correlation analyses and testing of two hypothetical models using structural equation modeling. The correlation analyses revealed significant relationships between adolescent aggressive and delinquent behavioral problems and parental antisocial behavior; perceived parental rejection and low emotional warmth; adolescent novelty‐seeking, self‐esteem, peer rejection and peer deviance. The two empirical models, separately for aggressive and delinquent behavior problems, revealed direct relationships between paternal antisocial behavior, parental rejection, adolescent novelty seeking, peer deviance, peer rejection, and offspring aggression and delinquency. There were, however, two differences with respect to the relationships between peer rejection, peer deviance, aggression and delinquency. First, peer rejection was more strongly associated with aggressive behavior and only moderately linked to delinquency. Second, deviance in the peer‐group was found to be closely related with delinquency but only moderately with aggression. Our findings suggest that several pathways for aggressive and delinquent conduct problems are comparable while others were not. Regarding the findings of the empirical models, we conclude that only intervention measures that include parents, peers and individual adolescents may help decrease the incidence of aggressive and delinquent conduct problems.

Association with Delinquent Peers: Intervention Effects for Youth in the Juvenile Justice System

Although association with delinquent peers is a recognized precursor to ongoing delinquency problems, youth in the juvenile justice system are commonly prescribed intervention services that aggregate delinquent youth. However, little is known about the process variables that mediate the relationship between aggregating youth in intervention settings and poor subsequent outcomes. We examined data from two randomized intervention trials (one male sample and one female sample) with delinquent adolescents placed either in Multidimensional Treatment Foster Care (MTFC) or in group care. Path analyses suggested that the MTFC youth had fewer associations with delinquent peers at 12 months than did the group care youth. Further, associating with delinquent peers during the course of the intervention mediated the relationship between group condition and 12-month delinquent peer association. Implications for the development of interventions with delinquent youth are discussed.     

Self-Control and Risky Lifestyles in Context: Cross-Level Integration between Opportunity and Collective Efficacy in the Study of Peer Victimization among South Korean Youth

The study applies individual trait and opportunity perspectives at the individual-level factors associated with peer victimization among South Korean youth. The theoretical analysis integrates individual-level perspectives with community-level perspective. Data are derived from the Korean Youth Panel Survey, which provided information for a sample of 2844 adolescents, aged 11. Findings revealed significant effects of low self-control and risky lifestyles (delinquent peer associations and juvenile delinquency) on peer victimization. The results lend support for the application of self-control theory as well as lifestyles and routine activities theory to understand peer victimization of adolescents in South Korea. However, there was no independent effect of neighborhood collective efficacy on peer victimization, nor did neighborhood collective efficacy attenuate or condition the individual-level effects on peer victimization.     

CLASSWIDE PEER TUTORING: AN INTEGRATION STRATEGY TO IMPROVE READING SKILLS AND PROMOTE PEER INTERACTIONS AMONG STUDENTS WITH AUTISM AND GENERAL EDUCATION PEERS

A multiple baseline design across subjects with a reversal was used to examine the effects of classwide peer tutoring relative to traditional reading instruction on reading skills and social interaction time for 3 high-functioning students with autism and their typical peers in integrated, general education classrooms. Traditional reading instruction consisted largely of teacher-led instruction with individual student participation and seat work. Classwide peer tutoring consisted of 25 to 30 min of well-specified instruction in which tutor—learner pairs worked together on a classwide basis on reading fluency and comprehension skills. All students participated in 15- to 20-min unstructured free-time activities immediately following reading instruction. Results of reading assessments demonstrated that classwide peer tutoring increased reading fluency and correct responses to reading comprehension questions for students with autism and their peers. The procedure further increased the total duration of free-time social interactions for students with autism and typical peers, with individual variation in performance.     

Gender Differences in Associations with Deviant Peer Groups: Examining Individual,Interactional, and Compositional Factors

Researchers have long known that boys are more likely to have deviant peers than are girls. Yet, little research has tried to explain why boys and girls differ in their decision to associate with deviant peers. With the salience of deviant peers well established as a robust predictor of delinquency, we address the question, are the predictors of association with deviant peers different for boys and girls? In our examination of family and community processes, individual effects, and peer group composition factors, we find that the predictors of association with deviant peers differ by gender. In addition, our findings suggest gender divergences in the causes of both deviant peer association and deviant peer pressure. We discuss the implications of our research for both theoretical development and appropriate model estimation.     

