The genetic etiology of inhibitory control and behavior problems at 24 months of age / Jeffrey R. GAGNE in Journal of Child Psychology and Psychiatry, 52-11 (November 2011)
[article]
Titre : The genetic etiology of inhibitory control and behavior problems at 24 months of age Type de document : Texte imprimé et/ou numérique Auteurs : Jeffrey R. GAGNE, Auteur ; Kimberly J. SAUDINO, Auteur ; Philip ASHERSON, Auteur Année de publication : 2011 Article en page(s) : p.1155-1163 Langues : Anglais (eng) Mots-clés : Inhibitory control behavior problems early childhood twins genetics Index. décimale : PER Périodiques Résumé : Background: To investigate links between inhibitory control (IC) and behavior problems in early childhood, as well as genetic and environmental covariances between these two constructs.
Methods: Parent and laboratory ratings of IC and parent ratings of externalizing and attention deficit hyperactivity disorder behaviors were administered at 24 months of age on a sample of 291 same-sex twin pairs (131 monozygotic, 160 dizygotic).
Results: There were significant phenotypic associations between both IC assessments and the two areas of behavioral maladjustment (correlations ranged from −.13 to −.57). Multivariate analyses revealed that phenotypic covariance between IC and behavior problems could be substantially explained by common genetic influences (genetic correlations ranged from −.30 to −.74). Parent ratings of IC showed higher phenotypic and genetic correlations with behavior problems than lab ratings of IC.
Conclusions: This study is the first to examine the etiology of the covariance between IC and related behavioral difficulties in toddlerhood. Findings suggest that low levels of IC can be considered a genetic risk factor for the development of early emerging behavior problems.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2011.02420.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=145
