The term that describes the consistency of a treatment or intervention is fidelity. Fidelity refers to the degree to which an intervention is implemented as intended, without deviations or modifications that might alter its effectiveness. In research and program evaluation, ensuring high fidelity is crucial because it ensures that the intervention is delivered in a way that is true to its original design. This includes adherence to protocols, proper training of facilitators, and the appropriate timing and dosage of the intervention.

When fidelity is assessed, it helps researchers and evaluators understand whether observed outcomes can be attributed to the intervention itself and whether it functions as intended in practice. High fidelity is important for drawing valid conclusions about the effectiveness of the treatment or intervention, as variations could compromise both the reliability and validity of the results.
