   The association between adolescent well-being and digital technology use

   Nature Human Behaviour (Orben & Przybylski)Published Jan 8, 2019Checked Sep 30, 2026

   “Using specification curve analysis on three large datasets covering 355,358 adolescents in the US and UK, the association between digital technology use and adolescent wellbeing was negative but small, explaining at most 0.4% of the variation in wellbeing.”

   Social Media and Mental Health

   American Economic Review (Braghieri et al.)Published Oct 26, 2022Checked Sep 30, 2026

   “We provide quasi-experimental estimates of the impact of social media on mental health by leveraging a unique natural experiment: the staggered introduction of Facebook across US colleges. Our analysis couples data on student mental health around the years of Facebook’s expansion with a generalized difference-in-differences empirical strategy. We find that the rollout of Facebook at a college had a negative impact on student mental health. It also increased the likelihood with which students reported experiencing impairments to academic performance due to poor mental health. Additional evidence on mechanisms suggests the results are due to Facebook fostering unfavorable social comparisons. (JEL D91, I12, I23, L82)”

   The Welfare Effects of Social Media

   American Economic Review (Allcott et al.)Published Feb 28, 2020Checked Sep 30, 2026

   “The rise of social media has provoked both optimism about potential societal benefits and concern about harms such as addiction, depression, and political polarization. In a randomized experiment, we find that deactivating Facebook for the four weeks before the 2018 US midterm election (i) reduced online activity, while increasing offline activities such as watching TV alone and socializing with family and friends; (ii) reduced both factual news knowledge and political polarization; (iii) increased subjective well-being; and post-experiment Facebook use. Deactivation reduced post-experiment valuations of Facebook, suggesting that traditional metrics may overstate consumer surplus. (JEL D12, D72, D90, I31, L82, L86, Z13)”

   Social media and youth mental health: the U.S. Surgeon General's advisory

   US Department of Health and Human ServicesPublished May 23, 2023Checked Sep 30, 2026

   “Up to 95% of youth aged 13–17 report using a social media platform. Adolescents who spend more than three hours a day on social media face double the risk of poor mental health outcomes, including symptoms of depression and anxiety. There is not yet enough evidence to conclude that social media is sufficiently safe for children and adolescents.”

   Parasocial Engagement With Social Media Influencers and Mental Health Outcomes: Systematic Review and Meta-Analysis.

   JMIR mental health (Li et al.)Published Aug 20, 2026Checked Oct 4, 2026

   “Well-being showed the largest effects (r=0.42), followed by social media addiction (r=0.33). PSI demonstrated stronger associations than PSR (r=0.56 vs 0.22). Effects were largest among adolescents (r=0.44) and in Eastern samples (r=0.61 vs 0.29). No evidence of publication bias was detected (Egger P=.94; fail-safe N=18,643).ConclusionsParasocial engagement functions as a psychological double-edged sword, reliably linked to both enhanced well-being and problematic engagement. Positive mental health outcomes, particularly those involving well-being, were generally stronger and more consistent than negative ones. These findings suggest that parasocial engagement should not be understood as uniformly beneficial or harmful; rather, its psychological meaning depends on the outcome domain, parasocial construct type, developmental stage, and cultural context. Future longitudinal, mechanism-based research with diverse samples is needed to clarify when parasocial engagement is most beneficial or harmful.”

   Momentary Mood and Affiliation Following Social Interactions in the Digital Age: Longitudinal Study Investigating Associations With Anxiety and Depression.

   JMIR mental health (Bilston et al.)Published Aug 10, 2026Checked Oct 4, 2026

   “Anxiety, but not depression, was associated with feeling less happy, but not less included, after social interactions. Affective and affiliative responses to in-person, but not online, social interactions were negatively associated with depression across the 1-month study period. Finally, social sensitivity moderated the relationship between affective and affiliative responses to social media interactions and depression at baseline. Overall effect sizes were small.ConclusionsThese findings emphasize the need to investigate individual factors influencing for whom online social interaction is harmful or beneficial. To do so, this study provides a novel, ecologically valid tool for understanding young people's momentary responses to online and offline social interactions, as well as initial evidence for stronger associations between in-person than online social interaction responses and mental health for older adolescents and emerging adults. It also introduces evidence of social sensitivity as a potential, developmentally relevant vulnerability to the effects of online social interaction. Further research is needed in younger adolescent populations over longer timeframes.”

   The impact of social media on athletes' mental health: a systematic review.

   Frontiers in sports and active living (Siaj et al.)Published Aug 6, 2026Checked Oct 4, 2026

   “Across the included studies, social media use was frequently associated with negative mental health outcomes, including anxiety, depressive symptoms, emotional distress, body image concerns, and burnout. Passive engagement, appearance-based comparison, and problematic use patterns were more consistently linked to poorer psychological outcomes, whereas active engagement and context-dependent use showed mixed or potentially protective associations. However, given the predominance of cross-sectional designs, heterogeneity in measurement, and the still limited number of studies, these findings should be interpreted cautiously. Overall, current evidence suggests that social media use may relate to athletes' mental health in complex and context-dependent ways. The strength and direction of associations appear to vary according to usage patterns, developmental stage, and competitive level. Further longitudinal, platform-specific, and elite-focused research is required to clarify mechanisms, temporal relationships, and population-specific effects.”
