Schizotypy is phenotypically associated with neuroticism. To reveal the origin of this association, we assessed 3,349 (1,449 monozygotic, 1,105 dizygotic [DZ] same-sex and 795 DZ opposite-sex) twins on a 12-item version of Chapman's Psychosis-Proneness Scales and the short form of the Eysenck Personality Questionnaire-Revised as measures of schizotypy and neuroticism.

Evidence suggests that the structure of psychosisproneness in the general population may involve three distinct related dimensions.

Raine’s Schizotypal Personality Questionna...
