Abstract
The aim of the study was to explore distress and health beliefs before and after comprehensive interdisciplinary counseling in families at risk for hereditary non-polyposis colorectal cancer (HNPCC). Results reported here were derived from a consecutive sample of 65 counselees [31 patients with colorectal cancer (CRC) and 34 unaffected at-risk persons] who participated in interdisciplinary counseling provided by human geneticists, surgeons, and psycho-oncologists before genetic testing. Data were collected from self-administered questionnaires before, as well as 4–6 weeks after, counseling. Distress and perceptions specific to HNPCC were assessed at both timepoints using standardized as well as author-derived instruments. Distress declined after counseling, as did worries related to HNPCC. An increase was found in personal belief in control of cancer risk, for instance, in the perceived efficacy of early detection of CRC. We also observed a trend toward greater anticipated ability to cope with a positive gene test after counseling. Changes after counseling were generally more pronounced for persons at risk, as compared to patients with cancer. The decrease in distress was partly attributable to an increase in personal self-confidence. One-third of the sample reported enhanced communication specific to hereditary disease within the family after counseling. A substantial minority, however, said they experienced increased worry and physical symptoms after counseling. Overall, counselees demonstrated less stress and perceived cancer threat as well as enhanced beliefs regarding personal control over cancer, suggesting an overall beneficial impact of comprehensive counseling. Further research is needed to identify those individuals most at risk for increased fear and worry related to HNPCC so that they may be most appropriately counseled.
