of the unidimensional finding for alcohol use disorders beyond community samples. These samples included patients that have been characterized as heavy chronic and acute drinkers[28;29]and, indeed, have a much higher prevalence of both alcohol use disorders and endorsement of alcohol use disorders symptoms than that reported in community samples, but lower than that reported in a clinical sample of adolescents in alcohol treatment[25] and under clinical treatment[26;27]. The cross-national nature of our sample widens the applicability of this conclusion and supports a unitary diagnosis of DSM alcohol use disorders that goes beyond a U.S. or English speaking milieu.
