Measuring procedural fidelity helps behavior analysts assess staff performance and make decisions about a treatment's effectiveness. However, there is limited research comparing different methods of measuring procedural fidelity. Therefore, we systematically replicated a study that examined how procedural fidelity of discrete-trial-instruction sessions varies depending on the measurement system and calculation. We scored videos depicting behavior technicians conducting discrete-trial instruction with a child with autism and did not permit data collectors to pause, rewind, or fast-forward to simulate a live session. Specifically, we compared individual-component and global fidelity from the occurrence/nonoccurrence method and all-or-nothing by component method. Like previous research has demonstrated, our findings indicated that global values were likely to mask component errors, whereas the all-or-nothing by component method was less likely to do so. When data collected in the current study was compared to those in previous research, interobserver agreement was high for both occurrence/nonoccurrence and all-or-nothing by component methods. Overall, the procedural-fidelity values obtained from each study differed minimally. These results suggest that both measurement methods yield consistent results whether derived from recorded sessions with the ability to pause, rewind, and fast-forward or simulated live sessions. Differences that were obtained are discussed in detail with particular emphasis on connecting our findings to the utility of procedural-fidelity assessment in practice.
