Mind wandering refers to task-unrelated thoughts that can interfere with ongoing tasks and could be sleep-driven across childhood. The present study investigated the mechanisms of the association between early adolescents' sleep and mind wandering with emotional symptoms and executive function as potential mediators. A total of 257 early adolescents (baseline aged 9–13 years old; 131 boys) completed the questionnaires consisting of the Pittsburgh Sleep Quality Index, mind wandering, depression and anxiety symptoms, and executive function. Cross-sectional and longitudinal data revealed a sequential mediation pathway of emotional symptoms and executive function in the association between sleep and mind wandering. The mediating effect of emotional symptoms in the link between sleep quality and mind wandering was significant among boys but not girls.

睡眠对青少年早期走神的同时和纵向影响

走神是指与任务无关的想法，这些想法可能会干扰正在进行的任务，并且可能在整个童年时期受到睡眠驱动。本研究调查了青少年早期睡眠和走神与情绪症状和执行功能作为潜在中介因素之间的关联机制。共有 257 名青少年早期（基线年龄 9-13 岁；131 名男孩）完成了包括匹兹堡睡眠质量指数、走神、抑郁和焦虑症状以及执行功能在内的调查问卷。横断面和纵向数据揭示了睡眠和走神之间关联的情绪症状和执行功能的顺序中介途径。
