Enhancing the readability of materials describing genetic risk for breast cancer

The number of individuals contemplating genetic testing is increasing, but the current materials and overall subject matter remain complex and not easily understood by many. The goal of this project was to evaluate efforts to revise and increase the readability of an existing information packet describing genetic risk for breast cancer.

Evaluation was conducted in two stages through two related studies. In Study 1, a focus group of multiethnic breast cancer survivors was assembled to obtain feedback on images included in the revised breast cancer genetics information packet. In Study 2, African American adult students in a literacy program evaluated the revised images (based on the feedback of the focus group in Study 1) and text of the information packet and provided ratings on readability, format, and appearance.

Responses from Study 1 participants suggested that some of the images created for the packet needed to be clearer in the concepts they were intended to convey. In Study 2, ratings of adult learners suggested difficulty with word comprehension in spite of the inclusion of definitions and a glossary. The reading level achieved was markedly lower than the college reading level required by the original information packet and other patient-directed cancer genetics materials.

Although efforts to clarify written materials in order to better serve patients with low literacy received generally favorable responses, continued efforts to create more user-friendly patient education materials are warranted.
