Interested in evidence-based criteria for clear communication of public health material? Do you develop and review public health material? Are you interested in enhancing the clarity and ease of understanding of these materials? The Clear Communication Index can help! The U.S. Centers for Disease Control and Prevention developed the Index. How can the Clear Communication Index help you? The Index helps professionals develop and review public health communication materials for clarity, encourages collaboration between writers and reviewers to ensure accuracy, and assesses ease of use of communication materials. The tool consists of criteria that enhance clarity and understanding. Use of the Index yields a quantitative score based on assessment of seven areas: main message and call to action, language, information design, state of the science, behavioural recommendations, numbers, and risk. A widget is available for placement on webpages. This webinar includes an overview of the Index by its developers, followed by a presentation from the National Resource Center for Lupus in the Lupus Foundation of America.
