Summary
This study evaluates the effects of a video game embedded in a commercially available mobile application (app) for smoking cessation. Smokers are increasingly turning to mobile health apps for assistance with quitting smoking, and there is a critical need for strategies to engage app users to increase retention and efficacy. Video games are designed to increase users' motivation and engagement, which in turn may increase their exposure and adherence to a smoking cessation program. The hypothesis is that the game increases engagement, retention, and smoking abstinence rates compared with a core version of the app without the game. A two-arm individually randomized pilot trial of 500 adult smokers will test this hypothesis, comparing outcomes for participants randomized to receive the core app plus embedded game with participants randomized to receive the core app only. Primary outcomes relate to user engagement with the app. Secondary outcomes relate to user engagement, efficacy (smoking abstinence), and user satisfaction.
