ABSTRACT. Objective: Alcohol intoxication has been associated with dating violence perpetration, defi ned here as psychological and/ or physical violence occurring between young adult dating partners. However, little is known about how the individual variability in the level of alcohol intoxication would infl uence dating violence perpetration and how sex and self-regulation might infl uence this association. Method: College-aged men and women (N = 146) from a large southwestern U.S. university completed background questionnaires, including the Brief Self-Control Scale, to assess self-regulation and then reported their dating violence perpetration and alcohol consumption using a 90-day Timeline Followback assessment. Their average estimated blood alcohol concentration (eBAC) and their daily deviation from this average were calculated for each of the 90 days to examine the between-and withinperson effects of alcohol consumption, respectively. Results: Results of a two-level generalized estimating equation suggest that increases in daily eBAC were associated with an increased likelihood of perpetrating dating violence; however, this association was stronger for those who had a low average eBAC compared with those who had a high average eBAC. For those who had a low average eBAC, higher self-regulation was associated with a lower probability of perpetrating dating violence, whereas among those with a high average eBAC, self-regulation was not associated with dating violence perpetration. Sex did not moderate the association between eBAC and dating violence perpetration. Conclusions: Findings highlight the importance of self-regulation in dating violence perpetration-particularly for those with low average eBACs-and the need for varied intervention strategies, depending on one's typical drinking pattern.

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.

To correct for nonnormality due to positive skew, the following variables were square-root transformed: average drinks per week, average BAC and heaviest BAC.BAC for each drinking day reported on the TLFB was calculated by applying the formula outlined by Matthews and Miller (1979) to the data, and then an average BAC across drinking days was obtained.

Interventions designed to reduce heavy drinking among college students often contain suggestions for drinking control strategies. However, little is known about the relationship of the use of these strategies to alcohol consumption. This study developed a measure of drinking control strategies and investigated its psychometric properties in a sample of 250 college drinkers. Strategies clustered into three factors: selective avoidance of heavy drinking activities/situations, strategies used while drinking, and alternatives to drinking. These three types of strategies were independently associated with alcohol use; however, the first and last types were negatively associated with alcohol consumption, whereas the second type was positively associated with alcohol use. The findings from this study suggest that type of strategy recommended may be important when the goal is alcohol reduction. Keywordsdrinking control strategies; alcohol use; college students Surveys of drinking in national samples of college campuses revealed that between 34 to 44% of students met criteria for heavy drinking (Douglas et al., 1997;Wechsler et al., 2002). Heavy drinking can lead to health risks (e.g., blackouts, personal injuries, physical illnesses, and unprotected sexual activity), in addition to academic, interpersonal, and legal problems (Hingson, Heeren, Winter, & Wechsler, 2005;Perkins, 2002;Aertgeerts & Buntinx, 2002). Due to the substantial risks associated with heavy college drinking, innovative risk reduction strategies are needed. Effective intervention programs have combined information, normative feedback and values clarification within a context of teaching college students skills to moderate risky drinking behaviors (Larimer & Cronce, 2002).Skills-based interventions are designed to modify high risk drinking behaviors in two ways: (a) teaching how to cope with life stresses in ways other than alcohol use (e.g., building alternative stress management, relaxation, and social skills), and (b) teaching alcohol-specific harm reduction skills (e.g., drinking in ways to avoid extreme intoxication and negative consequences). These intervention components evolved from self-management approaches for controlled drinking. For example, Miller and Muñoz (2005) developed a manual titled Controlling Your Drinking which outlines self-control strategies in three domains: while you drink, before you drink, and instead of drinking. The 'while you drink' strategies focus on slowing down drinking. The 'before you drink' strategies focus on teaching ways to gain control over drinking by understanding and changing antecedents that lead to heavy drinking. Lastly, the 'instead of drinking' strategies focus on gaining understanding of the reinforcers of alcohol use and teaching alternate ways to achieve these reinforcing effects without alcohol use.Many skills-based interventions designed for college students offer a menu of strategies or tips to students to help them moderate their drinking. However, little is known about the relationship...
