暴饮暴食的情绪调节模型，假设患者暴饮暴食以减少负面情绪（NA），已经得到了横断面和实验室研究的支持。生态瞬时评估（EMA）涉及瞬时评级和随着时间的推移重复评估，非常适合识别暴饮暴食的时间前因和后果。这篇荟萃分析综述包括EMA对情绪和暴食的研究。电子数据库和手动检索产生了36项EMA研究，N = 968例受试者（89%为白人女性）。荟萃分析使用受试者内标准化平均增益效应量（ES）检查了暴饮暴食前后情绪的变化。结果支持更大的NA前暴饮暴食相对于平均影响（ES = 0.63）和影响之前定期进食（ES = 0.68）。然而，NA在暴食发作后进一步增加（ES = 0.50）。初步研究结果表明，NA在神经性贪食症（ES =-0.46）的净化后下降。调节因素包括诊断（与神经性贪食症相比，暴饮暴食症患者暴饮暴食前NA的升高显著更大）和暴饮暴食定义（与非专业暴饮暴食定义相比，DSM定义的暴饮暴食前NA的升高显著小于正常饮食事件）。总体而言，结果不支持暴食的影响调节模型和挑战减少NA作为暴食的维持因素。然而，这篇文献的局限性包括NA的一维分析和不充分的检查，在暴饮暴食的影响，暴饮暴食可能只调节特定方面的影响，或可能减少NA只在发作期间。
The affect regulation model of binge eating, which posits that patients binge eat to reduce negative affect (NA), has received support from cross-sectional and laboratory-based studies. Ecological momentary assessment (EMA) involves momentary ratings and repeated assessments over time and is ideally suited to identify temporal antecedents and consequences of binge eating. This meta-analytic review includes EMA studies of affect and binge eating. Electronic database and manual searches produced 36 EMA studies with N = 968 participants (89% Caucasian women). Meta-analyses examined changes in affect before and after binge eating using within-subjects standardized mean gain effect sizes (ES). Results supported greater NA preceding binge eating relative to average affect (ES = .63) and affect before regular eating (ES = .68). However, NA increased further following binge episodes (ES = .50). Preliminary findings suggested that NA decreased following purging in Bulimia Nervosa (ES = −.46). Moderators included diagnosis (with significantly greater elevations of NA prior to bingeing in Binge Eating Disorder compared to Bulimia Nervosa) and binge definition (with significantly smaller elevations of NA before binge versus regular eating episodes for the DSM definition compared to lay definitions of binge eating). Overall, results fail to support the affect regulation model of binge eating and challenge reductions in NA as a maintenance factor for binge eating. However, limitations of this literature include unidimensional analyses of NA and inadequate examination of affect during binge eating as binge eating may regulate only specific facets of affect or may reduce NA only during the episode.
