Abstract A11: Development and beta testing of a culturally appropriate research literacy support tool to increase research participation among minority and underrepresented populations

Background: It is documented that inequities in research participation by minority and underrepresented populations limits the progression of personalized medicine for cancer treatment for these groups. A lack of understanding essential information during the consent process and poor physician-patient communication have been noted as two overarching barriers to patients participating in translational, clinical and biospecimen research. To address these major patient barriers, we developed a plain language research literacy support (RLS) tool to improve the consent process and facilitate dialogue between physicians/research staff and patients. We describe the tool9s iterative development process and testing of the developed culturally appropriate RLS tool. Methods: We tested the tool among: 1) patient participants ≥18 years of age, who were able to read and speak English from communities associated with five academic centers in the Midwest and Northeast United States; and 2) eligible recruiters who were employed at an academic center and actively recruiting patients into research. The development process for the RLS tool consisted of two phases: cognitive and beta testing. During cognitive testing, we solicited feedback from patient and recruiter participants about the content and format of the tool including low literacy language, pictures and recommendations for additional content. The tool consisted of concept cards to provide information to assist patients in making an informed decision about participating in research. During beta testing, a condensed version of the tool was tested to assess acceptability and change in knowledge about research participation. Results: Participants included 155 patients (52: cognitive testing phase; 103: beta testing phase) and 20 recruiter participants. Patient participants were mostly females (71%). Self-identified race of patients included: Whites (43%), African Americans (32%), Native Americans (20%), and other (6%). In addition, 23% of patient participants self-identified as Hispanic. During the cognitive testing phase, patient participants reported that the information was clearly laid out and the tool explained the different steps in the recruitment and enrollment process. Patient participants indicated they had learned new information related to randomization, standard of care, coded-information, and biobanking. Although some patient participants acknowledged the cards contained a great deal of information, most reported that the information was essential. Several participants suggested cards be tailored for the Native American population. Recruiters indicated that the cards provided useful information and would assist patients and research staff. During beta testing phase, 98% of participants agreed the information on the cards helped them understand clinical research. After reviewing the cards, 49% of patient participants reported that they would be very likely to participate in research and 32% reported being somewhat likely to participate in research. The majority (61%) of participants indicated that if invited to participate in a research study, they would prefer that the cards would be mailed to them in advance while 34% wanted to review the cards at their medical appointment. Half of the participants preferred accessing the cards on a computer if administered in a video format. Conclusion: The RLS tool was well received among patient and recruiter participants, making it a potentially valuable resource for enrollment of minority and underrepresented patients into health research. The next step will be to test the RLS tool for effectiveness in a randomized controlled trial. Citation Format: Erika E. de la Riva, Rodney Haring, Elisa M.
