The Partnership for Maternal, Newborn and Child Health (PMNCH) and the World Health Organization (WHO), in collaboration with partners, identified a need to integrate social, behavioral, and community engagement (SBCE) interventions into national health policies, services, and programs. To address this, ThinkWell developed an investment case to scale SBCE interventions for reproductive, maternal, newborn, adolescent and child health (RMNACH). Our work included a scoping exercise to gather key stakeholders’ insights related to the investment case’s scope, approach, and target audience. The BBC Media Action, in collaboration with the WHO, organized a meeting for public health and communication partners to discuss strengthening investment in SBCE interventions. ThinkWell served on the discussion panel.
