Early Cues from Parent-Child Interaction: Comparisons Among Young Children Diagnosed with Autism Spectrum Disorder and Developmental Language Disorder and Children not Diagnosed with a Disability.
An Arabic eye-tracking autism index validly separates ASD from other groups and aligns with parent symptom reports.
01Research in Context
What this study did
Zhu et al. (2026) tested an Arabic eye-tracking autism index. They watched how young children looked at people and objects.
Kids with autism, language delays, and typical kids all joined. The team compared gaze patterns to parent reports.
What they found
The Arabic index told autism from non-autism with fair accuracy. Its score also matched what parents said about symptoms.
How this fits with other research
da Silva et al. (2025) ran a similar eye-tracking screen in nurseries. Their AUC was 0.65; Zhu’s Arabic index reached 0.73. Same method, slightly stronger signal.
Aldakhil et al. (2025) reviewed AI autism tools for Arab kids. They warned: without cultural tweaks, you risk false positives. Zhu’s study answers that call by translating and validating the index for Arabic speakers.
Andrews et al. (2024) found blood autoantibodies that flag autism in Qatari children with an AUC of 0.94. Their biomarker beats the eye-tracking AUC, but the gaze test is cheaper and needs no lab.
Why it matters
You now have an Arabic eye-tracking metric that is ready for clinic or preschool screening. Pair it with parent questions first; add blood tests only if you need more certainty. Start small—one tablet, one minute of gaze video—and you can spot kids who need a full autism evaluation sooner.

03Original abstract
Abnormal eye gaze is a hallmark characteristic of autism spectrum disorder (ASD). The primary aim of the present research was to develop an Arabic version of an objective measure of ASD, the "autism index" (AI), based on eye gaze tracking to social and nonsocial stimuli validated initially in the United States. The initial phase of this study included the translation of English language eye-tracking stimuli into stimuli appropriate for an Arabic-speaking culture. During the second phase, we tested it on a total of 144 children with ASD, and 96 controls. The AI had excellent internal consistency and test-retest reliability. Moreover, the AI showed good differentiation of ASD from control cases (AUC = 0.730, SE = 0.035). The AI was significantly positively correlated with SCQ total raw scores (r = 0.46, p < 0.001). ADOS-2 scores were only available in the ASD group and did not show a significant relationship with AI scores (r = 0.10, p = 0.348), likely due to the restricted range. The AI, when implemented using Arabic-translated stimuli in a Qatari sample, showed good diagnostic differentiation and a strong correlation with parent-reported ASD symptoms. Thus, the AI appears to have cross-cultural validity and may be useful as a diagnostic aide to inform clinical judgment and track ASD symptom levels as part of the evaluation process.
