ABSTRACT
Pathogenesisis is defined as the degree to which, when the needs of someone who depends on you conflict with your own needs, you do or do not take their conflicting needs into account (without awareness of its impact). Since, as described in chapter 18, it is understood to be an unconscious defense, not merely conscious malevolence, it is necessary to use a measurement technique capable of measuring unconscious processes. The Thematic Apperception Test (TAT) was an obvious choice. The Pathogenesis Index was an attempt to operationally measure this concept that was based on clinical observations in psychoanalytic therapy of patients with schizophrenia and their parents, plus observations outside of therapy of patients with schizophrenia and their parents, and the clinical and research literature available at that time.
