Psychometric properties of the Persian version of the Autism-Spectrum Quotient (AQ-19) with Iranian university students.

Studies suggest that autistic traits are widespread among the general population and, in this regard, the short form of the Autism-Spectrum Quotient (AQ), the AQ-28, was developed to measure autistic traits. The present study examines the factor structure, internal consistency, and convergent validity of the Persian version of the AQ-28 with 691 Iranian university students (Mage = 28.67, SD = 8.57, 57.3% women) who were recruited online and completed the AQ-28 and Symptom Checklist (SCL-25) measures. Confirmatory factor analysis results yielded a four-factor model, which was internally consistent and demonstrated hypothesized correlations with the external correlates of interest (e.g., anxiety, depression, and phobia). Results support the Persian version of the AQ with 19 items (AQ-19) as a measure with sound psychometrics to be used in studies with Iranian university students.
