Long-term follow-up of a randomized controlled trial comparing systemic family therapy (FT-S) added to treatment as usual (TAU) with TAU alone in adolescents with anorexia nervosa.

Randomized controlled trials showed the efficacy of family therapy for anorexia nervosa during adolescence, but studies examining its long-term beneficial effect are still needed. This article presents the results of a 54-month post-randomization follow-up of a previously reported randomized controlled trial that compared two post-hospitalization outpatient treatment programs: Treatment As Usual alone versus Systemic Family Therapy added to Treatment As Usual.
