This study will validate a wrist-worn alcohol monitor (BACtrack Skyn) in both laboratory and real-life settings.
The overarching goal of this research program is to improve alcohol intervention and eventually related clinical outcomes (e.g., liver function) among HIV+ drinkers through biosensor-assisted intervention. Research shows HIV infection can influence alcohol metabolism (i.e., higher blood alcohol levels), so it's necessary to validate the new alcohol biosensor in HIV+ drinkers rather than in general population. The primary goal of this project, as a step toward the development and evaluation of a biosensor-assisted alcohol intervention, is to validate the newly available wrist worn transdermal alcohol biosensor (BACtrack Skyn). The two specific aims are: (1) To assess validity and reliability of the Skyn biosensor using fixed-dose lab administration of alcohol through comparison with laboratory grade breathalyzer, and (2) To validate Skyn biosensor in daily life using a 2-week ecological momentary assessment (EMA) to compare self-reported drinking and the Skyn derived transdermal alcohol concentration (TAC) readings.

However, due to COVID, not all participants were able to complete the lab sessions. Skyn Monitor Lab Session 1: Participants will be instructed to wear the Skyn wrist-worn alcohol monitor and drink 3 beers over the course of an hour and a half. BrAC will be measured every 15 minutes throughout the session. Skyn Monitor Field Test with EMA App: After Skyn Monitor Lab Session 1, participants will be instructed to wear Skyn monitor for the rest of the day and the following two weeks. Participants will also enter information on each drinking session during the two week time using a mobile-based ecological momentary assessment (EMA) to collect real-time data in daily life. Skyn Monitor Lab Session 2: Participants will be instructed to wear the Skyn wrist-worn alcohol monitor and drink 3 beers over the course of an hour and a half. BrAC will be measured every 15 minutes throughout the session. Participant will also complete device acceptability and usability survey. |

| Primary | Transdermal Alcohol Concentration (TAC) | Here we reported mean and SD of peak TAC in the laboratory sessions and in the field test. | There were nine participants were enrolled but did not complete any study procedures due to various of reasons such as self withdrawal or administrative withdrawal, so only 40 participants had usable data for the outcome measure. Also, not all participants completed all study procedures outlined in the description due to COVID pandemic, n for lab and field data analyses varied according to how many participants completed respective study procedure. | Posted | Mean | Standard Deviation | ug/L | 2 weeks |
