Hi,

I have responses on Healthcare perceptions on 20 questions (likert scale of 5).
Using PCA Varimax rotation I got 5 factors. They are not correlated.
Is it correct to use factor analysis (second order) for the variables
in the first factor to get 2 factors? (I have read in a book that one
can use 2nd order factor analysis only if one has used oblic
rotation).
After getting 2 factors from the first factor, I now have 6 factors
and some of them are  correlated with these two new factors.

Is this corect procedure? If not what will be the correct procedure?

After getting 6 factors I used these factor scores as covariates and
used multinomial regression. I am getting expected results. But not
sure if I have followed correct procedure.

Factor scores should be correlated  or not ? When I did PAF varimax,
or obline, factor scores correlated.
Which will be the best model?
