(OR = 1.53, 95 % CI = 0.67 – 2.39) and 3 or more DUIs (OR = 1.88, 95 % CI = 0.81 – 2.95) did not differ in rates of endorsement (X2 (1) = 0.45, p = 0.50) but individuals with 1 DUI (OR = 0.55, 95 % CI = 0.15 – 0.94) were less likely to endorse this criterion than those with multiple DUIs (X2 (1) = 14.94, p = .0001). Because this was the only criterion showing differential endorsement by number of DUIs, and because nearly all individuals with 2 or more DUIs endorsed it (95.6 %), we elected to use the more parsimonious model of DUI status as binary (yes/no). A 4-group model was thus used to test whether measurement characteristics for the 9 AUD criteria differed across men with and without DUIs and women with and without DUIs.
