This study examined whether participating in the ViSC social competence program is able to reduce different types of reported problem behaviors including bullying perpetration and victimization as well as promoting various social competencies in elementary school children. Two wave longitudinal self-report and teacher report data was available…

The effectiveness of the Viennese Social Competence (ViSC) programme on various bullying-related teacher variables was examined at two time points with a quasi-experimental intervention-control group design. In Austria, Cyprus, and Turkey, teachers participated in a series of in-school trainings and implemented an anti-bullying prevention…

This study examines how bullies, victims, bully-victims, and uninvolved adolescents perceive the activities of the class project of the ViSC social competence program. The ViSC program is a whole school socio-ecological anti-bullying program that was implemented in 43 classes, grade 7, 8, and 9, in three Cypriot schools. A sample of 778…

This study investigated whether teachers' perceptions of school collegial climate characteristics (teacher-leadership collaboration, teacher-teacher collaboration, and teacher-teacher communication) are associated with teachers' active responses to…

The goals of this study were (1) to identify groups of bullies and victims, (2) to investigate level differences in depression, peer relationships, and academic variables, and (3) to examine how peer relationships and academic variables were associated with depression in these groups. The sample comprised 1,451 students (48.6% girls) aged 10-15…

The ViSC program is the first evidence based anti-bullying program implemented in Turkey. A quasi-experimental longitudinal control group design comprising six schools and 26 classes was realized to examine the program effectiveness regarding different forms of perpetration and victimization. The effectiveness of two dosages of…

It is well-documented that cyberbullying and victimization co-occur with traditional forms indicating that they share similar mechanisms. Therefore, it was hypothesized that the general antibullying program ViSC might also be effective in tackling these new forms of bullying. A longitudinal randomized control group design has been applied to…

This study was an investigation of individual and contextual predictors for same-cultural friendship preferences among non-immigrant (N = 125), Turkish (N = 196) and former Yugoslavian (N = 256) immigrant youths (M age = 14.39 years) in 36 multicultural classes. At the individual level age, gender, cultural group, number of friends, and…

Despite the rapid increase in immigration all over Europe and concerns expressed for the adjustment of immigrant children and young people, studies on peer victimisation among them are scarce. By combining the predictions of the acculturative stress model with the social-ecological perspective of peer victimisation, this study compared different…

This study (a) compared native Finns and immigrant children with respect to different forms of peer victimization and (b) tested whether intrapersonal (e.g., depression) and interpersonal (e.g., peer rejection) risk factors help to explain the association between immigrant status and peer victimization. The sample was drawn from the first phase of…

The present study concurrently analyzed risk and protective factors on the individual and the class level related to bullying and victimization in ethnically diverse schools. The sample derived from the pre-test data of a national intervention evaluation study in Austria (ViSC) and comprised 1,450 students (48.8% girls) aged 11-15 (M = 12.31) from…
