Although the adverse link between rumination and sleep quality is well established, much of the literature neglects the role of social factors. This study examined the role of older adults’ perceived social support from spouses and from family/friends in modifying the association between trait rumination and sleep quality. Existing hypotheses suggest that social support may play three unique roles, each tested within the current study: (H1) support may act as a protective factor that buffers negative effects of rumination on sleep quality, (H2) support may curtail rumination and, in turn, promote sleep quality, and (H3) rumination may erode support and, in turn, undermine sleep quality.

老年人的反刍和睡眠质量：检验社会支持的作用

尽管反刍与睡眠质量之间的不利联系已经确立，但大部分文献都忽略了社会因素的作用。这项研究检验了老年人从配偶和家人/朋友那里获得的社会支持在改变特质沉思与睡眠质量之间的关联方面的作用。现有的假设表明，社会支持可能扮演三个独特的角色，每个角色都在当前的研究中进行了测试：（H1）支持可以作为一种保护因素，缓冲沉思对睡眠质量的负面影响，（H2）支持可以减少沉思，反过来，促进睡眠质量，并且（H3）沉思可能会削弱支持，进而破坏睡眠质量。
