We conducted secondary analyses of the Québec Longitudinal Study of Child Development data (n = 974). Each adolescent completed items from the Conflict Tactics Scale (at ages 15 and 17 years) to assess psychological, physical, and sexual dating violence victimization and perpetration in the past 12 months. Adolescents' symptoms of depression and general anxiety in the past 12 months were self-reported (at ages 15 and 17 years) using The Mental Health and Social Inadaptation Assessment for Adolescents. There were concurrent associations of adolescents' internalizing symptoms with dating violence victimization and perpetration. Internalizing symptoms at age 15 years were positively associated with dating violence victimization and perpetration 2 years later in both males and females, even after adjusting for baseline characteristics. However, neither dating violence victimization nor perpetration at age 15 years was associated with internalizing symptoms 2 years later. For males and females, internalizing symptoms put adolescents at risk for future dating violence victimization and perpetration. Interventions that target internalizing symptoms may have the potential to decrease subsequent dating violence.

Association between nonmaternal care in the first year of life and children's receptive language skills prior to school entry: the moderating role of socioeconomic status / Marie-Claude GEOFFROY in Journal of Child Psychology and Psychiatry, 48-5 (May 2007)

However, few tested the possibility that NMC may be more or less protective for children with different family backgrounds. This study investigates the role of the family environment, as reflected in the socioeconomic status (SES), in the association between NMC in the first year of life and children's receptive language skills prior to school entry. Method: A representative sample of 2,297 Canadian children aged between 0 and 11 months at their first assessment was followed over 4 years. Receptive language skills were assessed with the Peabody Picture Vocabulary Test Revised (PPVT-R) when the child was 4 to 5 years old. Results: After controlling for selection factors, SES was found to moderate the association between NMC and receptive language skills: Full-time NMC in the first year of life was associated with higher PPVT-R scores among children from low SES families (d = .58), but not among children from adequate SES families. Conclusion: Full-time NMC in infancy may contribute to reducing the cognitive inequalities between children of low and adequate SES.

Associations between developmental trajectories of peer victimization, hair cortisol, and depressive symptoms: a longitudinal study / Isabelle OUELLET-MORIN in Journal of Child Psychology and Psychiatry, 62-1 (January 2021)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 62-1 (January 2021) . - p.19-27 Titre : Associations between developmental trajectories of peer victimization, hair cortisol, and depressive symptoms: a longitudinal study Type de document : Texte imprimé et/ou numérique Auteurs : Isabelle OUELLET-MORIN, Auteur ; Christina CANTAVE, Auteur ; Stéphane PAQUIN, Auteur ; Marie-Claude GEOFFROY, Auteur ; Mara BRENDGEN, Auteur ; Frank VITARO, Auteur ; Richard TREMBLAY, Auteur ; Michel BOIVIN, Auteur ; Sonia LUPIEN, Auteur ; Sylvana M. CÔTÉ, Auteur Article en page(s) : p.19-27 Langues : Anglais (eng) Mots-clés : HPA axis  Peer victimization  depression  hair cortisol  nonlinear models Index. décimale : PER Périodiques Résumé : BACKGROUND: Peer victimization has been associated with long-lasting risks for mental health. Prior research suggests that stress-related systems underlying adaptation to changing environments may be at play. To date, inconsistent findings have been reported for the hypothalamic-pituitary-adrenal (HPA) axis, and its end product cortisol. This study tested whether peer victimization was associated with hair cortisol concentrations (HCC), and whether this association varied according to sex, timing, and changes in exposure. We also examined whether peer victimization differentially predicted depressive symptoms according to HCC. METHODS: The sample comprised 556 adolescents (42.0%; 231 males) who provided hair for cortisol measurement at 17 years of age. Peer victimization was reported at seven occasions between the ages of 6 and 15 years. RESULTS: Peer victimization was nonlinearly associated with HCC for boys only, whereas changes in peer victimization were related to HCC for boys and girls. Peer victimization predicted more depressive symptoms for all participants, except those with lower HCC. CONCLUSIONS: Our findings provide further support for persistent dysregulation of the HPA axis following exposure to chronic adversity, of which the expression may change according to sex and the severity of victimization.

