Our objective is to test the possibility that participation in childcare – at the population level – could attenuate the gap in academic readiness and achievement between children with and without a social disadvantage (indexed by low levels of maternal education). Methods:  A cohort of infants born in the Canadian province of Quebec in 1997/1998 was selected through birth registries and followed annually until 7 years of age (n = 1,863). Children receiving formal childcare (i.e., center-based or non-relative out-of-home) were distinguished from those receiving informal childcare (i.e., relative or nanny). Measures from 4 standardized tests that assessed cognitive school readiness (Lollipop Test for School Readiness), receptive vocabulary (Peabody Picture Vocabulary Test Revised), mathematics (Number Knowledge Test), and reading performance (Kaufman Assessment Battery for children) were administered at 6 and 7 years. Results:  Children of mothers with low levels of education showed a consistent pattern of lower scores on academic readiness and achievement tests at 6 and 7 years than those of highly educated mothers, unless they received formal childcare. Specifically, among children of mothers with low levels of education, those who received formal childcare obtained higher school readiness (d = 0.87), receptive vocabulary (d = 0.36), reading(d = 0.48) and math achievement scores (d = 0.38; although not significant at 5%) in comparison with those who were cared for by their parents. Childcare participation was not associated with cognitive outcomes among children of mothers with higher levels of education. Conclusions:  Public investments in early childcare are increasing in many countries with the intention of reducing cognitive inequalities between disadvantaged and advantaged children. Our findings provide further evidence suggesting that formal childcare could represent a preventative means of attenuating effects of disadvantage on children’s early academic trajectory.

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.

Stigma associated with parental depression or cancer: Impact on spouse and offspring's cortisol levels and socioemotional functioning / Sonia J. LUPIEN in Development and Psychopathology, 32-5 (December 2020)

Adding to the stress of caregiving is the stigma often placed against spouses and children of people with mental illness. Contrary to mental illness, many physical disorders such as cancer may be less stigmatized (expect pulmonary cancer). In this study, we measured externalized and internalized stigma, as well as psychological (depressive symptoms and stressful life events) and physiological (basal salivary cortisol levels) markers of stress in 115 spouses and 154 children of parents suffering from major depressive disorder, cancer, or no illness (control group). The results show that spouses and children from families with parental depression present significantly more externalized stigma than spouses and children from families with parental cancer or no illness, although we find no group differences on internalized stigma. The analysis did not show a significant group difference either for spouses or their children on depressive symptomatology, although spouses from the parental depression group reported greater work/family stress. Finally, we found that although for both spouses children the awakening cortisol response was greater on weekdays than on weekend days, salivary cortisol levels did not differ between groups. Bayes factor calculated on the null result for cortisol levels was greater than 100, providing strong evidence for the null hypothesis H0. Altogether, these results suggest an impact of stigma toward mental health disorder on psychological markers of stress but no impact of stigma on physiological markers of stress. We suggest that these results may be due to the characteristics of the families who participated in the present study.
