Affect regulation models of eating disorder behavior, which predict worsening of affect prior to binge-eating episodes and improvement in affect following such episodes, have received support in anorexia nervosa and bulimia nervosa. However, limited work has examined the trajectories of affect surrounding binge eating in binge-eating disorder (BED). In the current study, ecological momentary assessment data from 112 men and women with BED were used to examine the trajectories of positive affect (PA), negative affect (NA), guilt, fear, hostility, and sadness relative to binge-eating episodes. Prior to binge episodes, PA significantly decreased, whereas NA and guilt significantly increased. Following binge episodes, levels of NA and guilt significantly decreased and PA stabilized. Overall, results indicate improvements in affect following binge-eating episodes, suggesting that binge eating may function to alleviate unpleasant emotional experiences among individuals with BED, which is consistent with affect regulation models of eating pathology. Because improvements in negative affect were primarily driven by change in guilt, findings also highlight the relative importance of understanding the relationship between guilt and binge-eating behavior within this population.

情感在维持暴饮暴食症中的作用：来自生态瞬时评估研究的证据。

饮食失调行为的情感调节模型可预测神经性厌食症和神经性贪食症，该模型预测暴饮暴食发作前的情绪恶化以及此类发作后的情绪改善。然而，有限的工作已经研究了暴饮暴食症（BED）中暴饮暴食周围的影响轨迹。在当前的研究中，使用来自112名患有BED的男性和女性的生态瞬时评估数据来检查相对于暴饮暴食发作的正面影响（PA），负面影响（NA），内gui，恐惧，敌意和悲伤的轨迹。暴饮暴食之前，PA显着降低，而NA和内gui感显着增加。暴饮暴食后，NA和内的水平显着降低，PA稳定。总体，结果表明，暴饮暴食后发作对情绪的影响有所改善，表明暴饮暴食可以缓解BED患者的不愉快的情绪体验，这与饮食病理的影响调节模型一致。由于消极情绪的改善主要是由内感的变化所致，因此研究结果也凸显了了解这一人群内感和暴饮暴食行为之间关系的相对重要性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。研究结果还强调了了解这一人群内within和暴饮暴食行为之间的关系的相对重要性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。研究结果还强调了了解这一人群内和暴饮暴食行为之间的关系的相对重要性。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
