The topic sounds interesting. I believe that When we do not have an agreement
between Rach model and Theoretical model, there are three possibilities
1. Rasch model requires revision
2. Theory requires revision
3. Items requires revision
One of the 1, 2, or 3 should be revised.
At the moment, I am not willing to choose 1 - the Rasch model seems to be best
we have for our task of constructing and monitoring variables at this point.
Here's an example of Rasch meets Piaget, where revision to Piaget's theory AND
Inhelder's methodology are recommended:

méthode clinique. Archives de Psychologie, 63, 231-255.
