Note. Implicit Drinking Identity was measured using the Brief Implicit Association Test. Higher scores = stronger identification with drinking. Explicit Drinking Identity was measured using two semantic differential items. Higher scores = stronger identification with drinking. Coefficients are exponentiated. In the count portion of the model, the coefficients can be interpreted as the factor change in the Alcohol Use Disorder Identification Test (AUDIT) associated with a one-unit increase in the predictor. In the inflation portion of the model, the coefficients are odds-ratios and are interpreted as the factor change in the odds of being the always zero group associated with a one-unit increase in the predictor.
