Titre : Childhood inhibition predicts adolescent social anxiety: Findings from a longitudinal twin study Type de document : Texte imprimé et/ou numérique Auteurs : H. Hill GOLDSMITH, Auteur ; Emily C. HILTON, Auteur ; Jenny M. PHAN, Auteur ; Katherine L. SARKISIAN, Auteur ; Ian C. CARROLL, Auteur ; Kathryn LEMERY-CHALFANT, Auteur ; Elizabeth M. PLANALP, Auteur Article en page(s) : p.1666-1685 Langues : Anglais (eng) Mots-clés : behavior inhibition genetics parenting social anxiety twins Index. décimale : PER Périodiques Résumé : An enduring issue in the study of mental health is identifying developmental processes that explain how childhood characteristics progress to maladaptive forms. We examine the role that behavioral inhibition (BI) has on social anxiety (SA) during adolescence in 868 families of twins assessed at ages 8, 13, and 15 years. Multimodal assessments of BI and SA were completed at each phase, with additional measures (e.g., parenting stress) for parents and twins. Analyses were conducted in several steps: first, we used a cross-lagged panel model to demonstrate bidirectional paths between BI and SA; second a biometric Cholesky decomposition showed that both genetic and environmental influences on childhood BI also affect adolescent SA; next, multilevel phenotypic models tested moderation effects between BI and SA. We tested seven potential moderators of the BI to SA prediction in individual models and included only those that emerged as significant in a final conditional model examining predictors of SA. Though several main effects emerged as significant, only parenting stress had a significant interaction with BI to predict SA, highlighting the importance of environmental moderators in models examining temperamental effects on later psychological symptoms. This comprehensive assessment continues to build the prototype for such developmental psychopathology models.

[article]
Titre : Childhood temperament: Passive gene–environment correlation, gene–environment interaction, and the hidden importance of the family environment Type de document : Texte imprimé et/ou numérique Auteurs : Kathryn LEMERY-CHALFANT, Auteur ; Karen KAO, Auteur ; Gregory SWANN, Auteur ; H. Hill GOLDSMITH, Auteur Article en page(s) : p.51-63 Index. décimale : PER Périodiques Résumé : Biological parents pass on genotypes to their children, as well as provide home environments that correlate with their genotypes; thus, the association between the home environment and children's temperament can be genetically (i.e., passive gene–environment correlation) or environmentally mediated. Furthermore, family environments may suppress or facilitate the heritability of children's temperament (i.e., gene–environment interaction). The sample comprised 807 twin pairs (mean age = 7.93 years) from the longitudinal Wisconsin Twin Project. Important passive gene–environment correlations emerged, such that home environments were less chaotic for children with high effortful control, and this association was genetically mediated. Children with high extraversion/surgency experienced more chaotic home environments, and this correlation was also genetically mediated. In addition, heritability of children's temperament was moderated by home environments, such that effortful control and extraversion/surgency were more heritable in chaotic homes, and negative affectivity was more heritable under crowded or unsafe home conditions. Modeling multiple types of gene–environment interplay uncovered the complex role of genetic factors and the hidden importance of the family environment for children's temperament and development more generally.

[article]
Titre : Children's responses to daily social stressors: relations with parenting, children's effortful control, and adjustment Type de document : Texte imprimé et/ou numérique Auteurs : Carlos VALIENTE, Auteur ; Kathryn LEMERY-CHALFANT, Auteur Année de publication : 2009 Article en page(s) : p.707-717 Langues : Anglais (eng) Mots-clés : Parenting effortful-control coping adjustment Index. décimale : PER Périodiques Résumé : Background: We examined children's coping and involuntary stress responses as mediators of the relations between parenting or children's effortful control (EC) and adjustment.
Method: Two hundred and forty primarily Mexican American 7- to 12-year-old children reported on their EC, coping, involuntary stress responses, and problem behaviors. Teachers reported on children's academic competence. Parents reported on their reactions to children's negative emotions and on children's EC, problem behaviors, and academic competence.
Results: There were significant zero-order relations between parents' affective responses to children's negative emotions, children's EC, engagement coping, disengagement coping, involuntary stress responses, and adjustment. Consistent evidence emerged that children's engagement coping and involuntary stress-responses mediate the relations between parenting or EC and adjustment.
Conclusions: Results highlight the utility of assessing stress responses in a multidimensional manner and have implications for intervention programs.En ligne : http://dx.doi.org/10.1111/j.1469-7610.2008.02019.x Permalink : https://www.cra-rhone-alpes.org/cid/opac_css/index.php?lvl=notice_display&id=755

[article]
Titre : Children's sleep, impulsivity, and anger: shared genetic etiology and implications for developmental psychopathology Type de document : Texte imprimé et/ou numérique Auteurs : Samantha A. MIADICH, Auteur ; Amanda M. SHREWSBURY, Auteur ; Leah D. DOANE, Auteur ; Mary C. DAVIS, Auteur ; Sierra CLIFFORD, Auteur ; Kathryn LEMERY-CHALFANT, Auteur Article en page(s) : p.1070-1079 Langues : Anglais (eng) Mots-clés : Sleep anger impulsivity Index. décimale : PER Périodiques Résumé : BACKGROUND: Prior research has established links between poor sleep and problems in emotion regulation. Impulsivity and anger/frustration are core features of child psychopathology. Further, sleep problems are commonly associated with psychopathology. This study examined shared and unique genetic and environmental influences on sleep, impulsivity, and anger/frustration in the middle childhood period with potential ramifications for psychopathology. METHODS: Families (29.9% monozygotic, 38.6% same-sex dizygotic, 31.5% opposite-sex dizygotic) from a longitudinal twin study participated (N = 613 twins). Twins (M(age) = 8.37, SD = 0.66; 49% female; 58% non-Latinx European American, 30% Latinx) wore actigraph watches for seven days to assess sleep. Primary caregivers (95.3% mothers) completed standardized questionnaires to assess twins' temperament (impulsivity, anger/frustration). RESULTS: Univariate ACE twin structural equation models indicated strong genetic influences (76%) on impulsivity, whereas the largest proportion of variance in anger/frustration was attributed to the shared environment (56%). Bivariate model fitting indicated that sleep-impulsivity and sleep-anger/frustration associations in children are genetic; thus, a mutual underlying genetic factor likely contributes to the commonality in these associations. CONCLUSIONS: Given evidence that sleep problems, impulsivity, and anger/frustration are mechanisms associated with psychopathology, our findings suggest a genetic commonality and the need to focus on shared and unique risk factors when understanding etiology. Early intervention and prevention efforts should target both sleep problems and high levels of impulsivity and anger/frustration in children, which may have implications for later psychopathology.

This pattern can be the result of heterotypic continuity, in which different behaviors emerge over time based on an underlying shared etiology. In particular, there is largely a shared genetic etiology underlying externalizing and substance use behaviors. We examined whether polygenic risk for alcohol use disorder predicted (1) externalizing behavior in early adolescence and alcohol use in adolescence in the Early Steps Multisite sample and (2) externalizing behavior in adolescence and alcohol use in early adulthood in the Project Alliance 1 (PAL1) sample. We examined associations separately for African Americans and European Americans. When examining European Americans in the Early Steps sample, greater polygenic risk was associated with externalizing behavior in early adolescence. In European Americans in PAL1, we found greater polygenic risk was associated with alcohol use in early adulthood. Effects were largely absent in African Americans in both samples. Results imply that genetic predisposition for alcohol use disorder may increase risk for externalizing and alcohol use as these behaviors emerge developmentally.
