Comparing Four Psychotherapy Treatments for Adults with Binge Eating Disorder to Find the Most Effective Approach Using Different Cognitive Behavioral Therapy Intensities and Standard Care

What this Trial Is About

Researchers are evaluating the effectiveness of four psychotherapy programs for adults diagnosed with Binge Eating Disorder BED. This randomized clinical trial compares three intensities of Cognitive Behavioral Therapy-Enhanced CBT-E with a manualized treatment as usual, aiming to find which method best reduces binge-eating episodes. The study involves 256 participants, making it the largest of its kind, to provide high-quality evidence on these therapies. Participants are randomly assigned to one of four treatment groups individual CBT-E, group CBT-E, therapist-guided CBT-E self-help, or manualized group-based systemic narrative therapy treatment as usual. Treatments last 21 weeks, with individual CBT-E involving 20 sessions across four stages, group CBT-E delivered in weekly group sessions, guided self-help combining online modules with brief therapist calls, and systemic narrative therapy consisting of weekly long group sessions with meals and psychotherapy. During the trial, participants undergo diagnostic interviews, complete questionnaires on binge eating and psychological well-being, and have their mental health monitored. Assessments occur at baseline, end of treatment, and multiple follow-up points up to five years. Therapists receive training and supervision to ensure treatment quality, and participant safety is carefully monitored. Data collection uses secure electronic systems, and rigorous analysis methods are applied to evaluate treatment outcomes.
