Couple-Based Motivational Interviewing With Mobile Breathalyzers to Reduce Alcohol Use in South Africa

December 18, 2023 updated by: University of California, San Francisco
This project aims to develop and pilot test an intervention using couple-based motivational interviewing (MI) and mobile breathalyzers to reduce heavy alcohol use with couples living with HIV in South Africa.

Study Overview

Detailed Description

This project aims to develop and test an alcohol intervention using couple-based motivational interviewing (MI) and mobile breathalyzers to build dyadic support around drinking in HIV-affected couples in South Africa. Specifically, the study aims to: 1) To develop a couple-based MI intervention with mobile breathalyzer technology to deliver real-time feedback on BAC levels. We will target heavy alcohol users with HIV and enroll their primary partner; 2) to develop and pilot test the study procedures for a future randomized controlled trial (RCT) of the couple-based intervention; and 3) to determine the feasibility and acceptability (F&A) of couple-based MI as a standalone intervention and when combined with mobile breathalyzers to provide real-time feedback and support to couples. We will also conduct qualitative interviews with a subset of 15 couples to contextualize F&A data and refine our procedures. Our goal is to demonstrate a proof-of-concept for the proposed intervention, which if shown to be feasible and acceptable, may provide a scalable intervention to reduce heavy alcohol consumption and improve HIV treatment outcomes for couples in South Africa.

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  • in a primary relationship for at least 6 months
  • aged 18-49
  • have at least one partner (the "index patient") with a positive AUDIT-C screen score
  • has been on antiretroviral therapy (ART) for at least 6 months
  • has disclosed HIV status to their partner

Exclusion Criteria:

How is the study designed?

Design Details

  • Primary Purpose: Supportive Care
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
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.
Counseling
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.
Counseling
Counseling plus mobile breathalyzer/ app
