Combining EMA self-reports with GPS based mobility data to understand health behaviours

Ecological Momentary Assessment (EMA) is a method to collect real time data in the natural environment, and typically participants complete multiple short questionnaires over the course of the day on mobile devices. This method maximizes ecological or real-world validity while minimizing recall bias. In combination with passively tracked GPS based mobility data, EMA allows us to collect detailed information on health risk behaviors in the daily lives of individuals. This presentation will provide an overview of research my collaborators and I have conducted using these methods, and an ongoing study that uses EMA and GPS data to inform smoking cessation intervention delivery via smartphones.
