In predictive DNA testing for hereditary cancer, test results should traditionally be disclosed face-to-face. Increasingly, however, counselees ask to receive their test result at home by letter. To compare the quality of genetic counselling in the traditional way to a procedure in which counselees are offered a choice on how to get their test result. Counselees from families with a known BRCA1/2 or Lynch syndrome mutation were randomised into two groups. The control group was given the DNA test result in a face-to-face consultation. In the intervention group people could choose to learn their test result face-to-face or by letter. The quality of genetic counselling was assessed through questionnaires at three different moments. Data of 198 counselees were analysed. The quality of genetic counselling and psychological functioning were equally good in both groups. The majority of cases chose for disclosure by letter. The counselees with a good test result in the intervention group were the most satisfied. Our results indicate that in predictive DNA testing for BRCA1/2 and Lynch syndrome, a choice protocol is equally safe and more satisfying. Moreover, it is more efficient for both counsellor and counselee.
