programfidelity
Program fidelity refers to the extent to which a program is delivered as it was originally designed and intended. It is a crucial concept in program evaluation, implementation science, and the replication of evidence-based practices. High program fidelity means that the program's core components, activities, and theoretical underpinnings are consistently and accurately implemented across different settings and by different providers. Conversely, low fidelity occurs when the program deviates significantly from its original model, potentially altering its intended outcomes.
Several factors influence program fidelity. These can include the training and support provided to implementers, the
Measuring program fidelity typically involves direct observation, self-report surveys, review of program records, or interviews with
