There is a wide range of disordered eating behaviors among university students that threaten their mental health. Identifying the factors associated with these behaviors helps prevent it. In this regard, the aim of the present study was to predict disordered eating behavior based on perfectionism and childhood trauma with mediated role of internalized shame. For this purpose, among all students of Islamic Azad universities in Tehran, five universities (Azad North, Center, South, Science and Research and Medical Sciences) were selected and then 400 students, who were selected by available sampling method, were selected. They answered voluntarily to Eating Disordered Behavior Scale (EAT-26), Hill Perfectionism (HPI), Childhood Trauma Scale (CTQ), Internalized Shame (ISS). The results of the path analysis showed that childhood trauma and perfectionism were mediated by shame, predicted eating disorders, and the mediating role of shame in the relationship between childhood trauma, perfectionism, and eating disorders was identified. it seems that people who have been traumatized as children seek compensatory measures such as disordered eating behaviors in order to feel ashamed and return to a positive self-image. Perfectionism can also be exacerbated by having an undesirable body image and feelings of shame, leading to extreme behaviors such as eating disorders, in order to idealize the appearance.
