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 : Longitudinal investigation of anxiety sensitivity growth trajectories and relations with anxiety and depression symptoms in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Nicholas P. ALLAN, Auteur ; Julia W. FELTON, Auteur ; Carl W. LEJUEZ, Auteur ; Laura MACPHERSON, Auteur ; Norman B. SCHMIDT, Auteur Article en page(s) : p.459-469 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Anxiety sensitivity (AS), the belief that anxious arousal is harmful, is a malleable risk factor that has been implicated in anxiety and depression symptoms in adolescents. Although there is some evidence that adolescents possess distinct developmental trajectories, few studies have explored this topic. This study examined the developmental trajectory of AS in 248 adolescents (M age = 11.0 years, SD = 0.82; 56% male) across 6 years, beginning when children were age 11. This study also examined the influence of AS trajectories on anxiety and depression at age 16. Finally, this study examined the utility of AS classes in identifying anxiety and depression growth. Three AS classes were found, described by normative-stable, high-stable, and high-unstable trajectories. Adolescents in the high-stable and the high-unstable AS classes had higher levels of anxiety and depression at age 16 than did adolescents in the normative-stable AS class. In addition, the anxiety and depression trajectories fit by AS class mirrored the AS class trajectories. These findings suggest three AS trajectories can be identified in adolescents. These trajectories are discussed in relation to a developmental perspective of AS.
