BACKGROUND/OBJECTIVES: Motivational Enhancement Treatment in Spanish (METS) is a brief intervention aimed at resolving patient ambivalence towards behavior change that has demonstrated efficacy in substance use disorder treatment to reduce use and increase treatment engagement in different populations. In order to have evidence for its implementation in Mexico, a multi-site, randomized, two-arm, controlled clinical trial was conducted at three outpatient addiction treatment centers in the country to compare the effect of METS with Counseling as Usual (CAU).
One hundred and twenty patients were randomized to receive three sessions of METS ( = 54) or CAU ( = 66) during the first four weeks of treatment and were assessed during the following 12 weeks. Primary outcome measures were self-reported days of substance use and of treatment services utilization, which were tested using Generalized Estimating Equations.
Results associated both conditions with significant changes in substance use over, whereas there were no differences between conditions in substance use or in service utilization.
Findings do not support the hypothesis that METS is more effective than CAU, but suggest that brief interventions at treatment initiation may improve patient outcomes.
背景/目的：西班牙语动机增强疗法（METS）是一种简短干预措施，旨在解决患者对行为改变的矛盾心理，该疗法已在物质使用障碍治疗中证明有效，可减少不同人群的物质使用并提高治疗参与度。为了获得在墨西哥实施该疗法的证据，在该国三个门诊成瘾治疗中心进行了一项多中心、随机、双臂对照临床试验，以比较METS与常规咨询（CAU）的效果。
120名患者在治疗的前四周被随机分为接受三次METS治疗（n = 54）或CAU治疗（n = 66），并在接下来的12周内进行评估。主要结局指标是自我报告的物质使用天数和治疗服务利用天数，使用广义估计方程进行检验。
两种治疗条件均与物质使用的显著变化相关，但在物质使用或服务利用方面，两种条件之间没有差异。
研究结果不支持METS比CAU更有效的假设，但表明治疗开始时的简短干预可能会改善患者的治疗效果。
