中文摘要：

基于社会学习理论和同伴规范影响理论，通过整群取样的方法从北京市两所高校中共选取3068名大一新生为被试，以问卷方式测查了大学生感知到的同伴网络过度使用行为和态度以及网络使用过程中的同伴压力和自身的网络成瘾程度；探讨了同伴的网络过度使用行为、态度对自身网络成瘾的影响及网络使用同伴压力在这一关系中的中介作用。结果表明：（1）大学生中的网络成瘾者所感知到的同伴网络过度使用行为、态度及网络使用时同伴压力均显著高于非网络成瘾者；（2）同伴网络过度使用行为、态度以及网络使用同伴压力均与网络成瘾的总分及五个维度得分呈显著正相关；（3）同伴网络过度使用行为可以正向显著地直接预测大学生网络戍瘾的程度，同时也会通过网络使用的同伴压力这一中介变量间接地预测大学生的网络成瘾程度；但同伴的网络过度使用态度不能直接预测自身的网络成瘾程度，而是通过同伴压力间接地影响自身的网络成瘾程度。结论：网络使用过程中的同伴压力在同伴网络过度使用行为影响自身网络成瘾程度关系中起部分中介作用，而在同伴网络过度使用态度影响自身网络成瘾程度关系中起完全中介作用。

英文摘要：

Based on Bandura theory of social learning and related theories about effect of peer norms, a cross- sectional study was conducted in Beijing to explore the relationship between Perceived Peers＇ Internet Overuse Behavior, attitude on Internet Overuse, pressures of Internet using and College students＇ Internet addiction. 3049 college students from two universities in Beijing city were invited to fulfill the questionnaire about the peers＇ Internet overuse behaviors, attitude on Internet overuse, pressures when they using Internet and Internet addiction level. Structural equation model were used to explore the affect mechanism of peers＇ pressures on the relationship between peers＇ Internet overuse behavior and attitude and Internet addiction. The results showed that： （1） Compared to Internet non-addicts, Internet addicts among college students perceived more Internet overuse behaviors and higher pressure from peers, and more positive attitudes about Internet overuse. （2） College students perceived peers＇ Internet overuse behaviors and attitude on Internet overuse; pressures of Internet using were positively correlated to Internet addiction. （3） Peers＇ lnternet overuse behaviors not only have a direct effect on college students＇ Internet addiction, but also have an indirect effect on Internet addiction through peers＇ pressure; meanwhile, Peers＇ attitude on Internet overuse can＇ t predict college students＇ Internet addiction directly, but have an indirect effect on Internet addiction through peers＇ pressure. Conclusion： Peers＇ pressure play a partial mediation effect on the relationship between Peers＇ Internet overuse behaviors and college students＇ Internet addiction level. Meanwhile, peers＇ pressures play a full mediation effect on the relationship between Peers＇ attitude on Internet overuse and college students＇ Internet addiction level.
