Project Engage: A Wrist Biosensor-based mHealth Suite to Support Alcohol Intervention in Young People Living With HIV

Study Overview
=================
Brief 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.

Detailed Description
-----------------
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 micro-randomized twice daily to test two empirically-based engagement strategies - reciprocity and personalized feedback. Data from the 30-day MRT will be used to (a) develop and validate the algorithm for alcohol detection based on Skyn data; and (b) address scientific questions concerning which engagement strategy works best, for whom and under what conditions in terms of facilitating proximal engagement in biosensor wearing. We will also collect alcohol biomarker (i.e., PEth) at 1-month follow up.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Engagement in biosensor wearing<br>A subset of the participants will receive the same interventions, namely the reciprocity messages, personalized feedback, or no prompt (as control condition), using micro-randomization procedure that randomly assign one of the condition in the morning and one of the condition in the evening. | Behavioral: eWrapper-Engagement strategies to facilitate alcohol biosensor wearing<br>* We will conduct a 30-day micro-randomized trial (MRT)--a clinical trial design for developing and optimizing mHealth interventions to test which engagement strategy works better, for who, and under what condition. A subset of the participants will be micro-randomized in the morning and in the evening, to either a prompt delivering non-contingent small reward (reciprocity); or a prompt containing feedback on self-monitoring progress based on dynamic self-regulation theories (personalized feedback); or no prompt.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Engagement in biosensor wearing | For the whole sample, it is an observational study, so the outcome is just percentage of biosensor wearing during the 30 day period. For the subset who also go through MRT for engagement strategies, we will test the effect of each strategy using % time wearing the sensor in the next 12 hours as the proximal outcome. We hypothesize that the engagement strategies will be better than no prompt and that reciprocity will have an advantage over personalized feedback as it requires less cognitive processing. | Within 12 hours after prompted engagement strategy |
