Incremental validity evidence for the ASQ was obtained in models comparing ASQ scores and typical alcohol use (AlcQF) as predictors of subjective effects. In each of these models, ASQ scores outperformed AlcQF and contributed substantially to model prediction over AlcQF alone, providing direct evidence that the ASQ assesses meaningful variability in alcohol sensitivity beyond what is accounted for by alcohol involvement. Interestingly, AlcQF provided better prediction of stimulation compared to the SRE, likely reflecting the lack of stimulation-related items on that measure.
