What this trial studies

This intervention focuses on men who have sex with men (MSM) and gender minority individuals living with HIV and substance use disorders (SUDs). It aims to improve viral suppression by addressing internalized stigma and shame through a 5-session text-enhanced psychobehavioral intervention called MATTER. The study will assess the efficacy and implementation of this intervention in two different locations, Boston and Miami, to understand the facilitators and barriers to engaging in HIV care. Participants will receive support in developing self-care goals and increasing their self-efficacy to manage their health better.

Who should consider this trial

Good fit: Ideal candidates include HIV-positive MSM or gender minority individuals with substance use disorders who experience internalized stigma and have an unsuppressed viral load.

Not a fit: Patients who are cisgender women or cisgender heterosexual men will not benefit from this study.

Why it matters

Potential benefit: If successful, this intervention could significantly improve health outcomes for MSM and gender minority individuals living with HIV and SUDs by enhancing their engagement in HIV care.

How similar studies have performed: Other studies have shown success in addressing stigma and shame in similar populations, indicating that this approach has potential for positive outcomes.