Closing the gap in academic readiness and achievement: the role of early childcare / Marie-Claude GEOFFROY in Journal of Child Psychology and Psychiatry, 51-12 (December 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-12 (December 2010) . - p.1359-1367 Titre : Closing the gap in academic readiness and achievement: the role of early childcare Type de document : Texte imprimé et/ou numérique Auteurs : Marie-Claude GEOFFROY, Auteur ; Sylvana M. CÔTÉ, Auteur ; Charles-Édouard GIGUERE, Auteur ; Ginette DIONNE, Auteur ; Philip David ZELAZO, Auteur ; Richard E. TREMBLAY, Auteur ; Michel BOIVIN, Auteur ; Jean R. SEGUIN, Auteur Année de publication : 2010 Article en page(s) : p.1359-1367 Langues : Anglais (eng) Mots-clés : Cognition  prevention  social class  day care Index. décimale : PER Périodiques Résumé : Background:  Socially disadvantaged children with academic difficulties at school entry are at increased risk for poor health and psychosocial outcomes. 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.

Contribution of genes and environment to the longitudinal association between childhood impulsive-aggression and suicidality in adolescence / Massimiliano ORRI in Journal of Child Psychology and Psychiatry, 61-6 (June 2020)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 61-6 (June 2020) . - p.711-720 Titre : Contribution of genes and environment to the longitudinal association between childhood impulsive-aggression and suicidality in adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Massimiliano ORRI, Auteur ; Marie-Claude GEOFFROY, Auteur ; Gustavo TURECKI, Auteur ; Bei FENG, Auteur ; Mara BRENDGEN, Auteur ; Frank VITARO, Auteur ; Ginette DIONNE, Auteur ; Stéphane PAQUIN, Auteur ; Cédric GALERA, Auteur ; Johanne RENAUD, Auteur ; Richard E.

CÔTÉ, Auteur ; Michel BOIVIN, Auteur Article en page(s) : p.711-720 Langues : Anglais (eng) Mots-clés : Suicide attempt  behavioral genetics  impulsive-aggression  longitudinal  suicidal ideation  twin study Index. décimale : PER Périodiques Résumé : BACKGROUND: Population-based and family studies showed that impulsive-aggression predicts suicidality; however, the underlying etiological nature of this association is poorly understood. The objective was to determine the contribution of genes and environment to the association between childhood impulsive-aggression and serious suicidal ideation/attempt in young adulthood. METHODS: N = 862 twins (435 families) from the Quebec Newborn Twin Study were followed up from birth to 20 years. Repeated measures of teacher-assessed impulsive-aggression were modeled using a genetically informed latent growth model including intercept and slope parameters reflecting individual differences in the baseline level (age 6 years) and in the change (increase/decrease) of impulsive-aggression during childhood (6 to 12 years), respectively. Lifetime suicidality (serious suicidal ideation/attempt) was self-reported at 20 years. Associations of impulsive-aggression intercept and slope with suicidality were decomposed into additive genetic (A) and unique environmental (E) components. RESULTS: Additive genetic factors accounted for an important part of individual differences in impulsive-aggression intercept (A = 90%, E = 10%) and slope (A = 65%, E = 35%). Genetic (50%) and unique environmental (50%) factors equally contributed to suicidality. We found that 38% of the genetic factors accounting for suicidality were shared with those underlying impulsive-aggression slope, whereas 40% of the environmental factors accounting for suicidality were shared with those associated with impulsive-aggression intercept. The genetic correlation between impulsive-aggression slope and suicidality was 0.60, p = .027. CONCLUSIONS: Genetic and unique environmental factors underlying suicidality significantly overlap with those underlying childhood impulsive-aggression. Future studies should identify putative genetic and environmental factors to inform prevention.
