Objective: Because of the highly controversial views about school violence prevention and changes to the Juvenile Care Act, this study was aimed to identify the pathways of bullying perpetration. Methods: The sample for this study included 1,508 families; adolescents (ages 11-18 years) and their parents who participated in the 2013 Panel Study on Korean Children. The data were analyzed using SPSS and AMOS. Results: Peer violence victimization, a sense of community, internet/mobile phone addiction had direct effects on bullying perpetration. Peer violence victimization and family relationship had indirect effects on bullying perpetration through a sense of community and internet/mobile phone addiction. The effect size (R2) of pathways to bullying perpetration was 19.4%. The results of multigroup analyses comparing young adolescents (11-14 years) and older adolescents (15-18 years) differed by age group. For young adolescents, parental maltreatment had a significant effect on bullying perpetration through internet/mobile phone addiction and a sense of community. For older adolescents, there was a direct effect of parental maltreatment on bullying perpetration. However, for older adolescents, there was no significant effect between internet/ mobile phone addiction and bullying perpetration. Conclusion: It is necessary to consider the experiences of peer violence maltreatment, family relationship, internet/mobile phone addiction, a sense of community as key screening factors for bullying perpetration among adolescents.
