Validation of the International Guide for Monitoring Child Development demonstrates good sensitivity and specificity in four diverse countries.

Aim: It is of critical importance to have internationally constructed tools to address early childhood development. The aim of this second phase of a two-phase study was to examine the sensitivity and specificity of the Guide for Monitoring Child Development (GMCD) in identifying developmental delay in four diverse countries.

Methods: The first phase of this 2011-2015 back-to-back study included 4949 children up to 42 months of age from primary healthcare centres in Argentina, India, South Africa and Turkey.

Similarities and differences in child development from birth to age 3 years by sex and across four countries: a cross-sectional, observational study.

Background: Knowledge about typical development is of fundamental importance for understanding and promoting child health and development. We aimed to ascertain when healthy children in four culturally and linguistically different countries attain developmental milestones and to identify similarities and differences across sexes and countries.

Methods: In this cross-sectional, observational study, we recruited children aged 0-42 months and their caregivers between March 3, 2011, and May 18, 2015, at 22 health clinics in Argentina, India, South Africa, and Turkey.
