Peer victimization predicts heightened inflammatory reactivity to social stress in cognitively vulnerable adolescents / Matteo GILETTA in Journal of Child Psychology and Psychiatry, 59-2 (February 2018)
[article]
Titre : Peer victimization predicts heightened inflammatory reactivity to social stress in cognitively vulnerable adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Matteo GILETTA, Auteur ; George M. SLAVICH, Auteur ; Karen D. RUDOLPH, Auteur ; Paul D. HASTINGS, Auteur ; Matthew K. NOCK, Auteur ; Mitchell J. PRINSTEIN, Auteur Article en page(s) : p.129-139 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Background During adolescence, peer victimization is a potent type of social stressor that can confer enduring risk for poor mental and physical health. Given recent research implicating inflammation in promoting a variety of serious mental and physical health problems, this study examined the role that peer victimization and cognitive vulnerability (i.e. negative cognitive styles and hopelessness) play in shaping adolescents’ pro?inflammatory cytokine responses to an acute social stressor. Methods Adolescent girls at risk for psychopathology (n = 157; Mage = 14.73 years; SD = 1.38) were exposed to a laboratory?based social stressor before and after which we assessed salivary levels of three key pro?inflammatory cytokines – interleukin?6 (IL?6), interleukin?1? (IL?1?), and tumor necrosis factor?? (TNF??). Results As hypothesized, adolescents with greater peer victimization exposure exhibited greater increases in IL?6 and IL1?? in response to the laboratory?based social stressor. Moreover, for all three cytokines individually, as well as for a combined latent factor of inflammation, peer victimization predicted enhanced inflammatory responding most strongly for adolescents with high levels of hopelessness. Conclusions The findings reveal a biological pathway by which peer victimization may interact with cognitive vulnerability to influence health in adolescence.

[article]
Titre : Reciprocal associations between peer problems and non-suicidal self-injury throughout adolescence Type de document : Texte imprimé et/ou numérique Auteurs : Lisa DE LUCA, Auteur ; Matteo GILETTA, Auteur ; Ersilia MENESINI, Auteur ; Mitchell J. PRINSTEIN, Auteur Article en page(s) : p.1486-1495 Langues : Anglais (eng) Mots-clés : Female Adolescent Humans Male Self-Injurious Behavior/epidemiology Bullying Peer Group Crime Victims Friends Adolescence bullying peer relationships friendship self-injury Index. décimale : PER Périodiques Résumé : BACKGROUND: Peer problems have emerged as important predictors of Non-Suicidal Self-Injury (NSSI) development during adolescence. However, the possibility that adolescents who engage in NSSI may, in turn, be at increased risk for experiencing difficulties with their peers has rarely been examined. This study investigated the reciprocal associations between peer problems (e.g. peer victimization, friendship stress and loneliness) and NSSI throughout adolescence, distinguishing between- and within-person effects. METHOD: Participants were 866 adolescents (54.5% females; M(age) =13.12 years, SD=0.78), who took part in six waves of data collection. Adolescents completed self-report measures of NSSI, friendship stress and loneliness and they took part in a peer nomination procedure to assess peer victimization. Random Intercept Cross-Lagged Panel Models (RI-CLPMs) were used to estimate within-person cross-lagged effects between each peer problem and NSSI from Grade 7 to 12. RESULTS: After accounting for between-person associations between peer problems and NSSI, results indicated that higher-than-usual levels of NSSI predicted higher-than-usual levels of adolescents' own friendship stress, loneliness and peer victimization at the subsequent time point. Yet, sensitivity analyses revealed that most of these effects were strongly attenuated and explained by within-person fluctuations in depressive symptoms. No within-person cross-lagged effects from peer problems to NSSI were found. CONCLUSIONS: Findings highlight that the associations between peer problems (i.e. friendship stress, loneliness) and NSSI may be largely explained by shared underlying factors; yet, some evidence also suggests that NSSI engagement may increase adolescents' risk to experience difficulties in the relationships with their peers, in part via increases in depressive symptoms.

Titre : Suicide ideation among high-risk adolescent females: Examining the interplay between parasympathetic regulation and friendship support Type de document : Texte imprimé et/ou numérique Auteurs : Matteo GILETTA, Auteur ; Paul D. HASTINGS, Auteur ; Karen D. RUDOLPH, Auteur ; Daniel J. BAUER, Auteur ; Matthew K. NOCK, Auteur ; Mitchell J. PRINSTEIN, Auteur Article en page(s) : p.1161-1175 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Poor physiological self-regulation has been proposed as a potential biological vulnerability for adolescent suicidality. This study tested this hypothesis by examining the effect of parasympathetic stress responses on future suicide ideation. In addition, drawing from multilevel developmental psychopathology theories, the interplay between parasympathetic regulation and friendship support, conceptualized as an external source of regulation, was examined. At baseline, 132 adolescent females (M age = 14.59, SD = 1.39) with a history of mental health concerns participated in an in vivo interpersonal stressor (a laboratory speech task) and completed self-report measures of depressive symptoms and perceived support within a close same-age female friendship. Respiratory sinus arrhythmia (RSA) was measured before and during the speech task. Suicide ideation was assessed at baseline and at 3, 6, and 9 months follow-up. The results revealed that females with greater relative RSA decreases to the laboratory stressor were at higher risk for reporting suicide ideation over the subsequent 9 months. Moreover, parasympathetic responses moderated the effect of friendship support on suicide ideation; among females with mild changes or higher relative increases in RSA, but not more pronounced RSA decreases, friendship support reduced risk for future suicide ideation. Findings highlight the crucial role of physiological and external regulation sources as protective factors for youth suicidality.