Acculturation, peer relations, and delinquent behavior of Chinese-Canadian youth

Studies have reported that youth of Chinese descent in North America tend to have lower rates of delinquency. Some investigators have attributed this phenomenon to the restraining effects of Chinese culture. In this study, acculturation, peer relations, and delinquency were examined in a sample of Chinese-Canadian youth. The results revealed that adherence to Chinese culture was related to lower delinquency, whereas the opposite was true for North American acculturation. It was found that association with delinquent peers was positively related and attachment to peers negatively related to delinquency, as predicted by differential association and control theories, respectively. Moreover, acculturation was positively related to association with delinquent peers and attachment to peers. However, there was the unexpected finding that association with Chinese peers was positively related to delinquency. These seemingly contradictory findings demonstrate the dilemma experienced by Chinese youth in North America.     

Designing road safety interventions for young drivers – The power of peer influence

Peer passengers are associated with risky driving behaviour and increased collision rate in young drivers, but the mechanism by which young drivers are influenced by their peers is not well understood. Here we report two studies that explore the effect of peer influence on young drivers. The first explored the relationship between susceptibility to peer influence and young drivers’ engagement in risky driving behaviour. 163 young drivers completed self-report measures of risky driving behaviour and susceptibility to different forms of peer influence. Results showed that young drivers who were influenced by their peers to attain social prestige and through peers intervening in their decisions committed more driving violations. The second study sought to utilise the susceptibility of young drivers to peer influence by using peers to design and deliver a safety intervention, following the ‘U in the Driver Seat’ model from the US. When compared to a traditional fear appeal and a control, the peer intervention group reported safer attitudes and intentions to drive safely at follow-up. Together these studies provide insight into how peers influence young drivers’ risky behaviour, and support the notion of using peer education tools in young driver safety interventions.     

Examining Externalizing Behavior Trajectories of Youth in Group Homes: Is there Evidence for Peer Contagion?

Although concerns about peer contagion are often cited in critiques of group treatments for troubled youths, few studies have examined the effects of exposure to deviant peers in residential group care settings. This study used administrative data of youth served at Boys Town, a nationally-known group care provider. Using latent class growth analysis, this study identified the externalizing behavior trajectories of youth in group care as well as the behavior trajectory of the peers with whom they lived, assessed the relationship between youth trajectory classes and individual and peer group characteristics as well as the relationship between an individual youth’s behavior pattern and the behavior pattern of proximal peers. Several results suggested the presence of peer contagion in group care: a trajectory class of gradually increasing externalizing behavior problems, the strength of deviant peer density in predicting an individual youth’s externalizing behavior trajectories and significant associations between behavior patterns of youth and proximal peers. While there is some evidence that suggests an increase in problem behavior during care, results from this study indicated that over 90% of the youth did not have an increase in problem behaviors and that positive peer influences may also be protective and inhibit problem behaviors.     

A Field Experiment Demonstrates Near Peer Mentorship as an Effective Support for Student Persistence

The attitudes and behaviors of peers can predict an individual’s own behaviors, particularly during adolescence. However experimental studies have not demonstrated how slightly older near peers can exert a positive influence on important aspects of school motivation that predict student academic achievement over time. We designed and evaluated the effects of a randomized controlled field experiment where 8th-grade participants were randomly assigned to either a mentoring treatment group or a tutoring control group, both led by randomly selected and trained high school students. As predicted, participants in the treatment group increased in their tendency to value and persist through academic difficulty compared to those in the control group, with important potential implications for academic achievement and peer mentoring programs.     

Factors Associated with Peer Sexual Harassment Victimization Among Taiwanese Adolescents

This study examined the individual and interpersonal factors of peer sexual harassment victimization among Taiwanese adolescents. A random sample of 1,376 7th to 9th grade middle school students in Taichung City, Taiwan, completed questionnaires about their demographics, delinquency, peer/teacher interaction, and experience of being sexually harassed by peers. Approximately 25.4% of the respondents had suffered peer sexual harassment during the previous semester. Boys reported more exposure to sexual harassment than did girls. Multivariate logistic regression analyses were performed separately for boys and girls. Significant risk factors of peer sexual harassment victimization for both genders included being bullied by peers and teacher maltreatment. Boys’ sexual harassment victimization was also associated with their involvement in fights. Peer relationship problems contributed to girls’ sexual harassment victimization. These findings suggested the relevance of a hostile school climate to peer sexual harassment and the gender differences in risk factors.     

