NDEP Plain Language Review Process

The NDEP creates a variety of materials to help people learn how to prevent type 2 diabetes or manage diabetes to prevent other health problems. Health-related terms and concepts, especially when it comes to the management of diabetes, can be hard to understand. The NDEP works to create materials that use principles of plain language and health literacy.

Reviewed for Plain Language Principles

The NDEP Plain Language Approach

The NDEP’s approach to apply principles of plain language in the development of materials include the following steps:

  • Materials Assessment – NDEP uses the Suitability Assessment of Materials (SAM) tool to evaluate materials. The SAM tool helps rate how hard it is to read words and understand their meaning based on the following criteria:
    • Content – Materials have a clear purpose and focus on behaviors that support the objectives of the piece and that the reader can accomplish.
    • Literacy Demand – Materials follow plain language principles and the reading level matches the reading skill level of the target audience.
    • Graphics and Layout – Graphics and images communicate the main messages or purpose of the content. Fonts are clear and consistent.
    • Learning Stimulation and Motivation – Content is meaningful and appealing to the reader. Specific behaviors that audience members can perform are suggested.
    • Cultural Appropriateness – Cultural context and concept association are used to make messages relevant, understandable, and meaningful to the audience. When appropriate, NDEP materials are tailored for different ethnic populations and messages are matched to the audience, language, experience, and cultural beliefs of the target audience. Materials use positive and culturally diverse images and symbols.
  • Health Numeracy Assessment – NDEP reviews content to find ways to limit or simplify numeric concepts.
  • Technical Review – NDEP shares draft materials with subject matter experts who verify the accuracy of scientific information and behavior change messages.
  • Readability Testing – NDEP uses the Fry and SMOG readability formulas to assess reading levels of materials.
  • Field/Audience Testing – NDEP pretests content, images, and layout of each publication with members of the intended audience.
