摘要：Sleep disturbances are prevalent within the global college student population, with rumination being a significant cognitive determinant of sleep health. Nonetheless, the reciprocal and dynamic relationship between these two factors has not been investigated. This study employed an intensive longitudinal design in which self-report data were collected over 21 days from 417 Chinese college students (76.0% women; Mage = 18.28 years, SD = 0.90). Results of dynamic structural equation modeling (DSEM) revealed temporal stability in sleep quality, bedtime procrastination, and rumination. Poor sleep quality predicted subsequent rumination, and vice versa, creating a cycle of mutual exacerbation. Bedtime procrastination and rumination showed a similar bidirectional pattern. These findings provide the first longitudinal evidence of a dynamic, reciprocal cycle between rumination and sleep health among college students, revealing real-time mechanisms of mutual reinforcement. This study underscores the need for integrative interventions that concurrently address cognitive (rumination), behavioral (bedtime procrastination), and physiological (sleep quality) factors to effectively disrupt the self-reinforcing cycle.全球大学生群体中睡眠障碍十分普遍，而反刍是影响睡眠健康的重要认知因素。然而，这两者之间相互作用的动态关系尚未得到研究。本研究采用密集追踪设计，对417名中国大学生（76.0%为女性；平均年龄18.28岁，标准差0.90）进行了为期21天的自报数据收集。通过动态结构方程模型（DSEM）分析结果显示，睡眠质量、睡前拖延和反刍在时间上保持稳定，即有显著的自回归效应。睡眠质量差会后续的反刍，反之亦然，形成相互加剧的循环。睡前拖延和反复思考也表现出相似的双向模式。这些发现首次提供了关于大学生反刍与睡眠健康之间动态、相互强化的实时机制。本研究强调，需要采取同时针对认知（反刍）、行为（睡前拖延）和生理（睡眠质量）因素的综合干预措施，才能有效打破自我强化的循环。
