Affect regulation models hypothesize that aversive affective states drive binge-eating behavior, which serves to regulate unpleasant emotions. Research using ecological momentary assessment (EMA) demonstrates that increases in guilt most strongly predict subsequent binge-eating episodes, raising the question: why would individuals with binge-eating pathology engage in a binge-eating episode when they feel guilty? Food craving is a robust predictor of binge eating and is commonly associated with subsequent feelings of guilt. The current study used EMA to test the hypothesis that food craving may promote increased feelings of guilt, which then predict an increased risk of binge eating within a sample of 109 individuals with binge-eating disorder. Multilevel mediation models indicated that increased momentary craving at Time 1 directly predicted a greater likelihood of binge eating at Time 2, and craving also indirectly predicted binge eating at Time 2 through momentary increases in guilt at Time 2. In other words, experiencing food craving at one time point was related to an increased likelihood of binge eating at the next time point, and a portion of this influence was attributable to increasing feelings of guilt. These results challenge simple affect regulation models of binge eating, suggesting that food-related anticipatory reward processes (i.e., craving) may be the primary driver of binge-eating risk and account for the increases in guilt commonly observed prior to binge-eating episodes. Although experimental studies are needed to confirm this possibility, these results suggest the importance of addressing food cravings within interventions for binge-eating disorder.

检查渴望在暴食情绪调节模型中的作用：来自生态瞬时评估研究的证据。

情感调节模型假设厌恶的情感状态会导致暴食行为，从而调节不愉快的情绪。使用生态瞬时评估（EMA）的研究表明，内疚感的增加最能预测随后的暴食事件，这就提出了一个问题：为什么患有暴食病态的人在感到内疚时会参与暴食事件？对食物的渴望是暴食的有力预测因素，并且通常与随后的内疚感相关。目前的研究使用 EMA 来检验一个假设，即对食物的渴望可能会增加负罪感，然后在 109 名暴食症患者的样本中预测暴食的风险会增加。多级中介模型表明，时间 1 时瞬间渴望的增加直接预测时间 2 时暴食的可能性更大，而渴望还通过时间 2 时内疚感的瞬间增加间接预测时间 2 的暴食。换句话说，在时间 2 经历食物渴望一个时间点与下一个时间点暴饮暴食的可能性增加有关，这种影响的一部分可归因于内疚感的增加。这些结果挑战了暴食的简单影响调节模型，表明与食物相关的预期奖励过程（即渴望）可能是暴食风险的主要驱动因素，并解释了暴食发作之前通常观察到的内疚感增加。尽管需要实验研究来证实这种可能性，但这些结果表明在暴食症干预措施中解决食物渴望的重要性。（PsycInfo 数据库记录 (c) 2023 APA，保留所有权利）。
