1. Objectifs


Intentions :
« This study aimed to investigate the genetic and environmental etiology of the early developmental stability in disregard for rules. » (p. 198)

2. Méthode


Échantillon/Matériau :
« Participants were twins from the ongoing longitudinal Quebec Newborn Twin Study (QNTS). [...] A total of 597 twin pairs had valid disregard for rules scores for at least one twin on one or more of these four assessment times (1100 children at 20 months, 1039 at 32 months, 880 at 50 months, and 877 at 64 months). » (p. 193-194)

3. Résumé


« [T]his study does fill some important gaps in research on the socialization difficulties inherent to DBD [disruptive behavior disorder]. This is the first genetically informative study to focus on DBD symptoms with repeated measures during early childhood, and to investigate etiological factors underlying continuity and change with both a variance-covariance and a latent growth curve approach, thus providing a more complete view of developmental processes. It demonstrated that genetic factors accounted for individual differences in initial levels of disregard for rules, and for their continuity throughout early childhood. Consequently, to prevent chronic disregard for rules, interventions should take an intergenerational approach and target families with parental history of DBD. This would allow interventions to start very early, such as during pregnancy (Olds et al. 2007). Future studies should investigate which environmental factors may protect from genetic risk, in order to identify optimal intervention targets. » (p. 199)
