Higher levels of CCI suggest better irregage, an ICC estimate of 1 indicating perfect matching, and random matching of 0. Negative CCI estimates indicate systematic discrepancies and some ICCs may be less than $1 for three or more codes. Cicchetti (1994) proposes cutoffs often cited for qualitative ratings of agreements based on ICC values, ERRORS are bad for ICC values below 40, fair for values between .40 and .59, good for values between 0.60 and 0.74 and excellent for values between 0.75 and 1.0. The resulting CCI is high, ICC – 0.96, indicating an excellent IRR for empathy assessments. Based on an incidental observation of the data in Table 5, this strong CCI is not surprising, as differences of opinion between coders in relation to the range of results observed in the study appear to be low and there does not appear to be any significant domain restrictions or serious breaches of normality. Reports on these results should detail the specifics of the chosen ICC variant and provide a qualitative interpretation of the impact of the CCI estimate on agreement and power. The results of this analysis can be reported as follows: In research projects in which you have two or more advisors (also known as “judge” or observer) responsible for measuring a variable on a category scale, it is important to determine whether such advisors agree. Cohens Kappa () is such a measure for the Inter-Rater agreement for categorical scales when there are two advisers (the Greek letter is “kappa” in tiny). Cohen`s number was executed to determine whether there was agreement between the verdict of two police officers that 100 people were behaving normally or suspiciously in a shopping mall. There was a moderate convergence between the judgments of the two officers, n.593 (95% CI, .300 to .886), p < .0005. The ER assessment quantifies the degree of agreement between two or more coders who conduct independent assessments of the characteristics of a number of subjects.

In this article, subjects are used as a generic term for people, things or events assessed in a study, such as the number of times a child reaches for a caregiver, the level of empathy displayed by an interviewer, or the presence or absence of psychological diagnosis. Coders are used as a generic term for people who assign innotations in a study, for example. B trained scientific assistants or randomly selected participants. Cohen (1968) proposes an alternative weighted kappa that allows researchers to penalize differences differently because of the magnitude of differences. Cohen`s weighted Kappa is generally used for category data with an ordinal structure, for example. B in an evaluation system that categorizes the high, medium or low presence of a particular attribute.
