Autism Spectrum Disorder

1.3K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Area of Science:

  • Developmental Psychology
  • Pediatric Psychiatry
  • Behavioral Science

Background:

  • Early detection of Autism Spectrum Disorder (ASD) is crucial for timely intervention.
  • Existing screening tools often require specialized knowledge or are costly.
  • There is a need for accessible, low-cost observational tools for ASD symptom detection.

Purpose of the Study:

  • To introduce and validate the OERA (Observational Emotional Regulation Assessment) as a novel screening tool for ASD.
  • To assess the reliability, validity, and diagnostic accuracy of the OERA in young children.
  • To establish an effective and user-friendly method for identifying children with ASD.

Main Methods:

  • The OERA was administered to a sample of 99 children aged 3-10 years.
  • Participants included 76 children diagnosed with ASD and 23 neurotypical children (11 with intellectual disability).
  • Confirmatory factor analysis was used to evaluate the psychometric properties of the OERA, including interrater agreement, reliability, and factor structure.

Main Results:

  • The OERA demonstrated high interrater agreement and reliability, loading onto a single latent trait.
  • Confirmatory factor analysis indicated an excellent model fit.
  • A cutoff score of five or higher on the OERA achieved high sensitivity (92.75%) and specificity (90.91%) for ASD identification.

Conclusions:

  • The OERA is a brief, stable, and low-cost standardized observational screening tool.
  • It effectively identifies children with ASD without requiring extensive prior knowledge of the disorder.
  • The OERA shows promise as a valuable instrument for early ASD detection in clinical and research settings.
