People are quick to point the finger or dismiss the effect of violent video games as a factor in criminal behavior. New evidence from Iowa State researchers demonstrates a link between video games and youth violence and delinquency.

Matt DeLisi, a professor of sociology, said the research shows a strong connection even when controlling for a history of violence and psychopathic traits among juvenile offenders.

"When critics say, 'Well, it's probably not video games, it's probably how antisocial they are,' we can address that directly because we controlled for a lot of things that we know matter," DeLisi said. "Even if you account for the child's sex, age, race, the age they were first referred to juvenile court -- which is a very powerful effect -- and a bunch of other media effects, like screen time and exposure. Even with all of that, the video game measure still mattered."

"Can we say from this study that Adam Lanza, or any of the others, went off and killed people because of media violence? You can't take the stand of the NRA that it's strictly video games and not guns," Anderson said. "You also can't take the stand of the entertainment industry that it has nothing to do with media violence that it's all about guns and not about media violence. They're both wrong and they're both right, both are causal risk factors."

Just because a child plays a violent video game does not mean he or she is going to act violently. Researchers say if there is a take away for parents, it is an awareness of what their children are playing and how that may influence their behavior.

"I think parents need to be truthful and honest about who their children are in terms of their psychiatric functioning," DeLisi said. "If you have a kid who is antisocial, who is a little bit vulnerable to influence, giving them something that allows them to escape into themselves for a long period of time isn't a healthy thing."
