I surmise Behavioral Health type terms refer to B F Skinner.
B. F. Skinner | Department of Psychology

When I studied psychology in college in the early 1980’s we differentiated the talk therapy of Freud to the behavioral therapy of Skinner.

He’s the father of Experimental Psychology vs. Clinical Psychology, in which my sister and BIL have Ph.D’s....bad choice for them, no jobs.

My new psychiatrist tells me they are changing the DSM to do away with many diagnoses and focus on neuroscience instead.
