Abstract

Clinical evidence supports the value of BRCA1/2 genetic counseling and testing for managing hereditary breast and ovarian cancer risk; however, BRCA1/2 genetic counseling and testing are underutilized among black women, and reasons for low use remain elusive. We examined the potential influence of sociocultural factors (medical mistrust, concerns about genetic discrimination) on genetic counseling and testing engagement in a sample of 100 black women at increased risk for carrying a BRCA1/2 mutation. Eligible participants fell into 1 of 3 groups: (1) healthy women with at least 1 first-degree relative affected by breast and/or ovarian cancer, (2) women diagnosed with breast cancer at age less than or equal to 50 years, and (3) women diagnosed with breast and/or ovarian cancer at age greater than or equal to 50 years with either 1 first-degree relative or 2 second-degree relatives with breast and/or ovarian cancer. Participants were recruited from clinical and community settings and completed a semistructured interview. Study variable relationships were examined using bivariate tests and multivariate regression analysis. As expected, genetic counseling and testing engagement among this sample was low (28%). After accounting for sociodemographic factors and self-efficacy (β = 0.37, p
