This study investigates the complex relationships among social support, social strain, loneliness, cognitive status, and sleep quality in adults aged 51 and above. It aims to explore loneliness as a mediator between social support, social strain, and sleep quality and to examine if, and how, the mediating effect differs by cognitive status.
Eight years of data from the University of Michigan Health and Retirement Study were analyzed using a cross-lagged panel model. Moderated mediation analyses examined loneliness's mediating effect and cognitive status's moderating influence on the associations among social support, social strain, and sleep quality.
Loneliness mediated the relationships between social support, social strain, and sleep quality. Individuals with better cognitive function experienced an increased influence of social support on sleep quality by mitigating loneliness.
Considering the moderating role of cognitive status, sleep interventions individualized and tailored to these differences become essential.
本研究调查了51岁及以上成年人的社会支持、社会压力、孤独感、认知状态和睡眠质量之间的复杂关系。旨在探讨孤独感作为社会支持、社会压力和睡眠质量之间的中介，并检验中介效应是否以及如何因认知状态而异。
使用交叉滞后面板模型分析了来自密歇根大学健康与退休研究的八年数据。调节中介分析检验了孤独感的中介效应以及认知状态对社会支持、社会压力和睡眠质量之间关联的调节作用。
孤独感介导了社会支持、社会压力和睡眠质量之间的关系。认知功能较好的个体通过减轻孤独感，使社会支持对睡眠质量的影响增加。
考虑到认知状态的调节作用，针对这些差异进行个性化和量身定制的睡眠干预变得至关重要。
