The present study sought to examine the independent, hierarchical, and integrative models of multiple attachment relationships in a sample of Greek-Cypriots in middle adolescence and to test the distinct and interactive effects of these relationships on bullying involvement. A sample of Greek-Cypriot adolescents (N?=?406, 55.4% females, M[subscript age]?=?16.01, SD?=?0.82) completed the Greek forms of the Revised Olweus Bully-Victim Questionnaire (BVQ-R), the Inventory of Parental and Peer Attachment (IPPA), and the Questionnaire on Teacher Interaction (QTI). Path models were used to test for the effect of multiple attachment relationships on bullying and victimization, using AMOS 24.0.The integrative model of multiple attachment relationships was supported and found to have significant effects on bullying involvement. The effect of the quality of the mother-adolescent relationship on bullying involvement was fully mediated by the quality of the attachment relationships with peers and the interpersonal relationship with teachers. The quality of adolescents' relationship with teachers affected their interactions with peers, and not the opposite, though both continued to have distinct effects on bullying involvement.
