Environmental influences on fighting versus nonviolent behavior in peer situations: a qualitative study with urban African American adolescents

This qualitative study explored environmental factors that influence adolescents’ responses to problem situations involving peers. Interviews were conducted with 106 middle school students (97% African American) from an urban school system. Participants were asked to describe factors that would make it easier and those that would make it more difficult for adolescents to make specific responses to problem situations. Two types of responses were presented: nonviolent responses identified as effective in a previous study, and fighting responses. Qualitative analysis identified 24 themes representing family, peer, school, and neighborhood and broader social factors that were related to both nonviolent behavior and fighting. The identification of environmental influences on fighting and nonviolent responses has important implications for efforts to reduce aggression and promote effective nonviolent responses to problem situations encountered by adolescents.

Methodological Challenges Examining Subgroup Differences: Examples from Universal School-Based Youth Violence Prevention Trials

This article reviews the literature on school-based universal violence prevention programs to illustrate key methodological challenges for investigating subgroup differences in prevention effects. The variety of potential moderating factors examined within this literature is discussed within the context of a social-ecological model. Our review of this literature identified the following methodological issues: the need for a clear a priori theoretical basis for selecting potential moderators, inflated Type I error rates that result from large numbers of comparisons, the absence of explicit tests of moderation, interpretive issues arising from a restricted range on moderator variables, the failure to report effect size estimates, the presence of potential confounding factors, and the importance of examining factors that might operate at multiple ecological levels. These points are illustrated using examples of studies, primarily within youth violence prevention research, that have identified factors within the individual, school, and community that moderate the outcomes of preventive interventions. We conclude with general recommendations for future work. These include the benefits of using the social-ecological model to provide a basis for moving from exploratory to more theory-driven confirmatory models of subgroup differences, the potential merits of qualitative research designed to identify factors that may influence the effectiveness of intervention efforts for specific subgroups of individuals, and the provision of effect size estimates and confidence intervals for effect sizes in prevention reports.

Stability and Change in Patterns of Peer Victimization and Aggression during Adolescence

This study identified classes of adolescents who differed in their patterns of reported aggression and victimization, examined the stability of these patterns, and explored factors associated with changes in patterns across time. Participants were 477 students from an urban and an adjoining county school system. The overall sample was 48% male and had an average age of 11.3 years. The urban sample was predominantly African American (80%); the county sample was primarily Caucasian (40%) and African American (38%). Self-report aggression and victimization measures completed at the beginning of sixth grade and the end of seventh grade were analyzed using latent class analyses and latent transition analyses. Support was found for four classes: nonvictimized aggressors, aggressive-victims, predominantly victimized, and well-adjusted youth. Emotion dysregulation, anxiety, and site were associated with membership in the aggressive-victim class in the expected direction, providing support for the validity of the classes. The well-adjusted class was the most stable in class membership over time; the predominantly victimized class was the least stable. In addition, nonvictimized aggressors and predominantly victimized youth were more likely than those in the well-adjusted class to transition into the aggressive-victim class. These findings suggest notable stability in aggressor/victim classes over time and emphasize the importance of developing prevention programs that target the unique needs of distinct aggressor/victim classes in adolescence.

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.

Core competencies and the prevention of youth violence

We discuss how the five core competencies for healthy adjustment in adolescence (a positive sense of self, self-control, decision-making skills, a moral system of belief, and prosocial connectedness) are represented in theories of aggression and youth violence. We then discuss research supporting the relation between these core competencies and aggressive and violent behavior in childhood and adolescence. Finally, we address the degree to which these core competencies have been included and systematically evaluated within school-based prevention programs, and we end with suggestions for future directions.

Patterns of Adolescents’ Beliefs About Fighting and Their Relation to Behavior and Risk Factors for Aggression

