目的:探讨睡眠拖延和自我控制在压力知觉和大学生手机依赖间的链式中介作用机制。方法:采用手机依赖指数量表、中国压力知觉量表、睡眠拖延量表和自我控制量表对安徽省399名大学生进行调查。结果:(1) 自我控制与压力知觉、睡眠拖延、手机依赖负相关显著,压力知觉、睡眠拖延、手机依赖两两间显著正相关。(2) 中介作用检验结果表明,压力知觉可以通过睡眠拖延和自我控制的独立中介及其链式中介间接对手机依赖产生影响。结论:睡眠拖延和自我控制在压力知觉和大学生手机依赖中起链式中介作用,这为预防大学生手机依赖提供一定理论依据与启示。Objective: To explore the chain mediated mechanism of sleep procrastination and self-control in the relationship between perceived stress and college students’ dependence on mobile phones. Method: A survey was conducted on 399 college students in Anhui Province using the Mobile Phone Dependence Index Scale, Chinese Stress Perception Scale, Sleep Delay Scale, and Self Control Scale. Result: (1) There is a significant negative correlation between self-control and perceived stress, sleep procrastination, and phone dependence, while there is a significant positive correlation between perceived stress, sleep procrastination, and phone dependence. (2) The results of the mediation test indicate that perceived stress can indirectly affect mobile phone dependence through the independent mediation of sleep procrastination and self-control, as well as their chain mediation. Conclusion: Sleep procrastination and self-control play a chain mediated role in stress perception and college students’ mobile phone dependence, providing a theoretical basis and inspiration for preventing college students’ mobile phone dependence.
