Against the backdrop of a deepening mental health crisis among American teenagers, a newly released survey of teens and their parents by the Pew Research Center reveals that teens are increasingly concerned about social media’s effect on people their age.

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

Research shows that, over the past two decades, rates of mental illness have been increasing in adolescents in many countries. While some scientists point to soaring use of smartphones and social media as a key driver for this trend, others say the evidence does not show a large effect of these technologies on teenagers’ psychological health.
