Abstract

The principal aim of the study was to investigate the relationship between trust in attachment relationships to parents and peers, and eating disorders by analyzing the possible moderating effect of interpersonal perfectionism and insecurity on this relation. The sample of this research consists of 699 students (478 females, 221 males), aged between 15 and 18 years, to whom three questionnaires were administered: Eating Attitudes Test (EAT-26), Eating Disorder Inventory (EDI-3), Inventory of Parent (IPPA-G) and Peer Attachment (IPPA-P). The results showed that, as for girls, perfectionism seems moderats the relationship between low trust in the relationship of attachment to parents and eating disorders. As for males, however, interpersonal insecurity seems to have a moderating effect between low trust in their attachment to peers and the development of dysfunctional eating behavior.
