Notes. BDI-II, Beck Depression Inventory—2; BMI, body mass index; EDE-Q, Eating Disorders Examination Questionnaire; Y-BOCS-SR = Yale-Brown Obsessive-Compulsive Scale—Self-Report.
Proportion of patients with a Y-BOCS-SR change of at least 25% at discharge: anorexia nervosa, 16 of 23 (70%); bulimia nervosa, 14 of 14 (100%); eating disorder-NOS, 15 of 19 (79%).
Post-hoc pairwise comparisons for change in Y-BOCS-SR: anorexia nervosa < bulimia nervosa (p = 0.012). Other pairwise comparisons did not reach significance.
Post-hoc pairwise comparisons for change in EDE-Q: anorexia nervosa < bulimia nervosa (p = 0.013). Other pairwise comparisons did not reach significance.
Post-hoc pairwise comparisons for change in BMI: anorexia nervosa > bulimia nervosa (p = 0.008). Other pairwise comparisons did not reach significance.
Post-hoc pairwise comparisons for change in BDI-II: anorexia nervosa < bulimia nervosa (p = 0.002) and anorexia nervosa < eating disorder-NOS (p = 0.029). Other pairwise comparisons did not reach significance.
