Objective: Although there is evidence to suggest an association between ADHD and alcohol use in college students, results are inconclusive primarily because studies have failed to control for related variables. Thus, this study was designed to systematically compare the relative contributions of inattention and hyperactivity/impulsivity to alcohol use and alcohol-related problems in a sample of college students while controlling for effects of antisocial behaviors. Method: A total of 192 undergraduate college students from a rural Midwestern university received class credit for participating in the study. They completed measures of alcohol use, ADHD symptoms, and antisocial behavior. Results: Hierarchical regressions revealed inattention, but not hyperactivity/impulsivity, was related to alcohol-related problems even when controlling for antisocial behavior. However, neither inattention nor hyperactivity/impulsivity was related to alcohol use regardless of whether current antisocial behavior was controlled. Conclusion: Inattention may be an important factor related to alcohol-related problems in college students. (J. of Att. Dis. 2013; XX(X) 1-XX)
