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.

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. WIDAMAN, Auteur ; Michael PLUESS, Auteur ; Celia M. T. GREENWOOD, Auteur ; Ashley WAZANA, Auteur Article en page(s) : p.73-83 Langues : Anglais (eng) Mots-clés : diathesis-stress differential-susceptibility gene-by-environment interaction regions of significance vantage sensitivity Index. décimale : PER Périodiques Résumé : Currently, two main approaches exist to distinguish differential susceptibility from diathesis-stress and vantage sensitivity in Genotype x Environment interaction (G x E) research: regions of significance (RoS) and competitive-confirmatory approaches. 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.

Titre : General psychopathology, internalising and externalising in children and functional outcomes in late adolescence Type de document : Texte imprimé et/ou numérique Auteurs : H.

EVANS, Auteur Article en page(s) : p.1183-1190 Langues : Anglais (eng) Mots-clés : Avon Longitudinal Study of Parents and Children Childhood psychopathology Generation Rotterdam Maternal Adversity Vulnerability and Neurodevelopment developmental pathways Index. décimale : PER Périodiques Résumé : BACKGROUND: Internalising and externalising problems commonly co-occur in childhood. Yet, few developmental models describing the structure of child psychopathology appropriately account for this comorbidity. We evaluate a model of childhood psychopathology that separates the unique and shared contribution of individual psychological symptoms into specific internalising, externalising and general psychopathology factors and assess how these general and specific factors predict long-term outcomes concerning criminal behaviour, academic achievement and affective symptoms in three independent cohorts. METHODS: Data were drawn from independent birth cohorts (Avon Longitudinal Study of Parents and Children (ALSPAC), N = 11,612; Generation R, N = 7,946; Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN), N = 408). Child psychopathology was assessed between 4 and 8 years using a range of diagnostic and questionnaire-based measures, and multiple informants. First, structural equation models were used to assess the fit of hypothesised models of shared and unique components of psychopathology in all cohorts. Once the model was chosen, linear/logistic regressions were used to investigate whether these factors were associated with important outcomes such as criminal behaviour, academic achievement and well-being from late adolescence/early adulthood. RESULTS: The model that included specific factors for internalising/externalising and a general psychopathology factor capturing variance shared between symptoms regardless of their classification fits well for all of the cohorts. As hypothesised, general psychopathology factor scores were predictive of all outcomes of later functioning, while specific internalising factor scores predicted later internalising outcomes. Specific externalising factor scores, capturing variance not shared by any other psychological symptoms, were not predictive of later outcomes. CONCLUSIONS: Early symptoms of psychopathology carry information that is syndrome-specific as well as indicative of general vulnerability and the informant reporting on the child. The 'general psychopathology factor' might be more relevant for long-term outcomes than specific symptoms. These findings emphasise the importance of considering the co-occurrence of common internalising and externalising problems in childhood when considering long-term impact.
