An important part of individuals undergoing genetic counseling and/or testing for cancer experience psychosocial problems and worries during or after this process. Approximately 20% of these individuals experience serious problems, such as fear for cancer in themselves or their relatives, family communication problems, unresolved grief, problems in coping with the DNA-test-results, difficulties in choices with regard to DNA-testing, preventive surgeries, and concerns about insurance or work. Research shows that these problems are frequently undetected by the counselors. Within the limited available time of a counseling session, a lot of information should be given to the counselee. This information is mostly biomedical and provider driven. Therefore psychosocial issues can be underexposed. The use of a brief questionnaire, completed by the counselee prior to the counseling session, can serve as a tool for the counselor to screen and address the relevant psychosocial issues in a systematic manner. Therefore, in 2009-2010 the investigators have developed and validated the 'Signal-checklist' to identify relevant psychosocial problems frequently encountered in the cancer-genetics setting, and need for extra psychosocial services. This 'Signal-checklist' can serve as a tool in screening systematically for psychosocial issues, addressing these issues and directing appropriate referrals to extra psychosocial services. The Signal-Trial will be performed to evaluate the use and effectiveness of the checklist.
