• Abstract: Objective: To explore the impact of problematic social media use on sleep procrastination among college students and its underlying mechanisms, examine the chain mediating role of mindfulness and ego depletion, and verify the intervention effect of mindfulness training, so as to provide theoretical and practical basis for improving college students’ sleep procrastination. Methods: Study 1 adopted a questionnaire survey method to measure problematic social media use, mindfulness, ego depletion, and sleep procrastination among 680 college students, and tested the relationships between variables through statistical analysis. Study 2 selected 40 college students with high levels of problematic social media use and sleep procrastination, randomly divided them into an experimental group (receiving 8-week mindfulness intervention) and a control group (without intervention), and evaluated the effect through pre-test and post-test. Results: Study 1 showed that problematic social media use significantly and positively predicted sleep procrastination (β=0.12, p<0.001). Mindfulness (β=-0.16, p<0.001) and ego depletion (β=0.24, p<0.001) played independent mediating roles respectively, and their chain mediating effect was significant (effect value=0.01, 95% CI=[0.002, 0.01]). Study 2 showed that in the experimental group, the level of mindfulness significantly increased (t=-8.77, p<0.001), while ego depletion (t=6.29, p<0.001) and sleep procrastination (t=4.21, p<0.001) significantly decreased, with no significant changes in the control group. Conclusion: Problematic social media use indirectly leads to sleep procrastination by reducing mindfulness and exacerbating ego depletion. Mindfulness training can effectively improve this path, providing a scientific basis and practical plan for college students’ sleep health management. 目的：探讨问题性社交媒体使用对大学生睡眠拖延的影响及内在机制，考察正念与自我损耗的链式中介作用，并验证正念训练的干预效果，为改善大学生睡眠拖延提供理论与实践依据。方法：研究一采用问卷调查法，对680名大学生测量问题性社交媒体使用、正念、自我损耗及睡眠拖延水平，通过统计分析检验变量关系；研究二选取40名高问题性社交媒体使用和高睡眠拖延的大学生，随机分为实验组（接受8周正念干预）与对照组（无干预），通过前后测评估干预效果。结果：研究一显示，问题性社交媒体使用显著正向预测睡眠拖延（β=0.12，p<0.001）；正念（β=-0.16，p<0.001）与自我损耗（β=0.24，p<0.001）起独立中介作用，且二者的链式中介效应显著（效应值=0.01，95%CI=［0.002，0.01］）。研究二显示，实验组正念水平显著提升（t=-8.77，p<0.001），自我损耗（t=6.29，p<0.001）及睡眠拖延（t=4.21，p<0.001）水平显著降低，对照组无显著变化。结论：问题性社交媒体使用通过降低正念水平、加剧自我损耗间接导致睡眠拖延，正念训练可有效改善该影响路径，为大学生睡眠健康管理提供科学依据与实操方案。
