Web-based Guided Self-help CBT-E vs Online G-CBT-E for Binge Eating Behavior

Eating disorders with binge eating as the core feature include bulimia nervosa (BN) and binge eating disorder (BED). In recent years, the prevalence rate has increased rapidly, mostly among women, accompanied by emotional problems, physiological complications and increased risks of obesity and depression, which bring great pain to patients. Enhanced Cognitive Behavioral therapy (CBT-E) for eating disorders is an evidence-based and effective first-line psychotherapy for BN and BED. CBT-E is implemented in various forms. In addition to face-to-face therapy, online group CBT-E and guided self-help CBT-E can significantly reduce binge eating in BN and BED patients. However, there are no relevant clinical studies in China. Since 2008, the applicant has carried out CBT treatment and research on eating disorders, translated and published the self-help book "Overcoming Overeating", and accumulated rich clinical research experience. This study intends to establish a set of CBT-E self-help therapy courses suitable for Chinese binge eating patients, and conduct a randomized controlled study of web-based guided self-help CBT-E and online group CBT-E to compare the effectiveness of the treatment modalities in the treatment of binge eating and the feasibility of online guided self-help CBT-E and online group CBT-E in the treatment of binge eating.
