本研究的目的是使用生态瞬时评估(EMA)来检验热量限制(CR)和暴饮暴食(BE)之间的关系。参与者包括133名患有神经性暴食症(BN)的女性，她们完成了为期2周的EMA方案。Logistic回归分析检验CR是否增加BE发作的概率。结果显示，在限制发生的当天和第二天发生BE的几率都增加了。此外，限制一天和BE均可预测第二天发生BE的可能性，但在发病前两天限制BE不能增加预测BE的额外信息。这些发现支持BN的认知行为疗法(CBT)模型，表明自我报告的饮食限制可以预测随后的BE发作，并且减少治疗中的饮食限制可能会导致暴食症症状的改善。
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.
