The intent of this pilot is to test the feasibility and acceptability of a real-time ecological momentary assessment (EMA) protocol using self-report electronic surveys for adults with serious mental illness (SMI). We propose using EMA through mobile phone technology to better understand health behaviors of 30 participants currently enrolled in behavioral health services. EMA is a real-time data capture strategy, which allows participants to report their current mood, mental health symptoms, activity, location, and social surroundings at any particular moment. Establishing feasibility will support a larger study of health behaviors of adults with SMI
