James Hess and Susan Turner, University of California, Irvine

Building upon the 2021 report titled The Effect of Prison Industry on Recidivism: An Evaluation of California Prison Industry Authority (CALPIA), this study further analyzes the sample of individuals who participated in CALPIA programs by separating the CALPIA programs into thirteen different groups, placing similar programs together. Thus, this 2023 report is a comparison within CALPIA programs only. 

This UCI study has also been incorporated into a report published by CALPIA.

The University of California, Irvine collaborated with California Correctional Health Care Services to compile a report that examines the delivery of Medication Assisted Treatment (MAT) to incarcerated persons in jails and prisons within the United States. The expansion of MAT in corrections is gaining national attention due to the dramatic increase in opioid overdoses and overdose deaths from synthetic opioids. Besides California, based on a review of publicly available information, only 14 states offer comprehensive MAT services at either intake and/or release in a considerable number of its jails and prisons. Overall, there is significant variability among states regarding the delivery of MAT to incarcerated persons. The goal of this report is to document evidence-based practices gathered from California and other correctional systems that can be used to guide expansion of MAT to justice-involved populations.
