Individual brief motivational intervention (iBMI) is an efficacious strategy to reduce heavy drinking by students who are mandated to receive an alcohol intervention following an alcohol-related event. However, despite the strong empirical support for iBMI, it is unknown if the results from rigorously controlled research on iBMI translate to real-world settings. Furthermore, many colleges lack the resources to provide iBMI to mandated students. Therefore, group-delivered BMI (gBMI) might be a cost-effective alternative that can be delivered to a large number of individuals. The purpose of this study was to conduct a comparative effectiveness evaluation of iBMI and gBMI as delivered by staff at a university health services center. Participants (N = 278) were college students who were mandated to receive an alcohol intervention following an alcohol-related incident. Participants were randomized to receive an individual (iBMI; n = 133) or a Group BMI (gBMI; n = 145). Results indicated that both iBMI and gBMI participants reduced their peak estimated blood alcohol concentration (BAC) and the number of negative alcohol-related consequences at 1-, 3-, and 6-months postintervention. The iBMI and gBMI conditions were not significantly different at follow-up. These findings provide preliminary support for the use of iBMI and gBMIs for college students in real-world settings.
个体简短动机干预（iBMI）是一种有效的策略，可减少那些在与酒精相关事件后被要求接受酒精干预的学生的重度饮酒行为。然而，尽管iBMI有强有力的实证支持，但iBMI在严格控制的研究中的结果能否转化到现实环境中尚不清楚。此外，许多大学缺乏资源为被要求的学生提供iBMI。因此，团体提供的BMI（gBMI）可能是一种具有成本效益的替代方案，可以提供给大量个体。本研究的目的是对大学健康服务中心工作人员提供的iBMI和gBMI进行比较有效性评估。参与者（N = 278）是在与酒精相关事件后被要求接受酒精干预的大学生。参与者被随机分配接受个体干预（iBMI；n = 133）或团体BMI干预（gBMI；n = 145）。结果表明，iBMI和gBMI参与者在干预后1个月、3个月和6个月时均降低了其估计的血液酒精浓度峰值（BAC）以及与酒精相关的负面后果数量。随访时，iBMI和gBMI情况没有显著差异。这些发现为在现实环境中对大学生使用iBMI和gBMI提供了初步支持。
