Data presented are cross-sectional, and thus a causal relationship between the parents’ alcohol status, the exposure of the offspring to trauma, and associated posttraumatic sequelae cannot be established. The data presented here are intended to highlight the association between parental alcohol status, trauma exposure, and PTSD in a sample of families at an elevated risk for AUD and related disorders, and, where possible due to age cohort and demographic information, make comparisons between prevalence in COGA and other epidemiologic studies on the measures of interest. As many epidemiologic studies do, our data rely on self-report of trauma exposure and symptomatology, in which a measure of subjectivity and recall bias is embedded. The difference in sample size between the White and Black groups is also a limitation, as power to detect statistically significant differences is lower among the smaller sample (N = 1008) of Black youth and young adults compared to White (N = 2396). We attempted to address this issue of power by randomly sampling groups of Whites similar in size to the Black group and rerunning the regressions; we
