This report presents the findings of a global survey of 309 violence against women and girls (VAWG) stakeholders, including practitioners, policymakers, researchers and activists. The anonymous online survey was completed between August-September 2014, with the link sent out through various VAWG networks, listservs and Twitter contacts. The survey aims to help the What Works to Prevent Violence programme learn how best to communicate findings to key stakeholders, by generating information on knowledge and understanding of primary prevention and perceived barriers to evidence-based prevention. These findings will be used to directly inform and advance the What Works to Prevent Violence communications and research uptake strategies.
