Restorative sleep is a commonly used term but a poorly defined construct. Few studies have assessed restorative sleep in nationally representative samples. We convened a panel of 7 expert physicians and researchers to evaluate and enhance available measures of restorative sleep. We then developed the revised Restorative Sleep Questionnaire (REST-Q), which comprises 9 items assessing feelings resulting from the prior sleep episode, each with 5-point Likert response scales. Finally, we assessed the prevalence of high, somewhat, and low REST-Q scores in a nationally representative sample of US adults (n= 1,055) and examined the relationship of REST-Q scores with other sleep and demographic characteristics. Pairwise correlations were performed between the REST-Q scores and other self-reported sleep measures. Weighted logistic regression analyses were conducted to compare scores on the REST-Q with demographic variables. The prevalence of higher REST-Q scores (4 or 5 on the Likert scale) was 28.1% in the nationally representative sample. REST-Q scores positively correlated with sleep quality (r=0.61) and sleep duration (r=0.32), and negatively correlated with both difficulty falling asleep (r=-0.40) and falling back asleep after waking (r=-0.41). Higher restorative sleep scores (indicating more feelings of restoration upon waking) were more common among those who were: ≥60 years of age (OR=4.20, 95%CI: 1.92-9.17); widowed (OR=2.35, 95%CI:1.01-5.42), and retired (OR=2.02, 95%CI:1.30-3.14). Higher restorative sleep scores were less frequent among those who were not working (OR=0.36, 95%CI: 0.10-1.00) and living in a household with two or more persons (OR=0.51,95%CI:0.29-0.87). Our findings suggest that the REST-Q may be useful for assessing restorative sleep.
恢复性睡眠是一个常用术语，但却是一个定义模糊的概念。很少有研究在全国代表性样本中评估恢复性睡眠。我们召集了一个由7名专家医生和研究人员组成的小组，以评估和改进现有的恢复性睡眠测量方法。然后，我们开发了修订版的恢复性睡眠问卷（REST-Q），它包含9个项目，用于评估前一晚睡眠后的感受，每个项目都有5点李克特量表。最后，我们在美国成年人的全国代表性样本（n = 1055）中评估了REST-Q高分、中等分数和低分的患病率，并研究了REST-Q分数与其他睡眠和人口统计学特征之间的关系。对REST-Q分数与其他自我报告的睡眠测量方法进行了成对相关性分析。进行加权逻辑回归分析，以比较REST-Q分数与人口统计学变量。在全国代表性样本中，REST-Q高分（李克特量表上为4或5）的患病率为28.1%。REST-Q分数与睡眠质量（r = 0.61）和睡眠时间（r = 0.32）呈正相关，与入睡困难（r = -0.40）和醒来后再次入睡困难（r = -0.41）呈负相关。较高的恢复性睡眠分数（表明醒来后恢复感更强）在以下人群中更为常见：年龄≥60岁（OR = 4.20，95%CI：1.92 - 9.17）；丧偶（OR = 2.35，95%CI：1.01 - 5.42），以及退休（OR = 2.02，95%CI：1.30 - 3.14）。在没有工作的人群（OR = 0.36，95%CI：0.10 - 1.00）和与两个或更多人同住的家庭中的人群（OR = 0.51，95%CI：0.29 - 0.87）中，较高的恢复性睡眠分数不太常见。我们的研究结果表明，REST-Q可能有助于评估恢复性睡眠。
