In this study, we used data from the second wave of Midlife in the United States (MIDUS) Study, MIDUS Biomarkers and MIDUS 3. We applied the serial mediation model to explore the serial mediating effects of perceived stress and depressive symptoms on the relationship between sleep quality and life satisfaction. A total of 945 participants were included in our study. The total indirect effect of sleep quality on life satisfaction through perceived stress, depressive symptoms and the combination of perceived stress and depressive symptoms accounted for within the overall model was 45.5%. At the intervention level, programs designed to improve the level of life satisfaction among adults should focus on perceived stress and depressive symptoms. The prevention of perceived stress and depression contributes to improving life satisfaction and wellbeing. The serial mediation results should be confirmed by further longitudinal study.
在本研究中，我们使用了美国中年（MIDUS）研究第二轮、MIDUS生物标志物研究和MIDUS 3的数据。我们应用序列中介模型来探讨感知压力和抑郁症状在睡眠质量与生活满意度之间关系中的序列中介作用。我们的研究共纳入了945名参与者。在总体模型中，睡眠质量通过感知压力、抑郁症状以及感知压力和抑郁症状的组合对生活满意度产生的总间接效应占45.5%。在干预层面，旨在提高成年人生活满意度水平的项目应关注感知压力和抑郁症状。预防感知压力和抑郁有助于提高生活满意度和幸福感。序列中介结果应通过进一步的纵向研究加以证实。
