本研究探讨了一个潜在的机制，压力源和暴饮暴食之间的关系：具体来说，是否与行为和态度反映饮食失调的主题显示出独特的心理或生理反应的压力。女大学生参加了一项实验室研究，涉及四个心理压力的任务。血压和脉搏率进行了监测，并进行了一些心理问卷调查。分析显示，这些任务在高度和低度饮食失调者中都引起了显着的心血管和情感反应。不同压力源对心血管反应性或情绪状态的影响在两组之间没有差异。然而，与对照组相比，那些饮食失调的人报告说，他们对压力源的反应是增加了狂欢的欲望，沿着更多的全球压力，更低的自尊和更低的掌握。结果表明，高饮食紊乱的受试者报告的压力源引起的暴饮暴食欲望的增加不能被心血管反应性或负享乐状态的差异所解释，相对于低饮食紊乱的受试者对相同压力源的反应。
The present study explored a potential mechanism for the relationship between stressors and binge eating: specifically, whether subjects with behaviors and attitudes reflecting disorderd eating show distinctive psychologic or physiologic reactivity to stressors. Female undergraduates participated in a laboratory study involving four psychologically stressful tasks. Blood pressure and pulse rate were monitored, and several psychologic questionnaires were administered. Analyses revealed that the tasks provoked significant cardiovascular and affective responses in both high- and low-disordered eaters. There were no differences between groups in cardiovascular responsivity or mood state in response to diverse stressors. However, those with more disordered eating reported an increased desire to binge in response to the stressors, along with more global stress, lower self-esteem, and lower mastery than the comparison group. The results suggest that the increased desire to binge in response to stressors reported by subjects higher in disorded eating cannot be accounted for by differences in cardiovascular reactivity or negative hedonic state, relative to what subjects low in disordered eating showed in response to the same stressors.
