The impact of social media on young people’s mental health and well-being is a growing topic of concern among parents, educators, health care professionals and regulators. And now, nearly half of US teens say social media has a mostly negative effect on people their age — and almost the same proportion say they’re cutting back on social media use.

Parents are more worried than teens about teen mental health. Both groups – especially parents – partly blame social media. But teens also see benefits.

A recent Pew Research Center study also found 48% of teens agree social media has a largely negative impact on teens.
