This study aimed to develop a Korean version of the Substance Use Sleep Scale (SUSS) and test its validity and reliability in patients with alcohol use disorder.
This study used a methodological design. Exploratory factor analysis and content, construct, and reliability analyses of the SUSS were conducted. Between June and November 2023, 292 patients with alcohol use disorder were recruited from three psychiatric mental hospitals and five community addiction management centers located in five cities in South Korea.
Exploratory factor analysis was conducted on 23 items extracted in the content validity process, and 20 items were selected; the cumulative explanation rate of the scale was 62.79%. The scale had good internal consistency with a Cronbach's α of 0.91. Confirmatory factor analysis demonstrated a reasonable fit for the 4-factors model (χ2=656.95 [p<0.001], χ2/df=2.29, standardized root mean-squared residual=0.06, root mean square error of approximation=0.062, Tucker-Lewis index=0.92, comparative fit index=0.92, incremental fit index=0.92).
The findings suggest that the Korean version of the SUSS is a valid and reliable scale with a robust factorial structure and is useful for measuring sleep problems in patients with alcohol use disorder.
本研究旨在开发物质使用睡眠量表（SUSS）的韩语版本，并在酒精使用障碍患者中测试其有效性和可靠性。
本研究采用方法学设计。对SUSS进行探索性因素分析以及内容、结构和可靠性分析。2023年6月至11月，从韩国五个城市的三家精神心理医院和五个社区成瘾管理中心招募了292名酒精使用障碍患者。
对在内容效度过程中提取的23个项目进行探索性因素分析，选择了20个项目；量表的累积解释率为62.79%。量表具有良好的内部一致性，克朗巴赫α系数为0.91。验证性因素分析表明四因素模型拟合合理（χ2 = 656.95 [p < 0.001]，χ2/df = 2.29，标准化残差均方根 = 0.06，近似误差均方根 = 0.062，塔克-刘易斯指数 = 0.92，比较拟合指数 = 0.92，增值拟合指数 = 0.92）。
研究结果表明，SUSS韩语版本是一个有效且可靠的量表，具有强大的因子结构，可用于测量酒精使用障碍患者的睡眠问题。
