The flexibility and utility of meta-analytic tools are described, although their application in this context is atypical. The analysis includes 4 comparisons from 3 studies (retrieved N\u00a0= 569) for various groups of clients with COD (homeless persons, offenders, and outpatients) in substance abuse treatment, comparing clients assigned either to an MTC or a control condition of standard services. An additional study is included in a series of sensitivity tests. The overall findings increase the research base of support for the MTC program for clients with COD, as results of the meta-analysis indicate significant MTC treatment effects for 5 of the 6 outcome domains across the 4 comparisons. Limitations of the approach are discussed. Independent replications, clinical trials, multiple outcome domains, and additional meta-analyses should be emphasized in future research. Given the need for research-based approaches, program and policy planners should consider the MTC when designing programs for co-occurring disorders.<\/jats:p>","DOI":"10.1080\/08897077.2010.495662","type":"journal-article","created":{"date-parts":[[2010,8,4]],"date-time":"2010-08-04T09:38:59Z","timestamp":1280914739000},"page":"146-161","source":"Crossref","is-referenced-by-count":26,"title":["Modified Therapeutic Community for Co-Occurring Disorders: Single Investigator Meta Analysis"],"prefix":"10.1177","volume":"31","author":[{"given":"Stanley","family":"Sacks","sequence":"first","affiliation":[{"name":"National Development & Research Institutes, Inc.
