Excessive Internet use in adolescents and young people is related to intrapersonal and interpersonal difficulties. The aim of this research was to study the relationship between problematic Internet use, psychological well-being, and responses of social anxiety and obsessive-compulsive. Participants were 132 male and 178 female high school and college students aged between 16 and 23 years. The results indicate that age influences most of the factors of compulsive Internet use. Gender affects the levels of problematic Internet use, with males scoring higher in Compulsive Internet Use and Negative Outcomes. A significant and direct correlation was found between problematic Internet use and responses of social anxiety and obsessive-compulsive. The main predictors of problematic Internet use were: Environmental mastery, Social anxiety and Obsessive-compulsive symptoms. It can be concluded, tentatively, that while young people with social anxiety could find the Internet use a means of pleasant interaction, young people with obsessive-compulsive symptoms could become excessive Internet users as a means to eliminate compulsive anxiety.
