Chapter 9 Three studies

This section compares child development between samples from three different studies:

  • SMOCC, a representative sample of Dutch children (9.1)
  • POPS, a cohort of all Dutch preterms in 1983 (9.2)
  • TOGO, a set of medical records from preventive health service in Togo (9.3)
  • A summary of the main findings (9.4)

Each study used the same measurement instrument, the DDI (see Section 4.1). The section compares D-scores between studies.
