As shown in Table 3a, significant differences in mean scores between Whites and Blacks were observed for all four density measures. Specifically, across all density measures, Whites (vs. Blacks) had higher mean scores. On the other hand, no significant difference in the proportions of FH+ between Whites and Blacks were observed for FHFather–AUDDx and FHMother–AUDDx measures. However, a significantly greater proportion of Whites (vs. Blacks) were FH+ on FHParent–AUDDx and FHFirst–AUDDx dichotomous measures.
