Comparing Enhanced Cognitive-behavior Therapy and Family-based Treatment for Adolescents With an Eating Disorder

Summary

The goal of this randomized controlled clinical trial is to compare the efficacy of outpatient family-based treatment versus enhanced cognitive behavior therapy for children and adolescents with eating disorders.

Because of insufficient recruitment, the study design was modified on December 1st, 2025, to a partially randomized preference design.

The main aim is to determine if enhanced cognitive behavior therapy has a similar efficacy as family-based treatment among children and adolescents with eating disorders receiving treatment in an outpatient setting. The main outcome is improvement in eating disorders psychopathology at the end of treatment.
