Background: The aim of this study was to investigate the construct validity of the diagnostic test, the Comprehensive Developmental Inventory for Infants and Toddlers (CDIIT). Methods: A total of 1085 children in four age groups (infant, 1‐year‐old, 2‐year‐old, preschool age) were enrolled. The Developmental Quotient of each subdomain of the five CDIIT subtests (Cognition, Language, Motor, Social, and Self‐help) was used as the basic unit for factor analysis with the iterative principle factor method and promax rotation. Results: The two‐factor solution in two younger age groups and 2‐ or 3‐factor solutions in the 2‐year‐old and preschool groups provided superior factor structure in terms of interpretability and compatibility with existing child development theories. Conclusion: Although five constructs were proposed in the original manual of CDIIT, two to three constructs were revealed in this empirical study.
