Abstract
Background
Despite the benefits of genetic counseling (GC) and testing, uptake of cancer genetic services is generally low and African American (AA) women are substantially less likely to receive genetic services than non-Hispanic White women. Our team developed a culturally sensitive, narrative decision aid video to promote uptake of GC among AA women at risk for a hereditary breast cancer syndrome. We report here a pilot study to demonstrate feasibility and acceptability of incorporating this intervention in conjunction with population-based cancer risk assessment in a clinical setting with medically underserved AA women.
Methods
AA women recommended for GC based on cancer genetic risk assessment performed in a mammography center were recruited at the time of the mammogram. A prospective, pre-post survey study design, guided by theoretical constructs, was used to evaluate baseline and immediate post-intervention psychosocial factors, including intention to participate in GC and intervention satisfaction.
Results
Pilot recruitment goals were met (n=30). Pre-intervention, 50% of participants indicated that they were extremely likely to make a GC appointment, compared with 70% post-intervention (p=0.0001). After watching the intervention, 50% of participants indicated that the video changed their mind regarding GC.
Conclusions
This study demonstrated cultural acceptability of a decision aid intervention designed to motivate AA women with hereditary breast cancer risk to attend a GC appointment. Our study showed that intention may be a specific and key construct to target in interventions designed to support decision-making about genetic services. Study results informed the design of a subsequent large scale, randomized implementation study.
