Playing video games for less than one hour per day has been found to be linked to better-adjusted children.

A new study suggests that young people who engage in a little video game-playing were better adjusted compared to those who either never play video games, or play for over three hours daily. No effects – whether positive or negative – were found on young people who play a “moderate” amount of video games on a daily basis.

It’s estimated that 97 percent of teens in the U.S. play video games, with sales of these games growing every day.

The study’s author Dr. Andrew Przybylski from the Oxford Internet Institute and colleagues found that any influence of video games on children is very small in comparison to more lingering factors, such as whether the kids have healthy school relationships, or come from a functional family.

The study included almost 5,000 young people between the ages of 10 and 15 years from households in the UK. The participants were asked about how much time they spend playing video games on a daily basis, and were also asked about the status of their family life, peer relationships, and level of empathy.

The researchers found that those who spend more than three hours a day playing video games were not well-adjusted.

“These results support recent laboratory-based experiments that have identified the downsides to playing electronic games. However, high levels of video game-playing appear to be only weakly linked to children’s behavioural problems in the real world. Likewise, the small, positive effects we observed for low levels of play on electronic games do not support the idea that video games on their own can help children develop in an increasingly digital world,” said Przybylski in a statement.

The findings of the study are published in the journal Pediatrics.
