What does a treatment fidelity check measure?

A treatment fidelity check is designed to measure the consistency of how an intervention is implemented according to its predefined plan or protocol. This is crucial for ensuring that the treatment being administered is being delivered as intended, which directly impacts its effectiveness and the outcomes for the individuals involved. By evaluating fidelity, practitioners can identify any deviations from the established procedure and make necessary adjustments to ensure that the intervention is being carried out properly.

This consistency is essential for validating the results of the intervention and ensuring that any observed effects can be attributed to the intervention itself, rather than inconsistencies in its application. Thus, fidelity checks serve as a key mechanism for maintaining the integrity of behavioral interventions and ensuring they are delivered reliably across different settings and practitioners.
