Background Research into psychotherapy for binge-eating disorder (BED) has focused mainly on cognitive behavioural therapies, but efficacy, failure to abstain, and dropout rates continue to be problematic. The experience of negative emotions is among the most accurate predictors for the occurrence of binge eating episodes in BED, suggesting benefits to exploring psychological treatments with a more specific focus on the role of emotion. The present study aimed to explore the feasibility of individual emotion-focused therapy (EFT) as a treatment for BED by examining the outcomes of a pilot randomised wait-list controlled trial. Methods Twenty-one participants were assessed using a variety of feasibility measures relating to recruitment, credibility and expectancy, therapy retention, objective binge episodes and days, and binge eating psychopathology outcomes. The treatment consisted of 12 weekly one-hour sessions of EFT for maladaptive emotions over 3 months. A mixed model approach was utilised with one between effect (group) using a one-way analysis of variance (ANOVA) to test the hypothesis that participants immediately receiving the EFT treatment would demonstrate a greater degree of improvement on outcomes relating to objective binge episodes and days, and binge eating psychopathology, compared to participants on the EFT wait-list; and one within effect (time) using a repeated-measures ANOVA to test the hypothesis that participation in the EFT intervention would result in significant improvements in outcome measures from pre to post-therapy and then maintained at follow-up. Results Recruitment, credibility and expectancy, therapy retention outcomes indicated EFT is a feasible treatment for BED. Further, participants receiving EFT demonstrated a greater degree of improvement in objective binge episodes and days, and binge eating psychopathology compared to EFT wait-list control group participants. When participants in the EFT wait-list control group then received treatment and outcomes data were combined with participants who initially received the treatment, EFT demonstrated significant improvement in objective binge episodes and days, and binge eating psychopathology for the entire sample. Conclusions These findings provide further preliminary evidence for the feasibility of individual EFT for BED and support more extensive randomised control trials to assess efficacy. Trial registration The study was retrospectively registered with the Australian New Zealand Clinical Trials Registry ( ACTRN12620000563965 ) on 14 May 2020.

情绪聚焦疗法治疗暴食症的可行性：一项试点随机等待名单对照试验

背景 暴食症 (BED) 心理治疗的研究主要集中在认知行为疗法上，但疗效、戒酒失败和辍学率仍然存在问题。负面情绪的体验是 BED 暴食发作发生的最准确预测因素之一，这表明探索更具体地关注情绪作用的心理治疗是有益的。本研究旨在通过检查一项试点随机等待名单对照试验的结果，探讨个体情绪聚焦疗法 (EFT) 作为 BED 治疗方法的可行性。方法 使用与招募、可信度和预期、治疗保留、客观暴食事件和天数相关的各种可行性措施对 21 名参与者进行评估，和暴饮暴食的精神病理学结果。治疗包括 12 次每周一小时的 EFT，用于治疗 3 个月内的适应不良情绪。使用一种混合模型方法，使用单向方差分析 (ANOVA) 来测试一个假设，即立即接受 EFT 治疗的参与者将证明与客观暴食事件相关的结果有更大程度的改善，并且与 EFT 候补名单上的参与者相比，暴食精神病理学；一个在效果（时间）内使用重复测量方差分析来检验以下假设：参与 EFT 干预会导致从治疗前到治疗后的结果测量显着改善，然后在随访中保持。结果 招聘、可信度和期望，治疗保留结果表明 EFT 是一种可行的 BED 治疗方法。此外，与 EFT 候补名单对照组参与者相比，接受 EFT 的参与者在客观暴食事件和天数以及暴饮暴食精神病理学方面表现出更大程度的改善。当 EFT 候补名单对照组的参与者随后接受治疗并将结果数据与最初接受治疗的参与者相结合时，EFT 显示出客观暴食事件和天数以及整个样本暴食心理病理学的显着改善。结论 这些发现为 BED 个体 EFT 的可行性提供了进一步的初步证据，并支持更广泛的随机对照试验来评估疗效。
