Co-Developing a Women-Centered HIV Prevention Intervention to Reduce Stigma, Increase HIV Self-Testing, and Improve Pre-Exposure Prophylaxis (PrEP) Uptake in Ghana (WISE WOMAN): A Study Protocol

Background: Young women in Ghana (18-35 years) remain disproportionately affected by HIV due to intersecting structural and social challenges, including stigma, gendered power dynamics, and limited access to women-centered prevention services. Although HIV self-testing (HIVST) and pre-exposure prophylaxis (PrEP) are effective biomedical prevention strategies, uptake among young Ghanaian women remains low. Barriers include limited awareness, persistent stigma, and a lack of culturally relevant, youth-responsive prevention approaches. The WISE WOMAN study aims to address these gaps by developing and piloting a women-centered HIV prevention intervention co-created with young women in Ghana. Methods: This protocol describes a pilot implementation study of a women-centered HIV prevention intervention that will be delivered via WhatsApp. The intervention is informed by community-based participatory research and human-centered design approaches to enhance cultural relevance and responsiveness to young womens lived experiences. The study will enroll 50 young women aged 18-35 years who will participate in a four-week WhatsApp-based intervention designed to increase HIV prevention knowledge, reduce stigma, and support engagement with HIVST and PrEP. Implementation outcomes, including feasibility, acceptability, and appropriateness, will be assessed using mixed methods. Quantitative data will be collected through baseline and post-intervention surveys, including the PIERS-22 engagement scale, and will be analyzed using descriptive statistics and paired comparisons. Qualitative data from group interactions and post-intervention interviews will be analyzed using thematic analysis. The study has received ethical approval from the University at Buffalo Institutional Review Board (STUDY00009328) and the Ensign Global College Ethics Committee (IRB/EL/AF-02/2025) and is registered at ClinicalTrials.gov (NCT07003789). Discussion: This protocol outlines the design and methods for a digitally delivered, women-centered HIV prevention intervention grounded in participatory approaches. The planned pilot study will generate critical implementation evidence on the feasibility, acceptability, and appropriateness of a WhatsApp-based, co-designed intervention, informing future adaptation, scale-up, and integration of culturally grounded HIV prevention strategies for young women in Ghana and similar settings.
