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…

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…

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…

We examined bullying victimization spanning from before the pandemic to the two school years post COVID-19 onset in adolescents. We used survey data from Canadian secondary school students collected during the 2019-20, 2020-21, and 2021-22 academic years. Generalized Estimating Equations models were used to estimate the population average odds of…

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…

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…

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…

Although there has been an increase in research on support for campus carry laws, few studies have examined how these laws influence campus safety. Using longitudinal data from a university sample, this study compares measures of campus safety before and after the adoption of a campus carry law. We found statistically significant increases in…

School security measures have become commonplace in recent years. Still, little quantitative research has examined how this trend shapes students' perceptions of school. This study examines how students' exposure to school security relates to their sense of school connectedness, with particular attention to the difference between white and…

The aims of the current study were to provide the first Australian prevalence estimates of sexual harassment in adolescents, explore gender differences in form and frequency of harassment, and investigate demographic and weight status correlates. A total of 4098 adolescents (47.3% boys), aged 11 to 19 years from government and non-government…

Witnessing violence can negatively affect students' outcomes, but their friendships may mitigate those effects. This study investigated the extent to which seeing someone shot in the last year related to seven school-related outcomes. Additionally, it examined the extent to which prosocial and deviant friends moderate these relationships. This…

Goffman's theory of total institutions and Fanon's theory of violence were used to explain student protests and violence in Kenyan secondary schools. Youth violence around the world is not a new phenomenon. However, the persistence, frequency, and intensity of violence, and their consequences beg for logical explanations and remedies. This study…

This study examined longitudinal changes in peer network selection and influence associated with self-reported antisocial behavior (AB) and violent behavior (VB) over the course of middle school in a sample of ethnically diverse adolescents. Youth and families were randomly assigned to a school-based intervention focused on the prevention of…

Immigrant youth are at risk of experiencing harassment in school; however, we have only limited understanding of what makes youth harass their peers on ground of their ethnic origin. To address this major limitation, we examined (a) whether youth's negative attitudes toward immigrants impact their engagement in ethnic harassment over time and (b)…

In the past 2 decades, correlational and experimental studies have found a positive association between violent video game play and aggression. There is less evidence, however, to support a long-term relation between these behaviors. This study examined sustained violent video game play and adolescent aggressive behavior across the high school…
