Survey respondents often show high interest in undergoing genetic testing for all types of medical disorders (Roberts et al., 2005), including psychiatric disorders, although the data for the latter come primarily from surveys of affected persons and their family members. For example, among family members of schizophrenia patients who had participated in genetic research, DeLisi and Bertisch (2006) reported that 83% would want to be tested if a genetic test for schizophrenia existed. In a mixed group of 90 bipolar patients (many of whom were enrolled in genetic research studies), 85% indicated that they would definitely be tested if a genetic test for bipolar disorder existed, and another 15% said they would probably have the test (80% of their spouses indicated that they would want to be tested too) (Trippitelli et al., 1998).
