虽然有大量证据表明主观睡眠质量差与主观幸福感降低有关，但关于客观睡眠指标与主观幸福感之间关系的研究数量较少，而且研究结果不太一致。使用美国中年调查（MIDUS）的数据，我们调查了通过体动记录仪评估的睡眠持续时间和质量是否与主观幸福感相关，以及这种关系是否由主观睡眠质量介导。对313名主要来自普通人群的白色美国人和128名年龄在35岁至85岁之间的城市居住的非洲裔美国人进行了横断面研究。睡眠持续时间，睡眠持续时间的变异性，入睡潜伏期，入睡后清醒的时间进行了评估，在7天内的活动记录。采用匹兹堡睡眠质量指数评估主观睡眠质量，采用生活满意度量表和心境与焦虑症状问卷评估积极心理健康状况和心理困扰症状。在白色和非洲裔美国人中，睡眠时间的高日间变异性与控制年龄、性别、教育和婚姻状况以及BMI的主观幸福感水平较低有关。相比之下，睡眠持续时间，入睡潜伏期，入睡后清醒时间与主观幸福感控制协变量和其他睡眠变量无关。此外，睡眠持续时间和幸福感之间的关系部分由主观睡眠质量介导。研究结果表明，睡眠持续时间的日常变化-超过平均睡眠时间-与主观睡眠质量差和主观幸福感差有关。
While there is a large body of evidence that poor subjective sleep quality is related to lower subjective well-being, studies on the relation of objective sleep measures and subjective well-being are fewer in number and less consistent in their findings. Using data of the Survey of Mid-Life in the United States (MIDUS), we investigated whether duration and quality of sleep, assessed by actigraphy, were related to subjective well-being and whether this relationship was mediated by subjective sleep quality. Three hundred and thirteen mainly white American individuals from the general population and 128 urban-dwelling African American individuals between 35 and 85 years of age were studied cross-sectionally. Sleep duration, variability of sleep duration, sleep onset latency, and time awake after sleep onset were assessed by actigraphy over a period of 7 days. Subjective sleep quality was assessed with the Pittsburgh Sleep Quality Index, positive psychological well-being and symptoms of psychological distress were assessed with the Satisfaction with Life Scale and the Mood and Anxiety Symptom Questionnaire. In both white and African Americans high day-to-day variability in sleep duration was related to lower levels of subjective well-being controlling age, gender, educational and marital status, and BMI. By contrast, sleep duration, sleep onset latency, and time awake after sleep onset were not related to subjective well-being controlling covariates and other sleep variables. Moreover, the relationship between variability in sleep duration and well-being was partially mediated by subjective sleep quality. The findings show that great day-to-day variability in sleep duration – more than average sleep duration – is related to poor subjective sleep quality and poor subjective well-being.
