Promoting Genetic Counseling Among African American Women With a Family History of Breast Cancer

In the United States, carriers of hereditary genetic mutations have up to an 85% risk of developing breast cancer compared to 12% in the general population. Overall uptake of genetic services is generally low, particularly among high-risk African American (AA) women, who carry a disproportionate burden of breast cancer mortality. Further, although testing close relatives of individuals who test positive for a pathogenic variant might curtail breast cancer disparities attributable to hereditary risk, it is unclear how counseled or tested individuals influence their social and familial networks. Using a randomized control trial design, the objective of this research project is to test the effectiveness of a culturally targeted video, previously developed by our research team, on promoting genetic counseling attendance among AA women determined to be at high risk for breast cancer through cancer genetic risk assessment in a clinical setting. This study will also test how psychosocial factors (knowledge, intrinsic motivation, risk perception, and distress) impact the relationships between intervention exposures (video versus brochure) and compare the impact of intervention exposures on diffusion of knowledge about genetic counseling through social network analysis.
