Instagrowth: A Longitudinal Growth Mixture Model of Social Media Time Use Across Adolescence


social media, adolescents, impact of social media, adolescent social media use


This study examined differential patterns of time spent using social media in a sample of 457 adolescents over a 6‐year period. The majority of adolescents (83%), termed moderate users, reported steady social media use over time. A second group (increasers: 12%) reported low social media use that increased gradually and ended high at the end of the study. A third group, called peak users (6%), reported low social media that increased quickly after a few years and then returned to baseline levels. Low self‐regulation predicted being an increaser or peak user. Being a moderate user tended to be related to lower levels of depression, aggression, delinquency, social media problems, and cyberbullying across time, as compared with the other groups.
