The purpose of the current study was to examine changes in frequency of discussion about melanoma preventive behaviors among adults who received melanoma genetic test reporting and counseling and their children and grandchildren, correspondence of frequency of discussion with intentions, and content of discussions. Participants received CDKN2A/p16 testing and counseling (N = 24, 46 % p16-positive). Discussions about preventive behaviors were assessed before testing and 1 and 6 months post-testing. Intentions to discuss preventive behaviors and perceived preparedness to discuss risk were assessed post-testing. Open-ended questions assessed content of reported discussions. Discussion of preventive behaviors declined following test reporting, with more rapid decline reported by noncarriers. There was a large gap between the percentage of participants who intended to discuss preventive behaviors and who then reported discussions 1 and 6 months after counseling. Participants felt prepared to discuss melanoma risk but also suggested resources to facilitate discussions. Genetic test reporting and counseling alone did not sustain discussions about preventive behaviors for a hereditary cancer with children and grandchildren. The gap between intentions to have discussions and reported discussions has implications for augmentation of counseling to support at-risk families' discussions about preventive behaviors.
