[Clinico-statistical data on psychologically traumatic experiences in various forms of psychogenic disorders].

On the basis of clinico-psychopathological studies of patients with different forms of neurosis and the use of the level of mental development concept a special technique was elaborated to detect by questionnaires the predilective "key" psychotraumatizing experiences in the main forms of neurosis (neurasthenia, obsessional neurosis, hysterical neurosis and a special clinical form--explosive reactions). It is assumed that these forms of psychogenic reactions, as well as their respective "key" experiences (exhaustion-overstress, a disturbance of a habitual stereotype, infringement of egocentrism, a negation of concession) form a certain hierarchic system. The "key" character of some types of pathogenic experiences for clinical forms of psychogenic reactions was confirmed statistically. The data indicate a different degree of clinico-nosological delineation of some forms of the reactive states.
