Hispanic individuals are underrepresented in clinical and research populations and are often excluded from clinical trials in the United States. Hence, there are few data on the effectiveness of most empirically validated therapies for Hispanic substance users. The authors conducted a multisite randomized trial comparing the effectiveness of 3 individual sessions of motivational enhancement therapy with that of 3 individual sessions of counseling as usual on treatment retention and frequency of substance use; all assessment and treatment sessions were conducted in Spanish among 405 individuals seeking treatment for any type of current substance use. Treatment exposure was good, with 66% of participants completing all 3 protocol sessions. Although both interventions resulted in reductions in substance use during the 4-week therapy phase, there were no significant Treatment Condition x Time interactions nor Site x Treatment Condition interactions. Results suggest that the individual treatments delivered in Spanish were both attractive to and effective with this heterogeneous group of Hispanic adults, but the differential effectiveness of motivational enhancement therapy may be limited to those whose primary substance use problem is alcohol and may be fairly modest in magnitude.
西班牙裔个体在临床和研究人群中的占比不足，在美国往往被排除在临床试验之外。因此，关于大多数经实证验证的疗法对西班牙裔药物使用者有效性的数据很少。作者进行了一项多中心随机试验，比较了3次个体动机增强疗法与3次常规咨询个体疗法在治疗保留率和药物使用频率方面的有效性；所有评估和治疗环节均用西班牙语对405名寻求治疗当前任何类型药物使用问题的个体进行。治疗依从性良好，66%的参与者完成了全部3次方案疗程。尽管两种干预措施在4周治疗阶段均导致药物使用减少，但不存在显著的治疗条件×时间交互作用或地点×治疗条件交互作用。结果表明，用西班牙语提供的个体治疗对这群异质性的西班牙裔成年人既有吸引力又有效，但动机增强疗法的差异有效性可能仅限于那些主要药物使用问题是酒精的人，且效果幅度可能相当有限。
