Sibling Influences on Adolescent Delinquent Behaviour: An Australian Longitudinal Study

This article examines sibling influences on adolescent delinquency at age 14, using data from an Australian longitudinal study of 374 same- and mixed-sex sibling pairs. Based on maternal and self-reports, a moderately strong association between siblings' delinquency is found. The relationship remains significant controlling for childhood aggression and family environment factors measured during childhood (age 5) and adolescence (age 14), using both standardized instruments and new scales. This effect varies according to the sex composition of the sibling pair and is stronger for males and those whose parents have been arrested. The need for increased attention to sibling influences by researchers and prevention practitioners is discussed

Gender differences in the effects of exposure to intimate partner violence on adolescent violence and drug use

Objective This study investigated the long-term effects of exposure to intimate partner violence in the home on adolescent violence and drug use and gender differences in these relationships. Although the general relationship between exposure to IPV and negative outcomes for youth has been demonstrated in past research, gender differences in the effects of IPV on adolescents have been rarely assessed using longitudinal data. Methods Longitudinal data was obtained from 1,315 adolescents and their primary caregivers participating in the Project on Human Development in Chicago Neighborhoods (PHDCN). The sample was 51% female and ethnically diverse (45% Hispanic, 37% African-American, and 14% Caucasian). Two waves of data were assessed to examine the effects of exposure to IPV, reported by caregivers when their children were aged 12 and 15, on violence and drug use, reported by adolescents 3 years later. Multivariate statistical models were employed to control for a range of child, parent, family, and neighborhood risk factors. Results Exposure to IPV did not significantly predict subsequent violence among males or females in multivariate analyses. IPV exposure was significantly related to the frequency of drug use for females but did not predict drug use among males. This gender difference was not statistically significant, however, which suggests more similarities than differences in the relationship between exposure to IPV and subsequent violence and drug use. Conclusions This study supports prior research indicating that exposure to IPV can negatively impact adolescent development, but it suggests that these effects may be more likely to influence some outcomes (e.g., drug use) than others (e.g., interpersonal violence). The findings also emphasize the need for additional research examining the overall impact of IPV on adolescent problem behaviors and gender differences in these relationships, including longitudinal studies and investigations that control for a range of other important predictors. A better understanding of these relationships can help inform intervention efforts aimed at ensuring that adolescents living in violent households receive timely and appropriate services to help prevent the occurrence of future problem behaviors

The Cycle of Violence in Context: Exploring the Moderating Roles of Neighborhood Disadvantage and Cultural Norms

Although the cycle of violence theory has received empirical support (Widom, 1989a, 1989b), in reality, not all victims of child physical abuse become involved in violence. Therefore, little is known regarding factors that may moderate the relationship between abuse and subsequent violence, particularly contextual circumstances. The current investigation used longitudinal data from 1,372 youth living in 79 neighborhoods who participated in the Project on Human Development in Chicago Neighborhoods (PHDCN), and it employed a multivariate, multilevel Rasch model to explore the degree to which neighborhood disadvantage and cultural norms attenuate or strengthen the abuse–violence relationship. The results indicate that the effect of child physical abuse on violence was weaker in more disadvantaged communities. Neighborhood cultural norms regarding tolerance for youth delinquency and fighting among family and friends did not moderate the child abuse–violence relationship, but each had a direct effect on violence, such that residence in neighborhoods more tolerant of delinquency and fighting increased the propensity for violence. These results suggest that the cycle of violence may be contextualized by neighborhood structural and cultural conditions

The Effects of Neighborhood Context on Youth Violence and Delinquency: Does Gender Matter?

This study examined the effects of neighborhood structural and social characteristics on offending among girls and boys aged 8–17 residing in 80 Chicago neighborhoods. The results demonstrated gender differences in contextual effects, although not in ways predicted by social disorganization theory. Collective efficacy and concentrated disadvantage were not significantly associated with self-reported offending among males. Among females, collective efficacy was related to higher rates of general delinquency and violence, while disadvantage reduced the likelihood of self-reported violence. These outcomes suggest that neighborhoods may impact individual offending in complex ways and highlight the importance of considering gender when researching contextual effects on youth offending

Exposure to Intimate Partner Violence: Does the Gender of the Perpetrator Matter for Adolescent Mental Health Outcomes?

