Quebec Newborn Twin Study
Initiatives
-
The goals of the Quebec Newborn Twin Study (QNTS) are to document individual differences in the cognitive, behavioral, social-emotional aspects of developmental health across childhood, their early biosocial, i.e., genetic and environmental, determinants, as well as their putative role in later social-emotional adjustment, school and health outcomes.
Objectives:
* To identify the environmental factors that influence the different aspects of children's behaviour.
* To study the evolution over time of biological and social aspects of childhood development.
* To understand the origin of the diffences and similarities that exist between children born at the same time and who share the same milieu.
