匹兹堡睡眠质量指数（PSQI）常用于评估患者的睡眠问题。本研究的目的是为该问卷提供参考值，测试心理测量学特性，并分析与心理，社会人口和行为因素的关联。使用PSQI和其他几份问卷对18-80岁的儿童进行了调查。根据普遍接受的截止值（PSQI > 5），36%的普通人群睡眠不好。女性报告的睡眠问题明显多于男性（平均得分：M = 5.5 vs. M = 4.4;效应量d = 0.35），但年龄和睡眠质量之间没有线性关系。睡眠问题与疲劳、生活质量（身体和精神）、身体不适、焦虑和缺乏乐观有关。睡眠质量也与社会经济地位、职业状况（失业者睡眠质量最差）和肥胖密切相关。除了结果的PSQI总分，平均得分的睡眠质量的具体组成部分（睡眠潜伏期，睡眠持续时间，睡眠药物的使用）。结论：PSQI被证明是一个合适的仪器测量睡眠质量。在比较各组患者的睡眠问题时，应考虑性别差异、心理因素和肥胖。(C)© 2016 Elsevier B.

Background: The Pittsburgh Sleep Quality Index (PSQI) is frequently used to assess sleep problems in patients. The aim of this study was to provide reference values for this questionnaire, to test psychometric properties, and to analyze associations with psychological, sociodemographic, and behavioral factors.Methods: A German community sample comprising 9284 adult residents (aged 18-80 years) was surveyed using the PSQI and several other questionnaires.Results: According to the generally accepted cut-off (PSQI > 5), 36% of the general population slept badly. Females reported significantly more sleep problems than males (mean scores: M = 5.5 vs. M = 4.4, respectively; effect size d = 0.35), but there was no linear association between age and sleep quality. Sleep problems were correlated with fatigue, quality of life (physical as well as mental), physical complaints, anxiety, and lack of optimism. Sleep quality was also strongly associated with socioeconomic status, professional situation (poorest sleep quality in unemployed people), and obesity. In addition to the results of the PSQI total score, mean scores of specific components of sleep quality were presented (sleep latency, sleep duration, and use of sleep medication).Conclusion: The PSQI proved to be a suitable instrument for measuring sleep quality. Gender differences, psychological factors, and obesity should be taken into account when groups of patients are compared with respect to sleep problems. (C) 2016 Elsevier B.V. All rights reserved.
