Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are HIV-negative transgender women aged 18-29 who have a recent history of condomless sex and are either not on PrEP or are non-adherent.

Probably not a fit

Patients who are HIV-positive, have serious cognitive or psychiatric issues, or are currently enrolled in another HIV intervention study may not benefit from this study.

What this trial studies

This project aims to develop a multi-component, technology-delivered intervention that targets HIV and intersectional stigma while enhancing the use of HIV pre-exposure prophylaxis (PrEP) among HIV-negative young transgender women aged 18-29 in Thailand. The intervention includes Mobile Healthy Choices (mHC), Finding Respect and Ending Stigma around HIV (FRESH), and standard PrEP counseling. By utilizing mobile health technology, the study seeks to create a supportive environment that encourages PrEP adherence and reduces stigma associated with HIV.

Why it matters

Potential benefit: If successful, this intervention could significantly increase PrEP uptake and adherence among young transgender women, thereby reducing their risk of HIV infection.

How similar studies have gone: Other studies have shown success in using technology-based interventions to improve health outcomes in similar populations, indicating a promising approach.
