Behavior problems in sexually abused preschoolers over a 1-year period: The mediating role of attachment representations / Florence CHAREST in Development and Psychopathology, 31-2 (May 2019)  

Public ISBD [article]  inDevelopment and Psychopathology > 31-2 (May 2019) . - p.471-481 Titre : Behavior problems in sexually abused preschoolers over a 1-year period: The mediating role of attachment representations Type de document : texte imprimé Auteurs : Florence CHAREST, Auteur ; Martine HÉBERT, Auteur ; Annie BERNIER, Auteur ; Rachel LANGEVIN, Auteur ; Raphaele MILJKOVITCH, Auteur Article en page(s) : p.471-481 Langues : Anglais (eng) Mots-clés : attachment behavior problems child sexual abuse mediation preschoolers Index. décimale : PER Périodiques Résumé : According to the developmental psychopathology framework, adverse childhood experiences, including child sexual abuse (CSA), may alter the course of normal development in children. Attachment security has been identified as a protective factor against psychopathology and may thus play a critical role in predicting victims’ adaptation. The main objective of the present study was to investigate the mediating effect of attachment representations in the relation between CSA and behavior problems over a 1-year period. The sample consisted of 391 children (251 sexually abused) aged 3.5 to 6 years. The Attachment Story Completion Task and the Child Behavior Checklist were used. Disorganized attachment partially mediated the relation between CSA and children's internalizing and externalizing behavior problems 1 year following the initial assessment. This mediation effect was not found for ambivalent nor secure attachment dimensions. Child gender was found to moderate the association between CSA and disorganization, with larger effects of CSA among boys. These findings underscore the importance of considering attachment representations in treatment programs for preschool victims. Evidence-based practice focusing on trauma could be combined with an attachment-based intervention targeting the parent–child relationship. Moreover, interventions should be gender sensitive, as CSA appears to affect boys and girls differently.

Deciphering the mediating role of childhood maltreatment in the association between genetic risk and developmental trajectories of school-age reactive and proactive aggression / Isabelle OUELLET-MORIN in Development and Psychopathology, 38-2 (May 2026)  

Public ISBD [article]  inDevelopment and Psychopathology > 38-2 (May 2026) . - p.852-865 Titre : Deciphering the mediating role of childhood maltreatment in the association between genetic risk and developmental trajectories of school-age reactive and proactive aggression Type de document : texte imprimé Auteurs : Isabelle OUELLET-MORIN, Auteur ; Marie-Claude GEOFFROY, Auteur ; Pascal LOUIS, Auteur ; Ivan VORONIN, Auteur ; Geneviève MORNEAU-VAILLANCOURT, Auteur ; Rachel LANGEVIN, Auteur ; Delphine COLLIN-VÉZINA, Auteur ; Charles-Édouard GIGUERE, Auteur ; Mélanie BOULIANE, Auteur ; Amélie PETITCLERC, Auteur ; Mara BRENDGEN, Auteur ; Frank VITARO, Auteur ; Richard Ernest TREMBLAY, Auteur ; Michel BOIVIN, Auteur Article en page(s) : p.852-865 Langues : Anglais (eng) Mots-clés : Childhood maltreatment  genetics  gene–environmental correlation (rGE)  longitudinal studies: proactive and reactive aggression Index. décimale : PER Périodiques Résumé : Background:Childhood maltreatment is a robust predictor of aggression. Research indicates that both maltreatment experiences and aggression are moderately heritable. It has been hypothesized that gene–environment correlation may be at play, whereby genetic predispositions to aggression in parents and children may be confounded with family environments conducive to its expression. Building on this framework, we tested whether maltreatment mediates the association between a polygenic score for aggression (PGSAGG) and school-age aggression, and whether this varied for reactive and proactive aggression.Methods:The sample comprised 721 participants (44.9% males; 99.0% White) with prospective assessments of maltreatment from 5 months to 12 years (10 assessments;1998–2010), and teachers-reported aggression from ages 6 to 13 (6 assessments; 2004–2011). The PGSAGG was derived using a Bayesian estimation method (PRS-CS).Results:PGSAGG was associated with most aggression measures across specific ages and trajectories. Maltreatment experiences partially mediated the association between PGSAGG and the Childhood-Limited trajectory of reactive – but not proactive – aggression.Conclusion:Children with higher genetic propensities for aggression were more likely to experience maltreatment, which partly explained the association between PGSAGG and a Childhood-Limited trajectory of reactive aggression during elementary school. This finding reinforces the possibility of confounding influences between genetic liability for aggression and maltreatment experiences.

Prediction of depressive symptoms in young adults by polygenic score and childhood maltreatment: Results from a population-based birth cohort / Marie-Claude GEOFFROY ; Rachel LANGEVIN ; Léa C.

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.
