It focuses on the importance of identifying, operationalizing, and implementing the “core components” of evidence-based and evidence-informed interventions that likely are critical to producing positive outcomes. The brief offers a definition of “core components,” discusses challenges and processes related to identifying and validating them, highlights rationales for the importance of operationalizing core components, and explores implications for selecting, funding, implementing, scaling up, and evaluating programs.en-USinterventionpracticeoperationalizeprogramArticle
