Encouraging but limited research indicates that brief motivational interventions may be an effective way to reduce heavy episodic drinking in college students. At 2 campuses, students (83% male) mandated to a substance use prevention program were randomly assigned to 1 of 2 individually administered conditions: (a) a brief motivational interview (BMI; n = 34) or (b) an alcohol education session (AE; n = 30). Students in the BMI condition reported fewer alcohol-related problems than the AE students at 3-and 6-month assessments. Trends toward reductions in number of binge drinking episodes and typical blood alcohol levels were seen in both groups. Process measures confirmed the integrity of both interventions. The findings demonstrate that mandated BMIs can reduce alcohol problems in students referred for alcohol violations. Keywords mandated; student; alcohol; college; brief interventionThe search continues for effective and innovative interventions to curtail heavy episodic (binge) drinking. Binge drinking is defined as having five or more drinks in a single occasion for men (four or more drinks for women; Wechsler et al., 2002). Roughly 4 out of 10 college students (including close to half of the men) binge drink at least once every 2 weeks (O'Malley & Johnston, 2002;Wechsler et al., 2002), and negative consequences frequently result from such drinking, including damage to self, others, and property (Perkins, 2002). Educational programs designed primarily to teach students about the risks associated with excessive drinking have frequently failed to achieve desired reductions in alcohol use (Hingson, Berson, & Dowley, 1997;Wechsler et al., 2002). One interpretation of this consistent lack of effectiveness is that risky drinking represents not a lack of knowledge but rather a lack of motivation to change. Therefore, interventions that enhance motivation for risk reduction are needed to assist the students who are already drinking heavily.Several published studies indicate that in-person brief motivational interventions (BMIs) lead to reduced drinking in college students (Baer et al., 1992;Borsari & Carey, 2000;Larimer et al., 2001;Marlatt et al., 1998;Murphy et al., 2004;Murphy et al., 2001). These BMIs typically consist of one or two 45-min sessions that provide personalized feedback and incorporate motivational interviewing (Miller & Rollnick, 2002). Personalized feedback is designed to engage students and heighten the self-relevance of the educational information; such feedback, when coupled with normative comparisons, develops a sense of discrepancy that can motivate risk reduction. The motivational interviewing style cultivates active collaboration and reinforces self-determination and freedom of choice as participants explore ambivalence regarding current drinking behavior. However, BMIs have yet to be compared with groups that receive sessions of similar length and format.
