For today’s youth, taking a selfie is like second nature. But their connections with social media may be skewing their view of their world.

Being a teenager is tough already — is too much screen time making it tougher?

A new study shows frequent social media use and television viewing is linked to depression in teens.

“If screen time changes and you see depression changing, you can begin to start considering whether it is a causal relationship,” the study’s lead author, Dr. Patricia Conrod, said in an interview with ABC News.

Researchers followed almost 4,000 Canadians aged 12 to 16 over four years. Every year, students completed a survey about the amount of time they’d spent in front of digital screens and the specific type of activity they had engaged in — social media, television, video-gaming or computer use. Surveys also asked them to self-score their depressive symptoms.

Over the course of four years, as little as a one-hour annual increase in social media or television viewing was associated with more severe depressive symptoms and lower self-esteem.

The study didn’t suggest all screens were a problem. Increasing video gaming and computer use was not associated with increases in depressive symptoms, most likely because these platforms are more interactive and are less likely to make teens directly compare themselves with others.

“Television and social media, more than any other types of media, expose young people to content and images that accentuates the unrealistically positive and idealized presentation of other young people,” Conrod said. “Kids form unrealistic expectations of what is normal, which makes them feel like they are not measuring up.”

For those in the study who were prone to higher levels of depression, as social media use went up, so did their symptoms. The relationship suggested a spiral, as teens who were more depressed were more likely to view content that validated their state of mind.
