DEPRESSION IN ANOREXIA-NERVOSA AND BULIMIA-NERVOSA - DISCRIMINATING DEPRESSIVE SYMPTOMS AND EPISODES

In a clinical sample of 198 female patients with anorexia nervosa (N = 83) and bulimia nervosa (N = 115), 43% met criteria for major depress ion using the Structured Clinical Interview for DSM III-R. This group had a mean score of 30.9 +/- 8.7 on the Beck Depression Inventory (BDI ) which was significantly higher than the BDI mean score of 20.5 +/- 8 .9 among the remainder of the sample (p<0.0001). A score of 26 yielded the highest levels of sensitivity and specificity, while five items f rom the BDI (loss of satisfaction, discouragement, weight loss, suicid al ideation and decision-making) correctly classified approximately 80 % of subjects into ''depression-positive'' or ''depression-negative'' categories. Detection of co-morbid depression in patients with eating disorders may have practical implications for treatment.
