Peer victimization in schools most often occurs in the presence of bystanders. When bystanders intervene on behalf of the victims, they are often successful in stopping the victimization. Defender self-efficacy (i.e., the belief in one's ability to successfully defend victims) has consistently been associated with greater defending and less…

Background: Addressing school violence is an important public health goal. To assess the role of school mental health curricula in violence prevention, we evaluated effects of an anti-stigma curriculum on violence victimization/perpetration. Methods: An ethnically/socioeconomically diverse sample of 751 sixth-graders (mean age 11.5 years) across…

This study examined beliefs about aggression and self-efficacy for nonviolent responses as mediators of longitudinal relations between exposure to violence and physical aggression. Participants were a predominantly African American (79%) sample of 2705 early adolescents from three middle schools within urban neighborhoods with high rates of…

To identify factors in adolescence that predict the onset of sexual violence in adolescence and young adulthood. Data were analyzed from six survey waves of the longitudinal Growing up with Media Study (2008-2018) conducted in the USA. Participants were 778 youth 13-18 years old at baseline, who completed online surveys assessing sexual violence…

Urban adolescents experience high rates of exposure to community violence, which is associated with sleep problems. However, less is known about the prospective relationships between community violence exposure and sleep problems across adolescence. This study investigated reciprocal relationships between community violence exposure and sleep…

Assessing change in campus interpersonal violence over time is an important step to understand the nature and prevalence of students' victimization experiences. Using a repeated cross-sectional campus survey of interpersonal violence from a large southern university, this article tracks the change of students' victimization experiences over a…

Research finds that vicarious strain significantly predicts juvenile delinquency. However, no studies have examined the influence of vicarious health strain on youth behavior despite the fact that when individuals directly experience poor health, there is a greater likelihood of crime and delinquency. Using a sample of youth from the Project on…

Although dating violence poses a serious threat to adolescents' health and well-being around the globe, little evidence is available for Europe in general and Switzerland in particular. Also, evidence on the role of cognitive predictors related to a more general justification of aggressive behavior and gender-based violence is lacking. Therefore,…

Identifying developmental patterns in intergroup contact and its relation with bias is crucial for improving prevention strategies around intergroup relations. This study applied time-varying effects modeling (TVEM) to examine age-based changes in relations between contact and bias in a divided community that included 667 youth (M age = 15.74, SD…

Objective: This study examined if empathy was a significant moderator of several empirically established risk factors for sexual violence perpetration among college men. Participants: Data are from 544 college men who participated in a longitudinal study from 2008 to 2011 at a large, public university. Methods: Participants completed a self-report…

Muslim masculinities have been problematically conflated with notions of radicalisation, terrorism and violent extremism. There has been…

In Vietnam, school violence is a serious problem; yet, little is known about the factors explaining this phenomenon. The current study looked at the role of normative beliefs approving aggression in the development of overt aggressive behavior. Using a short-term longitudinal design with three waves (4-month interval), this study examined the…

Growing evidence of the prevalence of school-related gender-based violence (SRGBV) has raised concerns about negative effects on education. Previous quantitative research on this topic has been limited by descriptive and cross-sectional data. Using longitudinal data from the Malawi Schooling and Adolescent Study, we investigate associations…

Developmental trajectories of bullying perpetration were examined across 5 waves of longitudinal panel data among Midwestern middle school students. This study explained an unobserved heterogeneity of subgroups, each having the similar pattern of trajectories and investigated antecedents and consequences of class membership. Growth-mixture…

This paper contributes to the understanding of how shifting time, space and subject positions can impact on the political habitus of border-crossing students. Employing in-depth interview data from a longitudinal project involving 31 mainland Chinese students whose higher education journeys converged in Hong Kong, it argues that it is often…
