Gaming‑Based Community Intervention for Loneliness in Adult Gamers: Longitudinal Observational Study

A professionally moderated, gaming‑based community intervention was feasible to deliver, engaged a diverse sample of adult gamers, and was associated with medium‑sized reductions in depressive and anxiety symptoms and small improvements in well‑being and psychological flexibility over 60 days. A subgroup moved from moderate‑to‑severe symptoms to subthreshold depressive symptoms. These findings support further controlled evaluation of health‑supporting gaming communities as a scalable support and potential preventive context for adult gamers experiencing distress.
