Confirmatory factor analysis is commonly used in testing multidimensionality of a test.However,when the factors are highly correlated with each other, a higher order factor may exist which implies that the measure is unidimensionnl.Through comparing an oblique factor model with a higher order factor model, multidimensionality or higher unidimensionality can be tested by CFA.This article offers a bootstrapping experiment of a multidimensional creativity measure,and demonstrated that the CFA is a better tecnique in this field.
