本研究的目的是测试两个变量的影响后暴饮暴食的负面情绪的合并样本的妇女神经性厌食症（AN; n = 47）和神经性贪食症（BN; n = 121）。参与者完成了为期两周的生态瞬时评估协议，在此期间，他们提供了多个整体负面影响和内疚的日常评级，并报告了饮食失调行为，包括暴饮暴食和自我诱发的呕吐。结果表明，在暴饮暴食事件发生后的一个小时内，总体负面情绪和内疚感都表现出统计学上的显著下降。内疚感的减少，但不是整体的负面影响，是由饮食失调诊断和自我诱发呕吐的倾向所缓和的。具体来说，BN患者的内疚感比AN患者减少得更多，而通常不进行自我诱导呕吐的人比通常进行自我诱导呕吐的人内疚感减少得更多。这项研究扩展了现有的文献对负面影响和饮食失调行为之间的关系，表明内疚作为一个潜在的相关方面的负面影响，在维持暴食。此外，研究结果表明，两个个体差异，饮食失调诊断和自我诱发呕吐，可能会影响暴食事件后的内疚轨迹。(C)2012爱思唯尔有限公司版权所有。
The purpose of this study was to test the impact of two variables on post-binge eating negative emotion in a combined sample of women with anorexia nervosa (AN; n = 47) and bulimia nervosa (BN; n = 121). Participants completed two weeks of an ecological momentary assessment protocol during which they provided multiple daily ratings of overall negative affect and guilt and reported eating disorder behaviors including binge eating and self-induced vomiting. The results indicate that both overall negative affect and guilt exhibited a statistically significantly decrease in the hour immediately following binge eating episodes. The decrease in guilt, but not overall negative affect, was moderated by eating disorder diagnosis and the tendency to engage in self-induced vomiting. Specifically, individuals with BN reported a greater reduction in guilt than those with AN, and individuals who did not typically engage in self-induced vomiting reported more decreases in guilt than those who typically engaged in self-induced vomiting. This study extends the existing literature on the relationship between negative affect and eating disorder behaviors, suggesting guilt as a potentially relevant facet of negative affect in the maintenance of binge eating. In addition, the findings indicate that two individual differences, eating disorder diagnosis and self-induced vomiting, may influence the trajectory of guilt following binge eating episodes.
