Demonstrations of the effectiveness of interventions requires evidence that the model can be implemented with fidelity. Caregiving interventions that are tailored to the individual or family require flexibility, which adds some challenges to the assessment of fidelity. This paper outlines the components necessary for examining treatment fidelity and common barriers to implementing fidelity studies, offers considerations for designing fidelity studies with tailored caregiver interventions, and aims to provide a set of procedures that can be used to guide future fidelity studies.
