ABSTRACT

This paper examined the psychometric properties of the French version of the Children’s Chronotype Questionnaire (CCTQ) attending two elementary schools in Luxembourg (n = 172; ages 4–11 years, M = 8.0, SD = 2.1) of either Portuguese (n = 11), Luxembourgian (n = 147), or other (n = 15) ethnicity. Parents completed the CCTQ, from which we used two chronotype scales (i.e. midsleep point on free days; MSF, multi-item morningness/eveningness; M/E). Results indicated satisfactory internal consistency for M/E scale (α = .70), with high intercorrelation scores (r = .91 between items; r = .87 between scales). As hypothesized, the chronotype of morning and evening type children were different (p= .017, η2 = .06), with the former having an earlier MSF (M = 5:29 h) compared with the latter (M = 5:48 h). The evening group showing the poorest outcomes for the qualitative grades (2014/2015: F(7.308) = 2.34, p = .002; 2015/2016: F(7.996) = 2.46, p = .001). No significant differences in MSFc were found between natives and immigrants. The results indicate that the French version of the CCTQ has adequate reliability and validity for research studies. Evaluating chronotype and sleep behaviors in preschool and school-age children is important, as both may have a negative impact on academic performance.

摘要

本文研究了在卢森堡两所小学（n = 172；年龄 4-11 岁，M = 8.0，SD = 2.1）和葡萄牙语（n = 11 )、卢森堡人 (n = 147) 或其他 (n = 15) 种族。父母完成了 CCTQ，我们从中使用了两个时间型量表（即空闲日的睡眠中期；MSF，多项目早晨/晚上；M/E）。结果表明，M/E 量表的内部一致性令人满意（α = .70），相关性得分高（项目之间的r = .91；量表之间的r = .87）。如假设，早晚型儿童的表型不同（p= .017, η2 = .06)，前者的 MSF (M = 5:29 h) 比后者 (M = 5:48 h) 早。晚上组的定性成绩表现最差（2014/2015：F(7.308) = 2.34，p = .002；2015/2016：F(7.996) = 2.46，p = .001）。本地人和移民之间的 MSFc 没有显着差异。结果表明，法语版的 CCTQ 对研究具有足够的信度和效度。评估学龄前和学龄儿童的表型和睡眠行为很重要，因为两者都可能对学业成绩产生负面影响。
