Long-term sustainment of evidence-based treatment (EBT) programs is essential to address behavioral health problems in youth, but the limited and fragmented funding available to behavioral health service agencies makes sustainment difficult. RAND researchers led a team that developed a strategic planning tool, called the Fiscal Mapping Process, to help youth behavioral health service agencies identify funding needs and objectives for an EBT program and develop, implement, and sustain a plan for obtaining that funding. The Fiscal Mapping Process focuses on developing two key capacities for sustaining EBT programs: funding stability and strategic planning. The tool can be used with any youth behavioral health EBT program, but it contains resources for two treatment models used in pilot testing: parent-child interaction therapy for disruptive behavior problems in youth ages 2–7 and trauma-focused cognitive behavioral therapy for traumatic stress symptoms in youth ages 3–18. Evaluation is ongoing, but initial findings suggest that the Fiscal Mapping Process improved the strategic planning and funding stability capacities of service agencies that pilot-tested it. In addition to the tool itself, which is in the format of a Microsoft Excel workbook, the researchers created the Quick-Start Guide for the Fiscal Mapping Process, which orients users to the tool's features, provides a glossary of key terms, and answers frequently asked questions about the tool. A description of the tool's development is provided in the companion report, The Fiscal Mapping Process: Development of a Strategic Planning Tool for Sustainable Financing of Evidence-Based Treatment Programs in Youth Behavioral Health Services.
