Developmental Delay: When and How to Screen

Area of Science:

• Pediatrics
• Developmental Psychology
• Public Health

Background:

• Approximately 15% of US children experience developmental delays, but less than 20% receive early intervention before age three.
• Barriers to screening and referral hinder timely access to crucial developmental support services.
• Early intervention is proven effective for high-risk children, improving cognitive and academic performance.

Purpose of the Study:

• To highlight the importance of early detection of developmental delays in children.
• To emphasize the role of primary care in implementing developmental screening.
• To review effective screening tools for pediatric developmental assessment.

Main Methods:

• Discusses the integration of validated screening tools into primary care workflows.
• Recommends regular, repeated screening intervals alongside physician surveillance during well-child visits.
• Compares parent-completed versus directly administered screening tools, favoring parent-completed options for efficiency.

Main Results:

• Validated screening tools can be effectively integrated into primary care settings.
• Parent-completed tools like the Ages and Stages Questionnaire and Parents' Evaluation of Developmental Status are efficient and well-evaluated.
• Early intervention is associated with significant improvements in cognitive and academic outcomes.

Conclusions:

• Family physicians should be knowledgeable about available developmental screening tools, their strengths, and limitations.
• Routine screening and timely referral are essential for children with suspected developmental delays.
• Proactive screening in primary care can significantly improve early intervention rates and child development outcomes.
