Strengthening the procedural fidelity research‐to‐practice loop in animal behavior
The way you calculate procedural fidelity can flip your conclusion—choose and lock your metric before you gather data.
01Research in Context
What this study did
Kodak et al. (2022) looked at every paper that measured procedural fidelity in animal labs. They asked: how do researchers pick fidelity metrics and crunch the numbers?
The team wrote a story-style review. They compared how animal and human studies track whether staff run procedures the same way each time.
What they found
The same data can say "high fidelity" or "low fidelity" just by changing the math. Picking the metric after you see the graph can hide mistakes.
Animal labs share the same trap. The paper shows a loop: better metrics → clearer data → better practice → back to better metrics.
How this fits with other research
Manolov et al. (2022) also warn about post-hoc picks. They give a flowchart to choose effect measures before data collection. Kodak adds: do the same for fidelity metrics.
Ninci (2023) tells analysts to guard internal validity when they eye-ball graphs. Kodak widens the lens to the staff side—did the tech even do the protocol right?
Young (2019) offers a Monte Carlo app for p-values. Kodak nods: any stat tool is only as good as the fidelity numbers you feed it.
Why it matters
Before your next session, pick one fidelity formula and stick to it. Write the rule in your protocol sheet. Share the sheet with your RBT. When you graph the child's data later, you will trust both the behavior line and the fidelity line. No more "maybe we drifted" doubts.

03Original abstract
Procedural fidelity is the extent to which components of an intervention are implemented as designed. Procedural fidelity is measured as a dependent variable and manipulated as an independent variable. In research and practice, procedural-fidelity data should be collected, monitored, and reported. Procedural fidelity as an independent variable has been investigated in humans using parametric analyses, and the current article summarizes some of the research conducted on the effects of procedural-fidelity errors in behavior-reduction and skill-acquisition interventions. Connections were drawn to applied animal researchers and the work of animal behavior practitioners to produce implications for practice with human and animal clients and suggestions for future research. Further, there are multiple ways to measure procedural fidelity, and different conclusions can be drawn based on the measure and computation method. The current article describes procedural-fidelity measures that are most applicable to animal behavior researchers and professionals.
