Digital PrEP Micro-Intervention for PWUD in Kazakhstan

This study is a mixed-methods pilot designed to evaluate the feasibility, acceptability, and appropriateness of a brief digital micro-intervention aimed at reducing stigma-related barriers to pre-exposure prophylaxis (PrEP) engagement among people who use drugs (PWUD) in Kazakhstan. Participants will complete baseline and post-intervention surveys and receive structured informational content via Telegram or WhatsApp over approximately 2-3 weeks. The intervention focuses on addressing anticipated stigma, confidentiality concerns, and misinformation that may prevent PWUD from seeking PrEP services. No clinical procedures, medication provision, or biological specimen collection are involved.
