Study 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.
