摘要:
目的 评估失眠严重指数量表(ISI)中文版的心理测量学特征。方法 选取某工商学校 的3 969 名学生,睡眠质量采用匹兹堡睡眠质量指数(PSQI)量表评定、失眠严重程度采用ISI评定、白天 嗜睡程度采用爱泼沃斯嗜睡量表(ESS)评定、抑郁状况采用贝克抑郁量表(BDI)评定、焦虑状况采用宗 式焦虑自评量表(SAS)评定,并收集了受试者的一般资料。2 915 名(73%)学生在9 个月后完成了ISI 重 测。结果 首测ISI 分为(5.82 ±4.60)分(0~28 分),呈现正偏态分布;其趋向于单因子结构(方差解释值 为52%),条目载荷范围为0.62~0.80,KMO=0.87,Bartlett 球形检验的P< 0.001;条目与总分的相关系数 为0.63~0.79,Spearman Brown 分半信度和Chronbach's α 系数为0.75 和0.84(均P < 0.001)。首测ISI 分 与ESS 分、BDI分与SAS分存在相关性,而ISI分与PSQI分无相关性。首测和复测ISI总分和各个条目的 效应量(Cohen's d),除了条目5(Cohen's d=0.361),其他均< 0.1。结论 ISI(中文版)有较好的效度和信度, 适于青年失眠严重程度的评估。该青年群体的失眠发生率较高(30.2%),而且稳定存在,需要予以关注。

Psychometric property of the Insomnia Severity Index in students of a commercial school
()
Abstract:
Objectives To evaluate the psychometric property of the Insomnia Severity Index( Chinese version) in students of a commercial school. Methods A total of 3 969 students of a commercial school were selected. Their sleep quality, insomnia, anxiety, daytime sleepiness, and depression were evaluated by the Pittsburgh sleep quality index( PSQI), the Insomnia Severity Index( ISI), Self-Rating Anxiety Scale( SAS), Epworth Sleepiness Scale( ESS), Beck Depression Inventory( BDI), respectively. Their general information was also gathered. After 9 months, 73% of the students( n=2 915) were re-evaluated by the ISI. Results The score of ISI in the first test were 5.8±4.6( 0-28), in a skewed normal distribution. It had a single factor structure (interval variance value was 52%); the item loading ranged from 0.62 to 0.80; KMO=0.87; Bartlett spherical test result was P < 0.001; the correlation coefficient between the item and the total score was 0.63-0.79; Spearman-Brown semi-reliability and Cronbach alpha coefficients were 0.75 and 0.84( P< 0.001). There was a significant correlation between the first test ISI score and the ESS score, BDI score and SAS score, while the ISI score was not statistically related to the PSQI score. The effect size( Cohen's d) of the total score and each item of ISI between the first test and the second test was less than 0.1, except for item 5( Cohen's d=0.361). Conclusions The ISI( Chinese version) has good psychometric property, so it is suitable for evaluating insomnia among adolescents. Moreover, attention should be paid to the prevalence of insomnia in these young adults( 30.2%)
