Clinical Trial 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.


Clinical Trial Description

PRIMARY OBJECTIVES: I. Augment an existing smartphone cessation app for smoking cessation with a video game to increase user engagement. II. Test the feasibility, engagement, and early efficacy of the 'gamified' app, compared to one without gamification. OUTLINE: Participants are recruited through the Smoke Free smartphone app and randomized to 1 of 2 arms. ARM I: Participants receive an educational intervention through the Smoke Free application (core app) with the embedded video game module. Participants complete questionnaires and may undergo saliva sample collection, if they report being smoke-free on follow-up. ARM II: Participants receive an educational intervention through the Smoke Free application without the video game module (core app only). Participants complete questionnaires and may undergo saliva sample collection, if they report being smoke-free on follow-up. ;
