Past research on adolescents＇ addiction to the Interact has revealed that most addicts are low in self-concept and show withdrawal behavior in social interactions. And among college students who are addicts, there is a reported connection between online experience and addictive behavior.

With regard to school type, there was also a significant main effect （β=.051, p=.001）, indicating that students from key schools were more vulnerable to Intemet addiction than those from non-key schools. Moreover, there was a significant three-way interaction among self-concept, negative online experience and school ty
