Logic Models and the SPF
SAMHSA's Strategic Prevention Framework (SPF) is a five-step planning process designed to help states, tribes, jurisdictions, and communities select, implement, and evaluate evidence-based, culturally appropriate, sustainable prevention activities. The SPF is a complex process that drives planners towards defining specific results they expect to accomplish with their overall prevention plan. Communities implementing the SPF are expected to use an outcomes-based logic model to guide their prevention efforts.
Outcomes-based logic models describe the relationship among multiple factors and components in a defined community, and how they may be used to produce one or more desired outcomes. They provide logical connections between (1) the problems identified by communities, (2) the specific factors in a community that are influencing or contributing to the problems, (3) the interventions planners will use to address the risk and protective factors related to the problems, and (4) the anticipated changes expected to occur.
