Results: All participants had some familial history of breast cancer, but none had a family history indicative of autosomal dominant genetic mutation. At baseline over three fourths of the sample judged themselves to be appropriate candidates for testing. By the end of the survey, two thirds (70%) of the women in the counseling group still judged themselves to be appropriate candidates for testing. Findings were similar for interest in genetic testing. Changes in beliefs about genetic testing (e.g., beliefs about potential stigma associated with testing) altered the effects of counseling.
Conclusion: These results indicate that counseling can change interest in genetic testing only slightly and that changing women’s beliefs about the properties of testing might be one mechanism of doing so.
