The Effects of In-Prison Substance Abuse Treatment on Post-Release Drug Use and Criminality: Massachusetts' Cognitive/Behavioral Treatment Program

Douglas McDonald, Abt Associates Inc.

ABSTRACT
This paper would present the findings of a six year study to follow released prisoners and to estimate the impact of an in-prison drug treatment program on (a post-release criminality and (b) post-release drug use. The program has been operating in most Massachusetts prisons for several years and is among the most ambitious in the country. Although the initial design was experimental, objections to random assignment scuttled it, and we used a quasi-experimental analytic method instead.
