More than 70% of each ethnic group stated that they would be willing to participate in genetic research. There were no significant differences between groups [χ2 (2)λ=λ1.66, Pλ=λ0.437]. Table 2 shows the within-group comparisons across demographic, clinical, and research characters by willingness to participate in genetic research. For all the three ethnic groups, willingness to participate was not significantly associated with age, marital status, history of mental illness or treatment seeking, knowing friend/family member who had mental illness, and volunteering for health research in the past. Among Whites, significantly more females (89%) than males (69%) stated that they would be willing to participate. The percentage of Blacks willing to participate increased with education, with 79% of college-educated or higher, 70% of high school graduates, and 53% of those less than high school educated being willing to participate.
