Does the persistence of development delay predict receipt of early intervention services?

Area of Science:

• Child Development
• Public Health
• Pediatrics

Background:

• Early intervention services (EI) are crucial for addressing developmental delays in infants and toddlers.
• Understanding factors influencing EI access is vital for equitable service provision.

Purpose of the Study:

• To investigate how the persistence and nature of developmental delays impact the utilization of early intervention services.

Main Methods:

• Analysis of the Early Childhood Longitudinal Study, Birth cohort (ECLS-B) data.
• Developmental delay assessed at 9 and 24 months, categorized by severity (none, mild, moderate/severe).
• Logistic regression models used to determine the likelihood of receiving EI at 24 months based on developmental change.

Main Results:

• EI utilization varied by delay severity, type, and temporal pattern.
• Children with persistent cognitive delays were more likely to receive EI compared to those with improving or emerging delays.
• Children experiencing motor skill regression from normal to moderate/severe were more likely to receive EI than those with persistent motor delays.

Conclusions:

• Children with dynamic developmental delays generally have reduced access to EI compared to those with persistent delays, with notable exceptions for significant motor skill regression.
• Findings underscore the need for enhanced developmental surveillance, improved referral pathways, and better understanding of EI service utilization.
