类内相关系数(Intraclass Correlation Coefficient, ICC)是一种用于评估不同评估者对同一组数据的评分一致性或可靠性的统计指标。它常用于临床研究、心理学、教育等领域,特别是在需要多次测量或不同评估者评分的情况下。ICC值的范围在0到1之间,越接近1表示一致性越高。 ICC的理解 1、ICC的解释: ICC = 0:表示没...

类内相关系数(Intraclass correlation coefficient, ICC)是衡量同一组中不同观察之间相关性的统计量,通常用于评估测量工具的可靠性和一致性。在实际应用中,我们可以通过以下几种方法来计算类内相关系数: 1.单因素方差分析法:通过单因素方差分析来计算类内相关系数是比较常见的方法。在这种方法中,我们首先计算组内均方(...
我们通常检验的“信度”是指 the consistency between two or more concepts(两个或更多概念之间的一致性),这时我们确实是用Cronbach’s alpha,其实alpha只是根据Pearson r(即经典的相关系数)而计算出来的衍生物,而Pearson r 则是一种Interclass Correlation Coefficient(注意其中的“Interclass”,即“组间相关系数”,...

The intra-class correlation coefficient was computed to assess the agreement between three doctors in rating the anxiety levels in 20 individuals. There was a poor absolute agreement between the three doctors, using the two-way random effect models and “single rater” unit, kappa = 0.2, p = ...
An intraclass correlation coefficient, according to Koo & Li: Less than 0.50: Poor reliability Between 0.5 and 0.75: Moderate reliability Between 0.75 and 0.9: Good reliability Greater than 0.9: Excellent reliability Intraclass Correlation Coefficient in R ...
