In previous work we have developed a diary instrument-the Social Rhythm Metric (SRM), which allows the assessment of lifestyle regularity-and a questionnaire instrument--the Pittsburgh Sleep Quality Index (PSQI), which allows the assessment of subjective sleep quality. The aim of the present study was to explore the relationship between lifestyle regularity and subjective sleep quality. Lifestyle regularity was assessed by both standard (SRM-17) and shortened (SRM-5) metrics; subjective sleep quality was assessed by the PSQI. We hypothesized that high lifestyle regularity would be conducive to better sleep. Both instruments were given to a sample of 100 healthy subjects who were studied as part of a variety of different experiments spanning a 9-yr time frame. Ages ranged from 19 to 49 yr (mean age: 31.2 yr, s.d.: 7.8 yr); there were 48 women and 52 men. SRM scores were derived from a two-week diary. The hypothesis was confirmed. There was a significant (rho = -0.4, p < 0.001) correlation between SRM (both metrics) and PSQI, indicating that subjects with higher levels of lifestyle regularity reported fewer sleep problems. This relationship was also supported by a categorical analysis, where the proportion of "poor sleepers" was doubled in the "irregular types" group as compared with the "non-irregular types" group. Thus, there appears to be an association between lifestyle regularity and good sleep, though the direction of causality remains to be tested.
在之前的研究中，我们开发了一种日记工具——社会节律度量法（SRM），用于评估生活方式的规律性，以及一种问卷工具——匹兹堡睡眠质量指数（PSQI），用于评估主观睡眠质量。本研究的目的是探讨生活方式规律性与主观睡眠质量之间的关系。生活方式规律性通过标准度量法（SRM - 17）和简化度量法（SRM - 5）进行评估；主观睡眠质量通过PSQI进行评估。我们假设高生活方式规律性有利于更好的睡眠。这两种工具都被发放给了100名健康受试者组成的样本，这些受试者作为跨越9年时间框架的各种不同实验的一部分接受研究。年龄范围为19至49岁（平均年龄：31.2岁，标准差：7.8岁）；其中有48名女性和52名男性。SRM分数来自为期两周的日记。该假设得到了证实。SRM（两种度量法）与PSQI之间存在显著相关性（rho = -0.4，p < 0.001），表明生活方式规律性较高的受试者报告的睡眠问题较少。这种关系也得到了分类分析的支持，在该分析中，“睡眠不佳者”在“不规律类型”组中的比例是“非不规律类型”组中的两倍。因此，生活方式规律性与良好睡眠之间似乎存在关联，尽管因果关系的方向仍有待检验。
