#BIO-PSYCHO-SOCIAL APPROACH OF #HUMAN #BEHAVIOR

First of all, I must confess that for me such a model is or a plain truism or a meaningless tri-partition of a single object, that in essence doesn't allow any kind of partition.
It is as a reminder of the importance of a good doctor-patient relationship,"holistically"oriented, that I regard it as a mere truism.
I can not believe that any doctor can afford to be so unethical to the point of remaining oblivious to the social and psychological aspects of a patient seeking his/her attention, since these are so important as the biological.
As for a method of scientific study of diseases and diseased people, it faces a serious hindering: men and women are by no means a fusion of three separate layers. What gives rise to this apparent partition, whenever science takes the human being as an object of study, is not any ontological reality but rather a mere observational artifact. 
No researcher will ever find a living human body which is not,and at exactly that same instant, a psychological self living within a social context. This means that all events whose empirical data we may only  gather through one of the B-P-S lenses, as if they corresponded actually to 3 "layers", are entangled,  being quite impossible to separate them. Every time we think any phenomenon is a biological, a social or a psychological pure event, we have been deceived by a mirage!
