The purpose of this study was to examine the relationship between caloric restriction (CR) and binge eating (BE) using ecological momentary assessment (EMA). Participants included 133 women with bulimia nervosa (BN) who completed an EMA protocol for 2 weeks. Logistic regression analyses tested whether CR increased the probability of BE episodes. The results revealed that the odds of BE increased on the day that restriction occurred as well as on the following day. In addition, both restriction and BE on one day predicted the likelihood of BE the subsequent day, but restriction for two days prior to the episode failed to add additional information for predicting BE. These findings support the cognitive behavioral therapy (CBT) model of BN, suggesting that self-reported dietary restriction is predictive of subsequent BE episodes, and that reducing dietary restriction in treatment may lead to improvements in bulimic symptoms.
本研究旨在使用生态瞬时评估 (EMA) 研究热量限制 (CR) 与暴食 (BE) 之间的关系。参与者包括 133 名患有神经性贪食症 (BN) 的女性，她们完成了为期 2 周的 EMA 方案。逻辑回归分析测试了 CR 是否会增加 BE 发作的可能性。结果表明，限制发生当天和次日 BE 的可能性增加。此外，一天内的限制和 BE 都预测了第二天发生 BE 的可能性，但在发作前两天的限制并不能为预测 BE 提供额外的信息。这些发现支持 BN 的认知行为治疗 (CBT) 模型，表明自我报告的饮食限制是随后 BE 发作的预测因素，并且在治疗中减少饮食限制可能会导致贪食症状的改善。
