Abstract

Schizotypy is the latent personality reflecting the liability to schizophrenia. The Multidimensional Schizotypy Scale (MSS) is a newly developed questionnaire to measure the levels of schizotypy. The Chinese version of MSS has been developed and previous findings supported its structure validity. The present study aimed to examine the construct validity of the Chinese version of the MSS by correlating it with the Schizotypal Personality Questionnaire (SPQ). A total of 1359 university students completed the MSS and the SPQ online. The results of 1027 valid participants demonstrated that all MSS dimensions showed good internal consistency. The MSS positive dimension is strongly correlated with SPQ cognitive-perceptual factor, the MSS negative dimension with the SPQ interpersonal factor, and the MSS disorganized dimension with the SPQ disorganized factor. Taken together, our study provides evidence for construct validity of the Chinese version of the MSS.
