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.

Child-care quality moderates the association between maternal depression and children's behavioural outcome / Justine CHARROIS in Journal of Child Psychology and Psychiatry, 58-11 (November 2017)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 58-11 (November 2017) . - p.1210-1218 Titre : Child-care quality moderates the association between maternal depression and children's behavioural outcome Type de document : Texte imprimé et/ou numérique Auteurs : Justine CHARROIS, Auteur ; Sylvana M.

HERBA, Auteur Article en page(s) : p.1210-1218 Langues : Anglais (eng) Mots-clés : Behaviour problems  child care  maternal depression  longitudinal study Index. décimale : PER Périodiques Résumé : Background Maternal depression is a risk factor for adverse outcomes in the child, including emotional and behavioural difficulties. There is evidence that child care attendance during the preschool years may moderate associations between familial risk factors and child outcome. However, the possibility that high-quality child care provides protection for children exposed to maternal depression or that low-quality child care provides additional risk has not been investigated. We study whether child-care quality moderates the association between probable history of maternal depression (PMD) and child behavioural and emotional outcomes over the preschool period. Methods Within a longitudinal study, we examined PMD (no depression; clinical PMD before the child's birth; subclinical PMD from 0 to 5 years; clinical PMD from 0 to 5 years), child-care quality and child emotional and behavioural difficulties at the ages of 2, 3 and 4 years. Child-care quality was evaluated in settings, and trajectories were calculated to reflect (a) global quality and (b) two quality subfactors: ‘Teaching and interactions’ and ‘Provision for learning’. Data were analysed for 264 families. Results Significant interactions emerged between clinical PMD and global quality of child care for children's externalising behaviour (b = ?.185, p = .008), more specifically hyperactivity/inattention (b = ?.237, p = .002). In the context of clinical PMD, children attending high-quality child care presented fewer difficulties than those attending a low-quality care. Child-care quality was not associated with outcomes for children whose mothers did not report a PMD or a PMD before their birth. Conclusions In the context of PMD, high-quality child care was associated with fewer behavioural problems and may thus constitute a protective factor.

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.

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.

A person-centered approach to studying associations between psychosocial vulnerability factors and adolescent depressive symptoms and suicidal ideation in a Canadian longitudinal sample / Lalou TISSEYRE in Development and Psychopathology, 33-1 (February 2021)

HERBA, Auteur Article en page(s) : p.351-362 Langues : Anglais (eng) Mots-clés : adolescence  depression  risk factors  sex differences  suicidal behavior Index. décimale : PER Périodiques Résumé : This study used a person-centered approach to identify subgroups of adolescents who are at risk for depression and suicidal ideation. Latent class analysis was first applied to 1,290 adolescents from a Canadian cohort study in order to identify latent vulnerability subtypes based on 18 psychosocial vulnerability factors. Logistic regression analyses were conducted to study the associations between class membership and depressive symptoms and suicidal ideation 2 years later. The moderating role of sex in the associations between latent classes and depressive symptoms was explored. Five latent classes were identified: Low Vulnerability (42%), Substance Use Only (13%), Moderate Vulnerability (28%), Conduct Problems (8%) and High Vulnerability (9%). Compared with the Low Vulnerability class, the probabilities of presenting depressive symptoms were higher for the Substance Use Only class, OR = 1.93, 95% CI [1.21, 3.06], the Moderate Vulnerability class, OR = 2.96, 95% CI [2.09, 4.20], the Conduct Problems class, OR = 3.03, 95% CI [1.84, 4.98], and the High Vulnerability class, OR = 5.4, 95% CI [3.42, 8.53]. Furthermore, interaction effects with sex were identified in relation to depressive symptoms only. The probability of presenting suicidal ideation was higher only for the High Vulnerability class, OR = 4.51, 95% CI [2.41, 8.43]. This study highlights the importance of a person-centered perspective that considers both vulnerability subtypes and sex because these associations are complex rather than linear or additive.

Polygenic risk score and peer victimisation independently predict depressive symptoms in adolescence: results from the Quebec Longitudinal Study of Children Development / Léa C. PERRET in Journal of Child Psychology and Psychiatry, 64-3 (March 2023)

This study tested whether having a genetic predisposition to developing depression increased the risk of experiencing depressive symptoms in peer victimised youth. To date, no study has explored such gene-environment interaction using a polygenic risk score for depression (PRS-depression) in the context of peer victimisation and depressive symptoms in adolescence. Methods The sample included 748 participants born in 1997/98 from the Quebec Longitudinal Study of Child Development with genotype data and prospectively collected information on peer victimisation (12-13 years) obtained from both self- and teacher-reports, as well as self-reported depressive symptoms (15-17 years). The PRS-depression was based on the genome-wide association meta-analysis of broad depression by Howard et al. (2019). Results Self- and teacher-reported peer victimisation in early adolescence were both associated with depressive symptoms in adolescence (Î2=0.34, p < .001; Î2=0.14, p=.001 respectively), and this association remained significant when accounting for PRS-depression (Î2=0.33, p < .001; Î2=0.13, p=.002 respectively). PRS-depression was independently associated with depressive symptoms, but there was no significant PRS-depression by peer victimisation interaction (self-reported and teacher-reported). PRS-depression was correlated with self-reported, but not teacher-reported, peer victimisation. Conclusions Our findings suggested that a partial measure of an individual's genetic predisposition to depression, as measured by PRS-depression, and being exposed to peer victimisation (self- and teacher-reported) were independently associated with depressive symptoms in adolescence. Furthermore, PRS-depression did not exacerbate the risk of depressive symptoms among adolescents who had been peer victimised. Lastly, we found evidence of a gene-environment correlation between PRS-depression and self-reported peer victimisation. Future studies are needed to replicate this finding and to further understand the role of genetic predispositions in experiencing depressive symptoms following peer victimisation.
