What this trial studies

This observational study aims to assess the accuracy of general pediatricians in diagnosing autism spectrum disorder (ASD) compared to a multidisciplinary expert team. The study will involve 20 pediatricians from Ontario, Canada, who will evaluate 200 children referred for possible ASD. The pediatricians will make their assessments without informing the families, while an expert team will conduct their evaluations independently. The study will also explore the effectiveness of a new virtual diagnostic tool, the Autism Assessment for Preschoolers with Language Element Sequence (AAPLES).

Who should consider this trial

Good fit: Ideal candidates are children under 5 years 6 months who have been referred to a participating pediatrician with concerns related to development or behavior.

Not a fit: Patients who have already received a diagnosis of ASD will not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the accuracy of autism diagnoses in community settings, leading to earlier interventions for children.

How similar studies have performed: While there are few studies on the accuracy of general pediatricians in diagnosing ASD, this approach is relatively novel and aims to fill a significant gap in existing research.
