- Abstract
Purpose: Our objective was to apply a user-centered design process to identify phrases, graphics, and ways of communicating numerical risks that could be used to help patients understand their cancer risk and next steps on receiving BRCA1 genetic test results (positive, negative, and variants of uncertain significance)., Methods: The first phase of the study, a user-centered design process, consisted of 4 rounds of interviews (N = 42, including 13 health care professionals and 16 patients having undergone BRCA testing). The second was a randomized, between-participants experimental study of 456 United Kingdom residents that compared the resulting reports to reports used in a United Kingdom national genomic laboratory hub. Outcomes were subjective and objective comprehension, communication efficacy, actionability, and perceived risk., Results: Subjective comprehension, communication efficacy, and actionability were all higher for the user-centered reports, with no difference in perceived risk. Comprehension of participants viewing user-centered reports was significantly better on 2 items, directionally (but not significantly) better on 6 items, and directionally (but not significantly) worse on 2 items., Conclusion: Our results imply that user-centered design is a promising approach for developing materials about complex genetic risks. We suggest wordings that are likely to lead to improved comprehension when communicating BRCA-associated risks., Competing Interests: Conflict of Interest The authors declare no conflict of interest.
