Recognition of the heterogeneity among substance abusers has led to increased attention to the issue of client-treatment matching. One approach involves identifying different patterns of use within samples of substance abusers. The present preliminary report employed a cluster analysis of various aspects of cocaine use to examine subgroups of cocaine users within a sample of individuals in treatment for substance abuse. Three clusters emerged, differentiated primarily by quantity/frequency of use and route of administration. The resulting subgroups were compared on measures of external validity. Results suggest that subgroups of cocaine use patterns do exist within a sample of substance abusers. In addition, these subgroups differ in age of cocaine use onset and the severity of negative consequences. Future research is needed to establish the clinical utility of these clusters.
认识到药物滥用者之间的异质性，使得人们对服务对象与治疗匹配问题的关注度有所提高。一种方法是在药物滥用者样本中识别不同的使用模式。本初步报告采用对可卡因使用各个方面的聚类分析，来研究在接受药物滥用治疗的个体样本中的可卡因使用者亚组。出现了三个聚类，主要通过使用量/频率和给药途径加以区分。对所得亚组在外部效度指标上进行了比较。结果表明，在药物滥用者样本中确实存在可卡因使用模式亚组。此外，这些亚组在可卡因使用开始年龄和负面后果的严重程度方面存在差异。需要开展进一步研究来确定这些聚类的临床效用。
