Abstract

<p>The present study investigated the reliability and fitness of the Chinese translated “Autism-Spectrum Quotient (AQ)” via the frameworks of the theoretically-derived five-factorial model (Baron-Cohen et al., 2001) and the statistically-derived five-factorial model (Lau & Gau et al., 2013). The AQ was administered to 355 native Chinese in the general population, and the model fitness indices for the overall confirmatory factor analyses indicated that neither model exhibited appropriate fitness with the data of the present study. Thus, we calculated the contribution scores from each of the AQ sub-categories by confirmatory factor analyses and extracted five items from each category of the AQ50 (a total of 50 items) developed by Baron-Cohen et al. (2001). This resulted in an AQ consisting of 25 question items (AQ25), which we proposed as the new Chinese AQ. The data distribution of the AQ25 was close to normal distribution. Cronbach's reliability coefficient (N=355, α=.78) and the test-retest reliability coefficient (N=15, r=.85) were both high. The Chinese version AQ25, consisting of half the question items of Baron-Cohen et al.'s AQ50 English version (2001), can measure the autistic spectrum from a Chinese general population and should be effective for clinical purposes.</p>
