Trauma-Focused Interventions for HIV Prevention in Women Who Inject Drugs
(TIARAS Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
The goal of this randomized controlled trial is to test the effectiveness of "TIARAS," a trauma intervention designed to reduce HIV acquisition risk among women who inject drugs (WWID). To be eligible for this study, participants must have been prescribed pre-exposure prophylaxis (PrEP), a medication taken to prevent HIV, at Prevention Point Philadelphia, a large harm reduction agency located in Philadelphia (PA, USA), or Courage Medicine, a nonprofit health services clinic located in Philadelphia (PA, USA).Enrollment in this study lasts for 12-months so that we can see if TIARAS reduces HIV risk immediately after the intervention ends and whether these effects last over time. During the first 3 months, participants engage in contingency management (CM), an evidenced-based intervention to reduce drug use and HIV risk. We will use CM to encourage engagement in PrEP care as well as stimulant/opioid abstinence. Also during the first 3-months, participants are randomly assigned to complete expressive writing exercises to address a previously undisclosed trauma or neutral writing exercises. Half of the participants will be assigned to the trauma writing group and the other half will be assigned to the neutral writing group.To understand the impact of TIARAS on HIV risk, we will collect and analyze data from surveys, interviews, and biological specimen during the 12-month study period. Our main questions are:* Does participation in TIARAS reduce HIV risk among WWID?* If observed, how long do beneficial effects last?* How and why do WWID experience benefits from TIARAS?
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, you must be on PrEP (a medication to prevent HIV) to participate.
Is contingency management safe for humans?
How is the Contingency Management treatment unique for HIV prevention in women who inject drugs?
Contingency Management is unique because it uses motivational incentives, like prizes, to encourage positive behavior changes, such as reducing drug use and increasing safe practices, which is different from traditional treatments that may not use rewards as a primary method to promote behavior change.678910
What data supports the effectiveness of this treatment for HIV prevention in women who inject drugs?
Research shows that contingency management, which uses rewards to encourage drug abstinence, can reduce HIV risk behaviors in drug users. Additionally, motivational incentives have been effective in improving treatment engagement and outcomes in substance abuse patients, suggesting potential benefits for HIV prevention in women who inject drugs.12111213
