Notes: Alcohol problems were measured using the Young Adult Alcohol Problems Screening Test (scores range from 0 to 27) for the exploratory sample and the Young Adult Alcohol Consequences Questionnaire (range 0-42) in the replication sample. Different superscripts indicate clusters that are significantly different from other clusters in the same sample at p < .05.
