【摘要】 为了验证匹兹堡睡眠质量指数(PSQI)的测试信度和效度,以112名正常成人、560名大学生和符合中国精神疾病分类方案与诊断标准第二版诊断标准的45例失眠症、39例抑郁症和37例神经症病人为测试对象,应用心理测量与统计分析技术进行了验证。结果显示,PSQI 有较好的内部一致性、再测信度、构想效度和实证效度。以 PSQI>7为界值,判断病例与正常人的灵敏度和特异度分别为98.3%和90.2%(Kappa=0.89,P<0.01)。提示 PSQI 适合我国精神科临床和睡眠质量评价研究。

【Abstract】 The authors made a study of the reliability and validity of the Pittsburgh sleep quality in- dex (PSQI),in the subjects of 112 normal adults,560 college students,45 patients with insomnia,39 patiens with depression and 37 patients with neurosis.All of the patients were diagnosed with CCMD-2. The psychological testing and the statistical techniques were used in the study.The results showed that PSQI had good,internal consistency,test-retest reliability,and high consceiving and criterion-related validity.A global PSQI score over 7 yielded a diagnostic sensitivity of 98.3% and specificity of 90.2% in distinguishing normal subjects from patients with sleep quality problems.The good clinical metrical properties of PSQI suggest its utility both in Chinese psychiatric clinical practice and research activities.
