NCT Number: NCT05431855
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.

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.

Inclusion criteria
Exclusion criteria
The eWrapper app includes two engagement strategies (reciprocity and personalized feedback) and implements a micro-randomized trial (MRT) design to test whether the strategies work.
Time frame: 30 days
The percentage of Skyn sensor wearing will be the primary outcome. We will calculate the percentage of time participants wear the sensor during the 30 days, and compare whether this differs between those who have access to the eWrapper vs. those who do not.
Time frame: 30 days
Survey adapted from the System Usability Scale (Brooke, 1986) will be used to assess participant perception of feasibility of wearing the alcohol biosensor. This survey was administered at the conclusion of the 30 day trial. Items in the System Usability Scale were measured on a five-point Likert scale from 1-strongly disagree to 5-strongly agree. The Mean score was calculated to form a total scale score, with a higher number indicating higher overall usability/acceptability. No subscale scores were calculated.
