Adolescent age moderates genetic and environmental influences on parent–adolescent positivity and negativity: Implications for genotype–environment correlation / Kristine MARCEAU in Development and Psychopathology, 28-1 (February 2016)

GANIBAN, Auteur ; David REISS, Auteur Article en page(s) : p.149-166 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We examined how genotype–environment correlation processes differ as a function of adolescent age. We tested whether adolescent age moderates genetic and environmental influences on positivity and negativity in mother–adolescent and father–adolescent relationships using parallel samples of twin parents from the Twin and Offspring Study in Sweden and twin/sibling adolescents from the Nonshared Environment in Adolescent Development Study. We inferred differences in the role of passive and nonpassive genotype–environment correlation based on biometric moderation findings. The findings indicated that nonpassive gene–environment correlation played a stronger role for positivity in mother– and father–adolescent relationships in families with older adolescents than in families with younger adolescents, and that passive gene–environment correlation played a stronger role for positivity in the mother–adolescent relationship in families with younger adolescents than in families with older adolescents. Implications of these findings for the timing and targeting of interventions on family relationships are discussed.

Eye tracking indices of attentional bias in children of depressed mothers: Polygenic influences help to clarify previous mixed findings / Max OWENS in Development and Psychopathology, 28-2 (May 2016)  

Public ISBD [article]  inDevelopment and Psychopathology > 28-2 (May 2016) . - p.385-397 Titre : Eye tracking indices of attentional bias in children of depressed mothers: Polygenic influences help to clarify previous mixed findings Type de document : Texte imprimé et/ou numérique Auteurs : Max OWENS, Auteur ; Ashley J.

GIBB, Auteur Article en page(s) : p.385-397 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Information-processing biases may contribute to the intergenerational transmission of depression. There is growing evidence that children of depressed mothers exhibit attentional biases for sad faces. However, findings are mixed as to whether this bias reflects preferential attention toward, versus attentional avoidance of, sad faces, suggesting the presence of unmeasured moderators. To address these mixed findings, we focused on the potential moderating role of genes associated with hypothalamic–pituitary–adrenal axis reactivity. Participants included children (8–14 years old) of mothers with (n = 81) and without (n = 81) a history of depression. Eye movements were recorded while children passively viewed arrays of angry, happy, sad, and neutral faces. DNA was obtained from buccal cells. Children of depressed mothers exhibited more sustained attention to sad faces than did children of nondepressed mothers. However, it is important that this relation was moderated by children's genotype. Specifically, children of depressed mothers who carried reactive genotypes across the corticotropin-releasing hormone type 1 receptor (CHRH1) TAT haplotype and FK506 binding protein 5 (FKBP5) rs1360780 (but not the solute carrier family C6 member 4 [SLC6A4] of the serotonin transporter linked polymorphic region [5-HTTLPR]) exhibited less sustained attention to sad faces and more sustained attention to happy faces. These findings highlight the role played by specific genetic influences and suggest that previous mixed findings may have been due to genetic heterogeneity across the samples.

Intergenerational transmission of psychopathology: An examination of symptom severity and directionality / Kristine MARCEAU in Development and Psychopathology, 34-5 (December 2022)  

Public ISBD [article]  inDevelopment and Psychopathology > 34-5 (December 2022) . - p.1767-1780 Titre : Intergenerational transmission of psychopathology: An examination of symptom severity and directionality Type de document : Texte imprimé et/ou numérique Auteurs : Kristine MARCEAU, Auteur ; Li YU, Auteur ; Valerie S. KNOPIK, Auteur ; Jody M. GANIBAN, Auteur ; Jenae M. NEIDERHISER, Auteur Article en page(s) : p.1767-1780 Langues : Anglais (eng) Mots-clés : children-of-twins  comorbidity  directionality  externalizing  intergenerational transmission  internalizing  severity Index. décimale : PER Périodiques Résumé : The present study examined the intergenerational transmission of internalizing and externalizing symptom severity, which indexes comorbidity, and symptom directionality, which indicates differentiation toward externalizing versus internalizing problems. Data are from 854 male and female, same-sex adult twin pairs born between 1926 and 1971 (32 “60 years old, M = 44.9 years, SD = 4.9 years) from the Twin and Offspring Study in Sweden and their adolescent offspring (11 “22 years old, M = 15.7 years, SD = 2.4 years, 52% female). Children-of-twins models revealed additive (9%) and dominant (45%) genetic and nonshared environmental (47%) influences on twins’ symptom severity, and additive genetic (39%) and nonshared environmental (61%) influences on twins’ symptom directionality. Both comorbid problems and preponderance of symptoms of a particular “ internalizing versus externalizing “ spectrum were correlated across parent and child generations, although associations were modest especially for directionality (i.e., transmission of specific symptom type). By interpreting findings alongside a recent study of adolescent twins, we demonstrate that the intergenerational transmission of symptom severity and symptom directionality are both unlikely to be attributable to genetic transmission, are both likely to be influenced by direct phenotypic transmission and/or nonpassive rGE, and the intergenerational transmission of symptom severity is also likely to be influenced by passive rGE.

The epigenetics of maternal cigarette smoking during pregnancy and effects on child development / Valerie S. KNOPIK in Development and Psychopathology, 24-4 (November 2012)  

Public ISBD [article]  inDevelopment and Psychopathology > 24-4 (November 2012) . - p.1377-1390 Titre : The epigenetics of maternal cigarette smoking during pregnancy and effects on child development Type de document : Texte imprimé et/ou numérique Auteurs : Valerie S. KNOPIK, Auteur ; Matthew A. MACCANI, Auteur ; Sarah FRANCAZIO, Auteur ; John E. MCGEARY, Auteur Année de publication : 2012 Article en page(s) : p.1377-1390 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : The period of in utero development is one of the most critical windows during which adverse intrauterine conditions and exposures can influence the growth and development of the fetus as well as the child's future postnatal health and behavior. Maternal cigarette smoking during pregnancy remains a relatively common but nonetheless hazardous in utero exposure. Previous studies have associated prenatal smoke exposure with reduced birth weight, poor developmental and psychological outcomes, and increased risk for diseases and behavioral disorders later in life. Researchers are now learning that many of the mechanisms whereby maternal smoke exposure may affect key pathways crucial for proper fetal growth and development are epigenetic in nature. Maternal cigarette smoking during pregnancy has been associated with altered DNA methylation and dysregulated expression of microRNA, but a deeper understanding of the epigenetics of maternal cigarette smoking during pregnancy as well as how these epigenetic changes may affect later health and behavior remain to be elucidated. This article seeks to explore many of the previously described epigenetic alterations associated with maternal cigarette smoking during pregnancy and assess how such changes may have consequences for both fetal growth and development, as well as later child health, behavior, and well-being. We also outline future directions for this new and exciting field of research.
