Screen-addicted teens are unhappy

A new study explored the link between adolescent life satisfaction and screen time. Researchers found that teens who spent more time in front of screen devices -- playing computer games, using social media, texting and video chatting -- were less happy than those who invested more time in non-screen activities like sports, reading newspapers and magazines, and face-to-face social interaction.

Total screen avoidance doesn't lead to happiness either. The greater unhappiness among those with no screen exposure could be due to several factors, Twenge, the leading researcher said. “It could be that they are left out of the social scene of high school, that it’s very difficult to carry on friendships in high school these days without texting at all or being on social media.” It is also possible that those kids are outliers, Twenge said — teens with special needs or in special education, or those whose screens have been taken away from them by parents.

The key to digital media use and happiness is limited use. The happiest teens used digital media a little less than an hour per day. But after a daily hour of screen time, unhappiness rises steadily along with increasing screen time, the researchers report in the journal Emotion.

"Make effort to spend no more than two hours a day on digital media, and try to increase the amount of time you spend seeing friends face-to-face and exercising -- two activities reliably linked to greater happiness." Twenge said.

"By far the largest change in teens' lives between 2012 and 2016 was the increase in the amount of time they spent on digital media, and the following decline in in-person social activities and sleep," the leading researcher said. "The arrival of the smartphone is the most reasonable explanation for the sudden decrease in teens' psychological well-being."
