Common genetic and nonshared environmental factors contribute to the association between socioemotional dispositions and the externalizing factor in children / Jeanette TAYLOR in Journal of Child Psychology and Psychiatry, 54-1 (January 2013)
[article]
Titre : Common genetic and nonshared environmental factors contribute to the association between socioemotional dispositions and the externalizing factor in children Type de document : Texte imprimé et/ou numérique Auteurs : Jeanette TAYLOR, Auteur ; Nicholas P. ALLAN, Auteur ; Amy J. MIKOLAJEWSKI, Auteur ; Sara A. HART, Auteur Article en page(s) : 67-76 Langues : Anglais (eng) Mots-clés : Externalizing genetic temperament dispositions; Index. décimale : PER Périodiques Résumé : Background: Childhood behavioral disorders including conduct disorder (CD), oppositional defiant disorder (ODD), and attention-deficit/hyperactivity disorder (ADHD) often co-occur. Prior twin research shows that common sets of genetic and environmental factors are associated with these various disorders and they form a latent factor called Externalizing. The developmental propensity model posits that CD develops in part from socioemotional dispositions of Prosociality, Negative Emotionality, and Daring; and recent research has supported the expected genetic and environmental associations between these dispositions and CD. This study examined the developmental propensity model in relation to the broader Externalizing factor that represents the covariance among behavior disorders in children. Methods: Parents of 686 six- to twelve-year-old twin pairs rated them on symptoms of CD, ADHD, and ODD using the disruptive behavior disorder scale and on Prosociality, Negative Emotionality, and Daring using the Child and Adolescent Dispositions Scale. A latent factor multivariate Cholesky model was used with each disposition latent factor comprised of respective questionnaire items and the Externalizing factor comprised of symptom dimensions of CD, ADHD inattention, ADHD hyperactivity/impulsivity, and ODD. Results: Results supported the hypothesis that the socioemotional dispositions and the Externalizing factor have genetic factors in common, but there was not a single genetic factor associated with all of the constructs. As expected, nonshared environment factors were shared by the dispositions and Externalizing factor but, again, no single nonshared environmental factor was common to all constructs. A shared environmental factor was associated with both Negative Emotionality and Externalizing. Conclusions: The developmental propensity model was supported and appears to extend to the broader externalizing spectrum of childhood disorders. Socioemotional dispositions of prosociality, negative emotionality, and (to a lesser extent) daring may contribute to the covariation among behavioral disorders and perhaps to their comorbid expression through common sets of primarily genetic but also environmental factors.

Titre : Oppositional defiant disorder dimensions: genetic influences and risk for later psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : Amy J. MIKOLAJEWSKI, Auteur ; Jeanette TAYLOR, Auteur ; William G. IACONO, Auteur Article en page(s) : p.702-710 Langues : Anglais (eng) Mots-clés : Oppositionality symptom dimensions genetic environmental longitudinal Index. décimale : PER Périodiques Résumé : Background This study was undertaken to determine how well two oppositional defiant disorder (ODD) dimensions (irritable and headstrong/hurtful) assessed in childhood predict late adolescent psychopathology and the degree to which these outcomes can be attributed to genetic influences shared with ODD dimensions. Methods Psychopathology was assessed via diagnostic interviews of 1,225 twin pairs at ages 11 and 17. Results Consistent with hypotheses, the irritable dimension uniquely predicted overall internalizing problems, whereas the headstrong/hurtful dimension uniquely predicted substance use disorder symptoms. Both dimensions were predictive of antisocial behavior and overall externalizing problems. The expected relationships between the irritable dimension and specific internalizing disorders were not found. Twin modeling showed that the irritable and headstrong/hurtful dimensions were related to late adolescent psychopathology symptoms through common genetic influences. Conclusions Symptoms of ODD in childhood pose a significant risk for various mental health outcomes in late adolescence. Further, common genetic influences underlie the covariance between irritable symptoms in childhood and overall internalizing problems in late adolescence, whereas headstrong/hurtful symptoms share genetic influences with substance use disorder symptoms. Antisocial behavior and overall externalizing share common genetic influences with both the irritable and headstrong/hurtful dimensions.
