Note. AA = African American; W = White; H = Hispanic; PTSD = posttraumatic stress disorder. Total did not add up 100% for some variables because of missing values. Significant difference at p < .017; one-way analysis of variances with Bonferroni correction was used to examine “between-groups” differences for continuous variables and chi-square tests were used to examine the differences for categorical variables.
