The author considers psychoanalytic treatment to be most effective when based upon an interactive, intersubjective conception of normal and pathological psychic development. By internalizing pathological and pathogenic relationships during childhood, the person builds up a troubled internal relational pattern; it determines his her choices and ensuing relationships and thus perpetuates his her pathology. When it appears in the psychoanalytic relationship this pathological relational style can be analysed and resolved, while a new relationship, promoted by the psychoanalyst, is begun. It aims at fostering the person's development and mental health. This new, healthier relationship is progressively integrated into the patient's everyday life. Consequently the internal relationship pattern itself, through the person's new experiences, changes. Psychoanalysis comes to an end when the new internal relational pattern is consolidated. Therefore the psychoanalytic cure is seen as a process of transformation; and the psychoanalyst is its agent. Therein, the author maintains that counter transference precedes transference and is the driving force of the curing process. The author states that: precedence and priority should be given to counter-transference.
