This report is part of a package of evidence and tools that includes this systematic review of Communication for Development (C4D) interventions to address violence against children (VAC), an evidence review of randomized controlled trials, a Technical Guidance for C4D programmes addressing VAC, and training materials related to the Guidance. This suite of materials is a result of UNICEF’s investments in C4D capacity and its collaboration with Drexel University to strengthening the evidence-base on what works for preventing and responding to VAC through C4D. Several UNICEF offices are using these resources to develop country roadmaps and strengthen their strategies to address VAC through robust C4D programming. We hope that more UNICEF offices, governments, partner agencies, and others working in this area will find this package useful. We hope that it will also provide the hard evidence that governments and development agencies need for scaling up efforts to reduce violence against children.
