- Hops et al. (1995) defined interobserver agreement as a measure of consistency and, therefore, as representing a form of reliability. In contrast, Alessi (1988) described interobserver agreement as an estimate of objectivity that indicates the degree to which the data reflect the behavior being observed rather than the behavior of the observer.

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). Others have argued even more strongly.

Dec 1, 2019 · 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.

Johnston and Pennypacker (2009) deemed IOA as insufficient means of assessing reliability and identified intraobserver agreement—wherein a single observer repeatedly scores a video record-
In spite of vary-ing theoretical derivations, its definition is remarkably uniform: A reliable instrument is one with small errors of measurement, one that shows stability, consistency, and depend-ability of scores for individuals on the trait, characteristic, or behavior being assessed.

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.
Apr 30, 2023 · Moreover, crucial elements of optimum behavior measurement including reliability, accuracy, and validity are explored. Last, we describe strategies for calculating interobserver agreement (IOA) drawing on several examples designed to highlight differences between each of the IOA strategies.
