New study tackles stigma and shame to help people with HIV and addiction get healthy
NCT ID NCT05934305
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a 5-session virtual program called MATTER for 256 people living with HIV and substance use disorders in Boston and Miami. The program uses text messages and coaching to help people manage shame and stigma, set health goals, and stay connected to HIV care. The goal is to see if it helps more people achieve an undetectable viral load, which keeps them healthy and prevents spreading HIV.
