This paper is a report of a study to evaluate the psychometric properties of the Chinese version of the Insomnia Severity Index.
Despite the high prevalence of insomnia in older people and its detrimental impact on well-being and healthcare costs, this problem is almost always undetected and consequently under-treated. The Insomnia Severity Index is psychometrically sound in measuring perceived insomnia severity. However, it has had very limited application in non-White populations.
An instrument validation study was carried out between October 2008 and April 2009. The Insomnia Severity Index was translated into Chinese using Brislin's model and administered to a convenience sample of 585 older Chinese people recruited from three community centres for elders. Other instruments were also administered, including the Chinese version of the Pittsburgh Sleep Quality Index and the Geriatric Depression Scale.
Cronbach's alpha of the Chinese version of the Insomnia Severity Index was 0.81, with item-to-total correlations in the range of 0.34-0.67. Construct validity was supported by its moderate relationship with the Chinese Pittsburgh Sleep Quality Index and sleep efficiency. The Chinese version of the Insomnia Severity Index also indicated more severe level of insomnia in older people who reported depressed mood on the Geriatric Depression Scale. Discriminant validity was supported as the Chinese version of the Insomnia Severity Index could discriminate poorer sleepers from normal sleepers. Exploratory factor analysis identified a two-factor structure for the Chinese version of the Insomnia Severity Index in measuring the severity and impacts of insomnia on the Chinese older people.
The Chinese version of the Insomnia Severity Index is a culturally-relevant and psychometrically-sound instrument for assessing severity and impact of insomnia in Chinese community-dwelling older people. Nurses can use this tool to assess older people's perceptions of insomnia.
本文是一项研究报告，旨在评估中文版失眠严重程度指数的心理测量特性。
尽管老年人的失眠患病率很高，且对其健康和医疗成本有不利影响，但这一问题几乎从未被发现，因此也未得到适当治疗。失眠严重程度指数在测量感知到的失眠严重程度方面具有良好的心理测量特性。然而，它在非白人群体中的应用非常有限。
在 2008 年 10 月至 2009 年 4 月期间进行了一项仪器验证研究。采用 Brislin 模型将失眠严重程度指数翻译成中文，并对从三个老年人社区中心招募的 585 名中国老年人进行了便利抽样调查。还使用了其他工具，包括中文版匹兹堡睡眠质量指数和老年抑郁量表。
中文版失眠严重程度指数的 Cronbach's alpha 为 0.81，各项目与总分的相关系数在 0.34-0.67 之间。其与中文版匹兹堡睡眠质量指数和睡眠效率的中度关系支持了结构效度。中文版失眠严重程度指数还表明，在老年抑郁量表上报告情绪低落的老年人中，失眠程度更严重。区分效度得到支持，因为中文版失眠严重程度指数可以区分睡眠较差的人和正常睡眠的人。探索性因子分析确定了中文版失眠严重程度指数在测量中国老年人失眠严重程度和对其影响方面的两因素结构。
中文版失眠严重程度指数是一种文化相关且心理测量可靠的工具，可用于评估中国社区居住的老年人的失眠严重程度和影响。护士可以使用此工具评估老年人对失眠的看法。
