Summary
Early autism screening at 18 months using the CHAT tool identified 19 children. Further surveillance identified more cases, highlighting the importance of developmental assessments for early autism recognition.
Area of Science:
- Developmental Pediatrics
- Child Psychology
- Early Childhood Education
Background:
- Determining optimal autism screening timing requires extensive empirical study.
- Early identification of autism spectrum disorder (ASD) is crucial for timely intervention.
- The study evaluated an 18-month screening tool for autism detection.
Discussion:
- Practitioners found the 18-month check useful for assessing prelanguage and prosocial skills.
- Training with the Checklist for Autism in Toddlers (CHAT) enhanced practitioner skills and confidence.
- The CHAT tool may reduce the age of autism recognition and referral for assessment.
Key Insights:
- 19 of 50 children with autism were identified at the 18-month screen.
- Additional cases were identified at 42 months and 7 years through ongoing surveillance.
- The study highlights the challenges and benefits of early autism screening protocols.
Outlook:
- Further research is needed to establish definitive screening guidelines for autism.
- The developed screening instrument shows promise in improving early detection rates.
- Enhanced practitioner training can positively impact the early identification of developmental disorders.
