观看短视频对青年人心理健康的影响——基于2020年中国家庭追踪调查数据的分析

The Impact of Watching Short Videos on Young People’s Mental Health:An Analysis Based on Data of the 2020 China Family Panel Studies

基于2020年中国家庭追踪调查(CFPS)数据,运用分位数回归、工具变量模型和中介效应模型,探讨了观看短视频对青年人心理健康的影响及其作用机理,并采用修正样本自选择偏差的双稳健IPWRA模型进行了稳健性检验。研究发现,观看短视频显著增加了青年人的抑郁风险。进一步分析表明,观看短视频对自身抑郁程度高的青年作用更明显,而对于本身抑郁程度低的青年则影响不大;观看短视频对低龄、女性、低学历、自评健康差的青年群体抑郁程度影响更大。中介效应检验发现,加剧晚睡程度、延长上网时间、减少锻炼频率均是观看短视频增加青年人抑郁风险的重要路径。

Based on the data of 2020 China Family Panel Studies(CFPS),this paper uses quantile regression,instrumental variable model and mediation effect model to explore the impact of watching short videos on young people’s mental health and its mechanism,and the robustness test is conducted by using the double-robust IPWRA model with modified sample self-selection bias.The study finds that watching short videos significantly increases depression risk among young people.The further analysis shows that watching short videos has a more significant effect on increasing depression risk among young people with high levels of depression,while it has little effect on young people with low levels of depression.Watching short videos has a greater impact on the degree of depression among young people who are younger,female,low education,and poor self-assessed health.The mediation effect test finds that watching short videos increases depression risk among young people by aggravating late sleep,prolonging the time spent on the Internet,and reducing the frequency of exercise.
