Abstract

Brief motivational intervention (BMI) and personalized feedback intervention (PFI) are individual-focused brief alcohol intervention approaches that have been proven efficacious for reducing alcohol use among college students and young adults. Although the efficacy of these two intervention approaches has been well established, little is known about the factors that may modify their effects on alcohol outcomes. In particular, high school drinking may be a risk factor for continued and heightened use of alcohol in college, and thus may influence the outcomes of BMI and PFI. The purpose of this study was to investigate whether high school drinking was associated with different intervention outcomes among students who received PFI compared to those who received BMI. We conducted moderation analyses examining 348 mandated students (60.1% male; 73.3% White; and 61.5% first-year student) who were randomly assigned to either a BMI or a PFI and whose alcohol consumption was assessed at 4-month and 15-month follow-ups. Results from marginalized zero-inflated Poisson models showed that high school drinking moderated the effects of PFI and BMI at the 4-month follow-up but not at the 15-month follow-up. Specifically, students who reported no drinking in their senior year of high school consumed a 49% higher mean number of drinks after receiving BMI than PFI at the 4-month follow-up. The results suggest that alcohol consumption in high school may be informative when screening and allocating students to appropriate alcohol interventions to meet their different needs.

摘要

简短动机干预（Brief Motivational Intervention, BMI）与个性化反馈干预（Personalized Feedback Intervention, PFI）是聚焦个体的简短酒精干预手段，已被证实可有效降低大学生及青年群体的酒精摄入水平。尽管这两类干预手段的有效性已得到充分验证，但目前学界对可能调节其酒精相关干预结局的影响因素仍知之甚少。具体而言，高中饮酒行为可能是大学阶段持续饮酒且饮酒量升高的风险因素，进而可能影响BMI与PFI的干预效果。本研究旨在探究，相较于接受BMI的学生，高中饮酒行为是否会导致接受PFI的学生呈现出不同的干预结局。我们针对348名受强制参与研究的学生（其中60.1%为男性，73.3%为白人，61.5%为一年级本科生）开展调节效应分析，这些学生被随机分配至BMI组或PFI组，并在干预后4个月及15个月完成酒精摄入情况的随访评估。边际化零膨胀泊松模型（marginalized zero-inflated Poisson models）的分析结果显示，在干预后4个月随访时，高中饮酒行为对PFI与BMI的干预效果存在显著调节效应，但在15个月随访时未观察到该效应。具体而言，在高中高年级未饮酒的学生中，干预后4个月随访时，接受BMI的学生平均饮酒量较接受PFI的学生高出49%。本研究结果表明，在针对学生开展酒精干预的筛查与方案分配工作中，可参考其高中阶段的饮酒行为，以匹配其个性化需求，优化干预策略。
