Comorbid depressive symptoms and self-esteem improve after either cognitive-behavioural therapy or family-based treatment for adolescent bulimia nervosa.

This study examined the effect of family-based treatment for bulimia nervosa (FBT-BN) and cognitive behavioral therapy for adolescents (CBT-A) on depressive symptoms and self-esteem in adolescents with BN. Data were collected from 110 adolescents, ages 12-18, who met Diagnostic and Statistical Manual of Mental Disorders-Fourth Edition, text revision criteria for BN or partial BN. Participants were randomly assigned to FBT-BN or CBT-A and completed measures of depressive symptoms and self-esteem before and after treatment and at 6- and 12-month follow-up assessments. Depressive symptoms and self-esteem significantly improved in both treatments, and neither treatment appeared superior on these clinical outcomes. Parents often worry whether FBT-BN addresses comorbid depressive symptoms and low self-esteem. Our findings address this concern, as they demonstrate that FBT-BN does not differ from CBT-A in improving depressive symptoms and self-esteem, and both treatments result in symptom improvement. These findings can help clinicians guide families to choose a treatment that addresses BN and depressive symptoms and low self-esteem.
