Despite these limitations, this comprehensive systematic review demonstrates that video games may have potential for improving health in a wide variety of areas, for a variety of sociodemographic groups. This is a valuable finding, particularly given the growing popularity and ubiquity of video games worldwide. To most effectively assess the potential benefits of video games for health, it will be important for further research to utilize (1) RCT methodology when appropriate; (2) longer follow-up duration; (3) improved measures of quality, such as randomization and blinding; and (4) standardized measurement tools and careful attention to the quality of outcome measures.
