The objectives of Ohio's shock probation, which involves split sentences, includes impressing offenders with the hardship and psychological consequences of prison life and making offenders aware of the seriousness of their crimes without resorting to lengthy and potentially damaging imprisonment. The program's major premise is that the 'shock' of incarceration will cause the offender to avoid future involvement with crime. Proponents of shock probation generally agree that the period of incarceration should be brief and its use should be limited to youthful first offenders. However, positive findings in a study of 556 shock probationers with prior records indicate that the shock experience should not be limited to first-time offenders. In addition, the length of incarceration -- presently between 90 and 130 days -- can be shortened without affecting reincarceration rates. Reincarceration rates for shock probation have never exceeded 26 percent, and according to official records from the Ohio Department of Rehabilitation and Corrections, only 10.4 percent of the offenders released on shock probation over the 15-year life of the program have been reincarcerated. Shock probation can reduce institutional overcrowding, and it is consistent with the objectives of reintegration and public safety. Two tables and 31 references are included.
