Scoping review of social norms interventions to reduce violence and improve SRHR outcomes among adolescents and young people in sub-Saharan Africa.

Introduction: Despite growing interest, guidance to inform effective social norms interventions that improve adolescents and young people's sexual and reproductive health and rights (SRHR) is needed. Methods: We conducted a scoping review of experimental and quasi-experimental studies of social norms interventions in sub-Saharan Africa. Single and multi-component interventions that included a social norms component and assessed impacts on SRHR outcomes among 10- to 24-year-old adolescents and young people were included. We mapped interventions across eight programmatic strategies and six SRHR outcomes, drawing programmatic insights. Results: Discussion: Integrating gender-transformative approaches such as reflections on gender roles and inequalities, youth sexuality, and gendered power relations, and engaging with reference groups were key to the success of programmes. Effective approaches delivered SRHR information alongside reflections on social norms, and combined participatory methods with a structured curriculum guiding activities led by trained facilitators. Most interventions focused on changing social expectations and awareness, but few reported clear diffusion strategies to ensure the spread of the new norms and behaviours for the expected change. Key evidence gaps identified include integrating implementation research to inform the scale-up and sustainability of effective social norms interventions. Social norms interventions that effectively address the needs of high-risk adolescents and young people are needed.
