There are numerous factors regarding psychiatric or mental illness.

I will agree that psychology in general relies on behaviors and actions to determine diagnosis, but that's not the whole kit and kaboodle.

There's also family history, genetics, hormone levels.
As for the physiological testing-most good (I say "good" for a reason) psychiatrists or psychologists will send a patient for medical tests to determine the possible cause of any psychiatric ailment.

MRIs, PET scans, as well as EEGs are often implemented to determine if there's abnormal patterning or other possible issues regarding one's physiology.

Further, perhaps the single most mysterious psychiatric illness is still not well understood, and the community at large was hopeful a decade ago when the dopamine theory was prevalent for explaining schizophrenia. Now of course they feel it's also genetic

We should all remember that medicine as a whole, in its current iteration is only a century or so old and modern science a few centuries older than that.

Show me color without an eye to perceive it. It may exist but that has noting to do with consciousness.

By using color they can tell the basic chemical make up of stars.
