A comparison of eating disorders and body dysmorphic disorder on body image and psychological adjustment.

Eating and body dysmorphic disorders are two diagnoses with body image disturbance as a central feature. No empirical study of the similarity of these disorders or any controlled study of body dysmorphic disorder were available. The present study compared 45 women with anorexia or bulimia nervosa to 51 men and women with body dysmorphic disorder (BDD) and 50 nonclinical controls. The eating disorder patients were mainly preoccupied with weight and body shape. BDD subjects had more diverse physical complaints and reported more negative self-evaluation and avoidance due to appearance. However, the two groups showed equally severe body image symptoms overall, and were clearly abnormal compared with controls. Both types of patients had negative self-esteem, but eating disorder patients had more widespread psychological symptoms. In conclusion, the disorders are comparable on psychological measures. Explanations of the minor differences and questions for future research on the relation between eating and body dysmorphic disorders are presented.
