3. Résumé


The QNTS documents «individual differences in the cognitive, behavioral, social-emotional aspects of developmental health across childhood, their early genetic and environmental determinants, as well as their putative role in later social-emotional adjustment, school and health outcomes. A population-based sample of >660 families of twins were initially enrolled in QNTS, and then assessed longitudinally at regular intervals. The QNTS is part of a larger research initiative that also involves the Québec Longitudinal Study of Child Development (QLSCD), an ongoing longitudinal follow-up of a representative sample of >2000 children born as singletons in 1998 in the province of Québec, Canada. The QNTS and the QLSCD are companion studies sharing many features (measures and time of assessments), including an extensive and detailed set of evaluations in the early years, thus providing together a unique window into the role of early childhood in development.» (p. 475) The authors also mention that «[t]his work is laying the foundation for further interdisciplinary and international collaborations around QNTS on these issues […].» (p. 479)
