Direct and Vicarious Violent Victimization and Juvenile Delinquency: An Application of General Strain Theory*

Using a national probability sample of adolescents (12–17), this study applies general strain theory to how violent victimization, vicarious violent victimization, and dual violent victimization affect juvenile violent/property crime and drug use. In addition, the mediating effect and moderating effect of depression, low social control, and delinquent peer association on the victimization–delinquency relationship is also examined. Based on SEM analyses and contingency tables, the results indicate that all three types of violent victimization have significant and positive direct effects on violent/property crime and drug use. In addition, the expected mediating effects and moderating effects are also found. Limitations and future directions are discussed.

Is teen court the best fit? Assessing the predictive validity of the Teen Court Peer Influence Scale

Purpose Despite the increased use of teen courts for first time, non-violent juvenile offenders, there has been little research examining the decision-making processes regarding which offenders are best suited for this type of intervention. The Teen Court Peer Influence Scale (TCPIS) was developed to assist juvenile justice officials in making these determinations. The purpose of the present research is to determine the predictive validity of the TCPIS. Methods The TCPIS was administered to a nonprobability sample of teen court participants in Florida (N = 404) between September 2006 and February 2007. Dependent measures for the validity analysis were developed from the Youth Self-administered Questionnaire and included social bonds, prosocial attitudes, delinquent peer associations, positive perceptions of teen court, and perceived delinquency. Results All hypotheses were supported with the TCPIS global score accounting for a significant amount of variance among each of the delinquency measures strengthening the predictive validity of the measure. Conclusions These preliminary findings are positive regarding the predictive validity of the TCPIS. With additional research, the TCPIS could be a useful tool for decision-makers regarding which juvenile offenders are the best fit for teen court diversion programs.

Genetic and Environmental Influences in Delinquent Peer Affiliation: From the Peer Network Approach

Mainstream criminologists have long maintained that delinquent peer group formation is largely a function of family—environmental variables and have ignored self-selection into peer groups because of genetic proclivities. A small number of recent studies, however, suggest that genes are implicated in delinquent peer affiliation. Given the potentially far-reaching implication of such research findings, the authors replicate Beaver, Wright, and DeLisi’s (2008) study, among others, using a direct measure of peer delinquency. That is, the authors analyze the Add Health genetic data employing a measure of peer delinquency which is based on the delinquency counts reported by peers themselves rather than respondents’ self-reports. Even employing this alternative measure, their results clearly support the original study, providing further evidence of genetic underpinnings of delinquent peer group formation.

Parents as Moderators of the Impact of School Norms and Peer Influences on Aggression in Middle School Students

This study examined parenting variables as protective factors to reduce the influence of school and peer risk factors on adolescents' aggression. Five waves of data spanning 3 years were collected from 5,581 students at 37 schools who began the 6th grade in 2001 or 2002. Class-level and perceived school norms supporting aggression, delinquent peer associations, parental support for fighting and support for nonviolence, and parental involvement were each associated with physical aggression across all waves. Each parenting variable moderated 1 or more risk factors, with the magnitude of many effects varying by gender and decreasing over time. Implications for the role parents may play in reducing the impact of school and peer risk factors for aggression are discussed.

Normative Beliefs and Self-Efficacy for Nonviolence as Moderators of Peer, School, and Parental Risk Factors for Aggression in Early Adolescence

This study examined the direct effects of beliefs about aggression and nonviolence on physical aggression and their role as protective factors that buffer adolescents from key risk factors in the peer, school, and parenting domains. Multilevel analyses were conducted on data from 5,581 adolescents representing two cohorts from 37 schools in four communities collected at the beginning and end of the sixth grade and at the end of the following 2 school years. Individual norms for aggression at Wave 1 moderated relations of delinquent peer associations and parental support for fighting with physical aggression. Self-efficacy for nonviolence at Wave 1 moderated relations of school risk, delinquent peer associations and parental support for fighting with physical aggression. There was clearer evidence for protective effects for self-efficacy for nonviolence for girls than for boys.

Proactive and Reactive Aggression and Physical Activity

The current study examined relations between physical activity and proactive and reactive aggression. Additionally, physical activity was examined as a potential moderator of the associations between these subtypes of aggression and peer delinquency. Relations were examined in a community recruited sample of 89 children (56% male, 74% Caucasian) ranging from 9 to 12 years of age (M = 10.44, SD = 1.14). As expected, physical activity was negatively related to proactive aggression and unrelated to reactive aggression. Moreover, physical activity moderated the relation between proactive aggression and peer delinquency, such that at high levels of physical activity, proactive aggression was unrelated to peer delinquency but at low levels of physical activity, proactive aggression was positively associated with peer delinquency. Thus, physical activity may be an important factor to consider when understanding the link between aggression and other problem behavior, as physical activity appears to impact the link between proactive aggression and delinquent peer affiliations.

Juvenile delinquency and adolescent fatherhood.

