Validation of the autism behavior checklist in Egyptian children with autism spectrum disorder

Abstract

This study was designed to validate the Arabic version of the Autism Behavior Checklist (ABC) for the Egyptian population. A total of 500 mothers of children aged 4-14 years, of whom 150 had a diagnosis of ASD, 100 with intellectual disability, and 250 typically developing children completed the ABC. The factor analysis showed that 48 of 57 ABC items yielded a five-dimensional factor structure. The ABC-Arabic version indicated acceptable internal consistency (α = 0.85) and test - retest reliability (0.82). Also, the ABC exhibited good concurrent validity and discriminative validity. A cutoff score of 58 obtained a sensitivity of 94.7% and a specificity of 92.14% for detecting children with ASD. Our findings support the use of the ABC as a valid screening measure for ASD cases, and it may promote the use of the ABC for clinical and research purposes among Arabic-speaking communities.
