You say you are
building scales. What is the response scale on the items
you are considering? Usually scales are built of strictly
interval level items (e.g., Z's or temperature) or of items that
are not severely discrepant from interval level such as extent
response scales or Likert response scales.
How extensive is your missing data? Do you know why data is
missing for some items?
Were you thinking of CATPCA rather than FACTOR for EFA?

Hello!
Thank you so much for this interesting discussion. Unforunately as
far as I understand the suggestions on using EM for EFA don't
solve the problems for categorical variables with missing values,
since EM cannot be applied to categorical data in SPSS (and in
general??). On top of that, SPSS won't compute Little's MCAR test
for categoriacal variables
Does someone have any suggestions for dealing with missing values
on categorical variables? My proximal goal is to build scales
using EFA and reliability analyses. I know MI is the state of the
art, but as it has already been noted, spss doesn't produce pooled
results for EFA yet.
I appreciate any help/advice/comment!!!!
