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 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 J. 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.

Chronic bullying victimization across school transitions: The role of genetic and environmental influences / Lucy BOWES in Development and Psychopathology, 25-2 (May 2013)  

Public ISBD [article]  inDevelopment and Psychopathology > 25-2 (May 2013) . - p.333-346 Titre : Chronic bullying victimization across school transitions: The role of genetic and environmental influences Type de document : texte imprimé Auteurs : Lucy BOWES, Auteur ; Barbara MAUGHAN, Auteur ; Harriet A.

MOFFITT, Auteur ; Louise ARSENEAULT, Auteur Article en page(s) : p.333-346 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : We investigated the antecedents and consequences of chronic victimization by bullies across a school transition using a genetically sensitive longitudinal design. Data were from the Environmental Risk Longitudinal Twin Study (E-Risk), an epidemiological cohort of 2,232 children. We used mothers' and children's reports of bullying victimization during primary school and early secondary school. Children who experienced frequent victimization at both time points were classed as “chronic victims” and were found to have an increased risk for mental health problems and academic difficulties compared to children who were bullied only in primary school, children bullied for the first time in secondary school, and never-bullied children. Biometric analyses revealed that stability in victimization over this period was influenced primarily by genetic and shared environmental factors. Regression analyses showed that children's early characteristics such as preexistent adjustment difficulties and IQ predicted chronic versus transitory victimization. Family risk factors for chronic victimization included socioeconomic disadvantage, low maternal warmth, and maltreatment. Our results suggest that bullying intervention programs should consider the role of the victims' behaviors and family background in increasing vulnerability to chronic victimization. Our study highlights the importance of widening antibullying interventions to include families to reduce the likelihood of children entering a pathway toward chronic victimization.

Concurrent and prospective associations between family socioeconomic status, social support and salivary diurnal and hair cortisol in adolescence / Mara BRENDGEN ; Sonia J. LUPIEN ; Ginette DIONNE ; Frank VITARO ; Michel BOIVIN ; Isabelle OUELLET-MORIN in Journal of Child Psychology and Psychiatry, 65-3 (March 2023)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 65-3 (March 2023) . - p.298-307 Titre : Concurrent and prospective associations between family socioeconomic status, social support and salivary diurnal and hair cortisol in adolescence Type de document : texte imprimé Auteurs : Mara BRENDGEN, Auteur ; Sonia J. LUPIEN, Auteur ; Ginette DIONNE, Auteur ; Frank VITARO, Auteur ; Michel BOIVIN, Auteur ; Isabelle OUELLET-MORIN, Auteur Article en page(s) : p.298-307 Index. décimale : PER Périodiques Résumé : Background Exposure to socioeconomic adversity is hypothesized to impact hypothalamic?pituitary?adrenal (HPA) axis activity and cortisol secretion, but existing evidence is inconsistent. Yet, few studies have investigated this association using a developmental approach that considers potential protective contextual factors. This study examined the role of stability and changes in family socioeconomic status (SES) in the prediction of multiple cortisol indicators and tested whether social support moderated these associations. Methods Participants were part of a population-based sample of twin pairs recruited at birth. Family SES was assessed in early childhood (ages 0 5) and mid-adolescence (age 14). Social support was assessed at ages 14 and 19. Diurnal cortisol (n 569) was measured at age 14 at awakening, 30 min later, in the afternoon and evening over four non-consecutive days. Hair cortisol concentration (HCC, n 704) was measured at age 19. All data were collected before the pandemic and multilevel regression models were conducted to account for the nested data structure. Results Youth exposed to lower family SES levels in childhood and mid-adolescence had a flatter diurnal slope and higher HCC compared with those who experienced upward socioeconomic mobility in mid-adolescence. Contrastingly, mid-adolescence SES showed no association with the diurnal slope or HCC for youth from higher-SES households in early childhood. Moreover, youth raised in higher-SES families in early childhood had a higher CAR in mid-adolescence if they reported greater social support in mid-adolescence. Social support also moderated the SES-cortisol association in mid-adolescence, with higher-SES youth showing higher awakening cortisol secretion when reporting more social support. Conclusions Our findings support the hypothesis that early socioeconomic adversity sensitizes HPA axis activity to later socioeconomic disadvantage, which may bear consequences for socioemotional and behavioral functioning.

Cybervictimization in adolescence and its association with subsequent suicidal ideation/attempt beyond face-to-face victimization: a longitudinal population-based study / Léa C. PERRET in Journal of Child Psychology and Psychiatry, 61-8 (August 2020)

METHODS: Participants were members of the Quebec Longitudinal Study of Child Development (QLSCD), a prospective birth cohort of 2,120 individuals followed from birth (1997/98) to age 17 years (2014/15). Cybervictimization and face-to-face victimization experienced since the beginning of the school year, as well as serious suicidal ideation and/or suicide attempt were self-reported at ages 13, 15 and 17 years. RESULTS: In cross-sectional analyses at 13, 15 and 17 years, adolescents cybervictimized at least once had, respectively, 2.3 (95% CI = 1.64-3.19), 4.2 (95% CI = 3.27-5.41) and 3.5 (95% CI = 2.57-4.66) higher odds of suicidal ideation/attempt after adjusting for confounders including face-to-face victimization, prior mental health symptoms and family hardship. Sensitivity analyses suggested that cybervictimization only and both cyber- and face-to-face victimization were associated with a higher risk of suicidal ideation/attempt compared to face-to-face victimization only and no victimization; however, analyses were based on small n. In prospective analyses, cybervictimization was not associated with suicidal ideation/attempt 2 years later after accounting for baseline suicidal ideation/attempt and other confounders. In contrast, face-to-face victimization was associated with suicidal ideation/attempt 2 years later in the fully adjusted model, including cybervictimization. CONCLUSIONS: The cross-sectional association between cybervictimization and suicidal ideation/attempt is independent from face-to-face victimization. The absence of a prospective association suggested short-term effects of cybervictimization on suicidal ideation/attempt.

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)

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.
