行为经济学理论表明，增加参与建设性的，无物质的活动，为长期目标服务（例如，大学毕业，职业发展，健康）可以减少酒精使用和相关问题。然而，在高风险的大学环境中从事这样的活动需要自我调节的能力，避免奖励但危险的行为（如饮酒），同时也有效地组织行为，以追求延迟的学术和职业相关的奖励。目前的二级数据分析评估了自我调节作为酒精干预试验中行为改变的潜在机制，该试验将标准的酒精关注的简短动机干预（BMI）加上行为经济学无物质活动会话（SFAS）与酒精BMI加上放松训练（反应时间[RT]）会话进行了比较（Murphy et al.，2012年）。参与者是82名一年级本科生（50%女性; M年龄= 18.5，SD=。71)报告上个月有2次或2次以上重度饮酒事件的患者。在完成基线评估和个人酒精重点BMI后，参与者被随机分配到SFAS或RT阶段。与BMI+ RT相比，BMI+ SFAS条件在1个月时报告了更大的平均自我调节。此外，1个月时的自我调节显著介导了6个月随访时条件与酒精相关结局之间的关系。虽然是初步的，这些结果表明，简短的行为经济干预元素，试图增加未来的目标追求和无物质的活动，可以提高标准酒精BMI的短期疗效，这种效果可能是由于部分增加自我调节。
Behavioral economic theory suggests that increased engagement in constructive, substance-free activities that are in the service of long-term goals (eg, college graduation, career development, health) can decrease alcohol use and related problems. However, engaging in activities such as these in the high-risk college environment requires the ability to self-regulate by avoiding rewarding but risky behaviors (eg, drinking) while also effectively organizing behavior in the pursuit of delayed academic and career-related rewards. The current secondary data analyses evaluated self-regulation as a potential mechanism of behavior change in an alcohol intervention trial that compared a standard alcohol-focused brief motivational intervention (BMI) plus a behavioral economic substance-free activity session (SFAS) with an alcohol BMI plus relaxation training (reaction time [RT]) session (Murphy et al., 2012). Participants were 82 first-year undergraduate students (50% women; M age= 18.5, SD=. 71) who reported 2 or more past-month heavy drinking episodes. After completing a baseline assessment and an individual alcohol-focused BMI, participants were randomized to either the SFAS or the RT session. The BMI+ SFAS condition reported greater mean self-regulation at 1 month compared with BMI+ RT. Furthermore, self-regulation at 1 month significantly mediated the relation between condition and alcohol-related outcomes at 6-month follow-up. Although preliminary, these results suggest that brief behavioral economic intervention elements that an attempt to increase future goal pursuit and substance-free activities can enhance the short-term efficacy of standard alcohol BMIs and that this effect may be due in part to increases in self-regulation.
