The Signal-Trial: Evaluation of a Screening Tool for Psychosocial Problems in Cancer Genetics

Background

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.

Aim

The aim of the trial is to evaluate the implementation of a short, self-developed cancer-genetics checklist; the 'Signal-checklist', as an aid in 1) facilitating communication on psychosocial issues during the genetic counseling session, 2) increasing counselors awareness of psychosocial problems of the counselee, and 3) improving the management of these psychosocial problems during and after the process of genetic counselling.

Method

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.
