Writing away HIV risk: trauma therapy boosts PrEP in Drug-Using women
NCT ID NCT05192434
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a program called TIARAS, which combines a reward system for staying drug-free and on PrEP (HIV prevention pills or shots) with expressive writing about past trauma. The goal is to see if this approach lowers HIV risk in women who inject drugs. 219 women from Philadelphia clinics took part over 12 months, with researchers tracking PrEP adherence and risky behaviors.
