Interviewed Subjects were placed into outcome categories using guidelines similar to those used in several recent follow-ups (Gonçalves et al., 2017; McCutcheon et al., 2017). Group 1 (Low-Risk Drinking) consumed alcohol the prior year, using quantities that never exceeded three standard drinks (about 12 grams of ethanol) per day and 13 drinks per week, and denied two or more alcohol problems in the prior five years. Group 2 (High-Risk Drinking) in the past year had at least one occasion where they exceeded the Low-Risk Drinking guidelines but denied two or more alcohol problems in the prior five years. Group 3 (Problematic Drinking) admitted to two or more alcohol problems in the prior five years, and Group 4 (Abstinent) reported no alcohol consumption in the year prior to follow-up and denied having two or more alcohol problems in the prior five years.
