This report examined baseline affective response to binge eating as a predictor of binge-eating disorder (BED) treatment outcome. Baseline affective response was defined as: (1) 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 (2) post-binge eating slope of PA or NA across seven-days of ecological momentary assessment (EMA). Adults with BED completed Integrative Cognitive-Affective Therapy (ICAT-BED) or cognitive behavioral therapy guided self-help (CBTgsh). Individuals with greater net increases in PA (AUC) following binge eating at baseline exhibited better treatment response in ICAT-BED at end-of-treatment and follow-up. NA affective response was only significant at end-of-treatment; individuals with less rapid post-binge improvements in NA (slope) did better in ICAT-BED, while individuals with lower net improvements in NA (AUC) did better in CBTgsh. Affective response to binge eating may be a marker of BED treatment response.
本报告研究了对暴饮暴食的基线情感反应作为暴饮暴食障碍（BED）治疗结果的预测指标。基线情感反应定义为：（1）每个个体在暴饮暴食发作前后积极情感（PA）或消极情感（NA）的平均净变化（即曲线下面积[AUC]），以及（2）在为期七天的生态瞬时评估（EMA）中暴饮暴食后PA或NA的斜率。患有BED的成年人完成了综合认知情感疗法（ICAT-BED）或认知行为疗法指导自助（CBTgsh）。在基线时暴饮暴食后PA净增加量（AUC）更大的个体，在治疗结束时和随访时的ICAT-BED治疗中表现出更好的治疗反应。NA情感反应仅在治疗结束时显著；暴饮暴食后NA改善速度较慢（斜率）的个体在ICAT-BED中表现更好，而NA净改善量较低（AUC）的个体在CBTgsh中表现更好。对暴饮暴食的情感反应可能是BED治疗反应的一个指标。
