A sizeable literature has implicated sleep in the phenomenological experience of various mood disorders, vulnerability to psychopathology, and overall poor psychological functioning. By contrast, positive affective states (e.g., joy, happiness, vigor, positive mood) that may contribute to sleep have been understudied. This systematic review integrates findings from cross-sectional, longitudinal, ambulatory, and experimental studies that investigate the association between positive affect and sleep. A comprehensive search for all available research on the topic was performed in three electronic bibliographic databases (PubMed, PsycINFO, CINAHL). Two independent reviewers extracted data on study characteristics and quality. From 10,853 retrieved articles, 44 fulfilled inclusion criteria and formed the base of the review. The majority of studies (68.2%, n = 30) were classified as weak or having high risk of bias. In general, the pattern of findings suggests that aggregate or trait measures provide the most consistent evidence of an association between positive affect and sleep in healthy populations. More limited empirical data exist on the association between positive affect and sleep in clinical populations. We conclude that more rigorous and theoretically informed research is needed before firm conclusions can be drawn about the possible beneficial impact of positive affect on sleep outcomes.
大量文献表明，睡眠与各种情绪障碍的现象体验、精神病理学易感性以及整体较差的心理功能有关。相比之下，积极的情感状态（例如，快乐、幸福、活力、积极的情绪）可能对睡眠有贡献，但它们的研究却相对较少。本系统评价整合了横断面研究、纵向研究、动态研究和实验研究的结果，这些研究调查了积极情绪与睡眠之间的关联。在三个电子文献数据库（PubMed、PsycINFO 和 CINAHL）中对该主题的所有可用研究进行了全面搜索。两名独立的综述作者提取了研究特征和质量的数据。从检索到的 10853 篇文章中，有 44 篇符合纳入标准，构成了本综述的基础。大多数研究（68.2%，n=30）被归类为弱或高偏倚风险。总的来说，研究结果表明，在健康人群中，积极情绪与睡眠之间的关联，综合或特质测量提供了最一致的证据。在临床人群中，积极情绪与睡眠之间的关联存在更有限的经验数据。我们的结论是，在得出关于积极情绪对睡眠结果可能产生有益影响的明确结论之前，需要进行更严格和理论上更有依据的研究。
