Updated Inventory of Evidence-based, Research-based, and Promising Practices: Prevention and Intervention Services for Adult Behavioral Health (Archived)

The 2013 Washington State Legislature directed the Washington State Institute for Public Policy (WSIPP) to create, in consultation with the Department of Social and Health Services (DSHS), University of Washington Evidence-Based Practice Institute (EBPI), University of Washington Alcohol and Drug Abuse Institute (ADAI), and the Washington Institute for Mental Health Research and Training (WIMHRT), an inventory of evidence-based, research-based, and promising practices.

The initial inventory of interventions and policies in adult mental health and chemical dependency services was published in May 2014. To view the May 2014 results, click here. An update to this inventory was published in January 2015.

While we were not directed by the legislature to update this inventory, a WSIPP Board-approved contract with the Division of Behavioral Health and Rehabilitation at the Department of Social and Health Services enabled WSIPP to review fourteen additional programs and update previously reviewed programs.

Evaluation of the 2016 Truancy Prevention and Intervention Act: Initial Report (Archived)

Washington State has compulsory school attendance laws that require school-aged children to attend school and mandate how schools and courts must respond to unexcused absences. These laws establish a series of escalating interventions that can ultimately result in truant students facing legal consequences, including detention.

The 2016 and 2017 Washington State Legislature modified these requirements. Some significant changes included increasing the information provided to parents about truancy, requiring schools to use formal assessments of students and data-informed steps to address truant behavior, mandating the use of community truancy boards (CTBs), and requiring courts to try alternative methods before ordering detention.

The Washington State Legislature directed WSIPP to evaluate the effectiveness of the 2016 act. In this initial report, we outline the evaluation plan and identify potential data gaps. The final report, due January 2021, will describe changes in CTBs, truancy petition characteristics and outcomes, and student academic outcomes using a combination of descriptive and quasi-experimental methods. If possible, the analysis will include a meta-analysis evaluating the effectiveness of truancy and drop-out prevention programs.

Updated Inventory of Evidence-Based, Research-Based, and Promising Practices: For Prevention and Intervention Services for Children and Juveniles in the Child Welfare, Juvenile Justice, and Mental Health Systems (Archived)

The 2012 Legislature passed E2SHB 2536 with the intention that “prevention and intervention services delivered to children and juveniles in the areas of mental health, child welfare, and juvenile justice be primarily evidence-based and research-based, and it is anticipated that such services will be provided in a manner that is culturally competent.”
The bill directed the Washington State Institute for Public Policy (WSIPP) and the University of Washington Evidence-Based Practice Institute (UW) to publish descriptive definitions and prepare an inventory of evidence-based, research-based, and promising practices and services, and to periodically update the inventory as more practices are identified. This eighth update to the September 30, 2012 publication includes recent reviews of children’s mental health interventions on the inventory. The accompanying report describes the inventory update process, as well as the ongoing technical assistance process by UW. Programs that are new to the inventory, or have a revised classification based on current evidence, are identified in the report.

Wildfire Suppression Cost Study (Archived)

The 2012 Washington State Legislature appropriated funding to conduct a detailed analysis of potential mechanisms for reducing the amount of and variation in the state’s fire suppression costs. The desired analysis consists of two parts:

1. An examination of Oregon’s excess forest fire suppression cost insurance program and an analysis of the potential application of this model for Washington, and
2. An examination of Washington’s total and marginal costs related to staffing and overtime to determine whether these total or marginal costs are in excess of market rates.

Based on this direction, the Washington State Institute for Public Policy (Institute) developed a scope of work that incorporated the legislature’s objectives to address two issues: the variability in wildfire suppression budget requirements and fire suppression labor costs. After a competitive selection process, WSIPP contracted with FCS GROUP to conduct the analysis, and the FCS GROUP team worked primarily with the Department of Natural Resources (DNR) to gather data and information. In addition, FCS GROUP held discussions with key external DNR stakeholders such as the Washington Forest Protection Association, Farm Forestry Association and Weyerhaeuser, and conducted a comparative analysis of how similar programs in Oregon, Idaho, Montana, South Dakota, British Columbia, and the United States Forest Service funded and managed their fire suppression expenditures. This report details this analysis and presents findings from FCS.

This is the tenth update to the initial inventory published in 2012.

