Inter-observer agreement (IOA) is a key aspect of data quality in time-and-motion studies of clinical work. To date, such studies have used simple and ad hoc approaches for IOA assessment, often with minimal reporting of methodological details.

Nov 24, 2022 · They emphasize that “although IOA is not a direct indicator of the validity, accuracy, or reliability of measurement, it has proven to be a valuable and useful research tool in applied behavior analysis” (Cooper et al., 2020, p. 119).

However, systematic observational data is not intrinsically reliable and valid. It is well known that observer accuracy and consistency can be influenced by a variety of factors. Therefore, interobserver agreement is frequently used to quantify the psychometric quality of behavioral observations.

Data collection assessment method indicators (see Table 2) differentiated the methods used by experimenters to assess DVs and determine the level of reporting (i.e., partial or full). The indicators corresponded with the three broad methods for assessing measurement: IOA, reliability, and accuracy.

Although general parameters for how much IOA is needed have been suggested (Bailey & Burch, 2018), it is unknown if the total number of sessions with IOA might impact the IOA coefficient. In this study, IOA was reanalyzed using functional analysis data at various cutoffs.
