Webplot method, the Intraclass Correlation Coefficient (ICC) and the Content Validity Index (CVI), were used. The Spearman coefficient was used to estimate concurrent validity. Results of the analysis of Bland-Altman plots showed that there is agreement among experts, since mo st points were found to be within the expected limits of agreement.
