The study aimed to investigate the associations between different types of screen time (ST) and anxiety and depressive symptoms in college students during the Coronavirus disease 2019 (COVID-19) outbreak in Shanghai, China; the potential mediation role of sleep quality was also examined. A total of 1,550 college students completed an online survey in May 2022. ST, Self-rating Anxiety Scale (SAS) score, Self-rating Depression Scale (SDS) score, Pittsburgh Sleep Quality Index (PSQI) score, and physical activity were self-reported. Multiple linear regression and mediation analysis were conducted. The results showed that more time spent in TV/movie viewing (>2 h/day) and recreational reading (>1 h/day) was associated with higher levels of anxiety, while more time spent in online social media (>2 h/day) was associated with a higher level of depressive symptoms. In contrast, time spent in online social media (1-2 h/day) was associated with a lower level of anxiety. Meanwhile, recreational reading (2-3 h/day) had a significant indirect effect on anxiety and depressive symptoms through sleep quality. During the COVID-19 outbreak, the associations of ST with anxiety and depressive symptoms varied by the type of screen viewing in college students. The associations of slightly excessive time spent on recreational reading with higher levels of anxiety and depressive symptoms were partially mediated by sleep quality.
本研究旨在调查2019年冠状病毒病（COVID-19）疫情期间，中国上海大学生不同类型的屏幕使用时间（ST）与焦虑和抑郁症状之间的关联；同时还考察了睡眠质量的潜在中介作用。2022年5月，共有1550名大学生完成了一项在线调查。ST、自评焦虑量表（SAS）得分、自评抑郁量表（SDS）得分、匹兹堡睡眠质量指数（PSQI）得分以及体育活动情况均为自我报告。进行了多元线性回归和中介分析。结果显示，花在看电视/电影上的时间超过2小时/天以及花在休闲阅读上的时间超过1小时/天与更高水平的焦虑相关，而花在在线社交媒体上的时间超过2小时/天与更高水平的抑郁症状相关。相反，花在在线社交媒体上的时间为1至2小时/天与较低水平的焦虑相关。同时，休闲阅读时间为2至3小时/天通过睡眠质量对焦虑和抑郁症状有显著的间接影响。在COVID-19疫情期间，大学生中ST与焦虑和抑郁症状的关联因屏幕观看类型而异。花在休闲阅读上的略超量时间与更高水平的焦虑和抑郁症状之间的关联部分由睡眠质量介导。
