Résumé :	Background Although autism spectrum disorder (ASD) is increasing around the world, the interest in developing and validating screening instruments in the Arab countries is still in the initial stage. The current study examined psychometric properties of a unidimensional 14-item screening tool that was developed in Qatar to identify ASD infants and toddlers between the ages of 15 and 33 months. Methods Rash analysis was carried out on a sample of 22,307 records of children who were screened by this instrument. The analysis was done for two age groups: 15–24 months, and 25–33 months, and across two administration modes: paper and pencil, and electronic modes. Results The findings of the current study showed mixed results: some scale properties were good, whereas others were poor. Almost all 12 items retained for the final form showed acceptable values for the infit and outfit statistics and fulfilled the assumptions of local independence and unidimensionality for the two groups of children and across the two administration modes. However, reliability and separation for persons and items, and targeting of items to children along the autistic trait were not acceptable. Moreover, low sensitivity and specificity asserted that ASD was not accurately identified in children. Conclusions The findings of the current study identified weaknesses in three areas: the small number of items used to measure the autistic trait, the small number of response categories within each item, and the low sensitivity and specificity of the instrument. Suggestions were provided to address these weaknesses.
