[The characteristics of the manifestation of extraversion and neuroticism in the families of schizophrenia patients].
40 schizophrenic patients, their 40 healthy relatives as well as 40 healthy control individuals without any hereditary predisposition to mental disease were examined by means of H. Eysenck questionnaire according to Extraversion, Neuroticism and Lie scale. Schizophrenic patients had higher ratings on the Neuroticism scale while their relatives were more extraverted as compared with controls. Both the patients and their relatives had higher ratings on the Lie scale. Genetic mathematical analysis revealed that the hereditary contribution to determination of these signs did not exceed 4%. It was suggested that personal peculiarities have influence on the realization of hereditary predisposition and that the very peculiarities may be transformed under the influence of either this predisposition or disease.
