- Assessment of neurocognitive development during the first 1000 days after birth is important, particularly in children in low- and middle-income countries (LMIC).
- Various instruments are used for these assessments, mostly based on a defined set of tasks for the child to perform.
- Tasks typically are scored as a set of ordered categories.
- Development score (D-score) may integrate data collected using different scales and across different populations.
- The purpose of this work was:
- To evaluate the assumptions underlying the D-score using data from an LMIC population, and
- To assess whether the D-score can be used for between-population comparisons.
