Abstract There has been considerable debate regarding the relationship between obsessive compulsive disorder (OCD) and the psychotic phenomena. The present study explored the possibility that schizotypal personality, according to the three factor model, and obsessive features are significantly related to each other among non clinical samples. The current study was conducted using a corelational research design. A group of 262 normal participants (105 males and 157 females) took part in this research. Participants responded to the schizotypal Trait Questionnaire A form (STA Claridge & Broks, 1984) and Padua Inventory (PI Sanavio, 1980) scale. Positive correlations were found between schizotypal personality and obsessive features. Using the multivariate regression analysis model, results indicate that two components of schizotypal personality (unusual perceptual experiences and paranoid suspiciousness/ social anxiety factors) significantly predict obsessive compulsive scores. It was, also revealed that magical thinking components of schizotypal personality did not predict obsession. Results are discussed in light of results of previous clinical research and anxiety-psychosis spectrum hypothesis.
