* Interpretation of I-CVIs: If the I-CVI is higher than 79 percent, the item is appropriate. If it is between 70 and 79 percent, it needs revision. If it is less than 70 percent, it is eliminated [60]. ** The formula of content validity ratio is CVR = (Ne − N/2)/(N/2), in which the Ne is the number of expert panelists indicating “essential” and N is the total number of panelists. [60]. *** Slightly revised after content analysis and pre-testing.
