^aP-values represent differences between ECA 2t-AUDPs and a) ECA Alcohol-unaffecteds (1 v. 3) and b) ECA VHD/1t-AUDPs (2 v. 3) using χ² tests

^bStatistically significant findings (p<.05) are in bold

^cDSM-IV alcohol dependence (AD) does not distinguish between AD with abuse symptoms and AD without. “AD and abuse” indicates meeting criteria for both

^d4 respondents (2 males, 2 females) in the ECA alcohol-unaffected group were lifetime non-drinkers and were excluded in calculations for past year diagnoses
