Titre : The interplay of polygenic plasticity and adrenocortical activity as sources of variability in pathways among family adversity, youth emotional reactivity, and psychological problems Type de document : Texte imprimé et/ou numérique Auteurs : Patrick T. DAVIES, Auteur ; Dante CICCHETTI, Auteur ; Morgan J. THOMPSON, Auteur ; Sonnette M. BASCOE, Auteur ; E. Mark CUMMINGS, Auteur Article en page(s) : p.587-603 Langues : Anglais (eng) Mots-clés : cortisol differential susceptibility family adversity youth emotional reactivity youth psychopathology molecular genetics Index. décimale : PER Périodiques Résumé : This study examined the interplay between a polygenic composite and cortisol activity as moderators of the mediational pathway among family adversity, youth negative emotional reactivity to family conflict, and their psychological problems. The longitudinal design contained three annual measurement occasions with 279 adolescents (Mean age = 13.0 years) and their parents. Latent difference score analyses indicated that observational ratings of adversity in interparental and parent-child interactions at Wave 1 predicted increases in a multimethod, multi-informant assessment of youth negative emotional reactivity to family conflict from Waves 1 to 2. Changes in youth negative emotional reactivity, in turn, predicted increases in a multi-informant (i.e., parents, adolescent, and teacher) assessment of psychological problems from Waves 1 to 3. Consistent with differential susceptibility theory, the association between family adversity and negative emotional reactivity was stronger for adolescents who carried more sensitivity alleles in a polygenic composite consisting of 5-HTTLPR, DRD4 VNTR, and BDNF polymorphisms. Analyses of adolescent cortisol in the period surrounding a family disagreement task at Wave 1 revealed that overall cortisol output, rather than cortisol reactivity, served as an endophenotype of the polygenic composite. Overall cortisol output was specifically associated with polygenic plasticity and moderated the association between family adversity and youth negative emotional reactivity in the same for better or for worse manner as the genetic composite. Finally, moderator-mediated-moderation analyses indicated that the moderating role of the polygenic plasticity composite was mediated by the moderating role of adolescent cortisol output in the association between family adversity and their emotional reactivity.

Furthermore, they may reduce exposure to family adversity for some children. The aim of this study was to determine whether intensity of exposure to child-care services prior to age 5 years has a beneficial effect on disruptive behavior problems during adolescence, and whether the effect is more pronounced for children from low socioeconomic families. METHODS: N = 1,588 participants from the Quebec Longitudinal Study of Child Development were assessed 14 times from 5 months to 17 years. Intensity of child-care exposure was measured from 5 months to 5 years of age. Main outcomes were self-reported physical aggression and opposition from age 12 to 17 years. Family socioeconomic status (SES) was measured at 5 months. Factors explaining differences in child-care use were controlled using propensity score weights (PSW). RESULTS: Children exposed to moderate-intensity child-care services (part-time child-care services before 1(1/2) years and full time afterward) reported lower levels of physical aggression (d = -.11, p = .056) and opposition (d = -.14, p = .029) during adolescence compared to children exposed to low-intensity child-care services. A significant child care by SES interaction (p = .017) for physical aggression indicated that the moderate-intensity child-care effect was specific to children from low SES families (d = -.36, p = .002). No interaction with socioeconomic status was found for opposition. CONCLUSIONS: Moderate-intensity child-care services from infancy to school entry may prevent disruptive behavior during adolescence, especially for disadvantaged children.

Titre : Why does children?s temperamental exuberance increase their vulnerability to externalizing symptoms? A process-oriented approach Type de document : Texte imprimé et/ou numérique Auteurs : Patrick T. DAVIES, Auteur ; Vanessa T. CAO, Auteur ; Meera D. PATEL, Auteur ; Melissa L. STURGE-APPLE, Auteur Article en page(s) : p.429-442 Langues : Anglais (eng) Mots-clés : child externalizing symptoms child responses to family stressors exuberant temperament family adversity risk mechanisms Index. décimale : PER Périodiques Résumé : This study examined children?s exposure to family adversity, hostile reactivity to parental conflict, and negative family representations as mediators of the prospective relation between their temperamental exuberance and externalizing symptoms. Participants included 243 preschool children (Mage = 4.60 years; 56% girls) and parents (48% Black; 16% Latinx) in a multi-method and multi-informant study with three annual measurement occasions. Structural equation model results specifically supported children?s hostile reactivity to parental conflict and negative family representations as mediators. Exuberance predicted residualized increases in children?s hostile reactivity and negative family representations over a 1-year period. In turn, children?s hostile reactivity and negative family representations predicted their greater externalizing symptoms 1 year later after controlling for prior externalizing symptoms. Results are discussed in the context of their relation and refinement of temperamental models of developmental psychopathology.
