   Nov 24, 2022 · Despite disagreements regarding the general importance of IOA and the merits of various strategies for calculating and reporting IOA (see Kostewicz et al., 2016), IOA had come to be widely accepted by the end of that decade. For example, in 1982, Page and Iwata contended that “Reporting indexes of observer agreement is now a necessary component of applied behavior analysis research” (p. 100).

   Dec 1, 2019 · The combination of time alignment and multivariate IOA methods is unique and is the first approach to address both of the key issues facing IOA assessment of time-and-motion data. By applying multivariate IOA methods to time-aligned data, rather than univariate as done by previous authors, this allows flexibility in terms the number and type of variables simultaneously assessed.

   Thus, the current review evaluated the data collection procedures, reports of measurement assessment, and the use of IOA, reliability, and accuracy in a sample (n = 2,091) of behavioral studies published from 1958 to 2013. Behavior analysts have a variety of tools and techniques available for collecting behavioral data.

   How do researchers and practitioners use IOA?

   • Researchers and practitioners use measures of IOA to (a) determine the competence of new observers, (b) detect observer drift, (c) judge whether the definition of the target behavior is clear and the system not too difficult to use, and (d) convince others of the relative believability of the data.

   What is an example of an IOA assessment?

   • For example, a task performed by a physician could involve both a patient and a nurse. Table 2. Proportions (%) of time for each category of the eight variables included in the example IOA assessment. Proportions represent aggregate values across the two observers and five observation sessions.

   How is IOA determined?

   • To determine IOA, two or (very rarely) more observers simultaneously record data for the same response (s), and the correspondence in the data they record, which is IOA, is determined. Although it was not reported in seminal applied behavior analysis articles (e.g., Ayllon & Michael, 1959), IOA generated much interest in the 1970s.

   Should I use the most relevant IOA statistic?

   • As a general rule of thumb, users should only use the most relevant IOA statistic given the nuances of their data collection system and the attributes of the data set, thereby nullifying any need to copy and paste the data across spreadsheet tabs.

   How do you calculate IOA for data obtained by event recording?

   • IOA for data obtained by event recording can be calculated by comparing (a) the total count recorded by each observer per measurement period, (b) the counts tallied by each observer during each of a series of smaller intervals of time within the measurement period, or (c) each observer’s count of 1 or 0 on a trial-by-trial basis.

   Is IOA a measure of agreement?

   • In studies using direct observations of clinical work, there is considerable variation in how IOA has been assessed, if at all, and the reporting of those methods “is often incomplete and inadequate” . Of the studies addressing this aspect of data quality, most report a measure of agreement.

   Direct observation of behavior has traditionally been a core component of behavioral assessment. 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 ...
