The Relationship between Schizotypal and Borderline Personalities among Non Clinical Samples

Schizotypal and borderline personalities, as borderline states of psychosis, are more vulnerable to psychosis. So, these disorders can be overlapped with together. The present study explored the possibility that schizotypal and borderline features are significantly related together among non clinical samples. A group of 749 normal participants (380 male and 369 female from collages of Shiraz University) took part in this research. Participants answered to schizotypal personality (STA) and borderline personality (STB) scales. Using the multivariate regression analysis model, results indicate that all three components of borderline personality (hopelessness, Impulsivity, stress related paranoid/dissociative symptoms factors) significantly predict schizotypal personality. It was, also revealed that only two components of schizotypal personality (unusual perceptual experiences and paranoid suspiciousness/social anxiety factors) significantly predict borderline personality, but magical thinking factor is not predictable factor in this relation. Results were discussed in light of previous research results and showing that overlapping between borderline and schizotypal personalities indicate serious problem in these two personalities studies and research context.
