Communicating the impact of the Certified Community Behavioral Health Center Transformation (CCBHC) model is essential for building stakeholder awareness and support. This toolkit, developed via the CCBHC Transformation (CCBHC-T) Initiative, helps state teams develop clear, consistent messaging by identifying key audiences, organizing data and stories, crafting stakeholder-specific messages and planning communication activities. Designed for teams overseeing CCBHC design, development and implementation, the toolkit provides practical prompts and tools to help states tell the story of how CCBHCs are improving access to high-quality behavioral health care.
