The Impact of Social Media Use on Adolescent Mental Health: A Systematic Analysis of Digital Engagement, Social Comparison, and Psychological Well-being

Abstract

This study examines the multifaceted relationship between social media use and mental health outcomes among adolescents, with particular emphasis on depression, anxiety, and self-esteem. Drawing upon recent empirical research and theoretical frameworks including Social Comparison Theory and the Dual-Systems Model of socio-emotional development, this analysis synthesizes findings from multiple international studies conducted between 2020 and 2025. The research reveals that problematic social media use has increased from 7% in 2018 to 11% in 2022 among adolescents globally, with higher rates observed among girls (13%) compared to boys (9%). Adolescents spending more than three hours daily on social media face double the risk of experiencing symptoms of depression and anxiety. The study identifies key mediating mechanisms including social comparison, approval anxiety, and fear of missing out (FOMO) that explain the relationship between digital engagement and psychological distress. Furthermore, the research explores protective factors and intervention strategies, including digital literacy programs and mental health literacy interventions that have demonstrated effectiveness in reducing negative outcomes. The findings have significant implications for parents, educators, healthcare providers, and policymakers in developing evidence-based approaches to promote healthy digital citizenship among young people. This comprehensive analysis contributes to the growing body of knowledge necessary for addressing the youth mental health crisis in the digital age.
