In this report, we examined baseline affective response to binge eating as a predictor of binge-eating disorder (BED) treatment outcome. Baseline affective response was defined as (a) each individual’s average net change (i.e., area under the curve [AUC]) of positive affect (PA) or negative affect (NA) before and after binge-eating episodes and (b) slope of PA or NA after binge eating across 7 days of ecological momentary assessment. Adults with BED completed integrative cognitive-affective therapy (ICAT-BED) or cognitive behavioral therapy-guided self-help (CBT-gsh). Individuals with greater net increases in PA (AUC) after binge eating at baseline exhibited better treatment response in ICAT-BED at end of treatment and follow-up. NA affective response was significant only at end of treatment; individuals with less rapid postbinge improvements in NA (slope) did better in ICAT-BED, whereas individuals with lower net improvements in NA (AUC) did better in CBT-gsh. Affective response to binge eating may be a marker of BED treatment response.

在本报告中，我们检查了对暴食的基线情感反应作为暴食症 (BED) 治疗结果的预测因子。基线情感反应被定义为（a）每个人在暴饮暴食之前和之后的积极影响（PA）或消极影响（NA）的平均净变化（即曲线下面积[AUC]）和（b）斜率在 7 天的生态瞬时评估中暴饮暴食后的 PA 或 NA。患有 BED 的成年人完成了综合认知情感疗法 (ICAT-BED) 或认知行为疗法引导的自助 (CBT-gsh)。基线暴食后 PA (AUC) 净增加较大的个体在治疗结束和随访时在 ICAT-BED 中表现出更好的治疗反应。NA 情感反应仅在治疗结束时显着；NA（斜率）改善较慢的个体在 ICAT-BED 中表现更好，而 NA（AUC）净改善较低的个体在 CBT-gsh 中表现更好。对暴食的情感反应可能是 BED 治疗反应的标志。
