Digital Dilemma: Longitudinal Associations Between Social Media Engagement and Adolescent Mental Health Outcomes

Abstract

The present article focuses on the longitudinal findings on the relationships between the use of social media and their mental health outcomes in adolescents. The spread of social media sites has inherently changed how adolescents socialize fundamentally, offering both advantages in terms of bonding and dangers to mental health. The article synthesizes the existing evidence on the dynamics of these relationships over time, based on prospective cohort research, systematic reviews and meta-analyses published between 2016 and 2025. The results indicate the existence of complex, reciprocal relationships in which the use of social media is a predictor of further mental illness, and existing vulnerability conditions also determine trends in the use of digital media. These associations are mediated by different platforms, patterns of use and personal characteristics. Although the most recent findings of heavy social media use consistently demonstrate similarities in heightened depressive symptoms and psychological distress effects as time goes by, the extent of effect is also relatively small and differs significantly across literature. This review summarizes by offering advice to parents, educators, policymakers, and future research leads in order to overcome the digital dilemmas encountered by the modern youth.