This study examined ecological risk factors associated with teen paternity in a sample of 2,931 male adolescents coming to the attention of juvenile courts across five midwestern counties. In contrast to previous studies documenting significantly higher rates of teen paternity among African American youth, we found that the European American court-involved youth in our sample were as likely to be teen fathers as their African American counterparts. However, an in-depth examination of the social ecologies of these court-involved youth revealed significant racial differences (regardless of the paternity status), with African American males reporting more prior offenses, delinquent peer associations, traumatic pasts, risky sexual behaviors, and educational risks as compared to European American youth, who reported greater involvement in substance use. Furthermore, logistic regression analyses revealed that after controlling for age and racial background, youth who reported greater exposure to trauma and prior offenses had significantly greater odds of having fathered a child. Surprisingly, youth who were teen fathers reported lower rates of behavioral problems as compared to their nonfathering peers. Given the cross-sectional nature of our data, interpretation of this result is limited. Overall, our findings underscore the need for developing a comprehensive understanding of the ecological risk and protective factors present in the lives of teen fathers coming in contact with the juvenile justice system, as an essential first step in designing effective and relevant intervention programs and services for this at-risk population.

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.

A Multivariate Analysis of Youth Violence and Aggression: The Influence of Family, Peers, Depression, and Media Violence

To examine the multivariate nature of risk factors for youth violence including delinquent peer associations, exposure to domestic violence in the home, family conflict, neighborhood stress, antisocial personality traits, depression level, and exposure to television and video game violence. A population of 603 predominantly Hispanic children (ages 10-14 years) and their parents or guardians responded to multiple behavioral measures. Outcomes included aggression and rule-breaking behavior on the Child Behavior Checklist (CBCL), as well as violent and nonviolent criminal activity and bullying behavior. Delinquent peer influences, antisocial personality traits, depression, and parents/guardians who use psychological abuse in intimate relationships were consistent risk factors for youth violence and aggression. Neighborhood quality, parental use of domestic violence in intimate relationships, and exposure to violent television or video games were not predictive of youth violence and aggression. Childhood depression, delinquent peer association, and parental use of psychological abuse may be particularly fruitful avenues for future prevention or intervention efforts.

Evidence of Genetic and Environmental Effects On the Development of Low Self-Control

A body of research has revealed that low self-control is one of the strongest and most consistent predictors of antisocial behaviors. As a result, there is great interest in identifying the factors that cause variation in levels of self-control. Much of this work has centered on identifying the effects that social factors, such as parental socialization, have on self-control. More recently, however, there has been research revealing that levels of self-control are scripted by genetic factors as well as environmental factors. The current study examines whether a polymorphism (5HTTLPR) in the serotonin transporter gene and exposure to delinquent peers are associated with levels of self-control. Analysis of the National Longitudinal Study of Adolescent Health indicates that the 5HTTLPR polymorphism interacted with a measure of delinquent peer affiliation to predict variation in self-control during adolescence and adulthood. Implications for theories of crime causation are discussed.

Genetic and Environmental Influences on Levels of Self-Control and Delinquent Peer Affiliation

Despite the fact that low self-control and exposure to delinquent peers are two of the most robust and consistent predictors of crime, delinquency, and antisocial behavior, much remains unknown about what causes self-control to develop and what causes youths to befriend antisocial peers. This study estimated the relative effects of environmental and genetic factors on levels of self-control and contact with delinquent peers in a sample of twins from the National Longitudinal Study of Adolescent Health (Add Health). DeFries-Fulker analysis of the Add Health data revealed that both self-control and contact with drug-using friends were influenced by genetic factors and the nonshared environment, whereas the shared environment exhibited relatively small and inconsistent effects. Implications for self-control theory and social learning theory are discussed.

Nonshared Environmental Influences On Sibling Differences in Externalizing Problem Behavior

Using a difference scores approach, this study examines the effects of sibling differences in experiences both within and outside the home on differences in externalizing problem behavior. The results suggest that differences in parental monitoring, sibling interaction, and delinquent peer association are significantly related to sibling differences in externalizing behavior. These effects, however, appear to differ based on the sex composition of the sibling pair. Differential sibling interaction was most consistently related to differences in externalizing behavior. Differential peer association and differential parental monitoring were only significantly related to sibling differences in externalizing behavior for sister pairs and mixed-sex pairs, respectively. The importance of considering nonshared environmental influences in explaining sibling differences in behavior is discussed.

Risks of Non-Familial Violent Physical and Emotional Victimization in Four Asian Ethnic Groups

There is a paucity of research addressing victimization among Asian and Southeast Asian youth. A community-based sample of 329 Chinese, Cambodian, Lao/Mien, and Vietnamese youth were interviewed in a face-to-face format. Non-familial physical and emotional victimization were explored in relation to risk factors. Results revealed that reporting of violent physical victimization was generally greater among males than females, and greater among females than males for emotional victimization. Southeast Asian youth were more likely to experience victimization than Chinese youth. Violent offending, drug use, and delinquent peer affiliation significantly increased the odds of physical victimization, whereas more distal influences such as neighborhood exerted less influence. For emotional victimization, self-esteem and dating abuse was most salient. Study highlighted the need to consider victimization disaggregated by ethnicities as well as cultural factors that have thus far been eclipsed in most empirical studies of youth victimization.

