Self-oriented perfectionism in eating disorders

OBJECTIVE: To assess perfectionism dimensions in eating disorders in comparison with other psychiatric disorders and subjects from the general population. METHOD: The Child and Adolescent Perfectionism Scale (CAPS), the Eating Disorders Inventory (EDI-2), and the Eating Attitudes Test (EAT) were administered to a group of 108 female eating-disordered patients (75 anorexia nervosa and 33 bulimia nervosa), to a group of 86 female psychiatric patients with anxiety (N = 32), depressive (N = 38), or adaptive disorders (N = 16), and to 213 healthy female participants. RESULTS: Both bulimic and anorexic patients scored higher on Self-Oriented Perfectionism (p < 0.001) than the other two groups but not on Socially-Prescribed Perfectionism (p = 0.054). Among patients with eating disorder, 17.6% obtained a score two standard deviations higher than the mean in the healthy comparison group on self-oriented perfectionism; this percentage was significantly higher than in the other two groups. The percentage of eating disorder patients with high socially-prescribed perfectionism was similar to that found in other psychiatric disorders. Moreover, self-oriented perfectionism was a predictor of an eating disorder. CONCLUSION: Self-oriented perfectionism is more specific to eating disorders than to depressive or anxiety disorders.
