On Various Intraclass Correlation Reliability Coefficients
نویسنده
چکیده
This paper briefly reviews the most frequently used and misused intraclass correlation analysis of variance (ANOVA) reliability measures. Recommendations are made for the one-way ANOVA intraclass correlation and against the use of several coefficients: Winer's so-called "anchor point method," KuderRichardson Formula Number 20, and the Spearman-Brown prediction formula. The computation of the intraclass correlation coefficient via two-way ANOVA is not encouraged. Several uses and misuses of reliability coefficients applied to dichotomous data are also illustrated.

Intraclass correlations: uses in assessing rater reliability.
Reliability coefficients often take the form of intraclass correlation coefficients. In this article, guidelines are given for choosing among six different forms of the intraclass correlation for reliability studies in which n target are rated by k judges. Relevant to the choice of the coefficient are the appropriate statistical model for the reliability and the application to be made of the re...

There are currently few studies in the literature concerning the reliability and validity of the quantification of parameters of muscle architecture using the technique of ultrasound. The aim of this study is to apply the technique of ultrasound imaging to quantify pennation angle of gastrocnemius muscle (medial and lateral) and to determine the reliability and reproducibility of these measures...
متن کاملTest-retest reliability of three Dynavision tasks.
The test-retest reliability of three Dynavision tasks of graded difficulty was estimated as high, with intraclass R correlation coefficients ranging from .88 to .97, and paired correlation coefficients ranging from .74 to .92. Recommendations are made for reliable testing procedures.
