To answer your last side point: I think you'll find that in 1971 behaviour therapy was concerned with phobias, OCD, and other such behavioural problems which could be defined as 'current, repetitive, and measurable' - the mantra of my early days of training. If a behaviour therapist had problems which fell outside of this arena, then of course they would seek a different kind of therapy.

Here's a quote from Lazarus: “In the late 1960s I started adding
‘cognitive’ methods to the more objective
behavioral techniques and found a
synergistic outgrowth. Thus, Behavior
Therapy and Beyond was one of the first
books on (what has since been termed)
‘cognitive behavior therapy.’ The main
intent of the book was to expand the
legitimate base of behavioral operations.
Thus, in addition to the more usual
behavioral methods such as systematic
desensitization, graded sexual assignments,
and assertiveness training, a variety of
cognitive methods and other innovative
techniques were carefully described."
