MCADAMS, Auteur Article en page(s) : p.1875-1888 Langues : Anglais (eng) Mots-clés : Cognition  internalising disorder  behavioural genetics  longitudinal studies Index. décimale : PER Périodiques Résumé : Background Emotional problems co-occur with difficulties in verbal and nonverbal cognitive ability, yet the pathways underlying their association remain poorly understood: It is unclear whether effects may be causal, and to what extent they may run from cognition to emotion, or vice versa. Methods Our preregistered analyses included 5,124 twin pairs from the Twins Early Development Study (TEDS). At ages 7, 9 and 12, emotional problems were assessed through the strengths and difficulties questionnaire, and cognition was assessed using task-based measures. Cross-lagged models examined the influence of cognition and subdomains of verbal and nonverbal abilities on emotional problems and vice versa, across development. Genetic cross-lagged models examined the effect of cognition on emotional problems and vice versa, after controlling for shared genetic and environmental influence. Results Cross-lagged paths in both directions were observed between cognitive ability and emotional problems (from ?0.11 to ?0.05). Cross-lagged associations that persisted after accounting for common genetic and environmental influences were between nonverbal ability and emotional problems. Higher emotional problems at age 7 predicted lower nonverbal ability at age 9, with 22% of the phenotypic association remaining. This, in turn, predicted greater emotional problems at age 12, with 13% of the association remaining. Conclusions Genetic and environmental factors accounted for a large proportion of the cross-lagged associations. Emotional problems in early childhood could result in a cascade effect, leading to lower nonverbal cognition in middle childhood, which increases the risk of emotional problems in late childhood. These findings highlight the importance of age- and domain-specific interventions.

How are children's perceptions of the home environment associated with a general psychopathology factor across childhood? / Jack K. NEJAND in Journal of Child Psychology and Psychiatry, 67-2 (February 2026)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 67-2 (February 2026) . - p.266-281 Titre : How are children's perceptions of the home environment associated with a general psychopathology factor across childhood? Type de document : texte imprimé Auteurs : Jack K. NEJAND, Auteur ; Margherita MALANCHINI, Auteur ; Ivan VORONIN, Auteur ; Thalia C. ELEY, Auteur ; Kaili RIMFELD, Auteur Article en page(s) : p.266-281 Langues : Anglais (eng) Mots-clés : General factor of psychopathology  p-factor  childhood psychopathology  twin analysis  home environment  cross-lag model Index. décimale : PER Périodiques Résumé : Background Comorbidity and heterogeneity in psychiatric disorders may stem from a general psychopathology (p) factor influenced by both genetic and environmental factors. Although the relative contributions of these influences on psychopathology are established, the longitudinal associations between the p-factor and specific environmental exposures and the aetiology of these associations across development are not well understood. Here, we examine whether twin-rated home environment contributes to changes in the p-factor over time or, conversely, whether the p-factor influences twin-rated home environment, reflecting potential evocative gene?environment processes. Methods Data were obtained from the Twins Early Development Study (TEDS). Cross-lagged panel analyses were conducted separately to ascertain the direction of associations between parent-rated p, twin-rated p, and twin-rated home environment (chaos at home and parental discipline) at ages 9, 12, and 16 (N?=?6,213). Biometric autoregressive cross-lagged twin models were used to assess the aetiology of these associations, and MZ differences analyses were used to control for familial effects. Results Both parent-rated and twin-rated p-factor and twin-rated home environment were stable over time, although the twin-rated p-factor (r?=?.44 [0.42, 0.46]?.40 [0.37, 0.41]) was more variable than the parent-rated p-factor (r?=?.72 [0.71, 0.74]?.63 [0.61, 0.64]). Twin-rated home environment was more variable than p-factor in all cross-lagged models (phenotypic and MZ differences). Small, significant bidirectional associations were found between the p-factor and twin-rated home environment, with stronger cross-lagged paths from the p-factor to the twin-rated home environment than vice versa. These longitudinal associations persisted over time, though attenuated for parent-rated p-factor. Genetic analyses revealed that bidirectional cross-lagged paths were largely explained by shared environmental factors, with a smaller proportion explained by genetic factors. This pattern of results was confirmed in MZ difference analyses. Conclusions Our findings suggest a dynamic and bidirectional relationship between p-factor and twin-rated home environment across development, predominantly influenced by shared environmental factors. Changes in one can affect the other, highlighting the complexity of psychopathology's environmental influences. This underscores the need for further investigation into gene?environment interplay to inform prevention and intervention strategies for psychopathology.

Therefore, we investigate whether genetic predisposition for depression (i.e., polygenic score for depression, PGSDEP) modifies the association between maltreatment and depressive symptoms, while accounting for different types of maltreatment and whether it was evaluated through prospective and retrospective reports. The sample included 541-617 participants from the Quebec Longitudinal Study of Child Development with information on maltreatment, including threat, deprivation, assessed prospectively (5 months-17 years) and retrospectively (reported at 23 years), PGSDEP and self-reported depressive symptoms (20-23 years). Using hierarchical linear regressions, we found that retrospective, but not prospective indicators of maltreatment (threat/deprivation/cumulative) were associated with later depressive symptoms, above and beyond the PGSDEP. Our findings also show the presence of gene-environment interactions, whereby the association between maltreatment (retrospective cumulative maltreatment/threat, prospective deprivation) and depression was strengthened among youth with higher PGSDEP scores. Consistent with the Diathesis-Stress hypothesis, our findings suggest that a genetic predisposition for depression may exacerbate the putative impact of maltreatment on later depressive symptoms, especially when maltreatment is retrospective. Understanding the gene-environment interplay emerging in the context of maltreatment has the potential to guide prevention efforts.
