Confirmatory factor analysis techniques were applied to test how competing models (unifactorial, bifactorial, and trifactorial) could be used to explain the structure of schizotypal disorder as defined in DSM-III-R and DSM-IV. Subjects were 538 nonpsychotic psychiatric outpatients and a replication sample of 225 nonpsychiatric patients and control subjects, interviewed by clinicians using the Structured Interview for DSM-III-R Personality Disorders. The study found that the best-fit solution encompassed three factors: cognitive-perceptual, interpersonal, and oddness. Future studies may benefit from considering schizotypal personality disorder as composed of three factors that may indicate the existence of three underlying (dys)functional systems.
