This document summarizes a webinar presented by Tom Baranowski on using games for health. It discusses how games can engage players to promote behavior change for chronic illness management and obesity prevention since traditional approaches often have low adherence. Serious games incorporate story, feedback, and rewards to motivate players. Research shows games can produce behavior changes, and several games developed by Baranowski for diet and activity are presented. Future research needs to better understand how to maximize fun in games to improve health behavior change outcomes.