This study examined adolescents’ patterns of beliefs about aggression, and how these patterns relate to aggressive and prosocial behavior, and to risk factors associated with aggression. A sample of 477 sixth graders from two urban schools and a school in a nearby county completed measures of beliefs, behavior, and individual, peer and parental factors associated with aggression. Teacher ratings of participants’ behavior and emotion regulation were also obtained. The urban sample was 84% African American; the county school was in a rural fringe area with a student population that was 45% Caucasian and 40% African American. Latent class analysis of items on a beliefs measure supported hypotheses predicting three groups: (a) a Beliefs Against Fighting (BAGF) group that opposed the use of aggression (31% of the sample); (b) a Fighting is Sometimes Necessary (FSNEC) group that endorsed beliefs that fighting is sometimes necessary or inevitable (41%), and (c) a Beliefs Supporting Fighting (BSUPF) group that supported aggression across multiple contexts (28%). Differences across groups were found on race/ethnicity and family structure, but not on gender. Significant differences were also found such that the FSNEC group fell between levels of the BAGF and BSUPF groups on most measures. In contrast, the FSNEC and BAGF groups both differed from the BSUPF group, but not from each other on measures of empathy, perceived effectiveness of nonviolence and aggression, and parental messages supporting nonviolence. These differences suggest the need for tailoring prevention approaches for subgroups of adolescents who differ in their patterns of beliefs.

Early Predictors of Urban Adolescents’ Community Violence Exposure

This study examined the extent to which individual, peer, and family factors predicted the onset of community violence exposure in middle and high school, as well as the indirect effects of early factors. We were particularly interested in the timing of exposure to community violence during adolescence, and thus conducted survival analyses on data from 632 urban youth, followed from first grade through high school. Early aggressive behavior and poor academic readiness were associated with an earlier onset of community violence exposure in adolescence. The effects of early aggression on community violence exposure and victimization were accounted for, in part, by peer rejection and deviant peer affiliation; there was no evidence of moderation by gender or parental monitoring. Findings highlight potential targets for preventive interventions with youth at risk of community violence exposure.

Universal Mandatory Reporting Policies and the Odds of Identifying Child Physical Abuse

Objectives To examine the relationships between universal mandatory reporting (UMR), child physical abuse reporting, and the moderating effect of UMR on physical abuse report outcomes by report source. Methods We used a national data set of 204 414 children reported for physical abuse in 2013 to compare rates of total and confirmed reports by states or territories with and without UMR. We estimated odds and predicted probabilities of confirming a physical abuse report made by professional versus nonprofessional reporters, accounting for the moderating effect of UMR and individual-level characteristics. Results Rates of total and confirmed physical abuse reports did not differ by UMR status. Nonprofessionals were more likely to make reports in UMR states compared with states without UMR. Probability of making a confirmed report was significantly lower under UMR; this effect almost doubled for nonprofessionals compared with professional reporters. Conclusions Universal mandatory reporting may not be the answer for strengthening the protection of children victimized by physical abuse. Implementation of child protection policies must be exercised according to evidence to exert the fullest impact and benefit of these laws.

Patterns of peer- and teacher-rated aggression, victimization, and prosocial behavior in an urban, predominantly African American preadolescent sample: Associations with peer-perceived characteristics

This study investigated peer-perceived social/reputational correlates of patterns of aggression, victimization, and prosocial behavior. Participants were a predominantly African-American (i.e., 87%) sample of 320 fourth and fifth graders (45% male, Mean age=10.4years) attending six urban public elementary schools. Using latent profile analysis, profiles of peer-perceived and teacher-perceived aggressive, victimized, and prosocial youth were identified. These latent profiles were then compared on a range of peer-perceived social/reputational characteristics. Results indicated that teachers and peers identified similar profiles of normative and prosocial students. However, whereas peers distinguished between aggressive and victimized profiles, the teacher-identified victimized profile was also perceived as aggressive. Results also indicated that there was modest agreement between peers and teachers about who was involved in peer victimization. Findings underscore the importance of including both informants in efforts to identify youth involved in peer victimization.

Evaluating the Genetic Susceptibility to Peer Reported Bullying Behaviors

Bullying is a significant public health concern with lasting impacts on youth. Although environmental risk factors for bullying have been well-characterized, genetic influences on bullying are not well understood. This study explored the role of genetics on early childhood bullying behavior. Participants were 561 children who participated in a longitudinal randomized control trial of a preventive intervention beginning in first grade who were present for the first grade peer nominations used to measure early childhood bullying and who provided genetic data during the age 19-21 year follow-up in the form of blood or saliva. Measures included a polygenic risk score (PRS) derived from a conduct disorder genome wide association study. Latent profile analysis identified three profiles of bullying behaviors during early childhood. Results suggest that the PRS was significantly associated with class membership, with individuals in the moderate bully-victim profile having the highest levels of the PRS and those in the high bully-victim profile having the lowest levels. This line of research has important implications for understanding genetic vulnerability to bullying in early childhood.