A Longitudinal Study of Cocaine Use Among Juvenile Arrestees

ABSTRACT We report the results of latent growth model analyses examining the continuity of cocaine use among adolescents. This study examined a sample of 278 justice-involved juveniles completing at least one of three follow-up interviews as part of a National Institute on Drug Abuse funded study. Latent growth models were analyzed examining (1) changes in cocaine use over time; (2) the effects of sociodemographic characteristics on cocaine use over time; and (3) the effects of family problem characteristics, deviant peer associations, physical abuse, sexual victimization, and emotional/psychological functioning on cocaine use over time. The results of our analyses indicated that cocaine use among these youths continued over time. Further, consistent with findings from existing literature, cocaine use was significantly related to drug using and delinquent peer associations, and marginally related to family problems with the justice system. Implications for policy and intervention service needs are discussed.

Parents, Friends, and Serious Delinquency

Family context has been identified as a central domain in the study of delinquency, particularly during early childhood. As youth enter adolescence peer associations become a much stronger influence. Using a sample of preadolescent youth, this research examines the effect of family and peer relationships on delinquency. Specifically, path analysis is used to test the effects of family structure, parental supervision, and parental attachment on serious delinquent behavior to determine if a youth's family life has a unique effect on serious delinquent behavior, or if familial relationships are mediated by peer associations. Findings suggest that parental variables are indirectly related to subsequent, serious delinquency, whereas delinquent peer association exerts a strong, direct effect. The study offers insight into the roles that a youth's family life and peer associations play in explaining delinquent behavior. In addition, the findings highlight the need for interventions that encourage pro-social relationships among youth.

School-related Risk and Protective Factors Associated with Truancy among Urban Youth Placed at Risk

Truancy is a serious concern in the United States. Its negative effects are so pervasive that in 2003 the Office of Juvenile Justice and Delinquency Prevention named truancy prevention a national priority. Effective prevention of truancy requires a thorough understanding of the characteristics that describe truant youth as well as factors that may put them at risk for truancy. Unfortunately, surprisingly little is known about the correlates and/or causes of truancy. In this paper we explore associations between truancy and several salient school-related risk and protective factors among a sample of youth who grew up in socially disorganized neighborhoods of Denver, CO. We demonstrate that several school-related risk and protective factors are associated with truancy. Perhaps most importantly, we identify that the two most robust predictors are school performance and involvement with delinquent peers, and that these two variables form a synergistic relationship in which the relationship between delinquent peer association and truancy is mitigated among students who perform well in school. EDITORS' STRATEGIC IMPLICATIONS: The authors use data from a large probability sample drawn from neighborhoods with high crime rates to identify key correlates of truancy. They also draw attention to the dearth of efficacious truancy prevention efforts in spite of the magnitude of the problem.

Delinquent peer affiliation and conduct problems: A twin study.

Many putative environmental risks correlate with individuals' genotypes. The association between delinquent peer affiliation and conduct problems may occur because of shared genetic liability. Five hundred fifty three monozygotic and 558 dizygotic twin pairs, aged 11 to 18 years, were assessed for delinquent peer affiliation and conduct problems. The authors investigated whether genes contribute to both delinquent peer affiliation and the correlation between delinquent peer affiliations and conduct problems. Delinquent peer affiliation was influenced by genetic, shared environmental, and nonshared environmental factors; genetic factors also contributed to the correlation between delinquent peer affiliations and conduct problems, providing evidence for genotype-environment correlation. The magnitude of the genetic variance of conduct problems was contextually dependent on levels of delinquent peer affiliation and was greater at higher levels of delinquent peer affiliation.

Childhood behavior problems and peer selection and socialization: Risk for adolescent alcohol use

To date, research examining the role of peers in the development of substance use has focused almost exclusively on externalizing behavior problems without considering internalizing behavior problems. This is a notable omission in the literature, because there is some evidence to suggest that internalizing behavior increases risk for substance use, and peers are considered to be among the strongest proximal influences of substance use. The current study considered both internalizing and externalizing behavior problems and examined peer socialization and selection models of alcohol use using a 2-year longitudinal design. We examined potential reciprocal relations between internalizing and externalizing behavior and affiliations with delinquent peers, and how these variables predicted initiation of alcohol use. Participants were 86 children (71% male) ranging from 9–12 years of age ( M = 10.87). Results were consistent with socialization, whereby delinquent peer affiliations were associated with increases in externalizing behavior, and subsequently early initiation of alcohol use. There was also evidence to suggest that internalizing behavior served as a protective factor for delinquent peer affiliations and for early initiation of alcohol use. Implications of these findings for prevention and intervention efforts are discussed.

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.
