A chronotype is a designation for individual preference of times for different activities in humans. In chronobiological research, it can be measured in many ways, including subjective questionnaires. The most frequently used questionnaires for determining the chronotype are Morningness-Eveningness Questionnaire (MEQ) and Munich Chronotype Questionnaire (MCTQ). Many studies from around the world have already reported metric properties of the MEQ and MCTQ and their relationship in different languages. In this study, we created the Czech version of the MCTQ and examined its relationship with the Czech version of MEQ, including socio-demographic effects. We also examined the ability of the MCTQ to identify chronotypes and cutoffs for their determination. In total, 2703 people (1964 females, 739 males, 18-75 years of age) were screened by the MEQ, MCTQ and reported on age, sex and self-declared body mass index (BMI). We found a significant relationship ( < .001) between MEQ and MCTQ (MSFsc score, used as a chronotype indicator). No significant sex differences in MEQ and in MSFsc were found, but the relationship between age and MSFsc (mid-sleep on free days corrected for sleep debt on weekdays) ( < .001), MEQ ( < .001), social jet-lag (SJL, < .001) and BMI ( < .001) were found. The SJL was related to MSFsc ( < .001), MEQ ( < .001) and BMI ( < .05). The optimal cutoff value of MSFsc to identify morning and evening chronotype was 3.35 and 4.6, respectively. The results of this study support the mutual substitutability of the Czech version of MEQ and MCTQ.
时型是指个体在不同活动中对时间偏好的一种指定。在生理时生物学研究中，可以通过多种方式进行测量，包括主观问卷。用于确定时型的最常用问卷包括 Morningness-Eveningness Questionnaire (MEQ) 和 Munich Chronotype Questionnaire (MCTQ)。来自世界各地的许多研究已经报告了 MEQ 和 MCTQ 的度量特性及其在不同语言中的关系。在这项研究中，我们创建了捷克语版的 MCTQ，并研究了它与捷克语版 MEQ 的关系，包括社会人口统计学的影响。我们还研究了 MCTQ 识别时型的能力及其确定的截止值。总共有 2703 人（1964 名女性，739 名男性，年龄 18-75 岁）通过 MEQ、MCTQ 进行筛选，并报告了年龄、性别和自我报告的体重指数（BMI）。我们发现 MEQ 和 MCTQ 之间存在显著关系（ < 0.001）（MSFsc 评分，用作时型指标）。MEQ 和 MSFsc 之间未发现显著的性别差异，但年龄与 MSFsc（工作日睡眠债务校正后的周末自由日的睡眠中点）（ < 0.001）、MEQ（ < 0.001）、社会时差（SJL， < 0.001）和 BMI（ < 0.001）之间存在关系。SJL 与 MSFsc（ < 0.001）、MEQ（ < 0.001）和 BMI（ < 0.05）有关。MSFsc 识别晨型和晚型的最佳截止值分别为 3.35 和 4.6。这项研究的结果支持捷克语版 MEQ 和 MCTQ 的相互替代性。
