It depends on the nature of the multiple choice questions.  If a
Likert-type item is scaled poperly (or if you understand the scaling
properties very well), there's really no harm in analyzing it as if it
were a continuous variable.  If you are summing several Likert-type items,
which would be more desirable than analyzing separate items, there is even
less of a problem; again, this assumes that the items were constructed
carefully.
