A growing body of literature is demonstrating associations between childhood maltreatment and bullying involvement at school. In this literature review, four potential mediators (explanatory) and three potential moderators (mitigates or exacerbates) of the association between childhood maltreatment and school bullying are proposed. Mediators include emotional dysregulation, depression, anger, and social skills deficits. Moderators reviewed include quality of parent-child relationships, peer relationships, and teacher relationships. Although there might be insurmountable challenges to addressing child maltreatment in primary or universal school-based prevention programs, it is possible to intervene to improve these potentially mediating and moderating factors.
