Effects of Prison Versus Probation in California, 1980-1982

Published by National Institute of Justice | Department of Justice | Metadata Last Checked: November 14, 2025 | Last Modified: 2006-01-18T00:00:00
This study was divided into two phases. The first assessed the effects of different sanctions on separate criminal populations, focusing on probation as a sentencing alternative for felons. The second phase used a quasi-experimental design to address how imprisonment affects criminal behavior when criminals are released. Specific issues included: (a) the effect that imprisonment (vs. probation) and length of time served have on recidivism, (b) the amount of crime prevented by imprisoning offenders rather than placing them on probation, and (c) costs to the system for achieving that reduction in crime.
