This study examined the effects of specific services provided in therapeuti
c communities (TCs) to treatment outcomes. Findings are compared to prior a
nalyses of treatment outcomes from the District of Columbia Treatment Initi
ative (DCI) that did not utilize the treatment service information. A subsa
mple of DCI clients randomly assigned to two TC programs, who had remained
in inpatient treatment for at least 60 days, were included in the analyses
(n=371). Logistic regression results illustrated that the lever of vocation
al education services received was positively associated with completing tr
eatment, and participation in group services was associated with decreases
in postdischarge arrest. In addition, clients who received a greater number
of all inpatient services were more likely to complete treatment and were
less likely to be arrested after discharge. Findings suggest that TC progra
ms should consider offering more vocational education and group treatment s
ervices to enhance prosocial behavior following treatment discharge. (C) 20
