This study aimed to evaluate the reliability and validity of the Korean version of the Mini-Sleep Questionnaire-Insomnia in Korean college students.
A total of 470 students from six nursing colleges in South Korea participated in the study. The translation and linguistic validation of the Mini-Sleep Questionnaire-Insomnia was performed based on guidelines. The Pittsburgh Sleep Quality Index and the Perceived Stress Scale were used to validate the measure. Cronbach α, item-total correlation for internal consistency reliability and intraclass correlation coefficient for test-retest reliability were evaluated. Exploratory factor analysis for construct validity, Pearson's correlation with the Pittsburgh Sleep Quality Index and the Perceived Stress Scale for concurrent validity, and the receiver operating character curve for predictive validity were assessed.
The 4-item Mini-Sleep Questionnaire-Insomnia had a Cronbach α of .69 and the item-total correlations were higher than .30. Cronbach α increased to .73 if the item assessing the use of sleeping pills and tranquilizers was deleted. This item had marked skewness and kurtosis issues. Factor analysis indicated unidimensionality, explaining 53.0% of the total variance. The measure showed high test-retest reliability (i.e., intraclass correlation coefficient = .84), acceptable concurrent validity (r with the Pittsburg Sleep Quality Index = .69; r with the Perceived Stress Scale = .31) and predictive validity [area under curve = .85; 95% confidence interval (0.81, 0.90)].
The Mini-Sleep Questionnaire-Insomnia showed acceptable reliability and validity. Yet, the limited distribution in sleep medications warrants further evaluations in the clinical population.
本研究旨在评估韩语版《迷你睡眠问卷 - 失眠量表》在韩国大学生中的信效度。
韩国六所护理学院的470名学生参与了本研究。《迷你睡眠问卷 - 失眠量表》的翻译及语言验证依据相关指南进行。采用匹兹堡睡眠质量指数和感知压力量表对该量表进行效度验证。评估了内部一致性信度的克朗巴哈α系数、项目 - 总分相关性以及重测信度的组内相关系数。对结构效度进行探索性因子分析，对同时效度采用与匹兹堡睡眠质量指数和感知压力量表的皮尔逊相关性分析，对预测效度采用受试者工作特征曲线分析。
4个条目的《迷你睡眠问卷 - 失眠量表》克朗巴哈α系数为0.69，项目 - 总分相关性高于0.30。若删除评估安眠药和镇静剂使用情况的条目，克朗巴哈α系数增至0.73。该条目存在明显的偏态和峰态问题。因子分析表明具有单维度性，解释了总方差的53.0%。该量表显示出较高的重测信度（即组内相关系数 = 0.84）、可接受的同时效度（与匹兹堡睡眠质量指数的r = 0.69；与感知压力量表的r = 0.31）和预测效度[曲线下面积 = 0.85；95%置信区间(0.81, 0.90)]。
《迷你睡眠问卷 - 失眠量表》显示出可接受的信效度。然而，睡眠药物使用情况分布有限，需要在临床人群中进一步评估。
