^a Content Validity Ratio, ^b Content Validity Index, ^c Kurtosis is a measure of whether the data are heavy-tailed or light-tailed relative to a normal distribution ^d Skewness is a measure of symmetry, or more precisely, the lack of symmetry, ^e The calculated values of t for all factor loadings of the first and second order are greater than 1.96 and are therefore significant at the 95% confidence level, ^f The specific value, which is denoted by the Lamda coefficient and the statistical symbol λ, is calculated from the sum of the factors of the factor loads related to all the variables of that factor
