Introduction. The development of a DNA based diagnostic test has allowed for the genetic screening of many hereditary diseases. In addition to the identification of the deleterious gene, this screening process has led to the recognition of developing illnesses at high risk. In recent years, a number of genes predisposing to an inherited cancer syndrome have been identified.
Our purpose in this study was to determine whether subjects at risk who test for inherited colorectal cancer, are likely to develop a higher level of psychological distress than the norm, taking into consideration the particular history of this familial disease.
The demographic and psychosocial aspects of our population was described using: 1) the State Trait Anxiety Inventory (STAI), 2) the Center for Epidemiologic Studies Depression (CES-D), 3) a perceived risk for the gene carrier, 4) subjective perception of personal vulnerability and 5) the role of the medical status (affected or not), which places the subject in either predisposition or predictive testing.
Results show that our population had a higher predisposition for depressive disorders (chi2=9,3. p=0.002) and a significantly higher state of anxiety (chi2=9,3. p=0.002), prior to genetic counselling, compared with other populations. We found no evidence in the medical status, nor the perceived risk. However, the assessment of one's own personal vulnerability is related to psychological distress.
These results highlight the particular vulnerability of subjects undergoing genetic testing as well as showing the pertinence of proposing psychological help throughout the process of these new specific diagnoses.
