Structure of schizotypal traits in the Russian population

Establishing the structure of schizotypal traits and its cross-cultural and demographic universality is an important condition for increasing the effectiveness of prognosis of schizophrenic spectrum disorders and basic research on their etiology. The present study aimed to explore the structure of schizotypal traits measured by the Schizotypal Personality Questionnaire (SPQ-74) in the Russian population. Exploratory and confirmatory factor analyses of the factor structure of SPQ-74 were performed using a sample of 1316 people of a wide age range. It is shown that, in the Russian population, the four-factor «paranoid» model of N. Stefanis et al. had the best fit for the data. The multivariate confirmatory analysis evidenced the gender invariance of the model.
