For all releasees, prior criminal history was the most important factor for distinguishing recidivists from nonrecidivists, with recidivism defined as either arrest or incarceration after release. Parolees with several prior arrests or incarcerations were more likely than those with less extensive criminal histories to be arrested or imprisoned over the study period. Those successfully completing parole were less likely than other releasees to be arrested during the followup period. Thirty-eight percent of the 230 parolees were arrested at least once during the followup period, with 44 percent of the arrests being for property crimes and 23 percent for violent offenses. Less than 10 percent of the parolees were incarcerated. Parolees tended to have fewer prior arrests than the other types of releasees. Parolees were least likely of all types of releasees to recidivate, and offenders under conditional release were the most likely to recidivate. Parolees also recidivated at a slower rate. 8 figures, 13 tables, 12 notes, and 6-item bibliography.
