Sleep quality can affect the physical and mental health, as well as the personal development of college students. Mindfulness practices are known to ameliorate sleep disorder and improve sleep quality. Trait mindfulness, an innate capacity often enhanced by mindfulness training, has been shown to relate to better sleep quality and different aspects of psychological well-being. However, how individual difference factors such as trait mindfulness relate to sleep quality remains largely unclear, which limits the optimization and further application of mindfulness-based intervention schemes targeting the improvement of sleep quality. In this study, we aimed to investigate how negative emotions and neuroticism may influence the relationship between trait mindfulness and sleep quality. A conditional process model was built to examine these relationships in 1,423 Chinese young adults. Specifically, the conditional process model was constructed with trait mindfulness as the independent variable, sleep quality as the dependent variable, negative emotions as the mediating variable, and neuroticism as the moderating variable. Our results showed that negative emotions mediated the link between mindfulness and sleep quality and that neuroticism had a moderating effect on the relationship between mindfulness and sleep quality. Together, these findings suggested a potential mechanism of how trait mindfulness influences sleep quality, provided a therapeutic target for which mindfulness-based interventions may act upon to improve sleep quality, and offered a basis for prediction of different intervention effects among individuals.
睡眠质量会影响大学生的身心健康以及个人发展。正念练习已知可改善睡眠障碍并提高睡眠质量。特质正念是一种常通过正念训练得到增强的内在能力，已被证明与更好的睡眠质量及心理健康的不同方面有关。然而，特质正念等个体差异因素如何与睡眠质量相关仍 largely 不清楚，这限制了以改善睡眠质量为目标的基于正念的干预方案的优化和进一步应用。在本研究中，我们旨在调查负面情绪和神经质如何可能影响特质正念与睡眠质量之间的关系。构建了一个条件过程模型来检验 1423 名中国年轻人中的这些关系。具体而言，条件过程模型以特质正念为自变量，睡眠质量为因变量，负面情绪为中介变量，神经质为调节变量。我们的结果表明，负面情绪介导了正念与睡眠质量之间的联系，并且神经质对正念与睡眠质量之间的关系有调节作用。总之，这些发现揭示了特质正念影响睡眠质量的潜在机制，为基于正念的干预措施可能作用以改善睡眠质量提供了治疗靶点，并为预测个体间不同的干预效果提供了依据。
