Dear Kristine:

As one variable can take only one value, you must use as many variables 
as there are possible values.  If you have 5 possible responses ("Do you 
have any of the following 5 symptoms?"), you need 5 variables, each with 
3 possible values, "present", "absent", "unanswered".  I don't see an 
easier way.



Dear Epi-data users:

What is the best way to deal with multiple response questions?
