ABSTRACT
PURPOSE: To determine if the developed Know Your Risk (KYR) intervention is similar to conventional genetic counseling; we evaluated participants’ knowledge of cancer genetics, breast cancer risk perception, attitudes about genetic counseling and testing, and satisfaction with genetic counseling.
METHODS: Women (n = 866) who screened at elevated risk for breast cancer were randomized to the KYR intervention or conventional genetic counseling (2022-2024). The KYR intervention included a series of online pre-test educational videos, direct access to genetic testing, and patient preference for receiving post-test genetic counseling. Participants completed surveys at baseline and after genetic counseling and testing. Non-inferiority hypothesis testing compared the two participant groups.
RESULTS: The mean knowledge score (range 0-12) increased in both study groups from a baseline mean of 6.87 (standard deviation (SD) = 2.46) to 8.66 (SD = 2.16) for the KYR intervention and 8.56 (SD = 2.14) for conventional counseling. Additionally, statistical analyses suggest the non-inferiority of the KYR intervention for participants’ accuracy of their breast cancer risk, attitudes about genetic counseling and genetic testing, and satisfaction with genetic counseling compared to participants randomized to conventional genetic counseling.
CONCLUSION: Findings support that the components included in the KYR intervention are non-inferior for cancer genetic knowledge, risk perception, genetic counseling and testing attitudes, and genetic counseling satisfaction among women who screen at elevated risk for breast cancer. By using the combination of components included in the KYR intervention, genetic counseling and genetic testing are more accessible, convenient, and patient-driven.
