Mesman 699 alcohol use and alcohol-related problems in a sample of college students while controlling for effects of antisocial behavior. The hypotheses of the study were partially sup- ported. Results indicated that inattention was related to alcohol-related problems even when controlling for antiso- cial behavior, though hyperactivity/impulsivity was not related to alcohol-related problems when controlling for antisocial behavior. This finding is especially noteworthy given the strong relation between antisocial behavior and alcohol use in college students. Thus, the findings suggest that inattention may be an important factor related to alco- hol-related problems in college students. However, neither inattention nor hyperactivity/impulsivity was related to alcohol use regardless of whether antisocial behaviors were controlled. The results from this study extend the findings from a few other studies that also have found a relation between ADHD and alcohol use. For example, Blase et al. (2009) found that self-reported ADHD was predictive of alcohol use, and Heiligenstein and Keeling (2009) reported that ADHD diagnosis was related to alcohol abuse. However, neither of these studies controlled for current behavioral problems, a confounding variable that is related to ADHD and alcohol use. The findings of this study are most con- sistent with the results of Glass and Flory (2012) who also found that inattention was predictive of alcohol-related problems even while controlling for childhood Conduct Disorder symptoms. Thus, this study provides additional support that a continuous examination of ADHD symp- toms, especially inattention, may be important when exploring the relation between ADHD symptoms and alcohol-related problems. Existing literature exploring the different and overlap- ping characteristics of ADHD, Predominantly Inattentive Type and ADHD, Combined Type suggests that the sub- types have different comorbid conditions (Milich, Balentine, & Lynam, 2001). Children with ADHD, Predominantly Inattentive, are more likely those with ADHD, Combined to have internalizing disorders such as depression and anxiety (Weiss, Worling, & Wasdell, 2003), and internalizing disor- ders in college students have been found to be related to alcohol use (Fenzel, 2005; Miller, Miller, Verhegge, Linville, & Pumariega, 2002; Weitzman, 2004). In addition, in a sample of college students, inattention, but neither hyperactivity nor impulsivity, was related to academic dif- ficulty (Frazier et al., 2007). In turn, academic difficulty has

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
