Study: Too Much Screen Time Makes Kids Mental

If your child spends most of his days staring at some kind of screen, he may very well grow up to be a psycho, according to one new U.K. study, at least. The study, conducted by researchers from the University of Bristol, involved a group of children aged 10 to 11, each of whom were given a standard test to measure behavioral problems, and asked to report the amount of time they spend in front of either a computer or TV screen. As Ars Technica points out, the authors did acknowledge that there's always a certain level of statistical uncertainty when dealing with self-reported numbers, but they did equip the kids with accelerometers to get more accurate measures of the time they spent sedentary.

Once they had reviewed the collected results, researchers found that the kids who had spent more than two hours a day in front of a TV or computer screen were more likely to have behavioral problems. Kids who had spent more time not moving, meanwhile, actually exhibited better test results. Surprisingly enough, though, the results showed a significant, yet weak inverse relationship between time spent in front of a screen and idle time, but virtually no correlation (positive or negative) between a child's screen time and his or her exercise activity. The kids' test scores didn't vary, moreover, across the two different types of screens (computer or TV).

Of course, it's difficult to isolate the effect that screen time has on a child's behavior. Pre-existing problems at home or at school, for example, may force some kids to seek refuge in video games or computer programs, so it may be impossible to establish a robust causal relationship between the two. Either way, paranoid parents may want to limit their kids' screen time, just in case it really is poisoning their psyches.
