Despite being used commonly in sleep medicine, the term "sleep quality" has not been rigorously defined. The purpose of this article is to consider objective measures of the subjective "sleep quality" experience. In order to do so, it was necessary to choose a definition of "sleep quality" as a basis for discussion. We have chosen to employ the simple Likert-style rating of (the previous night's) sleep quality, commonly included as an item on sleep diaries, as the core sleep quality indicator and focus of this article. The potential objective measures discussed include polysomnography, cyclic alternating pattern and actigraphy. We review the strengths and weaknesses of these measures as well as discuss challenges facing the development of an objective correlate of "sleep quality" ratings, including that such ratings may reflect non-sleep phenomena such as mood or health status and the possibility that "sleep quality" may reflect different aspects of sleep among people. We also discuss new approaches intended to address these challenges, including: (1) combining different types of measures; (2) sub-grouping individuals based on clinical or physiological characteristics and developing different measures in these subgroups; and (3) sub-grouping based on the association of potential measures and quality ratings over nights.
尽管“睡眠质量”一词在睡眠医学中被广泛使用，但尚未得到严格定义。本文旨在探讨主观“睡眠质量”体验的客观测量方法。为此，有必要选择一个“睡眠质量”的定义作为讨论的基础。我们选择采用睡眠日记中常见的对（前一晚）睡眠质量的简单李克特式评分，作为核心睡眠质量指标和本文的重点。所讨论的潜在客观测量方法包括多导睡眠图、周期性交替模式和活动记录仪。我们回顾了这些测量方法的优缺点，并讨论了开发与“睡眠质量”评分相关的客观指标所面临的挑战，包括此类评分可能反映情绪或健康状况等非睡眠现象，以及“睡眠质量”可能在不同人身上反映睡眠的不同方面。我们还讨论了旨在应对这些挑战的新方法，包括：（1）结合不同类型的测量方法；（2）根据临床或生理特征对个体进行分组，并在这些亚组中开发不同的测量方法；（3）根据潜在测量方法与多晚睡眠质量评分之间的关联进行分组。
