Developmental screening tools: Bridging early detection and intervention in infant health assessment

Introduction:

The objective of this study was to evaluate the performance and application of standardized developmental screening tools for early detection of delays and disabilities in infants, and to explore their integration within comprehensive pediatric health assessment. We therefore performed a literature review of existing developmental screening instruments and their implementation in diverse healthcare settings.

Materials and Methods:

This comprehensive review analyzes current research on validated screening tools, examining their psychometric properties, theoretical foundations, and challenges faced during implementation across various healthcare environments. Data on sensitivity, specificity, and their association with growth and morbidity outcomes are synthesized.

Results:

Key validated screening tools demonstrate variable performance characteristics: Ages and Stages Questionnaires (sensitivity 70%–90%, specificity 76%–91%), Denver II (sensitivity 56-83%), modified checklist for autism in toddlers revised, with follow-up (sensitivity 85%, specificity 99% with follow-up), and parents’ evaluation of developmental status (sensitivity 74%–79%, specificity 70%–80%). There are strong associations between growth faltering, morbidity burden, and developmental outcomes, supporting the need for integrated surveillance.

Conclusions:

Integrating developmental screening with growth monitoring and morbidity assessment offers a comprehensive pediatric care framework. Universal implementation of validated screening tools at 9, 18, and 30 months, coupled with established referral pathways, can significantly reduce the burden of developmental disabilities and promote optimal infant development.
