This report estimates whether the Sex Offender Treatment Program (SOTP) reduces recidivism by comparing the recidivism rates of sex offenders who were willing but did not participate in SOTP with those who did participate in the program.

The Chemical Dependency Disposition Alternative (CDDA) was created by the 1997 Washington State Legislature as a sentencing option for juvenile offenders. The goal was to reduce recidivism by providing treatment for chemically dependent or substance abusing youth. This report assesses the feasibility of conducting a retrospective outcome evaluation to compare the recidivism rates of a CDDA group to similar youth who did not receive CDDA. We investigated two potential comparison groups: substance abusing youth adjudicated before CDDA started, and substance abusing youth receiving no treatment after CDDA started. The Institute found that an appropriate comparison group could not be identified. Thus, it was not possible to evaluate the impact of CDDA on recidivism.

The Chemical Dependency Disposition Alternative (CDDA) was created by the 1997 Washington State Legislature as a sentencing option for juvenile offenders. The goal was to reduce recidivism by providing treatment for chemically dependent or substance abusing youth. The Institute was directed by the 1997 Legislature to evaluate CDDA to determine its impacts on recidivism. The Institute surveyed the courts to determine how to identify both the CDDA and the CDDA comparison groups. After the initial phase of data collection, the Institute found that an appropriate comparison group could not be identified. Thus, it was not possible to evaluate the impact of CDDA on recidivism or conduct a cost-benefit analysis. However, the survey revealed variations in the implementation of CDDA across the state.

The Washington State Institute for Public Policy was directed by the 2005 Washington Legislature to estimate whether “evidence-based” treatment for people with alcohol, drug, and mental health disorders offers economic advantages. Do benefits outweigh costs? And, if so, what is the magnitude of the potential fiscal savings to government, as well as the total net benefits to all of Washington?

To answer these questions, we systematically reviewed the “what works” literature regarding treatments for people with alcohol, drug, and mental health disorders. We then estimated the monetary value of the benefits, including factors such as improved performance in the job market, reduced health care and other costs, and reduced crime-related costs.

Washington’s Sexually Violent Predator (SVP) statute permits the civil commitment of adult and juvenile sex offenders found to be a high risk to the public. Since the law’s enactment in 1990, to the end of 2003, 31 juvenile sex offenders were identified as possibly meeting the statutory criteria for civil commitment. These individuals represent approximately 1 percent of the total juvenile sex offenders paroled in this 13-year period.

The attorney general or prosecuting attorney declined to file on two-thirds (21) of these referrals; the individuals were released to the community. Follow-up data were available for all 21 juveniles through December 31, 2005.

In 1990, Washington became the first state to authorize the release of information regarding sex offenders to the public. Since then, the law has been amended numerous times to expand its application, increase uniformity across counties, and increase citizen access.

The 2001 Washington State Legislature directed the Institute to conduct a longitudinal study on the outcomes of state-funded mental health clients to identify best practices in the provision of public mental health services. This report contains the two-year follow-up of public mental health clients selected from the baseline year of 2002. Two sets of analyses are performed. The first examines differences in client profiles between all baseline clients and those who continued to receive public mental health services in 2004. The second examines outcomes in 2004 of all adult clients from the baseline and client characteristics associated with variation in outcomes. Outcomes examined include utilization of public mental health services, utilization of other public medical services, employment, and criminal justice involvement.

This study reviews all rigorous evaluations of Intensive Family Preservation Services (IFPS) programs. We sorted these evaluations based on fidelity to the Homebuilders® model. Findings: IFPS programs that adhere closely to the Homebuilders® model significantly reduce out-of-home placements and subsequent abuse and neglect. We estimate that such programs produce $2.54 of benefits for each dollar of cost. Non-Homebuilders® programs produce no significant effect on either outcome.
