摘　　要：目的考察不同类型网络应用使用时间与心理健康的关系,包括线性与非线性关系。方法 2013年12月,采用自编网络应用使用时间问卷（包括社交网站、聊天工具、网络视频、网络游戏、购物网站、其他网页6种类型的网络应用）与心理健康问卷（five-item version of the mental health inventory,MHI-5）对北京某大学的学生152例进行问卷调查。二者关系研究采用皮尔逊相关分析以及分层多项式回归分析。结果回收有效问卷139份,有效率为91.5%。学生心理健康得分为（4.46±0.74）分,所有类型的网络应用使用时间与心理健康的线性相关关系均无统计学意义（r值为-0.14~0.03,P〉0.05）。社交网站使用时间的平方对心理健康的回归系数有统计学意义（β=-0.25,P〈0.05）,且社交网站使用时间与心理健康的曲线关系为倒U型。结论社交网站使用时间与心理健康呈倒U型关系,即适度使用社交网站的个体其心理健康水平高于使用时间过长或者过短的个体。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.
