Childhood trauma and eating disorder risk among young adult females: The mediating role of mentalization

Eating disorders (EDs) are particularly prevalent among young adult females. Previous research has shown that childhood trauma and reduced mentalizing abilities are involved in ED symptoms. The current study was aimed at testing the mediating effects of failures in mentalizing on the relationship between childhood trauma and ED risk among young adult females. The sample consisted of 409 Caucasian young adult females, aged between 18 and 30 years old (M = 23.45, SD = 2.76). The reported mean body mass index was within the normal range (M = 22.62; SD = 4.35). Self-report instruments were administered to assess the variables of interest. Structural equation modeling revealed that childhood trauma predicted increased failures in mentalizing (β =.36) and ED risk (β =.30), that failures in mentalizing predicted an increased ED risk (β =.35), and that the positive association between childhood trauma and ED risk was partially mediated by failures in mentalizing (indirect effect: β =.13). These findings suggest that ED symptoms might result from unprocessed and painful feelings embedded in child abuse and neglect. Clinical interventions focused at improving mentalizing abilities might reduce the ED risk among young adult females who have been exposed to childhood trauma.
