- Abstract
Autism is a neurodevelopmental condition, characterized by altered social communication and repetitive behavior. Typically diagnosed in early childhood, screening and diagnosis at a later age can be challenging, particularly in girls who exhibit a wider range of behaviors and characteristics. This study aimed to examine the Childhood Autism Spectrum Test--Hebrew version in a clinically referred Israeli sample, and to identify items that best discriminate between autistic and non-autistic boys and girls. Parents of 211 autistic (retrospectively reviewed) and 192 non-autistic children, aged 4-12 years, completed the Childhood Autism Spectrum Test--Hebrew version. Results indicated good discriminatory power, with an area under the curve of 0.93. A cutoff of 9 offered optimal sensitivity of 0.93 and specificity of 0.82. The addition of a more focused sex-specific analysis using items that best discriminated autistic from non-autistic boys and girls significantly improved the overall identification rate of autism, particularly in girls. The Childhood Autism Spectrum Test--Hebrew version was positively correlated with the Autism Diagnostic Interview--Revised but not with Autism Diagnostic Observation Schedule-2. Findings underscore the importance of considering sex differences in autism screening and the potential value of sex-specific screening. Future research should focus on replicating these findings in a larger, diverse, prospective study.
