# How to reverse the sign of factor loadings in factor analysis? [duplicate]

I'm doing a factor analysis and using the resulting factors in a regression. I'm using SAS. A number of the variables load positively on a factor. In order to make it easier to interpret in the final regression, it would be better if the loadings were negative.

Is there a way I can rotate the factor so the loadings are negative? Could the factors be multiplied by $-1$?
