This article provides a clinically grounded overview of the social media and mental health evidence base for an informed adult audience. It opens with four methodological caveats that apply across the literature: the correlation-causation problem, consistently small effect sizes (Orben & Przybylski, 2019), inconsistent measurement of both exposure and outcome, and publication bias toward positive findings.
Findings with reasonable empirical support are addressed: the passive-active use distinction (Verduyn et al., 2015), social comparison as a mechanism affecting body image and self-esteem particularly in adolescent girls (Fardouly & Vartanian, 2015), sleep disruption as a significant mediating variable (Scott et al., 2019), and cyberbullying as a clear and causally supported harm (Kowalski et al., 2014). Claims with weaker support are addressed directly: the dose-response assumption, the causal attribution of the mental health crisis to social media, and the characterisation of social media as uniformly harmful.
The article addresses platform design accountability — noting that harms associated with social media are the predictable consequences of engagement-optimised design choices rather than incidental outcomes — and a section on neurodivergent users covers both the genuine accessibility benefits and the specific risks of dopaminergic pull and social comparison in ADHD and autistic presentations.
