Body Dysmorphic Disorder (BDD) is a serious psychiatric condition that has long been identified as an important risk factor for the development of eating-related difficulties. However, little is known about the mechanisms that might explain this association. Therefore, the current study aimed to explore the link between body dysmorphic symptomatology and disordered eating, and test whether this relationship is mediated by higher levels of shame and self-criticism. This cross-sectional study included 291 women from the community, aged between 18 and 62 years old, who completed self-report measures. Path analysis revealed that BDD symptomatology has not only a direct effect on disordered eating, but also an indirect effect, mediated by shame and self-criticism. The path model revealed a very good fit, accounting for 38% and 31% of internal and external shames' variances, respectively, for 69% of self-criticism variance, and 58% of the variance of disordered eating. These findings seem to suggest that in women with BDD symptomatology, disordered eating may emerge as a compensatory strategy to cope with general feelings of inferiority/defectiveness, particularly in the presence of shame experiences and self-critical attitudes/behaviours. Moreover, this study emphasizes the importance to invest in innovative treatment and prevention approaches for BDD that specifically target shame and self-criticism, such as compassion-based therapies. LEVEL OF EVIDENCE: IV, cross-sectional study.
