Few empirical studies have examined the potential role of affect in dysregulated eating. The authors hypothesized that distress tolerance would predict EDI-Bulimia, even when controlling for several covariates, including depressive and anxiety symptoms, and all four subscales of the UPPS Impulsive Behavior Scale. Additionally, the authors predicted low levels of distress tolerance would interact with high levels of urgency to predict EDI-Bulimia. Finally, the authors predicted that distress tolerance would mediate the previously reported relationship between anxiety sensitivity and EDI-Bulimia.
A sample of undergraduates (N = 200) filled out a series of questionnaires pertaining to the variables of interest, including the Eating Disorder Inventory, UPPS Impulsive Behavior Scale, Distress Tolerance Scale, and Anxiety Sensitivity Index.
All three hypotheses were supported by the data.
Authors suggest that deficits in distress tolerance might play a significant role in the etiology and maintenance of bulimic symptoms.
很少有实证研究探讨情感在饮食失调中的潜在作用。作者假设，即使在控制了包括抑郁和焦虑症状以及UPPS冲动行为量表的所有四个分量表在内的几个协变量之后，痛苦耐受力仍能预测《饮食失调问卷-暴食症量表》（EDI-Bulimia）得分。此外，作者预测，低水平的痛苦耐受力会与高水平的紧迫感相互作用，从而预测EDI-Bulimia得分。最后，作者预测痛苦耐受力将介导先前报道的焦虑敏感性与EDI-Bulimia之间的关系。
一组本科生样本（N = 200）填写了一系列与感兴趣的变量相关的问卷，包括《饮食失调问卷》、UPPS冲动行为量表、痛苦耐受力量表和焦虑敏感性指数。
所有三个假设均得到数据支持。
作者认为，痛苦耐受力不足可能在暴食症状的病因和维持中起重要作用。
