Abstract

Abstract: Disparities in genetic cancer risk assessment (GCRA) uptake persist between Latinas and Non‐Hispanic Whites. This study utilized a mental model approach to interview 20 Latinas (10 affected, 10 unaffected) at increased risk for hereditary breast and ovarian cancer (HBOC). Participants were asked about their knowledge and perceptions of GCRA, HBOC, risk, benefits, motivators, barriers, challenges, and experiences with GCRA. Using the Consensual Qualitative Analysis Framework, two authors independently coded the interviews and applied the final codes upon consensus. Additionally, interviews were coded to identify whether participants spontaneously brought up certain topics without a prompt. Findings identified multiple barriers and facilitators to GCRA uptake in this population, including patient level psychosocial/cultural factors (e.g., limited knowledge, worry about relatives' risk) and healthcare system factors (e.g., receiving no referrals). There were notable differences in awareness and knowledge between affected and unaffected women (e.g., genetic testing awareness), as well as knowledge gaps that were evident in both groups (e.g., age of diagnosis as a risk factor). To reduce disparities in GCRA uptake, interventions should address identified facilitators and barriers. Differences in knowledge and awareness between affected and unaffected women support the development of targeted interventions that address specific knowledge gaps.
