Many behavioural and emotional characteristics are associated with children's peer relationships. The purpose of this study is to examine behavioural and emotional strengths of sociometrically popular, rejected, controversial, neglected, and average children. 773 third-grade children (51% girls) are assessed with a sociometric questionnaire and…

The systematic review by Sommer, Leuschner, and Scheithauer ("International Journal of Developmental Science" v8, n1-2, p3-24, 2014) includes 126 school shooting cases from 13 countries. This comprehensive review provides a valuable synthesis of a topic largely discussed in school shooting research: The role of bullying and peer…

A plethora of studies have appeared which argue that, prior to their attack, the perpetrators of school shootings had experienced intense conflicts and problematic relations (e.g. bullying) with peers and teachers, and were on the periphery of the schools' social life. This in turn resulted in the perpetrators' view of themselves as marginalized…

We tested whether gender-specific vs. common classroom norms were more powerful moderators of the association between a risk factor (rejection) and peer victimization among girls and boys. The participants were 1220 elementary schoolchildren from grades 4-6 (with 10-13 years of age). We compared different multilevel models including combined vs.…

This study focused on the dyadic defending relationships of victimized children in grades 3, 4, and 5 (N = 7481 children from 356 school classes, mean ages 10-12 years). Most of the victims (72.3%) had at least one defender. Being defended was positively related to victims' adjustment and social status. Analyses on victim-defender dyads showed…

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…

This longitudinal research was designed to examine the prevalence and co-occurrence of peer problems such as rejection, withdrawal, loneliness, bullying, and victimization experienced by children (99 boys, 80 girls) in their everyday lives at daycare, in preschool and first grade of school--each successive spring--at the ages of 5, 6, and 7.…

We examined whether the bystanders' behaviors in bullying situations influence vulnerable students' risk for victimization. The sample consisted of 6,980 primary school children from Grades 3-5, who were nested within 378 classrooms in 77 schools. These students filled out Internet-based questionnaires in their schools' computer labs. The results…

Three studies examined preadolescents for the relation between perceived deviance and negative peer reactions. In the first study, perceived deviance was related to social rejection. In the second and third studies, children's perceptions of responsibility for deviance predicted interpersonal affect and the degree to which the deviant person was…
