Another Study Eyes Games & Aggressive Behavior Correlation

A new study undertaken by a group of Massachusetts General Hospital researchers attempts to further explore whether a link exists between playing violent videogames and aggressive behavior in adolescents.

“M-Rated Video Games and Aggressive or Problem Behavior Among Young Adolescents” surveyed 1,254 7th and 8th grade students in Pennsylvania and South Carolina in late 2004. Youths were asked which five games they had “played a lot” in the past six months and were asked to detail any “delinquent,” bullying or physically aggressive behaviors.

Among those who were current game players, 48.8% (67.9% boys and 29.2% girls) had at least one M-rated game on their most-played list. Cross tallying and crunching variables led the researchers to conclude:

M-rated games remained a strongly significant predictor of engaging in bullying and physical aggression However, we found no significant relationship between playing M-rated games and being a victim of bullies, or engaging in delinquent behaviors.

Boys were then split off from girls and their responses analyzed separately. With boys “M-rated game exposure ceased to be a significant predictor of bullying, and aggressive personality,” though “M-rated game play was still a significant, though weaker, predictor of fighting.”

With girls, “frequent M-rated game use became an even stronger predictor of bullying and fighting.”

The group concluded:

Overall, our hypothesis that heavy play of Mature-rated, violent games would predict a greater risk for common problem behaviors, even when controlling for potential confounders suggested by previous research, was partially supported.

The researchers pointed out a few limitations of their study, which included the fact that “Involvement in problem behaviors is common among adolescents.” Also, responses from the children indicating their top five games of the past six months were not independently verified.

Interestingly, in touching on legislation that seeks to ban children’s access to “violent” videogames, and asking “who would determine whether a game fits these critieria,” the study states, “Because of these complexities, it is unlikely that a narrow category of games could be clearly identified and supported by research as broadly harmful to young people.”

GP: We have an inquiry in with one of the researchers to make sure that's it's OK to post the whole study (PDF) on the website.

Update: Just a note that the research team included Dr. Cheryl Olson, co-author of Grand Theft Childhood.
