BACKGROUND
Numerous studies have linked psychological distress to fatigue, yet few have explored how bedtime media use mediates this relationship. This study examines whether using visual or auditory stimuli at bedtime mediates the relationship between psychological distress and fatigue among college students.
METHODS
A total of 1,831 Chinese college students (927 males and 904 females; mean age = 20.36 years, SD 1.26) from universities in Shaanxi Province, China, participated in the study. Data were collected using an electronic questionnaire that assessed psychological distress, bedtime media use, and fatigue. The bootstrap method was employed to test the mediating effects, with 5,000 random samples and a 95% confidence interval.
RESULTS
Psychological distress ( = 0.256, < 0.001), visual stimuli of bedtime media use ( = 0.114, < 0.001), and auditory stimuli of bedtime media use ( = 0.109, < 0.005) were all positively related to fatigue. Among students with normal levels of psychological distress, the relationship between psychological distress and fatigue was partially mediated by the visual stimuli of bedtime media use. In contrast, for students with severe psychological distress, the auditory stimuli of bedtime media use mediated the relationship between psychological distress and fatigue.
CONCLUSION
Based on the findings, psychological distress is indirectly associated with fatigue through the visual or auditory stimuli of bedtime media use. The visual and auditory stimuli exhibit different mediating effects among students with normal versus severe psychological distress. Interventions should focus on limiting bedtime media use to enhance health and reduce fatigue among college students experiencing psychological distress. Future studies may use longitudinal designs to establish causality or explore the reverse relationship between psychological distress and fatigue for a more robust finding.
背景
众多研究已将心理困扰与疲劳联系起来，但很少有研究探讨睡前使用媒体如何介导这种关系。本研究考察睡前使用视觉或听觉刺激是否介导大学生心理困扰与疲劳之间的关系。
方法
来自中国陕西省各大学的1831名中国大学生（927名男性和904名女性；平均年龄 = 20.36岁，标准差1.26）参与了本研究。使用电子问卷收集数据，该问卷评估心理困扰、睡前媒体使用情况和疲劳程度。采用自抽样法检验中介效应，随机样本为5000个，置信区间为95%。
结果
心理困扰（β = 0.256，p < 0.001）、睡前媒体使用的视觉刺激（β = 0.114，p < 0.001）和睡前媒体使用的听觉刺激（β = 0.109，p < 0.005）均与疲劳呈正相关。在心理困扰水平正常的学生中，心理困扰与疲劳之间的关系部分由睡前媒体使用的视觉刺激介导。相比之下，对于心理困扰严重的学生，睡前媒体使用的听觉刺激介导了心理困扰与疲劳之间的关系。
结论
基于研究结果，心理困扰通过睡前媒体使用的视觉或听觉刺激与疲劳间接相关。视觉和听觉刺激在心理困扰正常与严重的学生中表现出不同的中介效应。干预措施应侧重于限制睡前媒体使用，以增进健康并减轻有心理困扰的大学生的疲劳。未来的研究可采用纵向设计来确定因果关系，或探索心理困扰与疲劳之间的反向关系，以获得更有力的研究结果。
