Treatment Results of Anorexia Nervosa and Bulimia Nervosa in a Residential Treatment Program.

Data on the effectiveness of residential treatment for patients with anorexia nervosa (AN) and bulimia nervosa (BN) are limited. We analyzed patient survey results at admission and discharge from Monte Nido Residential Treatment Program. Of 287 consecutive admissions, 80% (231) 'graduated' (completed ≥ 30 days of treatment), and of these (all of whom gave consent), only patients with AN (N = 120) or BN (N = 95) were included (215 of 231, 93%) in this study. Analyses included a comparison of admission vs. discharge variables (paired t-tests) for each diagnosis. At each assessment, graduates completed the Eating Disorders Inventory-2 (EDI-2), the Beck Depression Inventory (BDI), and a structured eating disorder assessment questionnaire. For patients with AN, there were statistically significant improvements in mean BMI. In addition, for both AN and BN patients, there were statistically significant improvements in BDI scores, all 11 EDI-2 subscales, and frequencies of bingeing, vomiting, laxative abuse, chewing and spitting, stimulant abuse, and restricting behavior. The great majority of patients completing treatment showed significant improvement at discharge from intensive residential treatment. [ABSTRACT FROM AUTHOR]
