抑郁症的理论模型认为，在压力下，特质反刍的升高预示着更明显或更长时间的负面情感和神经内分泌反应，特质反刍阻碍了从工作记忆中去除不相关的负面信息。我们研究了几个差距，这些模型的背景下，实验室引起的压力。非抑郁症的大学生完成了反刍问卷和消极评价特里尔社会压力测试（n=55）或非评价控制条件（n=69），其次是一个修改后的斯滕贝格情感工作记忆任务，评估在何种程度上无关的负面信息可以从工作记忆清空。我们测量了四次羞耻感、消极和积极的情感以及唾液皮质醇。多层次的增长曲线模型显示反刍和压力交互预测皮质醇反应，然而，相反的预测，更大的反刍与钝化皮质醇反应压力。升高的特质反刍与压力相互作用，以预测增强的羞耻反应。反刍和压力没有显着的相互作用，以预测工作记忆的表现，但在控制条件下，反刍预测更大的困难更新工作记忆。研究结果支持一种特质反刍的能力-压力模型，在非抑郁的新兴成年人中，这种模型具有较高的羞耻反应和皮质醇失调，而不是高反应性，但我们不能提供证据表明，工作记忆过程在急性压力后立即变得至关重要。
Theoretical models of depression posit that, under stress, elevated trait rumination predicts more pronounced or prolonged negative affective and neuroendocrine responses, and that trait rumination hampers removing irrelevant negative information from working memory. We examined several gaps regarding these models in the context of lab-induced stress. Non-depressed undergraduates completed a rumination questionnaire and either a negative-evaluative Trier Social Stress Test (n=55) or a non-evaluative control condition (n=69), followed by a modified Sternberg affective working memory task assessing the extent to which irrelevant negative information can be emptied from working memory. We measured shame, negative and positive affect, and salivary cortisol four times. Multilevel growth curve models showed rumination and stress interactively predicted cortisol reactivity; however, opposite predictions, greater rumination was associated with blunted cortisol reactivity to stress. Elevated trait rumination interacted with stress to predict augmented shame reactivity. Rumination and stress did not significantly interact to predict working memory performance, but under control conditions, rumination predicted greater difficulty updating working memory. Results support a vulnerability-stress model of trait rumination with heightened shame reactivity and cortisol dysregulation rather than hyper-reactivity in non-depressed emerging adults, but we cannot provide evidence that working memory processes are critical immediately following acute stress.
