Chance Agreement In Inter Rater Assessment

Liao, S.C., Hunt, E. A., and Chen, W. (2010). Comparison between Inter-Rater`s reliability and the Inter-Rater agreement for performance evaluation. Annal. Acad. Med. Singapore 39, 613. In Kappa`s first case, the probability of consent became „1,“ making the P equal to „0“; Considering that, in the case of Gwets AC1, the probability of an agreement was not equal to „0“. The reliable exchange index (RCI) was used to calculate the smallest number of T-points required for two ELAN scores to differ significantly from each other. We used two different reliability estimates to demonstrate their impact on the measures of the agreement.

First, CCI, which was calculated for the entire population studied, was used as an estimate of the reliability of ELAN in the population of this study. Because CCI is calculated within and between dentendances and not between certain groups of advisors, this is a valid approach for estimating overall reliability in both rating subgroups.

A serious error in this type of reliability between boards is that the random agreement does not take into account and overestimates the level of agreement. This is the main reason why the percentage of consent should not be used for scientific work (i.e.

doctoral theses or scientific publications). This study was conducted in 67 patients (56% of men) aged 18 to 67 years with an average SD of 44.13 ± 12.68 years. Nine counsellors (7 psychiatrists, a psychiatrist and a social worker) participated as interviewers, either for the first or for the second, which took place 4 to 6 weeks apart. Interviews were conducted to establish a diagnosis of personality disorder (PD) based on DSM-IV criteria. Cohens Kappa and Gwets AC1 were used and the degree of correspondence between the counsellors was assessed for a simple categorical diagnosis (i.e., the presence or absence of a disorder). The data were also compared with a previous analysis to assess the effects of characteristic prevalence. Fleiss` Kappa can also be applied to ordination data when weights are introduced and used to take into account larger and minor variations of the spleens of each other. The initial idea of a weighted approach of Kappa is based on ordinal attitudes that must penalize longer distances between the denères [6]. The most frequently used weights for this approach are linear and square [24]. However, both parties are criticized for their arbitrary forms and it can be shown that the linearly weighted kappa corresponds, under certain conditions, to a match of product moment [6]. With regard to quadratic weighting, it corresponds to the definition that it corresponds to an intra-class correlation [21]. This means that these measures are no different from the approaches described above.

There is also a Kappa coefficient for cardinal scales, which corresponds asymptotically to the internal intraclass correlation (ICC), estimated by a random double-sided ANOVA effect, as discussed in 1973 by Fleiss and Kappa [9]. In some cases, Fleiss` Kappa may return low values, even if consent is indeed high. That is why he has been tempted to correct this situation [8]. where cj represents the degree to which the coder J systematically deviates from the average, and rcij represents the interaction between the subject gap and the code gap.
