Playing violent video games such as Grand Theft Auto and Call of Duty does not cause anti-social behaviour, according to a study of American teenagers.
Research involving 377 children with an average age of 13, some of whom had attention deficit hyperactivity disorder (ADHD) or depression, challenged the perception that gory games can trigger violent behaviour.
“We found no evidence that violent video games increase bullying or delinquent behaviour among vulnerable youth with clinically elevated mental health symptoms,” said Professor Ferguson of Stetson University in Florida.
Instead researchers found that violent games could sometimes be therapeutic and make children with ADHD less aggressive, although study leader Christopher Ferguson stressed the results should be treated "cautiously".
Children in the study were asked about their favourite video games, their experiences of bullying, violence and stress, and how they would react in a confrontation.
Earlier this week, an eight-year-old boy from Louisiana reportedly murdered an elderly woman after playing Grand Theft Auto IV.

A one-off edition of the new racing game GRID 2 will come with a "free" road-legal racing car customised to look like one of the virtual cars in the game.

Neill Briggs, a founding director of BAC-Mono, said the company has already been approached by "quite a lot of people who have expressed more than an interest".
GRID2 goes on sale in the UK today.