Youth who are exposed to intimate partner violence (IPV) between their parents may be at increased risk for a multitude of behavioral and emotional problems, including mental health problems such as depression, anxiety, posttraumatic stress disorder (PTSD), and internalizing symptoms (Fergusson & Horwood, 1998; Finkelhor, Ormond, & Turner, 2009; Graham-Bermann, DeVoe, Mattis, Lynch, & Thomas, 2006; Zinzow et al., 2009). Research also suggests that males and females may react differently to being exposed to parental violence, although most of the findings in this area are mixed with regard to mental health outcomes. For instance, some evidence suggests that male witnesses are more likely to develop externalizing behaviors and females are more likely to suffer from internalizing disorders (Clements, Oxtoby, & Ogle, 2008; Kennedy, Bybee, Sullivan, & Greeson, 2010; Moylan et al., 2010; Yates, Dodds, Sroufe, & Egeland, 2003), whereas other studies have found that girls exposed to IPV are more likely than boys to demonstrate externalizing problems such as anger (Sigfusdottir, Farkas, & Silver, 2004). Yet others have found no gender differences in these outcomes (Fergusson & Horwood, 1998; Kitzmann, Gaylord, Holt, & Kenny, 2003; Sternberg, Baradaran, Abbott, Lamb, & Guterman, 2006)

Neighborhood Parks and Playgrounds: Risky or Protective Contexts for Youth Substance Use?

Neighborhood parks and playgrounds are thought to reduce the stressors of disorganized urban environments by adding greenspace and fostering community cohesion, and, in doing so, may reduce crime and delinquency. Yet, they may also foster criminal behaviors, including substance use, as they can provide areas for would-be offenders to gather without surveillance or fear of being caught. This study provides one of the first examinations of the relationship between the number of parks and playgrounds in a neighborhood and adolescent substance use. To do so, we analyze data from 1,584 youth living in 76 neighborhoods in Chicago. Using multivariate, multilevel Rasch models that control for many other factors that may affect adolescent substance use, we find that youth living in areas with more parks and playgrounds have a greater odds of engaging in substance use compared with those living in areas with fewer parks and centers

Penny for Your Thoughts? The Protective Effect of Youths’ Attitudes Against Drug Use in High-Risk Communities

Individual-level attitudes about drugs are strong predictors of substance use among adolescents, and aggregate-level community norms regarding deviancy and drug use may influence youth attitudes as well as their drug use. This study examined the direct effects of neighborhood norms about deviance, disadvantage, immigrant concentration, and residential stability on youths’ attitudes about drug harmfulness as well as their variety of past month substance use. The moderating effect of community norms on the relationship between youth attitudes and drug use was also examined. Results suggest that community norms favorable to deviance and drug use reduced youth’s attitudes that drugs were harmful. Further, youth’s perceptions of drug harmfulness significantly reduced their substance use in the past month. Neighborhood concentrated immigration also significantly reduced substance use. Finally, living in areas where norms were favorable to deviance enhanced the protective effect of youths’ perceptions. Implications for research and substance use prevention strategies are discussed

Victimization Experiences and Adolescent Substance Use: Does the Type and Degree of Victimization Matter?

Evidence indicates an association between victimization and adolescent substance use, but the exact nature of this relationship remains unclear. Some research focuses solely on the consequences of experiencing indirect victimization (e.g., witnessing violence), others examine direct victimization (e.g., being personally victimized), and still others combine both forms of victimization without assessing the relative impact of each on substance use. Furthermore, many of these studies only assess these relationships in the short-term using cross-sectional data. This study uses data from the Project on Human Development in Chicago Neighborhoods (PHDCN) to explore the impact of experiencing only indirect victimization, only direct victimization, both forms of victimization, and no victimization on substance use at two time points during adolescence. We find that of those adolescents who are victimized, the majority experience indirect victimization only, followed by experiencing both forms of victimization, and experiencing direct victimization only. Each of the victimization experiences were associated with increased contemporaneous substance use, with the strongest effects for those experiencing multiple forms of violence. For all victims, however, the impact on substance use declined over time

Exposure to violence, substance use, and neighborhood context

Adolescent exposure to violence and substance use are both public health problems, but how neighborhood context contributes to these outcomes is unclear. This study uses prospective data from 1416 adolescents to examine the direct and interacting influences of victimization and neighborhood factors on adolescent substance use. Based on hierarchical Bernoulli regression models that controlled for prior substance use and multiple individual-level factors, exposure to violence significantly increased the likelihood of marijuana use but not alcohol use or binge drinking. There was little evidence that community norms regarding adolescent substance use influenced rates of substance use or moderated the impact of victimization. Community disadvantage did not directly impact substance use, but the relationship between victimization and marijuana use was stronger for those in neighborhoods with greater disadvantage. The results suggest that victimization is particularly likely to affect adolescents’ marijuana use, and that this relationship may be contingent upon neighborhood economic conditions
