This study examined self-discrepancy, a construct of theoretical relevance to eating disorder (ED) psychopathology, across different types of EDs. Individuals with anorexia nervosa (AN; n = 112), bulimia nervosa (BN; n = 72), and binge eating disorder (BED; n = 199) completed semi-structured interviews assessing specific types of self-discrepancies. Results revealed that actual:ideal (A:I) discrepancy was positively associated with AN, actual:ought (A:O) discrepancy was positively associated with BN and BED, and self-discrepancies did not differentiate BN from BED. Across diagnoses, A:O discrepancy was positively associated with severity of purging, binge eating, and global ED psychopathology. Further, there were significant interactions between diagnosis and A:O discrepancy for global ED psychopathology and between diagnosis and A:I discrepancy for binge eating and driven exercise. These results support the importance of self-discrepancy as a potential causal and maintenance variable in EDs that differentiates among different types of EDs and symptom severity.
