Description
Most mhealth applications send motivational messages without regard to the individual’s current physical or emotional context. Ecological Momentary Assessments (EMA), in contrast, allow for real-time self-reports that can guide more timely and appropriate behavioral interventions. However, many mhealth assessments suffer from poor user adherence. We hypothesize that EMA survey interfaces with appropriate level of media richness improve user adherence and reduce cognitive load. Guided by Media Richness Theory and Cognitive Load Theory, a 3-group (n=90), 12-week randomized experiment will evaluate user engagement and cognitive load of 3 sets of EMA survey interfaces representing 3 different levels of media richness. Our study will determine the effect of media richness on the user engagement and cognitive load in the context of EMA surveys. Insights generated by our study can help interface designers’ in choosing the appropriate media for designing superior EMA survey interfaces.
