BackgroundThe dimensionality and the contribution of the proposed diagnostic criteria for the DSM-5 model of alcohol-use disorders (AUDs) which will provide guidelines for future diagnoses have not been examined in depth.MethodData from past year drinkers in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC), Wave 2 (n = 22 177) were analysed. Severity and discrimination of DSM-5 diagnostic criteria was determined using a two-parameter logistic Item Response Theory model. Comparative analyses were conducted on the DSM-IV criteria. Differential functioning of the criteria across a number of socio-demographic variables was assessed.ResultsThe proposed criteria supported a unidimensional AUD model, with a factor loading range of 0.625–0.914 (craving = 0.818). The model measured intermediate severity of AUDs with ‘reduced time on important/pleasurable activities’ and ‘failure to meet major role obligations’ criteria having the highest severity and discrimination. Craving, endorsed by 4.2% of the general population, was in the mid-range for both severity (sixth) and discrimination (seventh). Significant measurement bias was found on four criteria across socio-demographic subgroups.ConclusionsApplication of the proposed DSM-5 changes yields an improved one-factor model of AUD over the existing DSM-IV model. Inclusion of a craving criterion improves the application of the diagnostic criteria in a general population sample, covering a previously unrepresented problem area. Additionally, criteria measuring the milder end of the AUD continuum remain absent and some criteria exhibit measurement non-invariance. The AUD classification may require further refinement to enhance validity and reliability.
