尽管精神病患者普遍存在睡眠投诉，但很少有专门设计的问卷来衡量临床人群的睡眠质量。匹兹堡睡眠质量指数（PSQI）是一个自我评估的问卷，评估睡眠质量和干扰超过1个月的时间间隔。19个单独的项目产生7个“组成部分”分数：主观睡眠质量，睡眠潜伏期，睡眠持续时间，习惯性睡眠效率，睡眠障碍，使用睡眠药物和日间功能障碍。这七个组成部分的得分之和产生一个总体得分。PSQI的临床和临床特征在18个月的时间内进行了评估，包括“良好”睡眠者（健康受试者，n = 52）和“较差”睡眠者（抑郁患者，n = 54;睡眠障碍患者，n = 62）。内部同质性，一致性（重测信度）和有效性的可接受的措施。PSQI总分> 5分的患者在区分睡眠质量好和睡眠质量差方面的诊断敏感性为89.6%，特异性为86.5%（kappa = 0.75，p < 0.001）。PSQI的临床和临床特性表明其在精神病临床实践和研究活动中的实用性。
Despite the prevalence of sleep complaints among psychiatric patients, few questionnaires have been specifically designed to measure sleep quality in clinical populations. The Pittsburgh Sleep Quality Index (PSQI) is a self-rated questionnaire which assesses sleep quality and disturbances over a 1-month time interval. Nineteen individual items generate seven "component" scores: subjective sleep quality, sleep latency, sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction. The sum of scores for these seven components yields one global score. Clinical and clinimetric properties of the PSQI were assessed over an 18-month period with "good" sleepers (healthy subjects, n = 52) and "poor" sleepers (depressed patients, n = 54; sleep-disorder patients, n = 62). Acceptable measures of internal homogeneity, consistency (test-retest reliability), and validity were obtained. A global PSQI score > 5 yielded a diagnostic sensitivity of 89.6% and specificity of 86.5% (kappa = 0.75, p < 0.001) in distinguishing good and poor sleepers. The clinimetric and clinical properties of the PSQI suggest its utility both in psychiatric clinical practice and research activities.
