VERHULST, Auteur ; Henning TIEMEIER, Auteur ; Philip SHAW, Auteur Article en page(s) : p.687-694 Langues : Anglais (eng) Mots-clés : Heritability  peer networks  externalizing  internalizing  preschoolers Index. décimale : PER Périodiques Résumé : Background Peer relationships are important for children's mental health, yet little is known of their etiological underpinnings. Here, we explore the genetic influences on childhood peer network characteristics in three different networks defined by rejection, acceptance, and prosocial behavior. We further examine the impact of early externalizing and internalizing trajectories on these same peer network characteristics. Methods Participants were 1,288 children from the Dutch ‘Generation R’ birth cohort. At age 7, we mapped out children's classroom peer networks for peer rejection, acceptance, and prosocial behavior using mutual peer nominations. In each network, genetic influences were estimated for children's degree centrality, closeness centrality and link reciprocity from DNA using Genome-wide Complex Trait Analysis. Preschool externalizing and internalizing trajectories were computed using parental ratings at ages 1.5, 3, and 5 years. Results Of the three network properties examined, closeness centrality emerged as significantly heritable across all networks. Preschool externalizing problems predicted unfavorable positions within peer rejection networks and having fewer mutual friendships. In contrast, children with preschool-internalizing problems were not actively rejected by their peers, but were less well-connected within their social support network. Conclusions Our finding of significant heritability for closeness centrality should be taken as preliminary evidence that requires replication. Nevertheless, it can orient us to the role of genes in shaping a child's position within peer networks. Additionally, social network perspectives offer rich insights into how early life mental health trajectories impact a child's later functioning within peer networks.

Combined polygenic risk scores of different psychiatric traits predict general and specific psychopathology in childhood / Alexander NEUMANN in Journal of Child Psychology and Psychiatry, 63-6 (June 2022)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 63-6 (June 2022) . - p.636-645 Titre : Combined polygenic risk scores of different psychiatric traits predict general and specific psychopathology in childhood Type de document : Texte imprimé et/ou numérique Auteurs : Alexander NEUMANN, Auteur ; Alexia JOLICOEUR-MARTINEAU, Auteur ; Eszter SZEKELY, Auteur ; Hannah M. SALLIS, Auteur ; Kieran O'DONNEL, Auteur ; Celia M. T. GREENWOOD, Auteur ; Robert LEVITAN, Auteur ; Michael J. MEANEY, Auteur ; Ashley WAZANA, Auteur ; Jonathan P. EVANS, Auteur ; Henning TIEMEIER, Auteur Article en page(s) : p.636-645 Langues : Anglais (eng) Mots-clés : Genetics  comorbidity  externalizing disorder  internalizing disorder  meta-analysis  molecular Index. décimale : PER Périodiques Résumé : BACKGROUND: Polygenic risk scores (PRSs) operationalize genetic propensity toward a particular mental disorder and hold promise as early predictors of psychopathology, but before a PRS can be used clinically, explanatory power must be increased and the specificity for a psychiatric domain established. To enable early detection, it is crucial to study these psychometric properties in childhood. We examined whether PRSs associate more with general or with specific psychopathology in school-aged children. Additionally, we tested whether psychiatric PRSs can be combined into a multi-PRS score for improved performance. METHODS: We computed 16 PRSs based on GWASs of psychiatric phenotypes, but also neuroticism and cognitive ability, in mostly adult populations. Study participants were 9,247 school-aged children from three population-based cohorts of the DREAM-BIG consortium: ALSPAC (UK), The Generation R Study (Netherlands), and MAVAN (Canada). We associated each PRS with general and specific psychopathology factors, derived from a bifactor model based on self-report and parental, teacher, and observer reports. After fitting each PRS in separate models, we also tested a multi-PRS model, in which all PRSs are entered simultaneously as predictors of the general psychopathology factor. RESULTS: Seven PRSs were associated with the general psychopathology factor after multiple testing adjustment, two with specific externalizing and five with specific internalizing psychopathology. PRSs predicted general psychopathology independently of each other, with the exception of depression and depressive symptom PRSs. Most PRSs associated with a specific psychopathology domain, were also associated with general child psychopathology. CONCLUSIONS: The results suggest that PRSs based on current GWASs of psychiatric phenotypes tend to be associated with general psychopathology, or both general and specific psychiatric domains, but not with one specific psychopathology domain only. Furthermore, PRSs can be combined to improve predictive ability. PRS users should therefore be conscious of nonspecificity and consider using multiple PRSs simultaneously, when predicting psychiatric disorders.

