Model fit based on AIC values.

Models AIC value Delta AIC
DSM-IV Categorical AD (A1) 7628.51 –
DSM-IV Dimensional AD (A2) 7625.09 3.42
DSM-IV Dimensional AUD (A3) 7625.09 3.42
DSM-5 Dimensional AUD with craving criterion based on rating of 1 or higher (B1) 7624.74 3.77
DSM-5 Dimensional AUD with craving criterion based on rating of 3 or higher (B2) 7623.88 4.63

Notes. AIC, Akaike's information criterion. Lower values suggest better model fit; delta AIC, number of AIC points difference between the denoted dimensional model and the categorical model (A1); AD, alcohol dependence; AUD, alcohol use disorder.
