Soon after Empedocles, Hippocrates (460-370 BCE) incorporated the four temperaments or humours into his medical theories: sanguine (pleasure-seeking and sociable), choleric (ambitious and leader-like), melancholic (analytical and quiet), and phlegmatic (relaxed and peaceful). These may have their origins in ancient Egypt or Mesopotamia. I don't know how these ideas were conflated and incorporated into astrology.
As you can tell, none of these early descriptions of temperaments represents a disturbance, and as such they can be considered as stable dimensions of personality. What I think Eysenck and later psychologists did was interpret these dimensions in such a manner that suggested disturbances or unstable psychological states. The difference, I believe, is that in astrology the personality dimensions may be disturbed into such states but recovery is expected because psychological states are not permanent as dimensions are. Eysenck and others seem to take certain psychological states as being permanent and I think this has no place in astrology.
Thus in Eysenck's Personality Inventory (EPI) test, we have E (extraversion - sociability) and N (neuroticism - emotional stability) each with continuums between + and -. E+ is sociable and outgoing, E- is quiet and reserved, N+ is emotional and easily upset, N- is calm and not easily upset. Now, how often do you encounter people, for example, in the E+N+ quadrant (outgoing and easily upset emotionally)? Are these people in your everyday world? Is this really a personality dimension or a psychological state? You may encounter someone from this quadrant like Mayor Rob Ford, but such people are unstable and definitely need professional help. It is not a true personality dimension.
The beauty of astrology is that it describes both personality dimensions and psychological states but the states are assumed to be under the control of the native, whereas the dimensions are not. That is why astrology cannot predict with certainty what the state might be at any given time. This is a different paradigm than the E and N theories, which I now believe to be a corruption.
