目的：匹兹堡睡眠质量指数（PSQI）对原发性失眠症的心理测量学评价方法：研究样本包括80例原发性失眠症患者（DSM-IV）。重测间隔时间为2天或数周。有效性分析计算PSQI数据和数据从睡眠日记，以及多导睡眠图，以评估的特异性PSQI，失眠患者进行了比较，与对照组的45名健康subjects.Results：在原发性失眠患者，整体PSQI总分相关系数的重测信度为0.87。有效性分析显示PSQI和睡眠日志数据之间的相关性较高，与多导睡眠图数据的相关性较低。PSQI总分> 5分，作为失眠症患者与对照组的睡眠障碍指标的敏感性为98.7，特异性为84.4。结论：PSQI对原发性失眠症患者具有较高的重测信度和效度。(C)2002年爱思唯尔科技有限公司All rights reserved.
Objective: Psychometric evaluation of the Pittsburgh Sleep Quality Index (PSQI) for primary insomnia.Methods: The study sample consisted of 80 patients with primary insomnia (DSM-IV). The length of the test-retest interval was either 2 days or several weeks. Validity analyses were calculated for PSQI data and data from sleep diaries, as well as polysomnography, To evaluate the specificity of the PSQI, insomnia patients were compared with a control group of 45 healthy subjects.Results: In primary insomnia patients, the overall PSQI global score correlation coefficient for test-retest reliability was .87. Validity analyses showed high correlations between PSQI and sleep log data and lower correlations with polysomnography data. A PSQI global score > 5 resulted in a sensitivity of 98.7 and specificity of 84.4 as a marker for sleep disturbances in insomnia patients versus controls.Conclusion: The PSQI has a high test-retest reliability and a good validity for patients with primary insomnia.
