Nonlinear Relationships Between Time Spent on Different Types of Internet Services and Mental Health
摘要
Abstract
Objective To investigate the relationships between time spent on different types of Internet services and mental health,including linear and nonlinear relationship. Methods In December 2013,a five -item version of the mental health inventory(MHI-5)and a self-made questionnaire about time spent on different types of Internet services(including six types of Internet services:social network sites,instant messaging tools,online videos,online games,online shopping,other webpages)were administrated on 152 students. Pearson correlation analysis and hierarchical polynomial regression analysis were conducted to investigate the relationships between time spent on different types of Internet services and mental health. Results There were 139 valid responses(valid return rate was 91. 5%). There was no significant linear relationship between time spent on six types of Internet services and mental health(r= -0. 14~0. 03,P﹥0. 05). The square of time spent on social network sites(SNS)showed statistic significance in its regression coefficient to mental health(β= -0. 25,P﹤0. 05). Besides,time spent on SNS and mental health had a reversed-U curve relationship. Conclusion Time spent on SNS and mental health have a reversed-U curve relationship,which means moderate SNS users have better mental health compared to non SNS users and excessive SNS users.关键词
