5-HTTLPR moderates the effect of relational peer victimization on depressive symptoms in adolescent girls / Corina BENJET in Journal of Child Psychology and Psychiatry, 51-2 (February 2010)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 51-2 (February 2010) . - p.173-179 Titre : 5-HTTLPR moderates the effect of relational peer victimization on depressive symptoms in adolescent girls Type de document : texte imprimé Auteurs : Corina BENJET, Auteur ; Renee THOMPSON, Auteur ; Ian H. GOTLIB, Auteur Année de publication : 2010 Article en page(s) : p.173-179 Langues : Anglais (eng) Mots-clés : Peer-victimization bullying depression genetic-polymorphisms 5-HTTLPR Index. décimale : PER Périodiques Résumé : Background: Relational peer victimization is associated with internalizing symptoms. Compared to boys, girls are more likely to be both relationally victimized by peers and distressed by the victimization. While previous studies have reported that a functional polymorphism in the promoter region of the serotonin transporter gene (5-HTTLPR) moderates the effect of stressful life events on depressive symptoms, the present study is the first to evaluate the interaction of this polymorphism with relational peer victimization to predict level of depressive symptoms in young girls. Methods: Participants were 78 girls ages 10 to 14 who had no current or past Axis I disorder. Girls were genotyped for 5-HTTLPR; peer victimization was assessed with the Social Experiences Questionnaire, and depressive symptoms with the Children's Depression Inventory. Results: The 5-HTTLPR polymorphism alone did not predict level of depressive symptoms; the interaction of 5-HTTLPR and relational peer victimization, however, was a significant predictor of depressive symptoms. Follow-up analyses indicated that peer victimization significantly predicted level of depressive symptoms only for girls who were homozygous for the short allele, and not for girls homozygous for the long allele or who were heterozygous for the short and long alleles. Conclusions: The findings support the diathesis-stress model of depression: having two 5-HTTLPR short alleles confers vulnerability to depressive symptoms in adolescent girls when they experience relational peer victimization. These findings also suggest that relational peer victimization, at least for girls with genetic vulnerability, is a significant source of stress and should be recognized in the monitoring and prevention of bullying.

Are there negative cycles of peer victimization and rejection sensitivity? Testing ri-CLPMs in two longitudinal samples of young adolescents / Gerine M.A. LODDER ; Matteo GILETTA ; Melanie J. ZIMMER-GEMBECK ; Berna GÃœROÄžLU ; René VEENSTRA in Development and Psychopathology, 36-2 (May 2024)

Drawing from Social Information Processing Theory, we hypothesized that victimization leads to higher levels of rejection sensitivity, which would put adolescents at risk for higher future victimization. Data were collected in a four-wave study with 233 Dutch adolescents starting secondary education (Mage = 12.7 years), and a three-wave study with 711 Australian adolescents in the last years of primary school (Mage = 10.8 years). Random-intercept cross-lagged panel models were used to disentangle between-person from within-person effects. In each sample, a significant between-person association was found: adolescents with higher levels of victimization as compared to their peers also reported higher levels of rejection sensitivity. At the within-person level, all concurrent associations between individual fluctuations of victimization and rejection sensitivity were significant, but there were no significant cross-lagged effects (except in some sensitivity analyses). These findings demonstrate that victimization and rejection sensitivity are interrelated, but there may not be negative victimization-rejection sensitivity cycles during the early-middle adolescent years. Possibly, cycles establish earlier in life or results are due to shared underlying factors. Further research is needed examining different time lags between assessments, age groups, and contexts.

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 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.

Associations between forms of aggression and peer victimization: Does prosocial behavior matter? / Carlos R. SANCHEZ ; John L. COOLEY ; Drew E. WINTERS ; Brianna T. RICKER ; Paula J. FITE in Development and Psychopathology, 37-1 (February 2025)

The goal of the current study was to investigate prosocial behavior as a moderator of these links over a 2-year period during middle childhood. Participants included 410 third-grade students (53% boys) and their homeroom teachers. Results indicated that prosocial behavior was associated with lower initial levels of victimization, whereas relational aggression was associated with higher initial levels of victimization. Physical aggression predicted more stable patterns of victimization over time, and prosocial behavior moderated the prospective link from relational aggression to peer victimization; specifically, relational aggression predicted decreases in victimization at higher levels of prosocial behavior and more stable patterns over time when levels of prosocial behavior were low. Further, gender differences were observed in the moderating effect of prosocial behavior on the prospective link from physical aggression to peer victimization, such that it served as a risk factor for boys and a protective factor for girls.

Bidirectional spillover between maladaptive parenting and peer victimization and the mediating roles of internalizing and externalizing problems: A within-person analysis among Chinese early adolescents / Xue GONG ; Guangying LU ; Xiangrong XU ; Haiyan ZHAO ; Xiaoli YANG in Development and Psychopathology, 35-4 (October 2023)

Although theoretically expected reciprocal associations between changes in maladaptive parenting and adolescent peer victimization exist, there is a lack of studies that examine this link and address the mediating mechanisms at the within-person level. This longitudinal study examined reciprocal relations between peer victimization and two types of maladaptive parenting including harsh punishment and psychological control, and the potential mediating roles of internalizing and externalizing problems within these relations, by disentangling between- and within-person effects. A total of 4,731 Chinese early adolescents (44.9% girls; Mage = 10.91 years, SD = 0.72) participated in a four-wave longitudinal study with 6-month intervals. The results of random intercept cross-lagged panel modeling showed: (a) harsh punishment did not directly predict peer victimization, and vice versa; (b) psychological control directly predicted peer victimization, and vice versa; (c) psychological control indirectly predicted peer victimization via internalizing problems, and peer victimization also indirectly predicted psychological control via internalizing problems. These findings provide evidence of a bidirectional spillover effect between psychological control and peer victimization at the within-person level, suggesting Chinese early adolescents may become caught in a vicious cycle directly or indirectly via their internalizing problems.
