Arms

  • No Intervention: Enhanced Usual Care
    Couples in this condition will receive the standard of care for alcohol use in addition to a brief alcohol counseling session modeled after WHO guidelines and Dr. Conroy's intervention in Malawi, which uses participants' baseline AUDIT scores for messaging around alcohol reduction and lasts 5-10 minutes.
  • Experimental: Motivational Interviewing (MI)
    Couples will have three MI sessions over a 60-day period. These sessions will focus on communication between the couple, alcohol consumption patterns, and setting goals for alcohol-use reduction.
  • Experimental: Motivational Interviewing Plus Breathalyzer (MI Plus)
    In addition to three MI sessions, drinkers in this condition will be prompted via SMS message twice per day to use a mobile app and a breathalyzer to test their blood alcohol levels (BAC). Both the drinker and their partner will receive real-time feedback about alcohol use.
