The CSAT Methamphetamine Treatment Project (MTP) is a multisite study with a two-fold purpose: to assess the feasibility and outcomes generated by a technology transfer of the Matrix treatment model for methamphetamine (MA) abuse into several community-based treatment programs, and specifically to compare outcomes of treatment as usual at each site with outcomes of the Matrix model, as implemented in each site. The study comprises seven sites, geographically situated in Hawaii, Northern and Southern California, and Montana. This article presents a demographic description of the cohort, and describes patterns of drug use, abuse, and related problems among the 169 participants recruited in the first six months of the study, from April through September 1999. Specific analyses presented include: demographic composition of the sample with respect to gender, age, ethnicity, education completed, employment status, and income; primary drug used, and mean percent of days using various drugs including MA, alcohol, and marijuana; and percent of sample reporting various routes of drug administration. Mean baseline Addiction Severity Index composite scores are presented that describe medical, employment, alcohol, drug, legal, family/social, and psychiatric status for the sample. Also presented here are comparisons of this preliminary population to other populations reported in the literature. This early subset of MTP participants is similar to other methamphetamine-abusing populations described in the literature in age, years of education, income, and mean years of use. However, because of its multisite structure and the locations of its constituent sites, the MTP population has greater variation in ethnic makeup than do populations from other studies, offering an opportunity to provide useful new information about drug use patterns and treatment responses in populations not previously studied.
社区服务管理局甲基苯丙胺治疗项目（MTP）是一项多地点研究，具有双重目的：评估将用于治疗甲基苯丙胺（MA）滥用的矩阵治疗模式技术转移到多个社区治疗项目中的可行性和效果，特别是比较每个地点常规治疗的效果与在各地点实施的矩阵模式的效果。该研究包括七个地点，分布在夏威夷、加利福尼亚州北部和南部以及蒙大拿州。本文介绍了该队列的人口统计学描述，并描述了在1999年4月至9月研究的前六个月招募的169名参与者中的药物使用、滥用及相关问题模式。所呈现的具体分析包括：样本在性别、年龄、种族、完成的教育程度、就业状况和收入方面的人口构成；主要使用的药物，以及使用包括甲基苯丙胺、酒精和大麻在内的各种药物的平均天数百分比；以及报告各种给药途径的样本百分比。给出了平均基线成瘾严重程度指数综合得分，描述了样本的医疗、就业、酒精、药物、法律、家庭/社会和精神状态。还给出了该初步人群与文献中报道的其他人群的比较。MTP参与者的这个早期子集在年龄、受教育年限、收入和平均使用年限方面与文献中描述的其他甲基苯丙胺滥用人群相似。然而，由于其多地点结构及其组成地点的位置，MTP人群在种族构成上比其他研究中的人群有更大的差异，这为提供关于以前未研究人群的药物使用模式和治疗反应的有用新信息提供了机会。
