数字化媒体使用对大学生睡眠质量的影响：负性情绪的中介作用

The Impact of Digital Media Use on Sleep Quality among College Students: The Mediating Role of Negative Emotions

摘要: 目的：探讨大学生数字媒体使用与睡眠质量的关系，以及负性情绪在其中的中介作用。方法：采用数字媒体使用行为量表、抑郁–焦虑–压力量表(DASS-21)以及匹兹堡睡眠质量指数量表(PSQI)对531名大学生进行问卷调查。结果：(1) 数字媒体使用、睡眠质量与负性情绪两两之间均呈显著正相关。(2) 负性情绪在数字媒体使用行为与睡眠质量之间起部分中介作用，中介效应占总效应的27.17%。结论：数字媒体使用与大学生睡眠质量之间存在正相关关系，负性情绪在其中起部分中介作用。数字媒体使用不仅直接与睡眠质量下降相关联，还可能通过伴随的负性情绪间接影响睡眠质量。这一发现描述了“数字媒体使用–情绪状态–睡眠质量”之间的关联模式，为高校在数字化时代开展睡眠健康干预提供了初步的实证参考。

Abstract: Objective: To explore the relationship between digital media use and sleep quality among college students, as well as the mediating role of negative emotions in this relationship. Methods: A questionnaire survey was conducted among 531 college students using the Digital Media Use Behavior Scale, the Depression-Anxiety-Stress Scale (DASS-21), and the Pittsburgh Sleep Quality Index (PSQI). Results: (1) There were significant positive correlations between digital media use, sleep quality, and negative emotions. (2) Negative emotions partially mediated the relationship between digital media use behavior and sleep quality, with the mediating effect accounting for 27.17% of the total effect. Conclusion: There is a positive correlation between digital media use and sleep quality among college students, with negative emotions playing a partial mediating role. Digital media use is not only directly associated with poor sleep quality but may also indirectly affect sleep quality through accompanying negative emotions. This finding delineates the association pattern of “digital media use-emotional state-sleep quality,” providing preliminary empirical evidence to support sleep health interventions in universities in the digital age.
