Genetic and environmental influences on the developmental trajectory of callous-unemotional traits from childhood to adolescence / Yusuke TAKAHASHI in Journal of Child Psychology and Psychiatry, 62-4 (April 2021)

Titre : Genetic and environmental influences on the developmental trajectory of callous-unemotional traits from childhood to adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Yusuke TAKAHASHI, Auteur ; Christopher R. PEASE, Auteur ; Jean-Baptiste PINGAULT, Auteur ; Essi VIDING, Auteur Article en page(s) : p.414-423 Langues : Anglais (eng) Mots-clés : Callous-unemotional traits genetic and environmental aetiology latent growth model trajectory twin study Index. décimale : PER Périodiques Résumé : BACKGROUND: This study examined the genetic and environmental influences underlying baseline level and developmental course of callous-unemotional (CU) traits across childhood and adolescence. METHODS: The data on 8,958 twin pairs (3,108 MZ twin pairs and 5,850 DZ twin pairs) from the Twins Early Development Study were analysed. CU traits were assessed at ages 7, 9, 12 and 16 by mothers and analysed using a biometric latent growth model. RESULTS: Individual differences in the baseline level of CU traits were highly heritable (76.5%), while the heritability of the developmental course of CU traits was moderate (43.6%). The genetic influences on baseline level and developmental course of CU traits were mostly nonoverlapping. Nonshared environment made a modest contribution to the baseline level of CU traits (21.7%). Nonshared environmental influences on the developmental course of CU traits were moderate (43.2%), with nearly half of them being the same as those influencing the baseline level and just over half being specific. Shared environmental effects did not contribute to systematic change across childhood and adolescence but were rather age-specific. CONCLUSIONS: Our findings demonstrate that rather than only being conceptualized as factors of stability, genes also play a dynamic role in explaining systematic change in CU traits. Genetic effects for the initial risk and subsequent development of CU traits are not the same. In addition to genetic factors, nonshared environmental influences play an important role in explaining why some children will increase or maintain their CU traits over time, whereas other will desist. New genetic and environmental influences with age suggest that repeated, age-tailored interventions may be required throughout development to make a lasting difference in the presentation of CU traits and associated outcomes.

[article]
Titre : Parental internalizing disorder and the developmental trajectory of infant self-regulation: The moderating role of positive parental behaviors Type de document : Texte imprimé et/ou numérique Auteurs : Xiaoning SUN, Auteur ; John R. SEELEY, Auteur ; Nicholas B. ALLEN, Auteur Article en page(s) : p.1-17 Langues : Anglais (eng) Mots-clés : latent growth model parental internalizing disorder positive parental behaviors self-regulation Index. décimale : PER Périodiques Résumé : Child self-regulation (SR), a key indicator for later optimal developmental outcomes, may be compromised in the presence of parental mental disorders, especially those characterized by affective dysregulation. However, positive parental behaviors have been shown to buffer against such negative effects, especially during infancy when SR shows great plasticity to environmental inputs. The current study investigated the effect of maternal and paternal lifetime and current internalizing disorders on the developmental trajectory of infant SR from 3 to 24 months, and the potential moderating role of positive parental behaviors. A latent growth model revealed that SR increased overall from 3 to 24 months. Mothers? positive parental behaviors demonstrated significant moderation effects, such that maternal lifetime internalizing disorder was associated with higher SR intercept only among those with low levels of positive parental behavior. Mothers? lifetime internalizing disorder was also associated with a lower linear slope in SR development with a moderate effect size. Fathers? current internalizing disorder was significantly associated with a higher intercept and lower linear slope of the SR trajectory. The current study expands the infant SR literature by describing its early developmental trajectory as well as early risk and protective factors within the parent?infant environment, taking into consideration developmental inputs from both parents.
