The Effectiveness of Online Group Dialectical Behavioral Therapy on Bulimia Nervosa
Sponsor: Shanghai Mental Health Center
Summary
Bulimia Nervosa (BN) is a kind of chronic refractory mental disorder with high prevalence and relapse rate, which would cause serious damage to physical and mental health. Dialectical Behavioral Therapy (DBT) is an internationally effective and evidence-based therapy for BN patients. Previous studies have found that DBT group therapy can significantly improve the core symptoms of BN patients. Our research group has conducted DBT group therapy for BN, and found that after 12 weeks of treatment, the frequencies of binge eating and purging behavior of BN patients were significantly reduced. However, with the high cost of ground-based group therapy and low coverage, it is difficult to promote the G-DBT(Group Dialectical Behavioral Therapy) for BN, considering the shortage of mental health resource in China. Besides, videoconferencing-based psychotherapy has gradually emerged in recent years. However, there is still a lack of clinical studies on the videoconferencing-based G-DBT for BN at home and abroad to confirm its efficacy and feasibility. Therefore, this study intends to use a randomized controlled study by randomly allocating BN patients into videoconferencing-based G-DBT group and traditional G-DBT group for 12 weeks. By comparing the changes of core symptoms and psychological characteristics of BN patients before and after treatment, this study aims to illustrate the efficacy and feasibility of videoconferencing-based G-DBT is no less than traditional G-DBT.
