WebThe CA-ICC between individual ratings is 1 because the scores from rater 1 and rater 2 differ by a constant value (two points) for all targets. That rater 1 gives lower scores than rater 2 … An intraclass correlation coefficient (ICC) is used to measure the reliability of ratings in studies where there are two or more raters. The value of an ICC can range from 0 to 1, with 0 indicating no reliability among raters and 1 indicating perfect reliability among raters. See more Here is how to interpret the value of an intraclass correlation coefficient, according to Koo & Li: 1. Less than 0.50:Poor reliability 2. Between 0.5 and 0.75:Moderate reliability 3.
