^a I-CVI (content validity index) = number of experts providing a rating of 3 or 4/number of experts
^b p_c (probability of chance occurrence) = [N!/A!(N-A)!] × 0.5^N, N = number of experts; A = number of experts agreeing on a rating of 3 or 4
^c k* (modified kappa) = (I-CVI-p_c)(1-p_c)
^d Evaluation criteria for level of content validity: relationship between I-CVI and k*; excellent validity = I-CVI ≥ 0.78 and k* >0.74 (****); good validity I-CVI < 0.78 and ≥ 0.60 and k* ≤0.74 (***); fair validity I-CVI < 0.5 and ≥ 0.40 and k* ≤0.59 (**); poor validity I-CVI < 0.4 and k* <0.40 (*)
