A meta‐analysis of predictors of bullying and victimisation in adolescence

Bullying is common and harms all involved, yet there is no clarity regarding factors that influence bullying and victimisation for adolescent samples. This meta-analysis aims to synthesise the literature and identify reliable risk and protective factors to adolescent bullying and victimisation. A systematic search of the literature using databases; PsycINFO and Scopus, was undertaken to identify relevant publications from 1985 until July 2014. Inclusion criteria included longitudinal data, an adolescent sample and a focus on predictive factors of bullying or victimisation. From 4698 articles identified, 18 were included. Four predictors of victimisation (prior victimisation, conduct problems, social problems and internalising problems) and four predictors of bullying (conduct problems, social problems, school problems and age) were identified. The literature provides little consistency in predictors assessed and replication is needed for clarification, however, social problems and conduct problems are consistent risk factors and a potential focus for future interventions.
