Before genetic testing becomes widely available in Iceland it is important to understand what motivates women s interest in undergoing testing as that will provide the data necessary for designing effective counseling interventions. Therefore, the aim of this population-based study was to examine interest in and predictors of interest in genetic testing among Icelandic women. Material and methods: A randomly selected sample of 534 Icelandic women, who had not been previously diagnosed with breast cancer, completed questionnaires assessing, demographic/medical variables, interest in genetic testing, perceived risk of carrying mutations in BRCA1/2 genes, cancer-specific distress and perceived benefits and barriers of genetic testing. The mean age was 53.8 years and 197 of the women had at least one first degree-relative that had been diagnosed with breast cancer. Results: Interest in testing was high with 74% of the women indicating that they were interested in testing. Family history of breast cancer was unrelated to interest in testing whereas perceived risk of being a mutation carrier was significantly and positively related to interest in testing. Interest in testing was also significantly higher among younger women and among women with higher levels of cancer-specific distress. The most commonly cited reasons for wanting to be tested were to increase use of mammography screening and to learn if one s children were at risk for developing cancer. The most commonly citied reasons against being tested were fear of being mutation carrier and worry that test results would not stay confidential. Conclusions: These results suggest that demand for genetic testing, once it becomes commercially available, among Icelandic women may be high ...
