AB  - OBJECTIVE: The present study examined the dimensionality of DSM-IV Alcohol Use 
      Disorder (AUD) criteria using Item Response Theory (IRT) methods and tested the 
      validity of the proposed DSM-V AUD guidelines in a sample of college students. 
      METHOD: Participants were 396 college students who reported any alcohol use in 
      the past 90 days and were aged 18 years or older. We conducted factor analyses to 
      determine whether a one- or two-factor model provided a better fit to the AUD 
      criteria. IRT analyses estimated item severity and discrimination parameters for 
      each criterion. Multivariate analyses examined differences among the DSM-V 
      diagnostic cut-off (AUD vs. No AUD) and severity qualifiers (no diagnosis, 
      moderate, severe) across several validating measures of alcohol use. RESULTS: A 
      dominant single-factor model provided the best fit to the AUD criteria. IRT 
      analyses indicated that abuse and dependence criteria were intermixed along the 
      latent continuum. The "legal problems" criterion had the highest severity 
      parameter and the tolerance criterion had the lowest severity parameter. The 
      abuse criterion "social/interpersonal problems" and dependence criterion 
      "activities to obtain alcohol" had the highest discrimination parameter 
      estimates. Multivariate analysis indicated that the DSM-V cut-off point, and 
      severity qualifier groups were distinguishable on several measures of alcohol 
      consumption, drinking consequences, and drinking restraint. DISCUSSION: Findings 
      suggest that the AUD criteria reflect a latent variable that represents a primary 
      disorder and provide support for the proposed DSM-V AUD criteria in a sample of 
      college students. Continued research in other high-risk samples of college 
      students is needed.
