We developed a Japanese version of RU-SATED (RU-SATED-J), a simple self-rated scale for measurement of multidimensional sleep health, and examined its reliability and psychometric validity.
The RU-SATED-J was developed by a rigorous reverse translation process. It consists of six questions, each with three Likert-type response options. The total score (range 0-12) was calculated by summing the item scores. Psychometric characteristics were tested in an observational cross-sectional study involving factory workers in Japan (n = 177, mean age 42.8 ± 11.6 years, range 19-65 years). The distribution and reliability of the scale scores were examined in terms of Cronbach's alpha coefficient. The convergent and divergent validity of the scale score were assessed by examining the correlations of various factors with the Insomnia Severity Index (ISI) and the Epworth Sleepiness Scale (ESS).
The distribution of scores was left-skewed, with a mean of 8.21 ± 2.72 points, and range of 0-12. The internal reliability of the scale was α = 0.758. The total score showed a significant negative correlation with the ISS (rs = -0.542, P < 0.001) and the ESS (rs = -0.178, P = 0.018). Exploratory factor analysis (EFA) demonstrated a two-factor structure. Confirmatory factor analysis (CFA) showed that the goodness of fit of the higher-order factor model had a Root Mean Square Error of Approximation (RMSEA) of <0.001 and a Comparative Fit Index (CFI) of 1.00, confirming its factorial validity.
The RU-SATED is a promising new instrument for measuring multi-dimensional sleep health perception among Japanese adults. Further general population studies using this Japanese version of the questionnaire should be considered.
我们开发了日语版的RU-SATED（RU-SATED-J），这是一种用于测量多维睡眠健康的简单自评量表，并检验了其信度和心理测量效度。
RU-SATED-J通过严格的反向翻译过程开发而成。它由六个问题组成，每个问题有三个李克特式回答选项。通过对各项目得分求和计算总分（范围为0 - 12分）。在一项涉及日本工厂工人的观察性横断面研究中（n = 177，平均年龄42.8 ± 11.6岁，范围19 - 65岁）测试心理测量特征。根据克朗巴赫α系数检验量表得分的分布和信度。通过检验各种因素与失眠严重程度指数（ISI）和爱泼华嗜睡量表（ESS）的相关性来评估量表得分的收敛效度和区分效度。
得分分布呈左偏态，均值为8.21 ± 2.72分，范围为0 - 12分。量表的内部信度为α = 0.758。总分与ISI（rs = -0.542，P < 0.001）和ESS（rs = -0.178，P = 0.018）呈显著负相关。探索性因素分析（EFA）显示为两因素结构。验证性因素分析（CFA）表明高阶因素模型的拟合优度具有近似均方根误差（RMSEA）<0.001和比较拟合指数（CFI）为1.00，证实了其因素效度。
RU-SATED是一种很有前景的新工具，可用于测量日本成年人对多维睡眠健康的认知。应考虑使用该日语版问卷进行进一步的一般人群研究。
