The aim of this study was to investigate the psychometric properties of the Chinese version of the Sleep Health Index (SHI-C) among pregnant women.
Cross-sectional design.
Outpatient clinic of three hospitals in China.
Pregnant women (N = 264) aged between 18 and 45 years were recruited via convenience sampling.
The Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS) and Insomnia Severity Index (ISI) were used to measure sleep quality, daytime sleepiness, and insomnia, respectively. The Fatigue Assessment Scale (FAS) and the Edinburgh Postnatal Depression Scale (EPDS) were used to measure fatigue and depression, respectively. Structural validity was assessed via confirmatory factor analysis (CFA). Concurrent and convergent validity were assessed using bivariate correlation analyses. Known-group validity was assessed by comparing the SHI-C score between different groups. Cronbach's α was calculated for reliability.
The average sample age was 30.6 years old and their average score of SHI-C was 86.4 (SD 8.2). Based on PSQI, ISI, and ESS, 43.6%, 32.2%, and 26.9% had poor sleep quality, insomnia, and excessive daytime sleepiness, respectively. The SHI-C total and sleep quality sub-index scores had moderate to strong correlations with both PSQI (r=-0.542, p<0.01; r=-0.648, p<0.01) and ISI (r=-0.692, p<0.01; r=-0.752, p<0.01). The SHI-C total and sleep quality sub-index scores were significantly associated with ESS, FAS, and EPDS (r=-0.171 to -0.276; p<0.01). The SHI-C total score was higher in the second trimester and among those who were working, never drank coffee, or took a nap every day. The Cronbach's α of the SHI-C total and the sleep quality sub-index were 0.723 and 0.806, respectively. The Cronbach's α of sleep duration and disordered sleep sub-indices were 0.594 and 0.545, respectively.
Overall, the SHI-C has good validity and acceptable reliability among the pregnant population in China. It can be a useful tool for the assessment of sleep health. More research is warranted to refine the sleep duration and disordered sleep sub-indices.
The use of SHI-C would facilitate the assessment of sleep health among pregnant women, which could contribute to the promotion of perinatal care.
本研究旨在调查中文版睡眠健康指数(SHI-C)在孕妇中的心理测量特性。
横断面设计。
中国三家医院的门诊。
通过便利抽样招募了年龄在 18 至 45 岁之间的孕妇(N=264)。
使用匹兹堡睡眠质量指数(PSQI)、Epworth 嗜睡量表(ESS)和失眠严重程度指数(ISI)分别测量睡眠质量、日间嗜睡和失眠。疲劳评估量表(FAS)和爱丁堡产后抑郁量表(EPDS)用于测量疲劳和抑郁。结构有效性通过验证性因子分析(CFA)进行评估。同时使用二元相关分析评估同时效和收敛效度。通过比较不同组之间的 SHI-C 评分来评估已知组的有效性。使用 Cronbach's α 评估可靠性。
平均样本年龄为 30.6 岁,SHI-C 的平均得分为 86.4(SD 8.2)。根据 PSQI、ISI 和 ESS,分别有 43.6%、32.2%和 26.9%的人睡眠质量差、失眠和日间嗜睡过多。SHI-C 总分和睡眠质量子指数得分与 PSQI(r=-0.542,p<0.01;r=-0.648,p<0.01)和 ISI(r=-0.692,p<0.01;r=-0.752,p<0.01)具有中度至强相关性。SHI-C 总分和睡眠质量子指数得分与 ESS、FAS 和 EPDS 显著相关(r=-0.171 至 -0.276;p<0.01)。SHI-C 总分在妊娠中期和工作、从不喝咖啡或每天小睡的人群中较高。SHI-C 总分和睡眠质量子指数的 Cronbach's α 分别为 0.723 和 0.806,睡眠持续时间和睡眠障碍子指数的 Cronbach's α 分别为 0.594 和 0.545。
总体而言,SHI-C 在我国孕妇人群中具有良好的有效性和可接受的可靠性。它可以成为评估睡眠健康的有用工具。需要进一步的研究来完善睡眠持续时间和睡眠障碍子指数。
使用 SHI-C 将有助于评估孕妇的睡眠健康状况,从而有助于促进围产期护理。
