Summary

In this study, participants will be asked to wear a wrist alcohol biosensor for 30 days and report alcohol use using a ecological momentary assessment (EMA) app. A subset of the sample will be micro-randomized to test two engagement strategies--reciprocity and personalized feedback via the eWrapper app to promote their engagement with the biosensor.
