Evidence-Based Practice Definitions and Glossaries
The terms "evidence-based" and "evidence-informed" are defined differently in different contexts.
Evidence-based practices are approaches to prevention or treatment that are validated by some form of documented scientific evidence. This includes findings established through controlled clinical studies, but other methods of establishing evidence are valid as well.
Evidence-based programs use a defined curriculum or set of services that, when implemented with fidelity as a whole, has been validated by some form of scientific evidence. Evidence-based practices and programs may be described as "supported" or "well-supported", depending on the strength of the research design.
Evidence-informed practices use the best available research and practice knowledge to guide program design and implementation. This informed practice allows for innovation while incorporating the lessons learned from the existing research literature. Ideally, evidence-based and evidence-informed programs and practices should be responsive to families' cultural backgrounds, community values, and individual preferences.
