In this study we identified a small group of heavy-drinking, alcohol-dependent college students whose behavioral undercontrol traits (impulsivity and aggressiveness) might put them at increased risk of alcohol problems after graduation (i.e., they may not “mature out” of drinking). A second group of heavy drinking students was identified who will likely face some level of risk, but at the same time seem more likely to “mature out” of heavy drinking. The similarity in alcohol consumption patterns between the two highest severity classes may be the reason that binge drinking did not improve the model fit when added as an additional criterion to the DSM-IV AUD criteria.
