匹兹堡睡眠质量指数（PSQI）通过自我报告对1个月的睡眠质量和睡眠障碍进行回顾性测量。虽然PSQI已在各种人群中使用，但已发表的心理测量数据有限。本研究的目的是检测四种人群PSQI的心理测量特性：骨髓移植患者（n = 155）；肾移植患者（n = 56）；患有乳腺癌的妇女（n = 102）；有良性乳房问题的女性（n = 159）。结果支持PSQI的内部一致性、信度和结构效度。各组间的Cronbach's alpha值为0.80，整体得分和成分得分之间的相关性为中等至高。PSQI得分与睡眠质量和睡眠问题的测量有中度到高度的相关性，与不相关的构式相关性较差。有睡眠问题的人。与没有这些问题的人相比，睡眠质量差和睡眠不安的人的PSQI得分明显更高。(C) 1998爱思唯尔科学有限公司
The Pittsburgh Sleep Quality Index (PSQI) measures sleep quality and disturbance retrospectively over a 1-month period using self-reports. Although the PSQI has been used in a variety of populations, published psychometric data are limited. The goal of this study was to examine psychometric properties of the PSQI among four populations: bone marrow transplant patients (n = 155); renal transplant patients (n = 56); women with breast cancer (n = 102); and women with benign breast problems (n = 159). Results supported PSQI internal consistency reliability and construct validity. Cronbach's alphas were 0.80 across groups and correlations between global and component scores were moderate to high. PSQI scores were moderately to highly correlated with measures of sleep quality and sleep problems, and poorly correlated with unrelated constructs. Individuals with sleep problems. poor sleep quality, and sleep restlessness had significantly higher PSQI scores in comparison to individuals without such problems. (C) 1998 Elsevier Science Inc.
