The purpose of this study was to determine the factors and facets of Five Factor Model in people with
borderline and schizotypal personality traits.190 Kharazmi university students completed three
questionnaires: Goldberg Inventory, Borderline personality Inventory (BPI) and Schizotypal Personality
Questionnaire-Brief (SPQ-B). Participants, according to cut off points of Borderline personality Inventory and
Schizotypal Personality Questionnaire-Brief, were classified into four groups: high borderline trait, low
borderline trait, high schizotypal trait and low schizotypal trait. When the results of discriminant function for borderline and schizotypal groups were obtained, people who were determined as real borderline and real schizotypal were classified into
two groups named typical borderline and typical schizotypal. Data were analyzed using discriminant
analysis.SPSS.22 was used in order to analyze data. Findings showed that both factors and facets of Five
Factor Model could determine people with borderline and schizotypal personality traits in all six groups. In
the factor level, openness to experience and extraversion and in the facet level, gregariousness, orderliness, tranquility and organization were the best discriminants in typical borderline and typical schizotypal groups respectively.
