Knowledge of essential intervention components is supported by evidence,
theory, and developer insight and is reflected in intervention manual,
materials, and fidelity measures. The CORE model makes this
“latent” knowledge observable and concrete by documenting both
essential intervention components and their rationales for effectiveness. The
CORE Fidelity Method therefore supports informed revisions to original
intervention documents; new documents; better measurement of fidelity,
mechanisms of efficacy, and intervention outcomes; and informs adaptations when
implementing in new settings.
