Juanito,
 
I would be reading what Denny Borsboom has to say about validity, rather than Messick. There is plenty of "mess" in Messick!

Hello Rasch modelers,
 
I want to know how Rasch validate an instrument.  That is, what is the general procedure for testing validity and reliability of an instrument using Rasch methodology?  Comments are welcome.
 
Thank you.
