The instrument (say, to measure personality) was developed using Rasch Model using sample data from a population of professional people.. Assuming that the instrument now is valid and reliable based on Rasch.  Can I use the instrument to measure personality to uneducated people (or say sample that are not from a population of professionals)?
Thank you for any comment.