The accompanying report describes our standard process for evaluating and classifying research evidence, the process for adding new programs to the inventory, and the reasons that program classifications may change in the current iteration of the inventory. Programs that are new to the inventory or re-reviewed with current evidence are identified in the report.

Assessments and Charges in Washington Department of Corrections Facilities: A Review and Analysis

The 2023 Washington State Legislature directed WSIPP to review all assessments and charges imposed on individuals incarcerated in Department of Corrections (DOC) facilities and their family members and the effect of assessments and charges on the financial status of incarcerated individuals. In this report, we quantified the financial costs of items and services incurred by incarcerated individuals during confinement, assessed their financial status, and explored how DOC collected and used the associated commissions and fees.

First, our review shows that while incarcerated individuals initially received certain items free of charge, they were required to purchase replacements for many of these items thereafter. In FY 2024, individuals spent nearly $37 million on additional items and services, with over 93% of the spending concentrated in five major categories: commissary items, phone calls, electronic media services, and food and personal property packages. Additionally, our price comparison analysis indicates that commissary items were priced relatively low.

Second, our analysis reveals that mandatory deductions amounted to roughly 23% of wages and 32% of funds received during FYs 2022-24. Recent policy changes have increased the number of exemptions to those mandatory deductions. Moreover, our assessment shows that the average individual incurred nearly $2,230 annually on additional items and services. Compensation from correctional work assignments could cover nearly 35% of the spending (on average), with the remainder typically paid by family and/or limited debt.

Lastly, our analysis indicates that DOC charged average gross profit margins ranging from 20% to 40% across these five major categories. Additionally, commissions and fees–primarily from phone calls, media services, and incarceration costs–were relatively small (less than 1%) compared to DOC’s budget and were allocated to improvement activities and CI operational expenses.

Washington School for the Deaf: Models of Education and Service Delivery (Archived)

The 2001 Washington State Legislature directed the Institute to examine educational delivery models for the Washington School for the Deaf.  This report covers issues influencing deaf education; characteristics of deaf and hard of hearing students in Washington; current models of providing education and services for deaf and hard of hearing students, including a comparison of models based on learning environment and cost; and possible alternative roles for WSD in education and service delivery. A literature review written by Susan Easterbrooks of Georgia State University is available above as an appendix. A companion study by the Joint Legislative Audit and Review Committee is available at the JLARC website: http://www.leg.wa.gov/JLARC/AuditAndStudyReports/2002/Pages/02-8.aspx.

Return on Investment: Evidence-Based Options to Improve Statewide Outcomes - July 2011 Update - (Archived)

The 2009 Washington Legislature directed the Institute to “calculate the return on investment to taxpayers from evidence-based prevention and intervention programs and policies.” The Legislature instructed the Institute to produce “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.” The Legislature authorized the Institute to receive outside funding for this project; the MacArthur Foundation supported 80 percent of the work and the Legislature funded the other 20 percent. This main report summarizes our findings. Readers can download the two detailed technical appendices for in depth results and statistical methods.

What Are the Differences Between Short-Term and Long-Term Welfare Users? (Archived)

The majority of women who receive AFDC are short-term assistance users and leave AFDC within two years. Long-term users of public assistance, however, present a dilemma to both state and national policymakers in terms of cost and perceived "welfare dependency." The federal Family Support Act and its Job Opportunities and Basic Skills (JOBS) program now directs states to focus upon education, training, job search, and job development activities for potential long-term users of AFDC. Using five years of Family Income Study data, this study compared the characteristics of short-term and long-term users of AFDC in Washington State during the period of 1988-1992.

Early Childhood Education for Low-Income Students: A Review of the Evidence and Benefit-Cost Analysis (Archived)

WSIPP analyzed how various approaches to early childhood education (ECE) for low-income children impact student outcomes and whether benefits exceed costs. We examined three types of programs: state and district pre-kindergarten, the federal Head Start program, and “model” programs.

To investigate, we conducted a systematic review of research by collecting all studies we could find on the topic. We screened for scientific rigor and only analyzed studies with strong research methods. We identified 49 credible evaluations of whether the three types of ECE for low-income children have a cause-and-effect relationship with student outcomes. The studies in our review measured academic as well as social and emotional development outcomes; a few studies also measured longer term outcomes including crime and teen births.
