This study examines the program- and individual-level factors that impact the success of drug court clients in terms of: (1) graduation; and (2) not being arrested while participating in the court program. The data consist of 848 individuals in nine drug courts. This paper discusses how different individual- and program-level factors impact the success of drug court participants. The findings suggest that individual- and program-level factors are both important in predicting program graduation and arrest during drug court participation, while controlling for participant demographics. Clients’ education, drug/alcohol usage, program staffing, and clinical standards impact program graduation while criminal history, drug/alcohol usage, number of program hours offered, program staffing, and use of rewards and sanctions predict in-program arrest. Models combining both program- and individual-level factors performed better than either alone, leading to recommendations that agencies should emphasize improving program quality while targeting clients’ needs to achieve greater success.

本研究从以下几个方面探讨了影响毒品法庭客户成功的项目和个人层面的因素：（1）毕业；(2) 在参加法庭活动时没有被逮捕。数据包括 9 个毒品法庭的 848 名个人。本文讨论了不同的个人和项目层面的因素如何影响毒品法庭参与者的成功。研究结果表明，个人和项目层面的因素对于预测毒品法庭参与期间的项目毕业和逮捕都很重要，同时控制参与者的人口统计数据。客户的教育程度、药物/酒精使用情况、项目人员配置和临床标准影响项目毕业，而犯罪史、药物/酒精使用、提供的项目小时数、项目人员配置以及奖励和制裁的使用则预测项目内逮捕。结合项目和个人层面因素的模型比单独使用任何一个因素的效果都要好，因此建议各机构应强调提高项目质量，同时瞄准客户的需求以取得更大的成功。
