This article reports on results from a recently completed randomized field experiment that tested the effects of intensive supervision probation/parole (ISP) for drug-involved offenders.
The ISP demonstration project included five jurisdictions: Contra Costa, Calif.; Seattle, Wash; Des Moines, Iowa; Santa Fe, N. Mex.; and Winchester, Va. Jurisdictions developed ISP programs tailored to their own contexts, using the general ISP model developed by Georgia and New Jersey in the early 1980's Results show that ISP offenders were seen more often, submitted more often to drug testing, received more drug counseling, and had higher levels of employment than their counterparts on routine probation/parole supervision. Regarding 1-year recidivism outcomes, a higher proportion of ISP offenders had technical violations (primarily for drug use), but there was no difference between the two study groups in new criminal arrests. At the end of the 1-year followup, more ISP offenders had been placed in jail or prison (mostly for technical violations). This policy drove up system costs, which for ISP averaged just under $8,000 per year per offender compared to approximately $5,500 per year per offender for routine supervision. This article concludes with a discussion of how these results can be used to inform future ISP research and policy discussions. 1 table, 5 figures, 10 notes, and 26 references
