影響老人睡眠品質的危險因素如生活形態、身體的疾患、心理的因素及性別等，已在許多有關睡眠的研究中很明確的被陳述，然而，針對華裔老人在睡眠品質及其影響因素的探討，目前在國內外的研究仍有限。本研究的目的在探討移民西雅圖華裔老人的睡眠品質和它的影響因素。本研究為一描述性和相關性研究，以問卷調查法，針對西雅圖中國老人日間照護中心、三所當地中國教會、個案住宅及中國老人退休公寓，收集了80名年齡居於66到93歲的中國移民老人為研究對像。研究者採一對一的訪談方式並協助問卷完成。研究結果顯示：(1) 44名 (55%) 研究對象為睡眠品質差，而36名 (45%) 的個案有好的睡眠品質；(2) 憂鬱情形及患病的多寡與睡眠品質有統計上顯著的差異 (分別為r = .4775，p = .000, 及 r = .221, p = .049）；(3)針對這群移民老人，白天的睡眠並不影響夜間的睡眠情形。研究結果可提供醫護人員有關老人睡眠問題的相關訊息，藉以增進老人們的生活品質。

　　　　　The risk factors related to quality of sleep in elderly adults, such as life-style events, physical illness, psychological factors, and gender have been well identified by several studies. However, information regarding the relationship between quality of sleep and its related factors among elderly Chinese immigrants is not available in recent sleep literature. The purposes of this study were to explore the quality of sleep and discover the relationships between sleep quality and its related factors among elderly Chinese immigrants people in the Seattle area. Pearson's correlation and descriptive statistics were used to analyze data. Eighty community-dwelling Chinese elderly people, aged from 66 to 93, were recruited from the Chinese Senior Day Care Center, local Chinese churches, elderly Chinese individuals' private homes, and Chinese retirement apartments within the Seattle area. Three questionnaires were utilized to collect data, and personal interviews were used to facilitate the subjects in completing the questionnaires. The findings of this study showed that (1) 55% (n = 44) of the participants were identified as poor sleepers and 45% (n = 36) as good sleepers. (2) depression and the number of current diseases experienced by the subjects were in statistically significant correlation with quality of sleep, with r= .477, p= .00 and r= .221, p= .049 respectively. (3) daytime napping did not affect nighttime sleep in this study' population. The findings of this study can provide information regarding sleep problems among elderly Chinese immigrants to improve the elderly's quality of sleep.
