ABSTRACT Aims  To evaluate the proposed revisions to the DSM‐IV alcohol use disorder criteria using epidemiological data. Design, setting and participants  Data came from the 1997 Australian National Survey of Mental Health and Well‐Being. The sample consisted of 10 641 participants aged 18 years and over. Measurements  Alcohol use disorders were assessed using a revised version of the CIDI version 2.0. Alcohol use disorders were assessed in all respondents who indicated that they had used alcohol more than 12 times in the previous 12 months (n = 7746). Findings  The proposed introduction of a single alcohol use disorder was supported by confirmatory factor analysis (CFA). DSM‐5 criteria were all indicators of a single underlying disorder. Under DSM‐5, the prevalence of alcohol use disorders would increase by 61.7% when compared with those diagnosed under DSM‐IV. When investigating the most appropriate diagnostic threshold, the 3+ threshold maximized agreement between DSM‐IV and DSM‐5 diagnoses, and produced similar prevalence estimates to those yielded by DSM‐IV. Item response theory (IRT) analyses supported the removal of the legal criterion while provided equivocal results for the craving criterion. Conclusions  Under the proposed DSM‐IV revisions for alcohol use disorders, estimates of the prevalence in the general population would increase substantially. Whereas evidence supports some of the revisions such as a single underlying disorder, others such as the 2+ threshold for diagnosis of alcohol use disorder and the inclusion of a ‘craving’ criterion may be problematic.
