Exploratory factor analysis conducted with the alcohol items identified 2 factors, loadings for which are shown in Table 2. The first factor consisted of items related to alcohol consumption, with the highest loadings (>0.80) for the number of times the participant reporting drinking alcohol and engaging in binge drinking. The second factor consisted of items related to problems associated with alcohol use, with the highest loading on number of times the participant continued to drink even though it was causing problems. Accordingly, we refer to the first alcohol factor as alcohol consumption and the second factor as alcohol problems throughout this manuscript. The correlation between the factors was +0.66.
