性格乐观与对身体健康结果的有益影响有关。然而，它与全球睡眠质量的联系以及负责这种关联的心理调节因素的研究较少。因此，这项研究检验了特质乐观是否可以预测整体睡眠质量，以及主观幸福感的衡量标准是否是这种联系的统计中介因素。 175 名参与者（93 名男性，82 名女性）组成的社区样本完成了乐观特质、抑郁和生活满意度的测量。使用匹兹堡睡眠质量指数评估全球睡眠质量。结果表明，乐观特质是 PSQI 整体睡眠质量改善的有力预测因素。此外，在单一和多重中介模型中，这种关联都是由抑郁和生活满意度介导的。这些结果强调了乐观对于睡眠恢复过程的重要性，以及多种中介模型在测试不同心理路径中的效用。
Dispositional optimism has been related to beneficial influences on physical health outcomes. However, its links to global sleep quality and the psychological mediators responsible for such associations are less studied. This study thus examined if trait optimism predicted global sleep quality, and if measures of subjective well-being were statistical mediators of such links. A community sample of 175 participants (93 men, 82 women) completed measures of trait optimism, depression, and life satisfaction. Global sleep quality was assessed using the Pittsburgh Sleep Quality Index. Results indicated that trait optimism was a strong predictor of better PSQI global sleep quality. Moreover, this association was mediated by depression and life satisfaction in both single and multiple mediator models. These results highlight the importance of optimism for the restorative process of sleep, as well as the utility of multiple mediator models in testing distinct psychological pathways.
