Abstract

BackgroundCurrent understanding of the associations between adolescents' daily sleep and daytime alertness and fatigue under naturalistically occurring restricted (school) and unrestricted (vacation) sleep opportunities is limited.MethodsA convenience sample of adolescents (n = 205; 54.1% females, Mage ± SD = 16.9 ± 0.87 years) completed daily measures of sleep, alertness, and fatigue over 28 days (2 weeks during school, and the subsequent 2‐week vacation). Actigraphy and sleep diary total sleep time (TST) and sleep efficiency (SE) were measured. Participants self‐reported sleepiness and fatigue every morning and afternoon, and completed a tablet‐based, 3.2‐min psychomotor vigilance task (PVT) every afternoon. Cross‐lagged multilevel models tested daily TST and SE as predictors of next‐day subjective sleepiness/fatigue and PVT performance. Between‐ (i.e., differences between individuals) and within‐person associations (i.e., whether nights with higher‐than‐individual's‐average TST/SE, predict next‐day outcomes) were tested simultaneously. Covariates included previous‐day outcome, day of the week, study day (1–28), school/vacation, chronotype, and sociodemographic variables.ResultsWithin‐persons, higher‐than‐average TST and SE (both actigraphy and diary) predicted better next‐day PVT performance (all p ≤ .006), and lower subjective sleepiness and fatigue the following morning and afternoon (all p ≤ .032). Between‐persons, adolescents with higher overall diary SE had lower morning subjective sleepiness (p < .001) and fewer PVT false starts in the afternoon (p = 0.02).ConclusionsNights with longer‐ and higher‐than‐average sleep efficiency (both actigraphy and diary) predicted better daytime alertness and fatigue, both when examined objectively via sustained attention and via self‐report. These findings are relevant for understanding the significance of sleep for adolescents' day‐to‐day alertness levels and fatigue, particularly in the context of classroom learning and road safety.

青少年睡眠的日常波动预测第二天的注意力、嗜睡和疲劳：一项为期28天的生态瞬时评估研究

背景目前对青少年在自然发生的受限（学校）和无限制（假期）睡眠机会下的日常睡眠与白天警觉性和疲劳之间关系的理解是有限的。方法采用方便抽样法(n = 205；54.1%的女性（年龄±SD = 16.9±0.87岁）在28天内（2周在校期间和随后的2周假期）完成了每天的睡眠、警觉性和疲劳测量。测量活动记录仪和睡眠日记的总睡眠时间（TST）和睡眠效率（SE）。参与者每天早上和下午自我报告困倦和疲劳，并每天下午完成一项基于平板电脑的3.2分钟精神运动警戒任务（PVT）。交叉滞后的多水平模型测试了每日TST和SE作为第二天主观嗜睡/疲劳和PVT表现的预测因子。同时测试了人与人之间（即个体之间的差异）和人与人之间的关联（即，TST/SE高于个体平均水平的夜晚是否可以预测第二天的结果）。协变量包括前一天的结果、一周中的哪一天、学习日（1-28日）、学校/假期、睡眠类型和社会人口变量。结果在受试者中，高于平均水平的TST和SE（包括活动记录和日记）预示着第二天更好的PVT表现（均p≤0.006），以及第二天上午和下午更低的主观嗜睡和疲劳（均p≤0.032）。在受试者之间，总体日记SE较高的青少年早晨主观困倦程度较低(p <；.001)，下午PVT误启动较少（p = 0.02）。结论：在通过持续注意力和自我报告进行客观检验时，睡眠效率（包括活动记录仪和日记）高于平均水平的夜晚预示着白天的警觉性和疲劳度更好。这些发现有助于理解睡眠对青少年日常警觉性水平和疲劳的重要性，特别是在课堂学习和道路安全的背景下。

期刊介绍： The Journal of Child Psychology and Psychiatry (JCPP) is a highly regarded international publication that focuses on the fields of child and adolescent psychology and psychiatry. It is recognized for publishing top-tier, clinically relevant research across various disciplines related to these areas. JCPP has a broad global readership and covers a diverse range of topics, including: Epidemiology: Studies on the prevalence and distribution of mental health issues in children and adolescents. Diagnosis: Research on the identification and classification of childhood disorders. Treatments: Psychotherapeutic and psychopharmacological interventions for child and adolescent mental health. Behavior and Cognition: Studies on the behavioral and cognitive aspects of childhood disorders. Neuroscience and Neurobiology: Research on the neural and biological underpinnings of child mental health. Genetics: Genetic factors contributing to the development of childhood disorders. JCPP serves as a platform for integrating empirical research, clinical studies, and high-quality reviews from diverse perspectives, theoretical viewpoints, and disciplines. This interdisciplinary approach is a key feature of the journal, as it fosters a comprehensive understanding of child and adolescent mental health. The Journal of Child Psychology and Psychiatry is published 12 times a year and is affiliated with the Association for Child and Adolescent Mental Health (ACAMH), which supports the journal's mission to advance knowledge and practice in the field of child and adolescent mental health.
