TL;DR
The Kidsights Measurement Tool (KMT) is validated as a reliable parent-reported instrument for tracking early childhood development disparities in the U.S.
Contribution
The KMT is the first validated population-level tool for children birth to five years in the U.S., enabling large-scale tracking of developmental disparities.
Findings
The KMT detects disparities in child development linked to parent education, mental health, and child race/ethnicity.
The KMT correlates strongly with gold-standard developmental assessment tools like the Bayley Scale and Woodcock-Johnson.
The KMT shows strong reliability and no measurement noninvariance across groups.
Abstract
Disparities in child development between groups of children arise early and reflect social inequities in early environments, geography, and other factors. To track and address these disparities, valid and reliable tools are needed that can be implemented at-scale and across populations. However, no population-level measures of child development appropriate for children from birth to age five years have been developed and validated in the United States to date. The Kidsights Measurement Tool (KMT) is a parent-report, population-level tool for children birth to age five years intended to track group-level differences in the developmental status across normative aspects of children’s motor, cognitive, language, and social/emotional development. This study reports on validation of KMT as a feasible tool that can be implemented in large-scale surveys to track disparities in early childhood…
