The current study used daily assessments of sleep to examine stability and change in sleep chronotype in adolescents and their parents. The study assessed adolescent sleep chronotype according to age, gender, and parent chronotype, and evaluated its associations with emotional and behavioral problems in youth. Participants included of 417 Mexican American adolescents (Mage = 16.0 years, Range = 13.9-20.0) and 403 caregivers, who reported bed and wake times daily for 2 consecutive weeks at two time points spaced 1 year apart. In addition, adolescents completed established self-report questionnaires of emotional and behavioral problems. Chronotype was computed as the midsleep point from bed to wake time on free days, correcting for sleep debt accumulated across scheduled days. Multilevel modeling showed a curvilinear association between adolescent age and chronotype, with a peak eveningness observed between ages 16 to 17. Adolescent and parent chronotypes were contemporaneously correlated, but each was only moderately stable over the 1-year period. Later adolescent chronotype was contemporaneously associated with more substance use in all adolescents. Individual development and the family context shape sleep chronotype in adolescents and parents. Sleep chronotype is implicated in adolescent behavioral health.
本研究采用每日睡眠评估来考察青少年及其父母的睡眠时型稳定性和变化。该研究根据年龄、性别和父母时型评估了青少年的睡眠时型，并评估了其与青少年情绪和行为问题的关系。参与者包括 417 名墨西哥裔美国青少年（平均年龄=16.0 岁，范围=13.9-20.0）和 403 名照顾者，他们在两年的时间间隔内，每隔一年两次连续两周每天报告睡眠时间和起床时间。此外，青少年还完成了情绪和行为问题的既定自我报告问卷。时型通过从床上到起床时间的中间睡眠点来计算，在考虑到预定日子中积累的睡眠债务后进行了修正。多层次模型显示，青少年年龄与时型之间存在曲线关系，在 16 至 17 岁之间观察到峰值晚型。青少年和父母的时型具有同时相关性，但在 1 年期间仅具有中等稳定性。青少年后期的时型与所有青少年的更多物质使用有关。个体发展和家庭环境塑造了青少年和父母的睡眠时型。睡眠时型与青少年的行为健康有关。
