Sleep habits developed in adolescence shape long-term trajectories of psychological, educational, and physiological well-being. Adolescents' sleep behaviors are shaped by their parents' sleep at both the behavioral and biological levels. In the current study, we sought to examine how neural concordance in resting-state functional connectivity between parent-child dyads is associated with dyadic concordance in sleep duration and adolescents' sleep quality. To this end, we scanned both parents and their child (N=28 parent-child dyads; parent M=42.8years; adolescent M=14.9years; 14.3% father; 46.4% female adolescent) as they each underwent a resting-state scan. Using daily diaries, we also assessed dyadic concordance in sleep duration across two weeks. Our results show that greater daily concordance in sleep behavior is associated with greater neural concordance in default-mode network connectivity between parents and children. Moreover, greater neural and behavioral concordances in sleep is associated with more optimal sleep quality in adolescents. The current findings expand our understanding of dyadic concordance by providing a neurobiological mechanism by which parents and children share daily sleep behaviors.
青少年时期养成的睡眠习惯塑造了心理、教育和生理健康的长期发展轨迹。青少年的睡眠行为在行为和生物学层面上都受到其父母睡眠情况的影响。在本研究中，我们试图探究亲子二元组静息态功能连接中的神经一致性如何与睡眠时间的二元一致性以及青少年的睡眠质量相关联。为此，我们对父母及其子女（N = 28个亲子二元组；父母平均年龄M = 42.8岁；青少年平均年龄M = 14.9岁；14.3%为父亲；46.4%为女性青少年）进行了静息态扫描。我们还通过每日日记评估了两周内睡眠时间的二元一致性。我们的研究结果表明，睡眠行为中更高的每日一致性与父母和孩子默认模式网络连接中更高的神经一致性相关。此外，睡眠方面更高的神经和行为一致性与青少年更优的睡眠质量相关。当前的研究结果通过提供一种父母与孩子共享日常睡眠行为的神经生物学机制，扩展了我们对二元一致性的理解。
