OBJECTIVE This study examined patients with binge-eating disorder (BED) subtyped by dietary restraint (DR) and the negative affect (NA) dimension of depression, anxiety, hostility, and self-esteem, comparing clinical features and outcome of evidence-based psychological treatments. It was hypothesized that individuals with DR and high NA (DR-HNA) would have lower functioning and poorer immediate and long-term BED treatment outcomes compared to those with DR and low NA (DR-LNA). METHOD Cluster analysis was conducted (n = 159) as a secondary analysis of data from a randomized group cognitive-behavioral therapy and interpersonal psychotherapy trial of women and men with BED. RESULTS At pretreatment, participants with DR-HNA were higher in eating disorder and general psychopathology, emotional eating, and poor social adjustment. At post-treatment, differences in binge days between cluster groups were small and statistically nonsignificant, and differences in rates of binge-eating abstinence were only marginally significant. However, by 1-year follow-up, patients with DR-HNA had a greater increase in binge days, less abstinence from binge eating, a higher risk for relapse, and were significantly less likely to be in BED remission than those with DR-LNA. CONCLUSIONS DR-HNA served as a predictor of poorer maintenance of BED therapeutic improvement. Future directions to better sustain outcomes among patients with DR-HNA include developing a brief measure to assess for the full construct of NA prior to and throughout treatment, enhancing BED interventions by focusing more on NA, and augmenting treatment dose.

通过饮食限制和负面影响对暴食症患者进行亚型分类：特征和治疗结果。


目的 本研究检查了饮食限制（DR）亚型的暴食症（BED）患者以及抑郁、焦虑、敌意和自尊的负面影响（NA）维度，比较了循证心理治疗的临床特征和结果。治疗。据推测，与 DR 和低 NA (DR-LNA) 患者相比，DR 和高 NA (DR-HNA) 患者的功能较低，近期和长期 BED 治疗结果较差。方法 对患有暴食症的女性和男性进行随机分组认知行为治疗和人际心理治疗试验的数据进行聚类分析（n = 159）作为二次分析。结果 在治疗前，患有 DR-HNA 的参与者饮食失调、一般精神病理学、情绪化饮食和社会适应能力较差。治疗后，集群组之间的暴食天数差异很小，并且在统计学上不显着，并且暴食戒断率的差异也仅有轻微显着性。然而，到 1 年随访时，与 DR-HNA 患者相比，DR-HNA 患者暴食天数增加较多，暴食节制较少，复发风险较高，并且 BED 缓解的可能性显着降低。低噪声放大器。结论 DR-HNA 可作为 BED 治疗改善维持较差的预测因子。未来更好地维持 DR-HNA 患者预后的方向包括制定一项简短的措施来评估治疗前和整个治疗过程中 NA 的完整结构，通过更多地关注 NA 来加强 BED 干预，以及增加治疗剂量。 （PsycInfo 数据库记录 (c) 2022 APA，保留所有权利）。
