睡眠品質是判定睡眠良好與否的重要指標。當睡眠品質不良時，會延緩疾病復原與降低生活品質。近年來，護理領域廣為使用睡眠品質作為睡眠相關研究之重要指標，然而，在過去文獻中卻缺乏對睡眠品質的概念進行系統性分析。本文依據Walker及Avant（2005）的概念分析步驟分析睡眠品質，結果發現：⑴睡眠品質定義性屬性為主觀感受、計算睡眠的量與清醒後活動評量。⑵前因包括能進入睡眠週期以及有意識狀態。⑶後果會影響生理功能、心理情緒反應、社會互動與工作能力及整體性的生活品質。⑷睡眠品質評估的工具涵蓋睡眠品質問卷（主觀性）及生理測量方式（客觀性），如活動腕表、腦波圖。期望能使護理人員瞭解睡眠品質的概念，運用工具評量真實的睡眠品質，做為睡眠品質相關議題的實務與研究上之依據。

Poor sleep quality may impede recovery from illness and cause quality of life to decline. An increas-ing number of nurses today use sleep quality as a primary indicator to measure the nature of sleep
in the nursing research feld. Therefore, understanding the concept of sleep quality is necessary for nurses. This paper was designed to review the concept of sleep quality using Walker and Avant’s (2005)
concept analysis. Results indicate that: (1) defning attributes of sleep quality include subjective per-ception of sleep, actual sleep hours and evaluation of activity after awaking; (2) antecedents of sleep
quality include subject ability to get naturally into the sleep cycle and status of conscious state; (3) consequences of sleep quality may affect physical, psychological, social, and global dimensions; (4) among the many instruments that may be used to assess sleep quality include self-reported question-naires and physiological measurement tools. The purpose of this paper was to help nurses better com-prehend the concept of sleep quality and propose an approach to evaluate in both clinical and research settings subjects suffering from sleep-related problems using concept analysis.
