Trauma-focused writing plus rewards to help women who inject drugs stick with PrEP

Official title: Efficacy of a Trauma Intervention for Affect Regulation, Adherence, and Substance Use to Optimize PrEP for Women Who Inject Drugs

Funded at Drexel University · NIH-11324505 · Data updated 2026-11-12

A trial tests whether adding a trauma-focused expressive writing session to a rewards-based program helps women who inject drugs use PrEP more consistently and reduce HIV risk.

Who could benefit from this research

Could help

Women who inject drugs starting PrEP and at risk for HIV acquisition.

Less likely to help

Participants not engaging in PrEP or without adherence challenges may see limited benefit.

What this research studies

This study enrolls 240 women who inject drugs and are starting PrEP at a low-barrier clinic in Philadelphia. Participants are randomized to receive either expressive writing focused on trauma plus contingency management or neutral writing plus contingency management, with follow-up to see who has higher PrEP adherence and lower HIV risk behaviors. The intervention aims to address trauma and substance-use factors that make adherence harder, using objective measures to track PrEP use and abstinence from stimulants and opioids. If successful, the approach could be feasible to implement in real-world PrEP programs serving WWID.

Why it matters

Potential benefit: If effective, this approach could help WWID maintain PrEP adherence and reduce HIV transmission.

How similar studies have gone: Prior work supports combining behavioral interventions with PrEP to improve adherence, but this specific trauma-focused writing plus contingency management approach is novel.
