While there is evidence to support the use of group dialectical behavior therapy (DBT) in the treatment of binge-eating disorder (BED), treatment is relatively long compared with other evidence-based treatments. This study explored the effectiveness of brief DBT groups for BED, delivered in a routine community setting.
Eighty-four adults with BED entered 10-week DBT group treatment in a community eating disorders service. In total, 12 groups were conducted. Patients completed measures of eating disorder pathology, anxiety, depression, and emotional eating at the start and end of treatment, and at 1-month follow-up. Frequency of weekly binges was recorded.
Outcomes were similar to those of longer versions of DBT, with an attrition rate of 26%, and significant reductions in eating disorder psychopathology and emotional eating by the end of treatment and at follow-up. Over 50% of patients were abstinent from binge eating by Session 4.
Group DBT delivered in a 10-session format is clinically equivalent to longer versions of the same treatment. Future research is required to explore patterns of change and to demonstrate replicability under controlled conditions, but these findings are promising for the efficient delivery of effective treatment and reducing waiting times.
虽然有证据支持在治疗暴食症（BED）时使用团体辩证行为疗法（DBT），但与其他基于证据的治疗方法相比，治疗时间相对较长。本研究探讨了在常规社区环境中进行的简短 DBT 团体治疗对 BED 的有效性。
84 名患有 BED 的成年人参加了社区进食障碍服务中的为期 10 周的 DBT 团体治疗。共进行了 12 组治疗。患者在治疗开始和结束时以及治疗结束后 1 个月时完成了进食障碍病理学、焦虑、抑郁和情绪进食的测量。每周暴食的频率也有记录。
结果与 DBT 的较长版本相似，患者流失率为 26%，并且在治疗结束时和随访时，进食障碍病理学和情绪进食显著减少。超过 50%的患者在第 4 次治疗时已经停止暴食。
在 10 次疗程中提供的团体 DBT 与相同治疗的较长版本在临床效果上是等效的。需要进一步的研究来探索变化模式，并在受控条件下证明可重复性，但这些发现为有效治疗的高效提供了希望，并减少了等待时间。
