Impact of Ecological Momentary Assessment Participation on Short-term Smoking Cessation: Results from the quitSTART EMA Incentivization Trial (Preprint)

This study attempted to isolate and examine the effect of incentivizing EMA engagement on smoking cessation success for adults using a smartphone app to quit. While participants randomized to incentivization of EMA showed higher engagement with this feature, our findings suggest that there was no additional short-term cessation benefit from this engagement. Crude analyses found a potential benefit for allowing autonomy over the use of app features, despite the ability of EMA completion to provide real-time, tailored cessation support.
