智能手机成瘾在医学生焦虑和睡眠质量间的中介效应

Mediating effect of smartphone addiction on anxiety and sleep quality of medical students

目的 探讨医学生焦虑情绪和睡眠质量的关系,及智能手机成瘾的中介效应。方法 采用广泛性焦虑量表(general anxiety disorders-7 scale,GAD-7)、阿森斯睡眠量表(Athens sleep scale,AIS)和智能手机成瘾量表(smartphone addiction scale,SAS-SV),于2020年11—12月对安徽省某医学院校2 850名医学生进行调查。结果 医学生焦虑1 337人(46.9%),睡眠障碍629人(22.1%)以及智能手机成瘾1 350人(47.4%);医学生焦虑与年龄、年级、是否喜欢所学专业等因素有关(均P<0.05);Pearson相关分析显示,医学生焦虑与睡眠障碍、智能手机成瘾均呈显著正相关(r=0.588、0.434,均P<0.01),并且焦虑对医学生睡眠质量和智能手机成瘾有正向预测作用(β=0.532、0.434,均P<0.01),智能手机成瘾在焦虑和睡眠质量间起部分中介效应。结论 焦虑会直接对睡眠质量产生影响,也会间接通过智能手机成瘾的中介效应对睡眠质量产生影响。

Objective To explore the relationship between anxiety and sleep quality of medical students,and the mediating effect of smartphone addiction.Methods The the general anxiety disorders-7 scale(GAD-7),the Athens sleep scale(AIS) and the smartphone addiction scale(AS-SV) were used to investigate 2 850 students in a medical college in Anhui Province from November to December 2020.Results There were 1 337(46.9%) medical students with anxiety,629(22.1%) with sleep disorders and 1 350(47.4%) with smartphone addiction.The medical students’ anxiety was related to factors such as age,grade,and whether they like their major(P<0.05).Pearson correlation analysis showed that the medical students’ anxiety was significantly positively correlated with sleep disorders and smartphone addiction(r=0.588,0.434,both P<0.01),anxiety had a positive predictive effect on medical students’ sleep quality and smartphone addiction(β=0.532,0.434,both P<0.01),and smartphone addiction played a part of the mediating effect between anxiety and sleep quality.Conclusion Anxiety not only directly affect sleep quality,but also indirectly affect sleep quality through the mediating effect of smartphone addiction.
