This method of psychotherapy evolved from Freudian psychoanalysis and is based on the same theories that the treatment works by bringing the unconscious into conscious awareness, achieving insight, resolving neurotic conflict, and working through resistance and the transference among others. However, this method, which is often considered standard or at least traditional among many psychiatrists and psychologists, may involve a shorter course of less frequent sessions and no psychoanalytic couch. The psychotherapist usually faces the sitting patient.
