Although the majority of students disapprove of aggressive behavior in school, only some of them intervene when witnessing aggression between their classmates. This study examines how bystanders might be activated to support the victims of aggression in school. The effectiveness of a Bystander Intervention Training for students, implemented via teachers, was evaluated. Data from 22 training and 26 control classes were collected at three occasions and analyzed using multivariate multilevel analyses. The primary evaluation criterion was the change in frequencies of aggression and active vs. passive bystander behavior. The training reduced passive bystander behavior and victimization over time. Training effects were stronger for classes with high implementation quality. Recommendations for the implementation of the training will be discussed. [less ▲]

Despite significant overlaps between victim status in traditional forms of bullying and cyberbullying, and qualitative results about self-reported reasons for cyberbullying, the role of revenge and retaliation as a motive to engage in acts of cyberbullying has not yet been examined systematically. As a first step, this study investigates whether and to what extent traditional victims, when they become cyberbullies, actually choose their former (traditional) perpetrators as targets of their own cyberbullying behavior. Furthermore, the impact of individual differences in relevant traits, such as vengefulness and justice sensitivity, on the choice of cybervictims is examined. Data from 473 students were collected via an online survey. Of these, 149 were identified as traditional victims/cyberbullies. Results show that traditionally bullied students indeed tend to choose their former perpetrators as cybervictims, and that individual differences play a role in the choice of their victims. Implications for further research, as well as for interventions and prevention programmes, are discussed. [less ▲]
