Recommendations for EFA with Dichotomous Data

[RLPJ]

Are any syntactical changes needed for the commands I use in SAS when doing an exploratory factor analysis with dichotomous data? My data set has a sample size of 277 with 32 variables, 7 of which are true/false and 25 of which are multiple choice, but all of which have a right answer. Thank you!

This looks like IRT.  Do you have access to SAS/STAT13.2?  If so, you might look at PROC IRT for a start.
