Chronotype refers to individual differences in the circadian phase that affect a person's biological and psychological functioning. One of the most useful tools for measuring chronotype in children aged 4 - 11 years is the Children's Chronotype Questionnaire (CCTQ). Therefore, due to the importance of measuring chronotype in children and also the lack of a standard scale in Iran, this study aimed to examine the reliability and validity of the Persian version of this questionnaire for children. The participants of this cross-sectional study were 272 Iranian children aged five to eleven years with their parents, selected by convenience sampling method. To collect data, all participants completed the CCTQ and the Children's Sleep Habits Questionnaire (CSHQ), which were examined by the researchers for their construct and concurrent validity. Over a period of three weeks, 50 mothers participated in a test of the test-retest reliability of the CCTQ. During this time, their sleep patterns were monitored using a sleep diary to test for reliability. The Cronbach's alpha of the CCTQ-M/E was 0.71. Test-retest reliability using the Spearman correlation coefficient between two observations with an interval of three weeks was 0.83. The MSFsc index was significantly correlated with M/E, CT, and most of the parent-reported sleep/wake parameters. In addition, the three indicators of the CCTQ were significantly associated with most of the sleep/wake parameters of the sleep diary and the components of the CSHQ. The Persian version of the CCTQ has desirable psychometric properties for the assessment of chronotype in five- to eleven-year-old children.
昼夜节律类型是指昼夜节律阶段的个体差异，它会影响一个人的生理和心理功能。对于4至11岁儿童而言，测量昼夜节律类型最有用的工具之一是儿童昼夜节律问卷（CCTQ）。因此，鉴于测量儿童昼夜节律类型的重要性以及伊朗缺乏标准量表，本研究旨在检验该问卷波斯语版本对儿童的信效度。这项横断面研究的参与者是272名年龄在5至11岁的伊朗儿童及其父母，采用方便抽样法选取。为收集数据，所有参与者都完成了CCTQ和儿童睡眠习惯问卷（CSHQ），研究人员对其结构效度和同时效度进行了检验。在三周的时间里，50位母亲参与了CCTQ重测信度测试。在此期间，通过睡眠日记监测她们的睡眠模式以测试信度。CCTQ-M/E的克朗巴哈系数为0.71。使用间隔三周的两次观察结果之间的斯皮尔曼相关系数得出的重测信度为0.83。MSFsc指数与M/E、CT以及大多数家长报告的睡眠/觉醒参数显著相关。此外，CCTQ的三个指标与睡眠日记的大多数睡眠/觉醒参数以及CSHQ的组成部分显著相关。CCTQ的波斯语版本在评估5至11岁儿童的昼夜节律类型方面具有理想的心理测量学特性。
