Motivational Interventions for Exercise in Hazardous Drinking College Students

描述（由申请人提供）：大学生的酒精问题发生率很高，国家酒精滥用和酒精中毒研究所针对这一年龄组采取了一些旨在减少酒精使用的干预措施（NIAAA， 2002年）。物质使用，包括酗酒，往往以牺牲其他无物质活动为代价。这个第一阶段的治疗发展项目将研究促进一种特定的无物质活动-运动-作为危险饮酒的干预措施。锻炼对身心健康有很多好处，数据表明，经常锻炼的学生不太可能酗酒。70名危险饮酒（审计得分为bbbb80）的久坐大学生将被随机分为两组：(1)两次50分钟的动机增强疗法（MET）侧重于增加间隔一个月的运动，外加8周的运动收缩，或(2)两次50分钟的MET侧重于增加运动，外加8周的应急管理（CM），以坚持特定的运动活动。MET是一种以客户为中心的指导性方法，通过探索和解决矛盾心理来增强改变的内在动机，而CM是一种行为治疗，为个人提供有形的强化，如完成特定目标行为的奖励。所有参与者每周将与治疗师短暂会面一次，回顾前一周的锻炼合同，并完成下一周的锻炼合同。CM干预组的参与者也将获得前一周经过验证的锻炼（例如计步器读数、校园健身房的出勤记录）所获得的奖励。所有参与者将在基线、2个月（治疗后）和6个月（随访）时进行评估，主要结果指标为身体活动和锻炼的客观和主观指标，以及自我报告的酒精使用情况。次要结局包括与健康相关的体能（例如，身体组成、心血管耐力和肌肉力量的测试）。我们假设，与MET干预相比，MET+CM干预将显示出身体活动、锻炼、身体健康水平的提高，以及酒精使用的减少。这项第一阶段治疗发展研究的结果将指导未来运动相关动机干预作为减少大学生危险饮酒方法的研究。

DESCRIPTION (provided by applicant): College students have high rates of alcohol problems, and the National Institute on Alcohol Abuse and Alcoholism has targeted this age group for a number of intervention initiatives designed to reduce alcohol use (NIAAA, 2002). Substance use, including heavy drinking, often occurs at the expense of other, substance-free, activities. This Stage 1 therapy development project will examine the promotion of one specific substance-free activity - exercise - as an intervention for hazardous drinking. Exercise has numerous physical and mental health benefits, and data suggest that students who engage in exercise regularly are less likely to drink heavily. Seventy hazardous drinking (AUDIT scores > 8) college students who are sedentary will be randomized to one of two conditions: (1) two 50-minute sessions of motivational enhancement therapy (MET) focused on increasing exercise spaced one month apart plus 8 weeks of exercise contracting, or (2) two 50-minute sessions of MET focused on increasing exercise plus 8 weeks of contingency management (CM) for adhering to specific exercise activities. MET is a client-centered, directive method of enhancing intrinsic motivation to change by exploring and resolving ambivalence, and CM is a behavioral treatment that offers individuals tangible reinforcement such as prizes for completion of specific target behaviors. All participants will meet briefly with a therapist once per week to review the prior week's exercise contract and complete an exercise contract for the upcoming week. Those in the CM intervention will also receive any reinforcement earned for verified exercise (e.g., pedometer readings, attendance records from campus gym) in the prior week. Assessments of all participants will take place at baseline, 2-months (post-treatment), and 6-months (follow-up) with primary outcome measures being objective and subjective indices of physical activity and exercise, and self-reported alcohol use. Secondary outcomes include health-related physical fitness (e.g., tests of body composition, cardiovascular endurance, and muscle strength). We hypothesize that the MET+CM intervention will show increased levels of physical activity, exercise, physical fitness, and reductions in alcohol use in comparison to the MET intervention. Results from this Stage 1 therapy development study will guide future investigations of exercise-related motivational interventions as a method for reducing hazardous drinking in college students. PUBLIC HEALTH RELEVANCE: The National Institute of Alcohol Abuse and Alcoholism has identified hazardous drinking in college students as a significant concern and a research priority due to its significant prevalence on many college campuses and its association with many adverse consequences. Research suggests that engaging college students in activities unrelated to drinking decreases alcohol use. This pilot study will seek to decrease alcohol use by engaging sedentary hazardous drinking college students in an exercise program. Exercise has numerous mental and physical health benefits. Exercise is hypothesized to reduce hazardous drinking due to its function as a coping mechanism.
