Video-based Guided Self Help Dialectical Behavior Therapy for Binge Eating Disorder

Summary

Dialectical Behavior Therapy (DBT) is an effective treatment for eating disorders, showing promising remission rates for Binge Eating Disorder (BED) in both standard and guided self-help formats. Traditional guided self-help models typically combine weekly chapter readings with a limited number of brief therapist meetings. However, the requirement of weekly book readings can be particularly challenging for individuals with BED, who often exhibit impulsive personality traits, psychiatric comorbidities, and weight-related health problems.

This study was developed to test a version of guided self-help DBT-BED delivered through video lessons instead of text. This randomized clinical trial will be conducted at the Eating Disorders Program of the Institute of Psychiatry, Hospital das Clínicas, Faculty of Medicine, University of São Paulo (AMBULIM IPq HC FMUSP), Brazil. Eighty adults with BED will be randomized to either an experimental group (weekly video lessons) or a control group (weekly text-based readings).

Both groups will undergo a 13-week intervention, including six brief 30-minute online guidance sessions with a psychologist. The primary outcome will be full remission from binge eating episodes at the end of treatment and at the 3-month follow-up. Secondary outcomes will include changes in eating disorder psychopathology, emotion regulation, quality of life, self-esteem, and dropout rates. Statistical analyses will follow the intention-to-treat principle.

Interventions

BEHAVIORAL

Experimental: Video-based DBTgsh for BED

This is a guided self-help behavioral intervention based on Dialectical Behavior Therapy for Binge Eating Disorder (DBT-BED), delivered through weekly pre-recorded video lessons over 13 weeks. The intervention covers three core DBT skill modules-mindfulness, emotion regulation, and distress tolerance-and is supported by six brief 30-minute individual online guidance sessions with a psychologist to enhance adherence, clarify content, and support skill application.

BEHAVIORAL

Traditional DBTgsh for BED (text-based model)

This is a guided self-help behavioral intervention based on Dialectical Behavior Therapy for Binge Eating Disorder (DBT-BED), delivered through weekly chapter readings from a structured manual over 13 weeks. The intervention covers the same three core DBT skill modules-mindfulness, emotion regulation, and distress tolerance-and is supported by six brief 30-minute individual online guidance sessions with a psychologist to enhance adherence, clarify content, and support skill application.
