Effectiveness of a Brief Intervention based on Motivational Interviewing in Colombian Adolescents

ABSTRACT Prevention science has identified evidence-based strategies for reducing alcohol and other drug use among adolescents, such as Brief Interventions (BI) and Motivational Interviewing (MI). However, there is little evidence about the effectiveness of these practices in Colombia. This study aimed to analyze the effectiveness of the preventive program Brief Intervention based on Motivational Interviewing (BIMI) in reducing alcohol use in adolescents. The program was administered to 3,159 secondary students through a within-subjects design. The results showed that BIMI is a preventive strategy that diminishes the frequency and quantity of alcohol consumption. The study examines how the elapsed time between sessions influences the results. Implications for prevention and evaluation methodologies are discussed.

摘要：预防科学已确立了一系列可有效降低青少年饮酒及其他药物滥用行为的循证策略，例如简短干预（Brief Interventions，BI）与动机访谈（Motivational Interviewing，MI）。然而目前针对此类措施在哥伦比亚的实施效果，相关研究证据仍较为匮乏。本研究旨在分析基于动机访谈的简短干预（Brief Intervention based on Motivational Interviewing，BIMI）预防项目在降低青少年饮酒行为方面的有效性。该项目采用被试内实验设计，对3159名中学生实施了干预。研究结果显示，BIMI作为一种预防策略，可有效降低青少年饮酒的频率与饮酒量。本研究同时探讨了两次干预疗程之间的间隔时长对干预效果的影响，并就预防工作及评估方法学的优化方向展开了讨论。
