What is Fidelity?

Fidelity in the context of intervention refers to the measure in which an intervention is implemented and delivered as intended without significant deviation or modification. Fidelity is an essential consideration in implementing evidence-based practices and interventions, as deviations from the intended design can impact the effectiveness and outcomes of the intervention.

Fidelity is typically evaluated by comparing the actual implementation of an intervention to its original design or protocol and can be monitored through various means such as observation, self-report, or standardized measures. Maintaining high levels of fidelity is essential for ensuring the validity of research findings and that interventions are delivered consistently and effectively.
