抑郁症和抑郁症是不同的临床现象，但他们是高度共病。高合并症发生率的一个可能解释是风险因素的重叠。例如，对压力的非典型反应会使个体面临更大的失眠和抑郁风险。本研究的目的是同时评估与压力相关的睡眠障碍（睡眠反应）的脆弱性和对压力事件（负面认知方式）做出负面归因的倾向，以及它们与失眠和抑郁症的关系。研究参与者包括从美国一所大型公立大学招募的224名本科生。分别采用福特应激反应测试（FIRST）和认知方式问卷（CSQ）评估睡眠反应和消极认知方式。采用抑郁严重程度指数（ISI）评估抑郁症状，采用流行病学研究中心抑郁量表（CES-D）测量抑郁症状。睡眠反应与更严重的失眠和抑郁症状独立相关。此外，消极的认知方式与更严重的抑郁症状有关，这种影响部分由睡眠反应介导。目前的研究结果表明，睡眠反应可能有助于失眠以外的疾病的发展。这些发现进一步支持使用跨学科的方法来调查病因学模型，更具体地说，进一步探索多重压力反应（在认知，睡眠等方面）使个体处于更大的发展精神病理学的风险中。
Insomnia and depression are distinct clinical phenomena, yet they are highly comorbid. One potential explanation for the high comorbidity rates is the overlap in risk factors. Atypical responses to stress, for example, place individuals at greater risk for both insomnia and depression. The goal of the present study was to simultaneously assess vulnerability to stress-related sleep disturbance (sleep reactivity) and the tendency to make negative attributions about stressful events (negative cognitive style), and how they relate to insomnia and depression. Study participants included 224 undergraduate students recruited from a large, public university in the United States. Sleep reactivity and negative cognitive style were assessed using the Ford Insomnia Response to Stress Test (FIRST) and the Cognitive Style Questionnaire (CSQ), respectively. Insomnia symptoms were assessed using the Insomnia Severity Index (ISI), and depressive symptoms were measured using the Center for Epidemiologic Studies Depression Scale (CES-D). Sleep reactivity was independently associated with greater insomnia and depression symptoms. Additionally, a negative cognitive style was related to greater depressive symptoms, and this effect was partially mediated by sleep reactivity. The current findings suggest that sleep reactivity may contribute to the development of disorders beyond insomnia. These findings further support the use of an interdisciplinary approach to investigating etiological models, and more specifically, the further exploration of how multiple stress responses (in terms of cognitions, sleep, etc.) place individuals at greater risk for developing psychopathology.
