目的：本研究考察了人际压力源对有（N = 20）和无（N = 20）显著暴食症状的女性后续卡路里摄入的影响。方法：受试者根据实验条件（有压力和无压力）参加两个不同的实验阶段，在实验任务前后完成情绪和焦虑的自我报告测量，并在每个实验阶段后提供一系列零食。结果：与假设相反，有暴食症状的女性在面临压力时并没有增加她们的摄入量。然而，每种常量营养素的摄入结果表明，在压力源之后，暴食症和对照组的女性都增加了碳水化合物的摄入。因此，压力与所有受试者的碳水化合物消耗量增加有关，但对有暴食症状的女性的消耗量没有差异。结论：可能是有暴食症状的女性在面对压力时对饮食的易感性没有差异，或者是目前的实验室模式无法检测出压力源后饮食的差异。
Objective: This study examined the effects of an interpersonal stressor on subsequent calorie intake in females with (N = 20) and without (N = 20) significant bulimic symptomatology. Method: Subjects participated in two laboratory sessions that differed according to experimental condition (stress versus no stress), completed self-report measures of mood and anxiety before and after the experimental task, and were provided with an array of snack foods after each session. Results: Counter to the hypothesis, women with bulimic symptoms did not differentially increase their intake when exposed to stress. However results for the intake of each macronutrient indicated that both bulimic and control women increased their consumption of carbohydrates following the stressor. Thus, stress was related to increased carbohydrate consumption by all subjects but did not differentially affect the consumption of women with bulimic symptoms. Conclusions: It may be that women with bulimic symptoms are not differentially vulnerable to eating in response to stress or that current laboratory paradigms are unable to detect differences in eating following a stressor.
