Additional exploratory examination of individual differences by cluster analysis revealed three clusters that best described the relationship of baseline alcohol responses to future AUD symptoms (Figure 2). Among half the participants (n = 51), increasing levels of stimulation and liking were predictors of more AUD symptoms; the remaining half included clusters with increasing levels of liking and wanting more (n = 25) or wanting more alone (n = 28) as significant predictors. The cluster groups did not differ on age, sex, race, education, FH, or absolute number of AUD symptoms.
