Journal Article 1: Ostermann, M. (2015). How do former inmates perform in the community? A survival analysis of rearrests, reconvictions, and technical parole violations. Crime & Delinquency, 61(2), 163–187.
Abstract: This study provides insight into the postrelease performance of all former inmates with available data who were released from a prison in New Jersey in 2006 (N = 12,187). Three indicators of recidivism are considered: (a) an arrest for a new crime, (b) a conviction for a new crime, and (c) a technical parole violation. Individuals are categorized into groups according to the release mechanism that they experienced: discretionary parole, mandatory parole, or unconditional release. Multivariate analyses utilize Cox proportional hazards survival tests. Results indicate that after approximately 3 years of follow-up time, those released to supervision were generally less involved in new crimes when compared with those who were released unconditionally. However, a high proportion of those who were paroled recidivated shortly after release, and the predicted probability that a former inmate would recidivate did not substantially differ between release groups in the presence of statistical controls.
Journal Article 2: Ostermann, M., Salerno, L. M., & Hyatt, J. M. (2015). How different operationalizations of recidivism impact conclusions of effectiveness of parole supervision. Journal of Research in Crime and Delinquency, 52(6), 771–796.
Abstract: 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.
