Abstract

Although our field has made significant progress in the measurement of procedural fidelity in research studies, we argue for a more nuanced and expansive perspective on procedural fidelity. Specifically, we review the status quo of procedural fidelity measurement in intervention research along with specific suggestions for increasing both precision and focused research on the levels of procedural fidelity that are needed to maximize outcomes for individual participants. Second, we offer an expanded example of procedural fidelity by examining the data on the influence of typical peers, particularly on how the data influence a broad range of skills for individuals with severe disabilities. Finally, we examine the need for multiple layers of procedural fidelity assessment if we are to fully understand the vast array of contextual variables that can influence both procedural fidelity and child outcomes, particularly in a progression of research from initial efficacy assessment through scale-up and replication. We utilize the program-wide implementation of the Pyramid Model for illustrative purposes.
