This is sort of a repost of this question, but there weren't any answers so I will ask it again and I will try to make it clear what my problem is.
My eventual aim is to find out the relationship between one independent variable and many dependent variables. Because I have many of these dependent variables I decided to use an Exploratory Facor Analysis to first reduce the number of items to fewer latent variables. Also, all these dependent variable are questionaires investigating similar, but not the same thing. And then I wanted to check whether my independent variable can predict some of the latent variables yielded by the EFA.
Now, I wonder whether I can throw my independent variable into the EFA as well and see on which latent variable it has the highest loading on? Or is that entirely unusual to do? And would it mess up my latent variables?
