Environmental and social factors, such as the place of residence, social relations quality, and cell phone addiction, may influence the relationship between sleep quality and quality of life. This study aimed to examine the mediating role of social relations quality and cell phone addiction in the relationship between sleep quality and quality of life among medical students residing in dormitories. In this cross-sectional study, 380 medical students who resided in the university dormitory participated. Pittsburgh Sleep Quality Index (PSQI), WHO Quality-of-Life Scale, Social Relational Quality Scale, and Cell phone Addiction Scale were used. Pearson correlation coefficient and structural equation modeling were used for data analysis through Macro PROCESS SPSS (Model 4). This study indicated that medical students residing in dormitories who experienced better sleep quality and stronger social relations quality reported an enhanced quality of life. The indirect effect of sleep quality on the quality of life was mediated by social relations quality (Effect=-0.09, 95% CI: -0.18 to -0.02). The cell phone addiction did not mediate the effect of sleep quality on the quality of life (Effect=-0.006, 95% CI: -0.04 to 0.02). Given the mediating role of social relations quality in the relationship between sleep quality and quality of life in medical students residing in dormitories, by increasing in quality of sleep using improved quality of social relations led to a better quality of life.
环境和社会因素，如居住地点、社会关系质量和手机成瘾，可能会影响睡眠质量与生活质量之间的关系。本研究旨在探讨社会关系质量和手机成瘾在居住在宿舍的医学生睡眠质量与生活质量关系中的中介作用。在这项横断面研究中，380名居住在大学宿舍的医学生参与其中。使用了匹兹堡睡眠质量指数（PSQI）、世界卫生组织生活质量量表、社会关系质量量表和手机成瘾量表。通过Macro PROCESS SPSS（模型4）使用Pearson相关系数和结构方程模型进行数据分析。本研究表明，居住在宿舍且睡眠质量较好、社会关系质量较强的医学生生活质量更高。睡眠质量对生活质量的间接效应通过社会关系质量介导（效应=-0.09，95%CI：-0.18至-0.02）。手机成瘾并未介导睡眠质量对生活质量的影响（效应=-0.006，95%CI：-0.04至0.02）。鉴于社会关系质量在居住在宿舍的医学生睡眠质量与生活质量关系中的中介作用，通过改善社会关系质量来提高睡眠质量可带来更好的生活质量。
