CONCLUSIONS
The REACH adherence interventions facilitated PrEP use by providing information about HIV and PrEP, continually motivating participants and supporting them to develop behavioural skills and self‐efficacy. These strategies supported adherence because they were delivered in a youth‐friendly environment with caring, non‐judgemental counsellors; provided frequent opportunities to engage with counsellors and peers and to access additional support and resources; and built trust in products and staff. Retention of these core components in programmatic adaptations of the REACH strategies may help ensure their success in supporting oral PrEP and ring use among AGYW.
