The future of mobility is going to be decided right here in the state is a planet dot com to find out why that's p. L. a. n. e. t. m. dot com. It is quality not quantity that counts was as up writing about screen time and adolescent mental health from american public media. This is marketplace tech demystifying the digital economy. I'm jed kim in for molly. Would it feels like we're constantly bombarded with new stories race about how screens and technology are destroying our kids. Mental health turns out though when it comes to adolescence those negative impacts of screen time may be overblown own. Mike lynn johnson is an assistant professor of psychology at the university of north carolina at greensboro. She led a team that did a longitudinal study following up with a group of students over a couple of years asking how they're using tack and how they're feeling then they collected more than thirteen thousand observations on hundreds of those kids ads and the results were pretty different from a lot of the familiar headlines when it comes to kids and screens i would say i was a bit surprised but our findings are actually quite consistent. Stint with an emerging body of literature was suggests that these correlations that have been observed between technology mental health are actually quite small and those small effect sizes. Perhaps we're gleaned from the earlier studies when not all teams were using technology to the same degree in today's day and age where the vast majority of of teens are pretty digitally connected. It looks like it's more normal for teens to have a lot of engagement online and that perhaps it's not linked with negative mental health outcomes and there there are also some definite positives associated with screens and time spent online yeah so the broader literature has recently suggested that teens who are most needing support actually go online to get it in the form of social support or maybe searching for information about their mental health difficulties and actually in our study one one of the few significant findings that did emerge was that those teenagers who were the heaviest tax messengers who spent the most time messaging actually eight reported less depression than those teams who were less frequent tax messengers so that might mean that perhaps teens are using in these online tools so like text messaging and that it's serving as a strength a source of social support for instance you as parents we do have some tools rules to establish you know parental controls over what our kids are doing and seeing is that a good answer is being oversold. This study would suggest us that parental controls are based just on time so like the number of minutes that your kid can watch netflix and then it shuts off automatically. I don't know that that's going to be you. Are magic bullet for helping kids use technology in a way that is pro social and aids in their development if the parental controls were more nuanced johnston got out. The quality of what kids are doing online. Maybe but i don't know how effective those are at this point. I think my advice for right now where the technology's -nology stands is that it's important for parents to talk to their kids and that that doing the legwork is probably a better way of making sure that your kids stay safe and using technology in a way that's helpful not harmful to them rather than relying on a new technology that we're not quite sure yet how it works. Mike lynn johnson. Listen is a clinical psychologist and research psychology at the university of north carolina at greensboro. She suggests spending time with your kids watching the youtube videos they like or you even playing fortnight with them.

There are three get at least eight hours of sleep exercise for at least an hour and spend less than two hours looking at screens. What percentage of teens achieve all three less than ten percent. The exercise wants the real killer how why do american teams fair. I don't know i was too afraid to look especially considering. I myself fail on each of the goals. The independent is a story. That's a fun read trade. Even if i am a little suspicious of its scientific merit a survey polled a thousand nursery workers most of them believe screens are hurting kids creativity.
