Understanding the Social Media Rollercoaster: How Resilience and Vulnerability Shape Teen Mental Health

Abstract : Background: Social media is a central part of adolescent life, yet its impact on mental health is highly variable. Objective: To present a synthesized, three-layer framework explaining how individual traits, social environments, and digital behaviors interact to buffer or exacerbate the relationship between social media use and adolescent mental health.Methods: We analyzed key findings from recent studies (2020-2025) identified via a systematic PubMed search, focusing on moderators such as personality, coping styles, social support, and digital literacy. Results: An adolescent’s experience is shaped by three key layers: The Inner Self (personal traits and coping), the Social Environment (interpersonal support), and Digital Engagement (online skills and use patterns). Low self-esteem, maladaptive coping, lack of social support, low digital literacy, and younger age are key factors that increase vulnerability to negative outcomes from social media use. Conclusion: The impact of social media is not uniform but conditional. Effective support requires targeted interventions that build self-esteem and coping skills, foster supportive communication, and teach critical digital literacy. This multi-layered approach can help teens navigate the digital world with greater resilience.
