Our results should be interpreted in the context of four main limitations. First, although our sample is racially diverse, it is a college sample, and the results may not generalize to non-college attending emerging adults. For example, college-attending young adults tend to be lower on dimensions of impulsivity (Fromme & Quinn, 2011) but tend to drink more (Slutske et al., 2004) than their non-college attending peers, suggesting that individuals who select into a college environment may differ from the larger population of emerging adults. Second, we rely on self-report, and in some cases, retrospective, measures. The results may be different if independent sources of information (e.g., parents' own reports of their alcohol problems) were available. However, we note that the rates of parental alcohol problems reported by participants using our one-item measures (26%) map well to those reported in the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC) (21%), which used the highly reliable parental history module of the Alcohol Use Disorder and Associated Disabilities Interview Schedule (Thompson, Lizardi, Keyes, & Hasin, 2008). Third, although our sample as
