Evidence-based and research-based programs to be used by adult corrections in Washington State are inventoried. Three parts comprise this report: definitions—evidence-based, research-based, and cost-beneficial; updated reviews using a three-step research process (evidence, benefits and costs, and risk), effective practices in community corrections, sex offender treatment, and conclusion; and the inventory. “WSIPP identified two programs—sex offender treatment and EPICS—that were not previously included in WSIPP’s evidence- and research-based results. Our updated findings on the two topics in this report allowed us to incorporate the results in the adult corrections inventory. The weight of the evidence indicates that sex offender treatment, delivered in confinement or in the community, is evidence-based and generates benefits that exceed costs. Our findings on EPICS [Effective Practices in Community Supervision], however, are not as clear cut. While we find supervision based on RNR principles is effective, the evidence on the particular approach—EPICS—is still undetermined until further research becomes available” (p. 5-6).
An overview is presented of findings (as of July 2011) regarding “a comprehensive list of programs and policies that improve … outcomes for children and adults in Washington and result in more cost-efficient use of public resources” (p. 1). Sections comprising this report are: summary; background; the four-step research approach that assesses what works, calculates costs and benefits and ranks options, measures the risks associated with the analysis, and estimates the impact of various option combinations on statewide outcomes. Also included are two Technical Appendixes that provide in-depth results.
If your agency is thinking of using the Duluth model you need to read this report. It explains why the Duluth model for domestic violence (DV) treatment does not reduce DV recidivism. Group treatment of DV offenders with the Duluth model and four other models (cognitive behavioral therapy (CBT), relationship enhancement, substance abuse treatment, and group couples counseling) were evaluated. “Based on six rigorous outcome evaluations of group-based DV treatment for male offenders, we conclude that the Duluth model, the most common treatment approach, appears to have no effect on recidivism … There may be other group-based treatments for male DV offenders that effectively reduce DV recidivism … Unfortunately, these interventions are so varied in their approaches that we cannot identify a particular group-based treatment approach to replace the Duluth-like model required by Washington State law” (p. 12).
