The 4 Youth by Youth Project: a Pragmatic Stepped-wedge Cluster Randomized Controlled Trial to Expand Youth-friendly HIV Self-testing Services in Nigeria

Following the completion of the open contests and apprenticeship training, four youth teams (with four distinct interventions) were selected to undergo a one-year pilot assessment in the community. Preliminary findings from the feasibility study suggest that the youth-developed interventions have the potential to impact HIV testing as well as uptake of sexually transmitted infections (STI) testing among young people in Nigeria. As a result, the investigators identified key components from the four interventions to form a single intervention that will be evaluated in the next phase of the research. Thus, the current protocol is focused on evaluating the effectiveness of a combined, youth-developed intervention on HIV testing and other HIV prevention outcomes (i.e. condom use, PrEP referral, STI testing).

Using a stepped-wedge cluster randomized controlled trial design, the I-TEST intervention package will be implemented sequentially across 32 local government areas (LGA) whereby each LGA will be exposed to a pre-intervention (control), intervention (implementing the intervention), and post-intervention condition, according to a randomized schedule. Young people between the ages of 14-24 years will be recruited from the selected 32 local government areas through in-person events, social media platforms, and online advertisements, clinics, and community centers that cater to young people. We included two additional LGAs in November 2021 to account for civil unrest activities that are taking place across two other study sites. Due to the civil unrest, the implementation of the intervention has been affected hence the addition of the two new sites. Upon enrollment, the study team will collect baseline data on HIV testing history, sexual behavior history, youth participation experience, and other related outcomes from the study participants. Two trained youth alongside one trained supervisor will implement the I-TEST intervention at the LGAs.
