This study is a collaboration between the family cancer clinics of the NKI-AVL and the UMCU. Individuals requesting genetic counseling for the high incidence of cancer in their family are invited to participate in the trial. Participants will be asked to complete the 'Signal checklist' prior to their counseling visit. Participants (N=264) will be randomly assigned to one of the two study arms. The intervention group will receive feed-back on the 'Signal-checklist', whereas the control group will not receive feed-back. Three weeks after the DNA-test disclosure session, participants will be asked to complete again the 'Signal-checklist' followed by a telephone call by their counselor. Again, the results of the 'Signal-checklist' will be available to the counselor for participants in the intervention group, but not for the control group. Both the genetic counseling session and telephone call will be audio taped. Furthermore, all participants will be asked to complete three questionnaires on the Internet (or by mail, if preferred); 1) before randomization (3 weeks prior to the counseling session), 2) three weeks after the counseling session, and 3) four months after the potential DNA-test result disclosure. These questionnaires include items on communication during genetic counseling, the need for professional psychosocial support, cancer worries, satisfaction with received care, and experiences with the use of the 'Signal-checklist'. The audio-tapes and completed questionnaires will be used to measure psychosocial problems of the counselees, the awareness of the counselors of these problems, and the management of these problems. Secondary analysis will be conducted to assess the need for extra psychosocial services, satisfaction with genetic counseling, feasibility of implementing the 'Signal-checklist' and decreasing psychosocial problems over time.
