Sleep quality in medical students can be influenced by numerous factors including life events, resilience, and cognitive emotion regulation strategies. Understanding the interplay between these factors is crucial for developing effective interventions to enhance medical students' mental health and well-being.
This study examined the association between life events and sleep quality and explored the mediating roles of resilience and cognitive emotion regulation in this relationship.
This cross-sectional study included 407 medical students from a university in Central Province, China, surveyed between March 15 and March 20, 2023. We employed the Adolescent Self-Rating Life Events Checklist, the Connor-Davidson Resilience Scale, the Cognitive Emotion Regulation Questionnaire, and the Pittsburgh Sleep Quality Index to assess variables. Data analysis involved descriptive statistics, Pearson correlation, and mediation analysis using the SPSS macro Process.
The valid participants (N = 407) were from a medical university with a gender distribution of 29.5% male and 70.5% female. Our findings indicate that higher scores on negative life events significantly predict poorer sleep quality. Furthermore, maladaptive cognitive emotion regulation was also a predictor of poor sleep quality, while resilience was positively associated with beneficial cognitive emotion regulation strategies. Notably, resilience and maladaptive cognitive emotion regulation partially mediated the impact of life events on sleep quality.
The study highlights that life events significantly affect medical students' sleep quality both directly and indirectly through mechanisms involving resilience and cognitive emotion regulation. These insights are vital for framing interventions to improve psychological resilience and adaptive emotion regulation strategies, thereby enhancing sleep quality and overall mental health in medical students. This research contributes to a deeper understanding of how life events impact sleep quality, offering pathways and conditions that could be targeted in future interventions.
医学生的睡眠质量会受到多种因素的影响，包括生活事件、心理韧性和认知情绪调节策略。了解这些因素之间的相互作用对于制定有效的干预措施以促进医学生的心理健康和幸福感至关重要。
本研究考察了生活事件与睡眠质量之间的关联，并探讨了心理韧性和认知情绪调节在这种关系中的中介作用。
这项横断面研究纳入了来自中国中部某省一所大学的407名医学生，于2023年3月15日至3月20日进行调查。我们使用青少年自评生活事件量表、康纳-戴维森心理韧性量表、认知情绪调节问卷和匹兹堡睡眠质量指数来评估变量。数据分析包括描述性统计、Pearson相关性分析以及使用SPSS宏程序Process进行中介分析。
有效参与者（N = 407）来自一所医科大学，性别分布为男性29.5%，女性70.5%。我们的研究结果表明，负面生活事件得分越高，显著预示着睡眠质量越差。此外，适应不良的认知情绪调节也是睡眠质量差的一个预测因素，而心理韧性与有益的认知情绪调节策略呈正相关。值得注意的是，心理韧性和适应不良的认知情绪调节部分介导了生活事件对睡眠质量的影响。
该研究强调，生活事件通过涉及心理韧性和认知情绪调节的机制直接和间接地显著影响医学生的睡眠质量。这些见解对于制定干预措施以提高心理韧性和适应性情绪调节策略至关重要，从而改善医学生的睡眠质量和整体心理健康。本研究有助于更深入地理解生活事件如何影响睡眠质量，为未来干预措施提供了可针对的途径和条件。
