Abstract：
This longitudinal study explored the impact of the upper limit of cognitive control on the sleep quality of high school students. We collected data in two waves to examine four main variables: capacity of cognitive control (CCC), trait mindfulness, emotional distress and sleep quality. At the first time point (T1), trait mindfulness and emotional distress were measured by rating scales, and the CCC was evaluated by revised backward masking majority function task. Sleep quality was rated 5 months later (T2). The results indicated that: (1) the CCC was negatively correlated with trait mindfulness, and trait mindfulness was negatively correlated with emotional stress; (2) there was no simple mediation of either trait mindfulness or emotional distress in the relationship between CCC and sleep quality; (3) instead, the CCC was associated with poor sleep quality in a sequential mediation through trait mindfulness and then emotional stress. The research highlights the importance of trait mindfulness and emotional distress for addressing sleep problems in adolescents.
摘要：
这项纵向研究探讨了认知控制上限对高中生睡眠质量的影响。我们收集了两个波的数据来检查四个主要变量：认知控制能力(CCC)，特质正念，情绪困扰和睡眠质量。在第一时间点(T1),特质正念和情绪困扰是通过评定量表来衡量的，并通过修订后向掩蔽多数函数任务对CCC进行了评估。5个月后（T2）对睡眠质量进行评级。结果表明:(1)CCC与特质正念呈负相关,和特质正念与情绪压力呈负相关；（2）在CCC与睡眠质量之间的关系中，没有特质正念或情绪困扰的简单中介作用；（3）相反，在通过特质正念和情绪压力进行的顺序调解中,CCC与睡眠质量差相关.该研究强调了特质正念和情绪困扰对于解决青少年睡眠问题的重要性。
