چکیده
Introduction and Objective: Since their development the Wisconsin Schizotypy Scales have been extensively used to assess schizotypy in clinical and nonclinical samples. The purpose of this study was to examine the psychometric properties of the short forms of the Wisconsin Schizotypy Scales (SWSS) in an Iranian population.
Research Methodology: This research was a correlational design. Three hundred and twelve participants from universities students along with thirty-four schizophrenic patient, and fifty theirs first degree relatives were included in this study. Participants answered to Persian version of SWSS, Short form Oxford-Liverpool Inventory of Feelings and Experiences (SO-LIFE) Questionnaire and Coleridge’s STA scale.
Findings: The results showed internal consistency in terms of Cronbach's α, and test–retest reliability. The results of the two methods showed a good reliability for the shortened WSS. Concurrent validity was tested by comparing with SO-LIFE and STA which showed acceptable relationship. Differential validity was tested by comparing SWSS scores between schizophrenic patients, theirs first degree relatives and normal people which was acceptable.
Conclusion: Moreover, the factor structure of Persian version of SWSS showed two factor solutions, and resembles that seen in previous related studies, providing further cross-cultural empirical evidence of the two factorial structures of the WSS. The present results provide the further demonstration of the validity of the shortened WSS and support their use in the study of schizotypy particularly among Iranian population.
