The current study provides empirical data associated with successful program completion by examining the differing characteristics between clients who graduated from a community-based reintegration program operating in Chattanooga, Tennessee, and those who left prior to graduation. Substance dependence risk, level of education, employment or in-school status prior to last arrest, and parole/probation risk classification prior to program entry were compared for program graduates and defectors. Information was gathered from client case files and police and Tennessee Department of Correction records. Results indicate that the program graduates had lower substance dependence and parole/probation risk classification as well as a higher level of education. Implications are discussed regarding the necessity to increase participation of high-risk individuals. (Contains 3 tables.)
