Can you please recommend a text or article citation for cross loading of items on factors? I have been told (courses) and seen (Nunnally 1994 cited, but no page number) that there should be at least a .2 difference if cross loading occurs. I have eyeballed Nunnally, but can not find that criterion.
I don't know of any useful rules regarding the size of cross-loadings. I would look at interpretability and significance. You might also want to look at the Cudeck and O'Dell paper that is referenced in the user's guide.
I think rules about sizes of loadings may be from a time when there were no standard errors available for estimated loadings - now they are available, also for EFA which is the topic discussed in Cudeck and O'Dell.
Substantively, of course you don't want large cross-loadings if they were not hypothesized, but there may be a good substantive interpretation of their existence and inclusion. They are not hurtful per se.
