In parallel with the extant literature, we found evidence for a unidimensional structure underlying AUD criteria in the sample as a whole and in individuals with and without DUIs as well. Unidimensionality in the non-DUI group, which was heterogeneous regarding AUD status in that 40% did not meet criteria for alcohol abuse or dependence, further supports the conceptualization of the criteria as representing a continuum. Not surprisingly, individuals with DUIs scored significantly higher on the underlying alcohol severity factor than those without DUIs, underscoring their high-risk status and consistent with their higher mean number of AUD symptoms.
