The process of developing the final version of the Impasses, Ego state and Drama Triangle Role Inventory (in short - ZESUI) presented in this article involved repeated iterations over four years. The scale is based on the Transactional analysis theory of personality, interpersonal styles and pathology. The statistical method used in the process of the instrument development, with specific attempts to increase the factor saturation and items internal consistency is exploratory factor analysis, more specifically methods of principal component analysis. The questions within the inventory include the relevant aspects of the diagnosis (assessment) of the Ego state, Impasses and Roles profiles. It consists of 62 items which measure three types of Impasses: Type I, II and III, nine Functional Ego States and three Drama Triangle Roles: Rescuer, Persecutor and Victim.
