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.

尽管我们的领域在研究中在程序保真度的测量方面取得了重大进展，但我们主张对程序保真度有更细致和更广泛的看法。具体来说，我们回顾了干预研究中程序保真度测量的现状，并提出了具体建议，以提高对程序保真度水平的精确度和重点研究，以最大限度地提高个体参与者的结果。其次，我们通过检查有关典型同龄人影响的数据，特别是数据如何影响严重残疾者的广泛技能，提供了程序保真度的扩展示例。最后，如果我们要充分了解可能影响程序保真度和儿童结果的大量背景变量，特别是在从初始功效评估到扩大和复制的研究进展中，我们将检查对多层程序保真度评估的需求。我们利用金字塔模型的程序范围实施来进行说明。
