The only problem I have is should I use factor analysis to find the 
a-priori dimensions.  I always follow up with a Rasch Analysis. Two 
things were left out   The number of types of questions makes a big 
difference and the culture of the respondents.  With Rasch, this does 
not seem to be the case to any degree.
