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…

Despite a wealth of knowledge for factors predicting adolescent defending behaviors, it remains unknown about victims' adjustment resulting from experiencing the presence of different bystander roles in a victimization episode. This study analyzed 209 Taiwanese adolescents' reports of school-based peer victimization, perceived bystander actions in…

Sexual abuse and peer victimization often co-occur and generate similar repercussions. The current study aimed to determine the extent to which child sexual abuse is associated to peer victimization. The unique contribution of these two distinct forms of victimization to the prediction of behavior problems was also investigated in a sample of 532…

Identifying patterns of victimization continuity and discontinuity over time can inform school-based efforts to prevent and intervene with peer victimization. We conducted a four-wave longitudinal study of students through their transition from middle to high school. Participants were 135 diverse students from Grade 8 to Grade 11 who completed…

Recent years have witnessed a surge of research on cyberbullying. In this article, three studies examined prevalence rates of cyberbullying among college-age students, venues through which cyberbullying occurs, with a particular focus on social media, and perceptions of cyberbullying as a function of features of the target (e.g., peer, celebrity,…

Even though previous studies have addressed the relation between face-to-face bullying and cyberbullying, none have studied both phenomena simultaneously. In this article, we present a computer game-based method to study both types of peer aggression among youth. Study participants included fifth graders (N = 93) in two U.S. Midwestern middle…

This study examined the extent to which disability status, alone and in combination with other social identities, was associated with differential levels of exposure to peer victimization. Logistic analyses of survey responses from eleventh graders completing the 2008 Oregon Healthy Teen survey (N = 7,091) utilized an intersectional,…

Recent research highlights the role of peer victimization in students' adjustment across a variety of domains (e.g., academic, social), but less often identifies potential mediating variables. In the current study, we tested for direct effects from peer victimization to adolescents' academic behavior and alcohol use, as well as indirect effects…

This study examined the concurrent validity of the Olweus Bully/Victim Questionnaire (BVQ) in a convenience sample of 202 middle school students in central Virginia. This appears to be the first published study to compare BVQ reports of being bullied and of bullying others with independent criteria not subject to shared method variance.…

This article examines how moral disengagement, empathy, belief in a just world, and peer group normative beliefs regarding the roles of bully and defender of the victim are associated with attitudes regarding the roles of the bully and the defender of the victim. Two hundred ninety-two students from grades 6-9 participated. Results showed that…

Given the number of factors involved in bullying, the range of explanatory theory upon which one might draw is vast. Not only might one consider factors within the family, the individual, the peer group, the school and the community, but each of these could be considered from a number of different perspectives. This paper explores the issues for…

Bullying studies frequently rely on student self-report to identify bullies and victims of bullying, but research in the broader field of peer aggression makes greater use of other informants, especially peers, to identify aggressors and victims. This study compared self, peer, and teacher identification of bullies and bully victims in a sample of…

Why are students who have special educational needs at greater risk of bullying than their peers when educated in mainstream settings? This case study of one mainstream secondary school describes the various facets of the peer group dynamics that underpinned social aggression and exclusion towards students who were hearing impaired. These students…

One need not look hard to find evidence of concern related to the nature of student behavior in our schools. School violence, aggression, bullying, and harassment (e.g., racial or sexual) are often cited as challenging behaviors confronting educators and community leaders. Unfortunately, most schools address these concerns with aversive…
