Using the 1992-1995 National Treatment Improvement Evaluation Study data, we employ principal components analysis to create treatment service factors based on both patient self-reports and treatment record extracts. We included these factors in multivariate models for 1,136 outpatient drug-free treatment patients to estimate the relationship between services and post-treatment employment and crime. Although our models indicated some significant predictors of employment and crime, the overall effects of services were generally insignificant. We conclude that either services are unrelated to outcomes or if they are related then we are not measuring the key aspects of service provision that may be important. The study's limitations are noted.
利用1992 - 1995年全国治疗改善评估研究数据，我们采用主成分分析法，基于患者自我报告和治疗记录摘要创建治疗服务因素。我们将这些因素纳入针对1136名门诊戒毒治疗患者的多变量模型中，以估计服务与治疗后就业及犯罪之间的关系。尽管我们的模型显示了一些就业和犯罪的显著预测因素，但服务的总体影响通常不显著。我们得出结论，要么服务与结果无关，要么即便有关，我们也未衡量出可能重要的服务提供关键方面。文中指出了该研究的局限性。
