ABSTRACT

Chronotype is an individual characteristic that can be important for health and quality of life. There are currently no instruments to measure chronotype in Ukrainians, so this study was conducted to provide adaptations of questionnaires with proven psychometric properties. The Composite Scale of Morningness (CSM) and the Munich ChronoType Questionnaire (MCTQ) were translated into Ukrainian using the parallel blind method; 776 Ukrainians then completed the questionnaires and answered questions on demographics and substance use. The Ukrainian version of the CSM showed high internal consistency (Cronbach’s alpha = 0.874). Greater morningness (CSM) correlated with earlier midsleep on sleep-corrected free days (MSFsc), r = −0.623. Later chronotypes as derived from both CSM and MCTQ exhibited more pronounced social jetlag and greater consumption of stimulants. In accordance with the assumptions underlying the CSM, confirmatory factor analysis proved the one-factor structure of the Ukrainian version of the questionnaire. The cut-off scores (bottom/top 10%) for the Ukrainian CSM were 23 or less for evening types and 42 or more for morning types. The Ukrainian CSM and MCTQ appear to be psychometrically sound measures of chronotype ready for use in future studies.

摘要

时间型是一种对健康和生活质量很重要的个体特征。目前没有工具可以测量乌克兰人的时间型，因此进行这项研究是为了提供对具有经证实的心理测量特性的问卷的改编。使用平行盲法将早晨综合量表（CSM）和慕尼黑时间类型问卷（MCTQ）翻译成乌克兰语；776 名乌克兰人随后完成了调查问卷并回答了有关人口统计和物质使用的问题。乌克兰语版本的 CSM 表现出高度的内部一致性（Cronbach's alpha = 0.874）。更早的早晨（CSM）与睡眠校正自由日（MSFsc）的早期睡眠相关，r = -0.623。来自 CSM 和 MCTQ 的后期表型表现出更明显的社交时差和更多的兴奋剂消耗。根据 CSM 的假设，验证性因素分析证明了乌克兰版问卷的单因素结构。乌克兰 CSM 的截止分数（底部/顶部 10%）对于晚上类型为 23 或更低，对于早晨类型为 42 或更高。乌克兰的 CSM 和 MCTQ 似乎是心理测量学上可靠的时间型测量方法，可以在未来的研究中使用。
