Comprehensive models, targeting the development of eating disorders (EDs) in males, often employ a sociocultural perspective and empathize the importance of body dissatisfaction (BD). To further illuminate psychological factors contributing to the development of ED pathology, we propose a mediator model of disturbed eating and compensatory behavior (DECB) for men. This model suggests that emotion dysregulation and the susceptibility to body-related cognitive distortions (thought-shape fusion, TSF) mediate the relationship between BD and DECB. Based on data from a cross-sectional online-survey we tested our model in a non-clinical community sample of young men (N=123,18-37 years). We found a significant positive association between BD and DECB, accounting for participant's body mass index (BMI), age and depressive symptoms. While TSF partially mediated the relationship between BD and DECB, we did not detect a corresponding effect for emotion dysregulation. Based on our findings, we concluded that TSF, which describes specific distorted cognitions with respect to one's own body triggered by fattening/forbidden food, contributes to the pathological eating- and body-related behavior in men who are dissatisfied with their body. We suggest that TSF should be included in etiological models as a relevant aspect of cognitive information processing with emotional and behavioral consequences. (C) 2016 Elsevier Ireland Ltd.
