What Is Typically Used To Calculate Interobserver Agreement

Comment: Quantification of compliance in the resumed psychiatric diagnosis.

Archives of General Psychiatry, 44, 172-178. Seventeen association measures for observer reliability (Interobserver agreement) are verified and calculation formulas are given in a common scoring system. An empirical comparison of 10 of these measures is made during a number of potential background check results. The effect on frequency, error frequency and percentage and correlation error values are analyzed. The question of what is the “best” measure of the Interobserver agreement is debated with respect to critical issues that should be considered behaviouralists and has developed a sophisticated method for assessing behavioural changes that depend on a precise measurement of behaviour. Direct observation of behaviour is traditionally one of the carriers of behavioural measurement. Therefore, researchers need to address psychometric properties, such as the .B the Interobserver Agreement, of observational measures to ensure a reliable and valid measurement. Of the many indices of the Interobserver agreement, the percentage of the agreement is the most popular. Its use persists despite repeated reminders and empirical evidence that suggests that it is not the most psychometric statistic that determines interobserver agreement because of its inability to take into account chance. Cohens Kappa (1960) has long been proposed as a more psychometric statistic for the evaluation of the Interobserver agreement.
