目的检验中文版失眠严重程度指数(ISI-C)量表在临床失眠患者中的信度和效度。
方法选取大连大学附属中山医院确诊为临床失眠的患者120例作为研究对象。研究对象需同时完成ISI-C量表、匹兹堡睡眠质量指数(PSQI)量表、Epworth嗜睡量表(ESS)。通过Cronbach α系数、条目相关性分析、探索性因子分析和ROC曲线检验量表的信效度。
结果ISI-C量表的内部一致性信度Cronbach α系数为0.804,重测信度为0.887( P<0.01)。ISI-C量表与PSQI量表( r=0.831, P<0.01)、ESS量表( r=0.218, P<0.05)总分均具有相关性。探索性因子分析提取2个公因子,分别为失眠的严重程度和失眠的影响,累计方差贡献率为63.117%( P<0.01)。当ISI-C量表切点为10.5分时,敏感度和特异度分别为84.0%、92.3%( P<0.01)。
结论ISI-C量表具有良好的信效度,适合在国内对临床患者进行失眠评估。
ObjectiveTo test the reliability and validity of the Chinese version of Insomnia Severity Index(ISI-C) in patients with insomnia.
MethodsOne hundred and twenty patients with insomnia were selected from Zhongshan Hospital Affiliated to Dalian University. The subjects had completed the ISI-C scale and Pittsburgh Sleep quality Index(PSQI) scale, Epworth Sleepiness Scale(ESS) at the same time. The reliability and validity of the scale were tested by Cronbach α coefficient, item correlation analysis, exploratory factor analysis and ROC curve test.
ResultsThe Cronbach α coefficient of the ISI-C was 0.804,the test-retest reliability was 0.887 ( P<0.01). The items of ISI-C scale were correlated with the corresponding items of PSQI ( r=0.831, P<0.01), ESS( r=0.218, P<0.05). Two common factors were extracted by factor analysis including the severity of insomnia and the influence of insomnia, and the cumulative contribution rate was 63.117%( P<0.01).When the cutting point was 10.5 points, the sensitivity and specificity were 84.0% and 92.3%, respectively ( P<0.01).
ConclusionsISI-C scale is a reliable and valid instrument. It can be used to measure the insomnia of patients in hospitals.
