RESUMO
Approximately 70% of counselees undergoing cancer genetic counseling and testing (CGCT) experience some degree of CGCT-related psychosocial problems. We evaluated the efficacy of an intervention designed to increase detection and management of problems 4 weeks after completion of CGCT. In this randomized, controlled trial, 118 participants completed a CGCT-related problem questionnaire prior to an - audiotaped - telephone session with their counselor 1 month after DNA-test disclosure. For those randomized to the intervention group (n = 63), a summary of the questionnaire results was provided to the counselor prior to the telephone session. Primary outcomes were discussion of the problems, counselors' awareness of problems, and problem management. Secondary outcomes included self-reported distress, cancer worries, CGCT-related problems, and satisfaction. Counselors who received a summary of the questionnaire were more aware of counselees' problems in only one psychosocial domain (practical issues). No significant differences in the number of problems discussed, in problem management, or on any of the secondary outcomes were observed. The prevalence of problems was generally low. The telephone session, combined with feedback on psychosocial problems, has minimal impact. The low prevalence of psychosocial problems 1 month post-CGCT recommends against its use as a routine extension of the CGCT procedure.

BACKGROUND: Up to three-quarters of individuals who undergo cancer genetic counseling and testing report psychosocial problems specifically related to that setting. The objectives of this study were to develop and evaluate the screening properties of a questionnaire designed to assess specific psychosocial problems related to cancer genetic counseling. METHODS: We adopted the European Organisation for Research and Treatment of Cancer Quality of Life Group guidelines to develop the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, a 26-item questionnaire organized into six problem domains: genetics, practical issues, family, living with cancer, emotions, and children. The Distress Thermometer and a question per domain on the perceived need for extra psychosocial services were included as well. We administered the questionnaire and the Hospital Anxiety and Depression Scale to 127 counselees at the time of genetic counseling and 3 weeks after DNA test disclosure. As a gold standard to evaluate the screening properties of the questionnaire, participants underwent a semi-structured interview with an experienced social worker who assessed the presence and severity of problems per domain. RESULTS: A cutoff score representing responses of 'quite a bit' or 'very much' to one or more items within a given problem domain yielded moderate to high sensitivity across domains. A cutoff of 4 on the Distress Thermometer yielded high sensitivity. The questions regarding the perceived need for extra psychosocial services yielded high specificity and negative predictive values. CONCLUSION: The Psychosocial Aspects of Hereditary Cancer questionnaire in combination with the Distress Thermometer can be used as a first-line screener for psychosocial problems within the cancer genetic counseling setting.

Only a minority of individuals who undergo cancer genetic counseling experience heightened levels of psychological distress, but many more experience a range of cancer genetic-specific psychosocial problems. The aim of this study was to estimate the prevalence of such psychosocial problems, and to identify possible demographic and clinical variables associated significantly with them. Consenting individuals scheduled to undergo cancer genetic counseling completed the Psychosocial Aspects of Hereditary Cancer (PAHC) questionnaire, the Hospital Anxiety and Depression Scale (HADS) and the Distress Thermometer (DT) prior to or immediately following their counseling session. More than half of the 137 participants reported problems on three or more domains of the PAHC, most often in the domains 'living with cancer' (84%), 'family issues' (46%), 'hereditary predisposition' (45%), and 'child-related issues' (42%). Correlations between the PAHC, the HADS and the DT were low. Previous contact with a psychosocial worker, and having a personal history of cancer were associated significantly with HADS scores, but explained little variance (9%). No background variables were associated significantly with the DT. Previous contact with a psychosocial worker, and having children were significantly associated with several PAHC domains, again explaining only a small percentage of the variance (2-14%). The majority of counselees experience specific cancer genetic counseling-related psychosocial problems. Only a few background variables are associated significantly with distress or psychosocial problems. Thus we recommend using the PAHC or a similar problem-oriented questionnaire routinely in cancer genetic counseling to identify individuals with such problems.
