This research investigated the influence of child characteristics, parenting behaviours and teacher-child relationships in order to ascertain peer victimization among 297 Korean preschool children. Peer victimization, child social behaviours and teacher-child relationships were assessed through teacher reports. Parents completed parenting behaviour questionnaires. Results suggested independent contributions from neglectful/rejected parenting, aggression, withdrawal and conflict in teacher-child relationships. Moreover, parental neglect/rejection moderated the association between aggression and peer victimization. Implications of the results for intervention initiatives are discussed.