Evaluation of a lag schedule of reinforcement in a group contingency to promote varied naming of categories items with children

We compared the effects of Lag 0 and Lag 1 schedules of reinforcement on children's responses naming category items in a group context and subsequent responses emitted during individual testing in which the schedule of reinforcement remained Lag 0. Specifically, we measured response variability and novel responses to categories for 3 children who demonstrated the lowest level of variability during an initial individual Lag 0 testing session. An additional 3 children who emitted a high level of variability during initial individual Lag 0 testing sessions served as peers during group sessions. Results showed that participants conformed to the Lag 1 schedule and were more likely to repeat peer responses in the group and during individual testing in the Lag 1 condition. Furthermore, the reinforcement schedule in effect during group sessions affected participants’ varied responses during individual testing, during which the reinforcement schedule remained unchanged.     

Using technology to explore social networks and mechanisms underlying peer effects in classrooms

Peer interactions among children have long interested social scientists. Identifying causal peer effects is difficult, and a number of studies have used random assignment to produce evidence that peers affect each other's outcomes. This focus by sociologists and economists on whether peers affect each other has not been matched by direct evidence on how these effects operate. The authors argue that one reason for the small number of studies in sociology and economics on the mechanisms underlying peer effects is the difficulty of collecting data on microinteractions. They argue technology reduces data collection costs relative to direct observation and allows for realistic school activities with randomly assigned peers. The authors describe a novel strategy for collecting data on peer interactions and discuss how this approach might shed light on mechanisms underlying peer influence. The centerpiece of this strategy is the use of handheld computers by middle and high school students as part of interactive math and science lessons called the Discussion Game. The handhelds collect data on interactions between students and track how students' answers evolve as they interact with different peers.     

Delinquent Peer Influence on Childhood Delinquency: The Moderating Effect of Impulsivity

A link between delinquent peer affiliations and childhood delinquency has been consistently found in the literature. However, little to no research has examined how the characteristics of an individual may impact this association. Impulsivity may be an important individual characteristic to consider, as impulsivity is associated with childhood delinquency. Accordingly, the current study examined the potential moderating effect of impulsivity on the association between peer delinquency and child delinquency in a community sample of 89 children ranging from 9 to 12 years of age (mean = 10.4 ± 1.1 yrs). Findings suggest that at low levels of impulsivity peer delinquency and child delinquency were positively associated; however at high levels of impulsivity peer delinquency and child delinquency were not statistically related. These findings may suggest that children who exhibit low levels of impulsivity are particularly vulnerable to delinquent peer influences. Implications for findings are discussed.     

The Effects of Team Context on Peer Ratings of Task and Citizenship Performance

Recent trends indicate that organizations will continue their strategic pursuit of teamwork for the foreseeable future, which will create a need for accurate assessments of individuals’ performance in teams. Although individual behaviors can be perceived and assessed by fellow team members (i.e., peers), the extent to which the team shapes perceivers’ judgments versus the target’s behavior is unclear. We conducted two studies to understand how and why team context influences peer ratings of individual performance. In study 1, we conducted cross-classified modeling on a sample of 7160 performance observations of 568 targets made by 567 perceivers, who were each members of four separate teams. Results indicated that team membership accounted for a substantially higher proportion of perceiver, relative to target, variance. In study 2, we conducted social relations modeling with a sample of 679 performance observations collected from 217 individuals nested in 46 teams to test the effects of psychological safety on perceiver, target, and team variance components. Perceptions of psychological safety accounted for proportionally larger perceiver, relative to target, variance in OCB, and task performance ratings. Altogether, team context appears to affect perceivers’ judgments of behavior more than the target’s behavior itself, implying that peer ratings sourced from different teams may not be comparable. We consider the implications for the collection and interpretation of peer performance ratings in teams and the potential implications for social cognitive theory, such that certain aspects of the team context, including psychological safety, may act as a cognitive heuristic by molding perceiver judgments of targets.

     

Does Perceived Peer Delinquency Amplify or Mitigate the Deterrent Effect of Perceived Sanction Risk?

The present article studies the interplay of perceived peer delinquency and perceived sanction risk in crime causation. Different sets of hypotheses are formulated. From Situational Action Theory (SAT), it follows that adolescents who have many delinquent friends are more frequently exposed to a crime-conducive moral context. As a consequence, they will more often feel tempted to engage in criminal behavior, which renders them more responsive to sanction risk. Rational Choice Theory (RCT) suggests that adolescents who have no or few delinquent friends are more responsive to sanction risk because these individuals have more informal costs following from punishment to fear. These hypotheses are tested with longitudinal data from the British PADS+ study. Results provide strong support for the propositions derived from SAT. Perceived peer delinquency conditions the effect of perceived sanction risk, and sanction certainty perceptions are most influential among adolescents with a large number of delinquent friends.
