title: Chinese version of the Schizotypal Personality Questionnaire: Factor structure replication and invariance across sex.
abstract: BACKGROUND
  The Schizotypal Personality Questionnaire (SPQ) is a self-report measure assessing symptoms of schizotypy. The SPQ has been used in both normative and clinical samples and has much theoretical and empirical support. A three-factor structure of the SPQ, derived on the basis of work in schizophrenia, consisting of Cognitive-Perceptual, Interpersonal, and Disorganized factors, has been well replicated. The present study aimed to (i) validate this three-factor structure in the Chinese version of the SPQ in a sample of individuals of Chinese ethnicity, and (ii) test for invariance across sex.
  
  
  METHODS
  A total of 209 (99 males) undergraduate university students (Mage  = 19.5, SD = 1.6) were administered the SPQ.
  
  
  RESULTS
  Confirmatory factor analysis indicated a better fit between the data and the three-factor model compared with a one-factor model. Multigroup confirmatory factor analysis also found strong measurement invariance across sex.
  
  
  CONCLUSIONS
  The current results add to a growing body of literature evidencing cross-cultural validity of the SPQ and its invariance across sex. Research and clinical implications of the current results are discussed.
