Dear researchers
One of assumptions exploratory factor analysis is multivariate normality distribution. How can multivariate normality distribution be elevated when we decide to run exploratory factor analysis?
Can it be checked by SPSS software?
I really appreciate your concern
Hamid
You'll need to test for multivariate normality, which is not supported in SPSS (unlike R).

Dear Hamid,
The normality hypothesis is mandatory only for some methods of factor extraction, such as the Maximum likelihood. If your data violate this hypothesis, you may try the principal axis method to extract the factors. To test the data multivariate normality in R, you may use the package MVN. https://cran.r-project.org/web/packages/MVN/vignettes/MVN.pdf
I support the suggestion made by Dr. Robson. Principal Axis method is non-parametric and overcomes the limits of parametric methods..
