Social support and sleep: A meta-analysis.

OBJECTIVE: While the implications of social support are increasingly well understood, no meta-analytic review to date has examined the intersection of the social support and sleep literatures. The aims of this meta-analysis were primarily to review the association between social support and sleep and additionally to test several proposed moderators from prior work. METHOD: Using a literature search and the ancestry approach, the review identified 61 studies with a total of 105,437 participants. RESULTS: Random-effects modeling showed that greater social support was significantly related to improved sleep outcomes (Zr = -.152). These results were not moderated by the operationalization of support, study design, or chronic conditions. CONCLUSIONS: These data indicate a robust association between social support and favorable sleep outcomes. (PsycINFO Database Record