Distinguishing differential susceptibility, diathesis-stress, and vantage sensitivity: Beyond the single gene and environment model / Alexia JOLICOEUR-MARTINEAU in Development and Psychopathology, 32-1 (February 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-1 (February 2020) . - p.73-83 Titre : Distinguishing differential susceptibility, diathesis-stress, and vantage sensitivity: Beyond the single gene and environment model Type de document : Texte imprimé et/ou numérique Auteurs : Alexia JOLICOEUR-MARTINEAU, Auteur ; Jay BELSKY, Auteur ; Eszter SZEKELY, Auteur ; Keith F.

Each is limited by its single-gene/single-environment foci given that most phenotypes are the product of multiple interacting genetic and environmental factors. We thus addressed these two concerns in a recently developed R package (LEGIT) for constructing G x E interaction models with latent genetic and environmental scores using alternating optimization. Herein we test, by means of computer simulation, diverse G x E models in the context of both single and multiple genes and environments. Results indicate that the RoS and competitive-confirmatory approaches were highly accurate when the sample size was large, whereas the latter performed better in small samples and for small effect sizes. The competitive-confirmatory approach generally had good accuracy (a) when effect size was moderate and N >/= 500 and (b) when effect size was large and N >/= 250, whereas RoS performed poorly. Computational tools to determine the type of G x E of multiple genes and environments are provided as extensions in our LEGIT R package.

Maternal depressive symptoms and sensitivity are related to young children's facial expression recognition: The Generation R Study / Eszter SZEKELY in Development and Psychopathology, 26-2 (May 2014)

HERBA, Auteur Article en page(s) : p.333-345 Index. décimale : PER Périodiques Résumé : A vast body of literature shows that maternal depression has long-term adverse consequences for children. However, only very few studies have documented the effect of maternal depression on children's ability to process emotional expressions and even fewer incorporated measures of observed maternal sensitivity to further tease apart whether it is the symptoms per se or the associated impact via maternal sensitivity that affects children's developing emotion-processing abilities. In a large community sample of Dutch preschoolers (N = 770), we examined independent and mediated effects of maternal depressive symptoms and sensitivity on children's ability to recognize emotional expressions using a nonverbal and a verbal task paradigm. Maternal depressive symptoms predicted less accurate emotion labeling in children, while maternal sensitivity was associated with more accurate emotion matching, especially for sadness and anger. Maternal sensitivity did not mediate the observed associations between mothers’ depressive symptoms and children's emotion recognition, and effects were similar for boys and girls. Given that maternal depressive symptoms and sensitivity affected nonoverlapping areas of young children's emotion recognition, prevention and intervention efforts should focus on both alleviating maternal depressive symptoms and improving maternal sensitivity at the same time in order to maximize benefit.

The participants were 335 mother-infant dyads from the Maternal Adversity, Vulnerability and Neurodevelopment project. A Confirmatory Bifactor Analysis (CFA) based on self-report measures of prenatal depression and pregnancy-specific anxiety generated a general factor representing overlapping symptoms of prenatal maternal psychopathology and four distinct symptom factors representing pregnancy-specific anxiety, negative affect, anhedonia and somatization. NE was rated by the mother at 18 and 36 months. CFA based on measures of father, mother, child-rated measures and a semistructured interview generated a general internalizing factor representing overlapping symptoms of child internalizing psychopathology accounting for the unique contribution of each informant. Path analyses revealed significant relationships among the general maternal affective psychopathology, the pregnancy- specific anxiety, and the child internalizing factors. Child NE mediated only the relationship between pregnancy-specific anxiety and the child internalizing factors. We highlighted the conditions in which prenatal maternal affective symptoms predicts child internalizing problems emerging early in development, including consideration of different mechanistic pathways for different maternal prenatal symptom presentations and child temperament.
