After we completed the second round of coding, we obtained modest inter-rater agreement on the first three domains, with 68% inter-rater agreement for beliefs about causes of psychiatric disorders, 85% agreement for understanding of genetics, and 64% agreement for understanding of genetics research. Because of time constraints, no further coding sessions were held, and therefore, in computing the aggregate and relative distribution of codes for these domains, we selected only responses for which raters showed complete agreement. This resulted in a total of 63 coded responses for “Causes of Psychiatric Disorders,” 28 coded responses for “Understanding of Genetics,” and 32 coded responses for “Understanding of Genetic Research.”
