Childhood temperament: Passive gene–environment correlation, gene–environment interaction, and the hidden importance of the family environment / Kathryn LEMERY-CHALFANT in Development and Psychopathology, 25-1 (February 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-1 (February 2013) . - p.51-63 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.

Effect of housing relocation and neighborhood environment on adolescent mental and behavioral health / Gayle R. BYCK in Journal of Child Psychology and Psychiatry, 56-11 (November 2015)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 56-11 (November 2015) . - p.1185-1193 Titre : Effect of housing relocation and neighborhood environment on adolescent mental and behavioral health Type de document : Texte imprimé et/ou numérique Auteurs : Gayle R. BYCK, Auteur ; John BOLLAND, Auteur ; Danielle DICK, Auteur ; Gregory SWANN, Auteur ; David HENRY, Auteur ; Brian MUSTANSKI, Auteur Article en page(s) : p.1185-1193 Langues : Anglais (eng) Mots-clés : Adolescent  housing relocation  sexual risk-taking  mental health  substance abuse Index. décimale : PER Périodiques Résumé : Background This study examined whether relocating from a high-poverty neighborhood to a lower poverty neighborhood as part of a federal housing relocation program (HOPE VI; Housing Opportunities for People Everywhere) had effects on adolescent mental and behavioral health compared to adolescents consistently living in lower poverty neighborhoods. Methods Sociodemographic, risk behavior, and neighborhood data were collected from 592 low-income, primarily African-American adolescents and their primary caregivers. Structured psychiatric interviews were conducted with adolescents. Prerelocation neighborhood, demographic, and risk behavior data were also included. Hierarchical Linear Modeling (HLM) was used to test associations between neighborhood variables and risk outcomes. HLM was used to test whether the effect of neighborhood relocation and neighborhood characteristics might explain differences in sexual risk taking, substance use, and mental health outcomes. Results Adolescents who relocated of HOPE VI neighborhoods (n = 158) fared worse than control group participants (n = 429) on most self-reported mental health outcomes. The addition of subjective neighborhood measures generally did not substantively change these results. Conclusions Our findings suggest that moving from a high-poverty neighborhood to a somewhat lower poverty neighborhood is not associated with better mental health and risk behavior outcomes in adolescents. The continued effects of having grown up in a high-poverty neighborhood, the small improvements in their new neighborhoods, the comparatively short length of time they lived in their new neighborhood, and/or the stress of moving appears to worsen most of the mental health outcomes of HOPE VI compared to control group participants who consistently lived in the lower poverty neighborhoods.

Interactions among catechol-O-methyltransferase genotype, parenting, and sex predict children's internalizing symptoms and inhibitory control: Evidence for differential susceptibility / Michael J. SULIK in Development and Psychopathology, 27-3 (August 2015)  

Public ISBD [article]  inDevelopment and Psychopathology > 27-3 (August 2015) . - p.709-723 Titre : Interactions among catechol-O-methyltransferase genotype, parenting, and sex predict children's internalizing symptoms and inhibitory control: Evidence for differential susceptibility Type de document : Texte imprimé et/ou numérique Auteurs : Michael J.

STOVER, Auteur ; Brian C. VERRELLI, Auteur Article en page(s) : p.709-723 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We used sex, observed parenting quality at 18 months, and three variants of the catechol-O-methyltransferase gene (Val158Met [rs4680], intron1 [rs737865], and 3?-untranslated region [rs165599]) to predict mothers' reports of inhibitory and attentional control (assessed at 42, 54, 72, and 84 months) and internalizing symptoms (assessed at 24, 30, 42, 48, and 54 months) in a sample of 146 children (79 male). Although the pattern for all three variants was very similar, Val158Met explained more variance in both outcomes than did intron1, the 3?-untranslated region, or a haplotype that combined all three catechol-O-methyltransferase variants. In separate models, there were significant three-way interactions among each of the variants, parenting, and sex, predicting the intercepts of inhibitory control and internalizing symptoms. Results suggested that Val158Met indexes plasticity, although this effect was moderated by sex. Parenting was positively associated with inhibitory control for methionine–methionine boys and for valine–valine/valine–methionine girls, and was negatively associated with internalizing symptoms for methionine–methionine boys. Using the “regions of significance” technique, genetic differences in inhibitory control were found for children exposed to high-quality parenting, whereas genetic differences in internalizing were found for children exposed to low-quality parenting. These findings provide evidence in support of testing for differential susceptibility across multiple outcomes.
