Abstract:
Objective: To investigate the role of perceived stress and loneliness on
the association between excessive smart phone use and poor sleep quality among
Chinese college students. Methods: A sample of 573 Guangzhou Medical University
students completed measures of excessive smart phone use, perceived stress, loneliness
and sleep quality. Results: Excessive smart phone use was positively related to both
perceived stress and loneliness, which in turn significantly related to decreased sleep
quality. Thus perceived stress and loneliness indeed mediate the relationship between
excessive smart phone use and poor sleep quality. Specifically, the two mediating
factors play both concurrent and sequential roles in the mediation chain. Conclusion:
These findings advance our understanding of how excessive smart phone use
associated with college students’ poor sleep quality and enlighten future intervention
programs aimed to improve the sleep quality among those young adults.
目的:调查大学生感知压力和孤独感在手机成瘾倾向与睡眠质量之间的中介效应。方法:采用大学生压力量表(SSCS)、UCLA 孤独感量表、手机成瘾倾向指数量表(MPAI)和匹兹堡睡眠质量指数(PSQI)对广州地区某医科院校 573 名在校大学生进行问卷调查。结果:智能手机成瘾倾向总分与感知压力和孤独感呈显著正相关,而孤独感又与睡眠质量总分存在显著负相关。Bootstrap 检验结果表明,感知压力和孤独感在手机成瘾倾向和睡眠质量之间起部分中介作用。同时,感知压力和孤独感构成链式中介效应。结论:研究促进我们对手机成瘾倾向与大学生低睡眠质量关联机制的理解,并能够为改善大学生睡眠质量的干预措施提供一定启示。
