3. Résumé

«This non-exhaustive review of some of the most important scientific contributions of QNTS [Quebec Newborn Twin Study] illustrates the potential of this database to elucidate the gene-environment processes underlying (1) the early bio-social determinants of various cognitive, behavioral, and social-emotional components of developmental health across childhood, as well as (2) their role in later social-emotional adjustment, school and health outcomes. Hopefully, this work will also lay the foundation for further interdisciplinary and international collaborations around QNTS on these issues.» (p. 68) «The QNTS also entails extended and detailed multi-level assessments of proximal (e.g., parenting behaviors) and distal (e.g., family income) features of the child’s environment across development. Parenting behaviors were assessed yearly, starting at 5 months, through mother and father self-reports of parental warmth, self-efficacy and impact, overprotection, and hostile-reactive behavior.» (p. 65-66)
