心理健康与睡眠拖延行为的关系：自我控制能力的中介作用
The Relationship between Mental Health and Sleep Procrastination: The Mediating Role of Self-Control

目的：探讨心理健康对睡眠拖延行为的影响，以及自我控制的中介效应，为改善青少年睡眠拖延问题提供参考。方法：采用症状自评量表(SCL-90)、自我控制量表(SCS)、睡眠拖延量表(BPS)对西南地区某大学1084名研究生进行问卷调查，使用SPSS25.0统计软件进行统计分析。结果：不同性别研究生的心理健康水平、自我控制能力的差异有统计学意义(p < 0.05)，且男性心理健康水平、自我控制能力高于女性；不同性别研究生的睡眠拖延水平的差异不存在统计学意义(p > 0.05)。独生子女和非独生子女的研究生的心理健康水平、自我控制能力和睡眠拖延水平的差异不存在统计学意义(p > 0.05)。睡眠拖延得分与年级存在显著正向相关。心理健康得分、自我控制得分、睡眠拖延得分三者两两之间存在相关。中介效应结果提示：自我控制能力在心理健康与睡眠拖延行为之间起完全中介作用。结论：心理健康通过中介变量自我控制的作用，进而对睡眠拖延产生影响；未来可基于自我控制能力、心理健康等方面制定更为全面、有效的预防和干预措施。
Objective: To explore the influence of mental health on sleep delay behavior and the mediating effect of self-control, so as to provide reference for improving adolescent sleep delay. Methods: 1084 postgraduates from a university in Southwest China were investigated by Symptom Checklist 90 (SCL-90), Self-control Scale (SCS) and Sleep Delay Scale (BPS). SPSS25.0 statistical software was used for statistical analysis. Results: There were statistically significant differences in mental health level and self-control ability between different genders (p < 0.05), and male’s mental health level and self-control ability were higher than female’s. There was no significant difference in the level of sleep delay between different genders (p > 0.05). There was no significant difference in mental health level, self-control ability and sleep delay level between only child and non-only child graduate students (p > 0.05). There was a significant positive correlation between sleep delay score and grade. There was a pin-to-pin relationship between mental health scores, self-control scores, and sleep procrastination scores. The mediating effect results suggest that self-control plays a complete mediating role between mental health and sleep delay behavior. Conclusion: Mental health has an effect on sleep delay by mediating self-control. In the future, more comprehensive and effective prevention and intervention measures can be developed based on self-control ability and mental health.
