Other limitations should be noted. Social and legal problems were combined into a single criterion due to concerns specific to the university where the data were collected. To keep alcohol-related self-reports other than the AUD items to the well-validated three-month time frame often used in undergraduate alcohol research, the binge drinking item was reported in a different time frame (past three months) than the self-report items on the DSM-IV AUD criteria (past 12 months). In addition, this was a convenience sample from introductory-level psychology courses. Samples derived from introductory psychology courses are commonly used in alcohol research though (e.g., Leeman et al., 2009b). Women were disproportionately represented. We reported previously (Beseler et al., 2010) that in this sample, fewer women than men met the weekly binge drinking criterion, however women in this sample tended to drink heavily (41.1% met the weekly binge drinking criterion). We also pointed out in a prior report that men and women in this sample differed on only 1 of the 10 DSM-IV AUD items (Beseler et al. 2010).
