What we've known from other studies is that video gaming addiction looks similar to other addictions. But what wasn't clear was what comes before what. Gaming might be a secondary problem. It might be that kids who are socially awkward, who aren't doing well in school, get depressed and then lose themselves into games. We haven't really known if gaming is important by itself, or what puts kids at risk for becoming addicted," said Douglas A. Gentile, an associate professor of psychology at Iowa State University in Ames.
