Objectives: Recidivism reduction is the primary goal of many correctional programs, and “recidivism” is the most prevalent outcome measure in related program evaluation research. Many different operationalizations of recidivism are used without a clear delineation of how these variations may impact conclusions. This study explores how the definitions of recidivism may impact research findings and resultant policy recommendations regarding the efficacy of parole. Methods: Data from prisoners released in 2008 (n = 12,132) to parole or unconditional release are analyzed according to 10 different operationalizations of recidivism. We compare recidivism rates, time to failure, and hazard rates between groups through the presentation of descriptive statistics and the use of multivariate Cox proportional hazards survival models. Results: Our findings indicate that parole supervision could be deemed either effective or ineffective depending on which definition of recidivism is employed. These findings are largely driven by whether technical parole violations are included into more traditional criminal outcome measures, such as rearrests, reconvictions, or reincarcerations for new crimes, and if court processing times are factored into measures of time to failure. Conclusions: Our results raise questions about the consistency of findings within the corrections literature. These conclusions, given the role that technical violations and court processing times can play, suggest a need for increased specificity when using recidivism as an outcome measure.

This present study examines the sexual and general recidivism rates of 547 convicted sex offenders released before and after the enactment of Megan’s Law in New Jersey. Presenting the longest Megan’s Law evaluation, participants were followed for an average of 15 years after release (range = 10-29 years). Bivariate and multivariate logistic regression equations were estimated to identify covariates significantly associated with both sexual and general recidivism. Group-based trajectories of general recidivism within the 10 years post–prison release were also estimated and compared according to pre–Megan’s Law and post–Megan’s Law release status. No differences in recidivism rates were noted between the cohorts, but differences emerged in the offending trajectories of the high-risk group of offenders within 10 years of release. These results highlight the lack of impact that sex offender registration and notification (SORN) laws have on sexual and general reoffending rates postrelease.

Although the Level of Service Inventory-Revised (LSI-R) has been validated across genders and races, few studies have investigated the validity of the instrument for different combinations of races and genders. Using data from a sample of offenders in New Jersey (N = 9,454), we measure the LSI-R's validity in predicting recidivism within 1 year of prison release. Our findings indicate that the LSI-R is a valid predictor of recidivism across different race and gender combinations; however, the instrument performs poorly at distinguishing recidivists from non-recidivists and exhibits the lowest discriminant capacity for Black males. Policy implications are discussed.

The present study explored the effects of solitary confinement on in-prison outcomes among inmates housed in disciplinary segregation in a northeast state ( N = 398). The deterrent effects of segregation and program participation on future in-prison behaviors were examined. Differences among samples of inmates housed in disciplinary segregation before and after the enactment of policy revisions were also assessed. Findings from bivariate and multivariate analyses indicate most inmates did not have a new infraction; however, certain inmates were more likely to receive a future discipline. Furthermore, completing programming while in disciplinary segregation did not have an effect on future infractions or programming participation. The implications of the research findings are discussed.
