The aim of the present study was to replicate the factor structure of the STA, a measure of schizotypal personality, reported by Hewitt and Claridge (Personality and Individual Differences, 10, 323-329 1989). Factor analysis was carried out on data collected from 268 normal subjects who completed the STA. A three factor solution yielded results very similar to those reported by Hewitt and Claridge. Factor one was characterized as magical ideation, factor two as unusual perceptual experiences, and factor three as paranoid ideation and suspicion. These data largely confirm the validity of the Hewitt and Claridge (1989) STA subscales.
