The Community Toolbox is a vast collection of free online guides and toolkits for community engagement. The Toolbox is divided into sections on developing particular skills relevant to engagement, many of which translate directly to patient engagement. Each section contains extensive guides, a related toolkit, and a collection of resources. Particularly relevant guides include Communications to Promote Interest and Participation, Building Leadership for Engagement, Group Facilitation and Cultural Competence. The Community Toolbox is available in English, Spanish, and Arabic.
