YPLWH (N = 160, 136 after 15% attrition, 18-29 years of age, estimated to include 73% male, 26% female, 1% transgender, 70% racial and ethnic minorities) will be asked to wear a wrist alcohol biosensor (BACtrack Skyn) for 30 days and report their alcohol use using daily ecological momentary assessment (EMA). A subset of the sample will also be assigned to use an app called the eWrapper app that is a game app designed to promote engagement with the Skyn sensor via reciprocity and personalized feedback.
