I'm not an MD, so I can't judge these scales. If one scale claims to be better than another, then it must allow a more reliable and valid measurement. This is verifiable (to some extent). Therefore, I do not fully understand the problem. What strikes me, however, is that some strange phenomena are very quickly referred to as "marketing". If so, they are amateurish marketing attempts by practitioners or persuasion based on information asymmetries. It's not necessarily what researchers are investigating when they want to understand why customers act in a certain within a certain context.

Thanks a lot for your answer. I agree with your opinion about the validity of different scoring scales and on easily attributable »marketing«. I am bothered by too much talking of health assesment indexes, without the consideration of their limitations, in the purpose of promotion and sale. And believe me, it is far from being amateurish.

I agree that pharmaceutical induatry has developed top marketing strategies in order to gain better competitive position and even for patients it is sometimes frustrationg. On the orher hang, measuring the effwcts and satisfaction with medical/ pharmaceutical treatment can contribute to its improvement...hard to say where the "golden middle" is.
