Novel Approaches for the Measurement of Early Childhood Development

Summary
Written by AI, not yet AICS's view · claude-haiku-4-5-20251001This research develops new methods to measure how infants and toddlers actually engage in their daily activities, rather than relying only on clinical assessments. The study creates two tools: the Infant Toddler Activity Card Sort to document real-world engagement, and uses wearable accelerometers to track movement patterns. The aim is to identify developmental delays earlier so children can access early intervention services during the critical first three years when the brain develops most rapidly. The approach addresses a gap in current measurement tools that fail to capture what children actually do in everyday life.
Key points
- Current evaluation methods measure developmental progress but fail to capture real-world activity and engagement in children's everyday lives
- Motor deficits are often the first measurable sign of developmental dysfunction, but subtle impairment is frequently missed by parents and pediatricians during brief clinical encounters
- Activity card sorts can help caregivers become active participants in their child's healthcare team
- Wearable accelerometry technology can afford early screening for children at risk for motor deficits during their typical day
- Evidence supports using bilateral wrist-worn accelerometers to accurately measure upper extremity motor activity in children

Abstract
Early identification of developmental delay (DD) is essential to providing timely and targeted intervention in the first years of life when the brain is considered to be the most malleable. Current evaluation methods are designed to measure developmental progress but fail to capture the child’s real-world activity and engagement. This thesis aims to describe innovative approaches to improve measurement of what children are doing in their everyday lives. Activity card sorts (ACS) provide a method for individuals to be an active part of their own healthcare team, yet there is none to support caregivers in this vulnerable age group. When DD are identified early, children 0-36 months can be eligible to receive early intervention. Motor deficits are often the first easily measurable sign of dysfunction, but subtle impairment is often missed by parents and pediatricians during brief clinical encounters. Wearable technology has opened up the opportunity for measurement of real-world movement during a child’s typical day and a method to affordably screen children at risk for motor deficits. Evidence suggests that movement measured with bilateral wrist-worn accelerometers can accurately describe upper extremity motor activity in children. The purpose of this dissertation was twofold: (1) Develop and validate the Infant Toddler Activity Card Sort (ITACS) to describe real-world engagement of infants/toddlers and (2) Use accelerometry to describe real-world activity of children with and without disability.
