Insights

Three screening tools for autism spectrum disorder (ASD) demonstrated high accuracy in children aged 16–30 months. The M-CHAT-R/F, RBSK-ASQ, and TABC showed excellent reliability and validity for early ASD detection.

Area of Science:

  • Developmental Pediatrics
  • Child Psychology
  • Screening Tools

Background:

  • Early detection of autism spectrum disorder (ASD) is crucial for timely intervention.
  • Validated screening tools are essential for identifying at-risk children in primary care settings.

Purpose of the Study:

  • To evaluate the diagnostic accuracy of the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F), the RBSK-ASQ, and the Trivandrum Autism Screening Chart (TABC) for ASD screening.
  • To assess the psychometric properties of these tools in Hindi-speaking children aged 16 to 30 months.

Main Methods:

  • A cross-sectional study involving children aged 16–30 months recruited from a pediatrics department.
  • Exclusion criteria included pre-existing neurodevelopmental disorders, disabilities, severe medical conditions, and maternal inability to understand Hindi.
  • The M-CHAT-R/F, RBSK-ASQ, and TABC were translated into Hindi, piloted, and administered alongside the Developmental Profile (DP-3). A comprehensive expert assessment served as the reference standard.

Main Results:

  • The M-CHAT-R/F demonstrated a sensitivity of 95.2% and specificity of 94.4%.
  • The RBSK-ASQ showed 100% sensitivity and 93.9% specificity.
  • The TABC achieved 100% sensitivity and 94.4% specificity, with high convergent validity (Spearman's rho = 0.98) and excellent test-retest and inter-rater reliability (ICC = 1.00) for all tools.

Conclusions:

  • The M-CHAT-R/F, RBSK-ASQ, and TABC are accurate and reliable tools for screening ASD in Hindi-speaking children aged 16–30 months.
  • These tools possess acceptable psychometric properties, supporting their use in early ASD detection.
  • High validity and reliability indicate their potential for effective implementation in clinical settings.

Autism Spectrum Disorder

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.
