The correction for baseline distress increases the likelihood that spending more time on social media is a cause rather than a result of greater distress, which seems driven more by internalizing behavior than by externalizing behavior, although a common factor could predispose youth to both social media use and internalizing symptoms. Potential mechanisms could involve disrupted sleep, adverse online experiences, feelings of inadequacy compared with online contacts, and lack of practice with real-life relationships. Limiting time on social media could be helpful to depression-prone adolescents, if it does not deprive them of positive online experiences.
