† The intraclass correlation is not reported for dichotomously scored items; Cohen's Kappa is not reported for polytomously scored items.
NOTE: Cohen's Kappa is a measure of reliability that is appropriate for items that are dichotomously scored. The intraclass correlation coefficient is most appropriate for items with more than two categories.
