Objective: Autism is characterized by difficulties in three separate areas involving impairments in social abilities and communication, and repetitive or stereotyped behaviors and interests. Several studies have reported elevated rates of traits related to autism symptoms in first degree relatives called broad autism phenotype. The aim of the study was to evaluate the reliability and psychometric features of the Turkish version of the Autism-Spectrum Quotient (AQ-TR), that was developed by Baron-Cohen and his colleagues and which is a self-administered questionnaire designed to measure the degree to which an adult with normal intelligence has traits associated with autism. Methods: The AQ-TR was administered to 406 university students (58% female, 42% male). To show the reliability of the Turkish version of the AQ (ASQ-TR) Cronbach’s alpha values and test-retest was evaluated on university students. Factor analysis was used to test the construct validity of the scale. Results: Cronbach’s alpha value for the scale was 0.64. Test-retest reliability of the scale was satisfactory (0.72). Male students scored higher in total score (p=0.003) and social skills, communication and imagination subscales. Principal component analysis supported a three factorial structure. Discussion: These results suggest that the ASSQ-TR is a reliable instrument and also the construct validity was shown by factor analysis. The scale was successful on showing the male-female discrepancy which is notified about other cultures. It is necessary to sup-port the validity of the scale by HFA/AS cases participation.
