Predictors of bullying and victimization in childhood and adolescence: A meta-analytic investigation.

Research on the predictors of 3 bully status groups (bullies, victims, and bully victims) for school-age children and adolescents was synthesized using meta-analytic procedures. The primary purpose was to determine the relative strength of individual and contextual predictors to identify targets for prevention and intervention. Age and how bullying was measured were also considered as moderators. From an original pool of 1,622 studies conducted since 1970 (when research on bullying increased significantly), 153 studies were identified that met criteria for inclusion. A number of common and unique predictors were found for the bully status groups. The implications of the meta-analytic findings for future research on bullying and victimization prevention and intervention are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
