The research aims to address the issue of Intimate Partner Violence (IPV) in South Asia with a particular focus on adolescence and young adulthood. We investigate the ways in which both community-level social norms and broader political economic factors influence the tendency to perpetrate IPV as well as the efficacy of existing programme approaches to address it. The research programme comprises global and country-specific literature reviews, a multi-level quantitative analysis and qualitative and longitudinal data collection done through a research consortium.
