Lay Description

UT Health San Antonio is seeking healthy women and men ages 21 and older that drink beer, wine, or mixed drinks to participate in a research study.

  • This study is for adults who are seeking treatment for reducing alcohol use.
  • This study is designed to determine the success in reducing drinking when given an incentive (like money) based on a deposit contract while wearing an alcohol detection monitor.
    • Participation is voluntary and will require you to attend 4 visits over the span of 2 weeks if you are eligible.
    • Participants will be asked to deposit $100 at study entry.
    • Participants will be randomly assigned to either Monitoring Group 1 or Monitoring Group 2.
    • Participants' alcohol use will be monitored using remote alcohol sensors.
    • Participants in Monitoring Group 1 will earn $50 back and a $20 weekly incentive for the absence of heavy drinking (transdermal alcohol concentrations ≤ 0.02 g/dl). Participants in Monitoring Group 2 will earn back $50 of their deposit each week regardless of their drinking the previous week.
    • Participants will also be paid for each visit completed.
  • To find out more, contact Sharon Biju at 210-567-2752. Please leave your name and number and we'll get back to you
