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.
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.
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.
These findings provide further preliminary evidence for the feasibility of individual EFT for BED and support more extensive randomised control trials to assess efficacy.

针对暴饮暴食症（BED）的心理治疗研究主要集中在认知行为疗法上，但疗效、无法戒除以及脱落率仍然是问题所在。负面情绪体验是BED中暴饮暴食发作最准确的预测因素之一，这表明探索更具体关注情绪作用的心理治疗方法可能有益。本研究旨在通过考察一项试点随机等待列表对照试验的结果，探讨个体情绪聚焦疗法（EFT）作为BED治疗方法的可行性。
使用了多种与招募、可信度和期望、治疗保留率、客观暴饮暴食发作次数和天数以及暴饮暴食心理病理学结果相关的可行性指标对21名参与者进行评估。治疗包括在3个月内每周进行12次、每次1小时的EFT，以处理适应不良情绪。采用混合模型方法，一个组间效应（组）使用单因素方差分析（ANOVA）来检验以下假设：与EFT等待列表上的参与者相比，立即接受EFT治疗的参与者在客观暴饮暴食发作次数和天数以及暴饮暴食心理病理学相关结果上会有更大程度的改善；一个组内效应（时间）使用重复测量ANOVA来检验以下假设：参与EFT干预将导致从治疗前到治疗后结果测量有显著改善，并在随访时维持。
招募、可信度和期望、治疗保留率结果表明EFT是BED的一种可行治疗方法。此外，与EFT等待列表对照组参与者相比，接受EFT治疗的参与者在客观暴饮暴食发作次数和天数以及暴饮暴食心理病理学方面有更大程度的改善。当EFT等待列表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在整个样本的客观暴饮暴食发作次数和天数以及暴饮暴食心理病理学方面显示出显著改善。
这些发现为个体EFT治疗BED的可行性提供了进一步的初步证据，并支持进行更广泛的随机对照试验以评估疗效。
