Answer:
Humanistic therapeutic approach (according to Carl Rogers) is basicaly creating the client (he did not use term patient) an atmosphere when he or she can feel fully accepted and let himself/herself fully experience and reveal their nature. This leads to a full development of personal potentials (self-actualizing tendency).
Therapist behavior - "unconditional positive regard" - contains, unjudgmental listening, congruency, and full acceptance of the person as it is (does not mean the acceptance of his/her all behaviors).
