I have 2 measures -- one of anxiety (scored 0 or 1), and one for depression (scored 0, 1, 0r 2).
I would like to test a theory called the tripartite model of anxiety and depression whereby there are 3 factors underlying these constructs.
Given that one measure is score (0, 1) and the other is scored 0, 1, 2, can I pool the items from the two measures and load them on the respective factors as described in the literature? Or do I need to use a specialized technique given that the two measures have different scoring?
