行为类型与睡眠拖延行为的关系：压力知觉的中介作用
The Relationship between Behavioral Types and Sleep-Delaying Behaviors: Mediating the Perception of Stress

目的：调查不同行为类型研究生的睡眠拖延情况，以及压力知觉的中介效应，为改善研究生群体睡眠拖延问题及教育疏导工作提供科学依据。方法：采用A型行为类型评定量表(TABP)、中文版压力知觉量表(CPSS)、中文版睡眠拖延行为量表(CBPS)对596名在校研究生进行问卷调查，使用SPSS 27.0进行统计分析。结果：不同性别研究生的行为类型、压力知觉及睡眠拖延情况的差异无统计学意义(p > 0.05)；班委与非班委研究生的压力知觉及睡眠拖延情况的差异有统计学意义(p < 0.05)，且班委的压力知觉及睡眠拖延的严重程度小于非班委同学。A型行为类型研究生在压力知觉、睡眠拖延上的得分均高于B型行为类型研究生(p < 0.01)。行为类型、压力知觉、睡眠拖延三者两两之间存在相关，压力知觉在行为类型与睡眠拖延行为之间起完全中介作用。结论：行为类型得分能够显著地正向预测压力知觉水平，压力知觉水平能够显著地正向预测睡眠拖延行为水平，压力知觉在行为类型对睡眠拖延行为的影响中起完全中介作用；未来可基于行为类型、压力知觉方面为睡眠拖延行为的干预制定相应的预防和干预措施。
Objective: This study aims to explore the mediating effect of stress perception on sleep procrastination among graduate students with different behavior types, and to provide a scientific basis for addressing sleep procrastination in this population. Methods: A total of 596 graduate students were assessed using the Type A Behavior Rating Scale (TABP), Chinese version of Stress Perception Scale (CPSS), and Chinese version of Sleep Procrastination Behavior Scale (CBPS). Statistical analysis was conducted using SPSS 27.0. Results: No significant differences were found in behavior type, stress perception, and sleep delay between genders (p > 0.05). However, there was a statistically significant difference in stress perception and sleep delay between class committee and non-class committee students (p < 0.05), with class committee students exhibiting lower levels of stress perception and sleep delay than their non-class committee counterparts. Additionally, type A students scored higher on both stress perception and sleep delay compared to type B students (p < 0.01). Behavior type, stress perception, and sleep procrastination were found to be correlated, with stress perception playing a complete mediating role between behavior type and sleep procrastination behavior. Conclusion: The score of behavior type can significantly positively predict the perceived level of stress; similarly, the perceived level of stress can significantly positively predict the level of sleep procrastination behavior; moreover, perceived pressure plays a completely mediating role in influencing behavior type on sleep procrastination behavior. In the future, appropriate prevention and intervention measures can be developed based on behavioral types and stress perceptions for addressing delayed sleeping behaviors.
