Gaming found to help soldiers cope better than other activities

A 2009 study by the Mental Health Advisory Team of the United States Army examined how activities like listening to music, working out, or using Facebook affected 1,000 soldiers in Afghanistan. At the end of the study, the activity that seemed to help the soldiers cope the best was playing videogames.

Soldiers that played games had the lowest rates of PTSD, domestic violence, depression, and suicide attempts. It's worth noting that these effects mostly went away in those that played over 28 hours a week. Those that played 40 hours per week were far more likely to be in some state of psychological distress. In moderation, however, games seemed to have positive effects.
