Abstract
Objective: Developing targeted, culturally competent educational materials is critical for participant understanding of engagement in a large genomic study that uses computational pipelines to produce genome-informed risk assessments. Materials and Methods: Guided by the Smerecnik framework that theorizes understanding of multifactorial genetic disease through 3 knowledge types, we developed English and Spanish infographics for individuals enrolled in the Electronic Medical Records and Genomics Network. Infographics were developed to explain concepts in lay language and visualizations. We conducted iterative sessions using a modified “think-aloud” process with 10 participants (6 English, 4 Spanish-speaking) to explore comprehension of and attitudes towards the infographics. Results: We found that all but one participant had “awareness knowledge” of genetic disease risk factors upon viewing the infographics. Many participants had difficulty with “how-to” knowledge of applying genetic risk factors to specific monogenic and polygenic risks. Participant attitudes towards the iteratively-refined infographics indicated that design saturation was reached. Discussion: There were several elements that contributed to the participants’ comprehension (or misunderstanding) of the infographics. Visualization and iconography techniques best resonated with those who could draw on prior experiences or knowledge and were absent in those without. Limited graphicacy interfered with the understanding of absolute and relative risks when presented in graph format. Notably, narrative and storytelling theory that informed the creation of a vignette infographic was most accessible to all participants. Conclusion: Engagement with the intended audience who can identify strengths and points for improvement of the intervention is necessary to the development of effective infographics.
