About this trial
The mental health of adolescents in the United States has seen a steep decline, roughly coinciding with the increasing popularity of social media and smartphones. But does social media have a causal impact on the mental health of adolescents or are concerns about the effect of social media on kids a form of public hysteria? In this study, the investigators will conduct the first field experiment in 10-14-year-olds to examine whether, how, and for whom social media harms mental health.
