Abstract

This is the first study to examine whether cell phones could be used to collect ecological momentary assessment (EMA) data with homeless crack cocaine-addicted adults in treatment. The study adapted an EMA method to examine behavior in real time using cell phones and computer-automated telephone interviewing. Participants treated in an intensive outpatient treatment program were given cell phones for a 2-week period to record current states of cocaine craving and using episodes. Results showed cell phone technology could reliably deliver a computerized survey; this homeless population would use a cell phone to report craving and using episodes, and drug use reported via EMA was in agreement with urine toxicology results for 73% of participants. Of 30 participants, 24 (80%) completed the full 2-week protocol. Participants indicated the survey made them more aware of phenomena leading to cravings and use, suggesting the usefulness of EMA as a potential intervention.
