Personality dimensions, schizotypal and borderline personality traits and psychosis proneness

The present study was aimed at assessing the relationship between personality dimensions and psychopathological traits of psychosis proneness. Consistent with this goal, a psychometric study was carried out involving a sample drawn from a population of first year university students (n = 735). Subjects completed Eysenck and Eysenck's scales measuring the three major descriptive dimensions of his personality model (Psychoticism, Extraversion and Neuropticism), Claridge and Broks's scales of schizotypal and borderline traits and Chapman and Chapman's scales of Physical Anhedonia, Social Anhedonia, Perceptual Aberration and Magical Ideation traits. Results suggest that different sets of psychopathological traits can be identified in psychosis proneness which relate to the three personality dimensions. These findings seem in accordance with high-risk and clinical research studies. Implications for future research on psychosis proneness including personality variables are discussed.
