Growth charts of human development

---

This article reviews and compares two types of growth charts for tracking human development over age.
Both charts assume the existence of a continuous latent variable, but relate to the observed data in
different ways. The D-score diagram summarizes developmental indicators into a single aggregate score
measuring global development. The relations between the indicators should be consistent with the Rasch
model. If true, the D-score is a measure with interval scale properties, and allows for the calculation
of meaningful differences both within and across age. The stage line diagram describes the natural
development of ordinal indicators. The method models the transition probabilities between successive
stages of the indicator as smoothly varying functions of age. The location of each stage is quantified by the
mid-P-value. Both types of diagrams assist in identifying early and delayed development, as well as finding
differences in tempo. The relevant techniques are illustrated to track global development during infancy
and early childhood (0–2 years) and Tanner pubertal stages (8–21 years). New reference values for both
applications are provided.

Keywords: Bayley scale, Tanner stages, references, D-score diagram, stage line diagram, age continuity, gain score
