01
A 2023 Oxford study of 162,000-plus in-game mood reports from over 8,600 players found that playing video games improved mood more than watching television, reading or shopping.See it on page 5

Summary

The Positive Research Compendium, a curated reference of third-party, peer-reviewed research on the effects of video games on health, cognition and well-being, is intended for policy, legal and advocacy teams. It organizes studies across five subject areas: well-being and mental health, physical effects, learning and cognitive development, gaming disorder, and violence. Research is drawn from 2008 onward, with the most recent work (2025-2026) placed first in each section. The compendium also lists the universities and research bodies most active in this field, selected regardless of their position on the subject.

On well-being, the document states that multiple large-scale studies consistently find a small but meaningful positive relationship between playing video games and mental well-being, and that hours played is a poor predictor of outcomes compared with why, how and in what context people play. On gaming disorder, it reports that depression, anxiety and ADHD are more reliable predictors of problematic gaming than its consequences, and that a 2026 review found roughly 70% of 500 cited survey studies failed to exclude gambling data. On violence, it states that multiple independent lines of evidence find no meaningful causal link between violent gameplay and real-world aggression.
