Anyone,
I'm wondering if anyone knows if it is appropriate to use the Bland-Altman approach (as implemented
in STATA) for comparing the measurements from two separate rating mechanisms. That is, I'm checking
whether two rating sytems that rate the same population of objects can be "tested" for their
equivalence through the Bland-Altman method (plots, etc.).
In my perusal of literature that mentions use of the Bland-Altman method, I have only seen its
application in the comparison of two measurement devices that measure 'physical qualities" (as in
medical/health research). Has anyone seen an application (and a defensible one) of the method in
psychology, sociology, or economics, where there may be an interest in exploring the equivalence of
two sets of ratings of the same objects/persons/constructs....
Thanks for any advice,
Willard Hom
