Given the impact of sleep in several domains of a child's development, the comparison between actigraphy and parental questionnaires is of great importance in preschool-aged children, an understudied group. While parental reports tend to overestimate sleep duration, actigraphy boosts the frequency of night-waking's. Our primary goal was to compare actigraphy data and parental reports (, CSHQ), regarding bedtime, wake-up time, sleep duration, and wake after sleep onset (WASO), using the Bland-Altman technique. Forty-six children, age 3-6 years, and their parents participated. Results suggest that, despite existing associations between sleep schedule variables measured by both methods (from = 0.57 regarding bedtime at weekends to = 0.86 regarding wake-up time during the week, ), differences between them were significant and agreements were weak, with parents overestimating bedtimes and wake-up times in relation to actigraphy. Differences between actigraphy and CSHQ were ± 52 min for weekly bedtime, ± 38 min for weekly wake-up time, ±159 min for total sleep time, and ± 62 min for WASO, indicating unsatisfactory agreement between methods. Correlations between actigraphy data and CSHQ dimensions are also explored. Our study contributes to the knowledge of the characteristics of each instrument, along with their tendency to overestimate and underestimate certain sleep parameters. We conclude that a complementary use of both instruments would better inform clinical practice and research on a child's sleep.
鉴于睡眠对儿童发育多个领域的影响，对于学龄前儿童（一个研究较少的群体）而言，活动记录仪与家长问卷之间的比较非常重要。虽然家长报告往往会高估睡眠时间，但活动记录仪会增加夜间醒来的频率。我们的主要目标是使用Bland-Altman技术，比较活动记录仪数据与家长报告（儿童睡眠习惯问卷，CSHQ）在就寝时间、起床时间、睡眠时间和睡眠开始后觉醒时间（WASO）方面的差异。46名3至6岁的儿童及其家长参与了研究。结果表明，尽管两种方法测量的睡眠时间表变量之间存在相关性（从周末就寝时间的r = 0.57到工作日起床时间的r = 0.86），但它们之间的差异显著且一致性较弱，家长相对于活动记录仪高估了就寝时间和起床时间。活动记录仪与CSHQ之间的差异为：每周就寝时间±52分钟，每周起床时间±38分钟，总睡眠时间±159分钟，WASO±62分钟，表明两种方法之间的一致性不令人满意。同时还探讨了活动记录仪数据与CSHQ维度之间的相关性。我们的研究有助于了解每种工具的特点，以及它们高估和低估某些睡眠参数的倾向。我们得出结论，两种工具的互补使用将为儿童睡眠的临床实践和研究提供更好的信息。
