[Schizotypy Personality Questionnaire Brief Revisited (SPQ-BR) Hungarian adaptation and interpretation of factors].

ABSTRACT

INTRODUCTION: The purpose of the Schizotypy Personality Questionnaire - Brief Revised (SPQ-BR) is to help the diagnosis of schizotypial personality disorders within the framework of the DSM-5 and identification of people with an increased vulnerability towards schizophrenia related symptoms. The aim of our current study is twofold; validation of the SPQ-BR's Hungarian adaptation and investigating it's latent structure. METHODS: The sample consisted of 1702 Hungarian university students and university graduated persons. Exploratory factor analytic procedures were performed, cross-validating their results by the use if confirmatory factor analysis. RESULTS: The results suggested that the Hungarian SPQ-BR is best represented by a model of the hierarchical structure, reflected by seven first order factors, and two higher order dimensions of positive and negative symptoms. On lower order factors males were shown significantly greater constricted affects, and proneness to eccentric behaviors and unusual perceptions, while females were characterized by higher magical thinking, next to stronger social anxieties. Gender differences in the Ideas of references - Suspicion and odd speech scales were found to be non-significant. Concerning it''s validity with other scales we found that magical thinking and unusual perceptions from the positive symptoms significantly positively correlated with the magical ideation (MI), anxiousness (ASI), and self-concept clarity (SCCS) scales, next to a negative correlation between unusual perceptions and the self-esteem (RSES) scale. Among the negative symptoms the No close friends-Constricted affect and the Ideas of references - Suspicion subscales showed significant negative linear associations with the ASI, SCCS scales. CONCLUSION: The Hungarian version of the SPQ-BR showed adequate psychometrical properties, it was found to be reliable.
