减少犯罪提供了与药物滥用治疗（SAT）相关的关键好处。持械抢劫是一些涉毒罪犯犯下的代价特别高昂和频繁的罪行。许多研究采用的评估方法低估了抢劫的真实成本，从而低估了与sat相关的抢劫减少的真正社会效益。同时，回归均值和自我报告偏差可能导致前后比较夸大与SAT相关的犯罪减少。使用1992-1997年国家治疗改善评估研究（NTIES）的数据，我们检查了五种住院和门诊SAT模式下客户自我报告抢劫的前后差异。采用固定效应负二项回归检验持械抢劫的发生率降低率。为了避免抢劫而愿意付钱的公开数据被用来确定这些影响的社会价值。研究了不同SAT模式下IRR的差异，以限制潜在的偏差。所有的SAT模式都与抢劫的大量和统计上显著的减少有关。自我报告的抢劫平均数量从进入前的0.83/客户/年下降到SAT后的0.12/客户/年（p < 0.001）。在最坏的情况下，与门诊美沙酮和住宅SAT相关的武装抢劫减少的货币化估值超过了这些干预措施的经济成本。传统智慧假设SAT的经济效益。我们发现SAT比通常认为的更有益。版权所有(C) 2007约翰威利父子有限公司
Reduced crime provides a key benefit associated with substance abuse treatment (SAT). Armed robbery is an especially costly and frequent crime committed by some drug-involved offenders. Many studies employ valuation methods that understate the true costs of robbery, and thus the true social benefits of SAT-related robbery reduction. At the same time, regression to the mean and self-report bias may lead pre-post comparisons to overstate crime reductions associated with SAT.Using 1992-1997 data from the National Treatment Improvement Evaluation Study (NTIES), we examined pre-post differences in self-reported robbery among clients in five residential and outpatient SAT modalities. Fixed-effect negative binomial regression was used to examine incidence rate reductions (IRR) in armed robbery. Published data on willingness to pay to avoid robbery were used to determine the social valuation of these effects. Differences in IRR across SAT modalities were explored to bound potential biases. All SAT modalities were associated with large and statistically significant reductions in robbery. The average number of self-reported robberies declined from 0.83/client/year pre-entry to 0.12/client/year following SAT (p < 0.001). Under worst-case assumptions, monetized valuations of reductions in armed robbery associated with outpatient methadone and residential SAT exceeded economic costs of these interventions. Conventional wisdom posits the economic benefits of SAT. We find that SAT is even more beneficial than is commonly assumed. Copyright (C) 2007 John Wiley & Sons, Ltd.
