Dynamic pathways between rejection and antisocial behavior in peer networks: Update and test of confluence model / Olga KORNIENKO in Development and Psychopathology, 32-1 (February 2020)  

Public ISBD [article]  inDevelopment and Psychopathology > 32-1 (February 2020) . - p.175-188 Titre : Dynamic pathways between rejection and antisocial behavior in peer networks: Update and test of confluence model Type de document : Texte imprimé et/ou numérique Auteurs : Olga KORNIENKO, Auteur ; Thao HA, Auteur ; Thomas J. DISHION, Auteur Article en page(s) : p.175-188 Langues : Anglais (eng) Mots-clés : antisocial behavior  longitudinal social network analysis  peer networks  peer rejection  stochastic actor-based modeling Index. décimale : PER Périodiques Résumé : The confluence model theorizes that dynamic transactions between peer rejection and deviant peer clustering amplify antisocial behavior (AB) within the school context during adolescence. Little is known about the links between peer rejection and AB as embedded in changing networks. Using longitudinal social network analysis, we investigated the interplay between rejection, deviant peer clustering, and AB in an ethnically diverse sample of students attending public middle schools (N = 997; 52.7% boys). Adolescents completed peer nomination reports of rejection and antisocial behavior in Grades 6-8. Results revealed that rejection status was associated with friendship selection, and adolescents became rejected if they were friends with others who were rejected. Youth befriended others with similar levels of AB. Significant patterns of peer influence were documented for AB and rejection. As hypothesized, rejected youth with low AB were more likely to affiliate with others with high AB instead of similarly low AB. In contrast, nonrejected youth preferred to befriend others with similarly high or low AB. Results support an updated confluence model of a joint interplay between rejection and AB as ecological conditions that lead to self-organization into deviant clusters in which peer contagion on problem behaviors operates.

Childhood peer network characteristics: genetic influences and links with early mental health trajectories / Eszter SZEKELY in Journal of Child Psychology and Psychiatry, 57-6 (June 2016)  

Public ISBD [article]  inJournal of Child Psychology and Psychiatry > 57-6 (June 2016) . - p.687-694 Titre : Childhood peer network characteristics: genetic influences and links with early mental health trajectories Type de document : Texte imprimé et/ou numérique Auteurs : Eszter SZEKELY, Auteur ; Irene PAPPA, Auteur ; James D. WILSON, Auteur ; Shankar BHAMIDI, Auteur ; Vincent W.V. JADDOE, Auteur ; Frank C. VERHULST, Auteur ; Henning TIEMEIER, Auteur ; Philip SHAW, Auteur Article en page(s) : p.687-694 Langues : Anglais (eng) Mots-clés : Heritability  peer networks  externalizing  internalizing  preschoolers Index. décimale : PER Périodiques Résumé : Background Peer relationships are important for children's mental health, yet little is known of their etiological underpinnings. Here, we explore the genetic influences on childhood peer network characteristics in three different networks defined by rejection, acceptance, and prosocial behavior. We further examine the impact of early externalizing and internalizing trajectories on these same peer network characteristics. Methods Participants were 1,288 children from the Dutch ‘Generation R’ birth cohort. At age 7, we mapped out children's classroom peer networks for peer rejection, acceptance, and prosocial behavior using mutual peer nominations. In each network, genetic influences were estimated for children's degree centrality, closeness centrality and link reciprocity from DNA using Genome-wide Complex Trait Analysis. Preschool externalizing and internalizing trajectories were computed using parental ratings at ages 1.5, 3, and 5 years. Results Of the three network properties examined, closeness centrality emerged as significantly heritable across all networks. Preschool externalizing problems predicted unfavorable positions within peer rejection networks and having fewer mutual friendships. In contrast, children with preschool-internalizing problems were not actively rejected by their peers, but were less well-connected within their social support network. Conclusions Our finding of significant heritability for closeness centrality should be taken as preliminary evidence that requires replication. Nevertheless, it can orient us to the role of genes in shaping a child's position within peer networks. Additionally, social network perspectives offer rich insights into how early life mental health trajectories impact a child's later functioning within peer networks.

A Comprehensive Peer Network Intervention to Improve Social Communication of Children with Autism Spectrum Disorders: A Randomized Trial in Kindergarten and First Grade / Debra M. KAMPS in Journal of Autism and Developmental Disorders, 45-6 (June 2015)  

Public ISBD [article]  inJournal of Autism and Developmental Disorders > 45-6 (June 2015) . - p.1809-1824 Titre : A Comprehensive Peer Network Intervention to Improve Social Communication of Children with Autism Spectrum Disorders: A Randomized Trial in Kindergarten and First Grade Type de document : Texte imprimé et/ou numérique Auteurs : Debra M. KAMPS, Auteur ; Kathy S. THIEMANN-BOURQUE, Auteur ; Linda HEITZMAN-POWELL, Auteur ; Ilene S. SCHWARTZ, Auteur ; Nancy ROSENBERG, Auteur ; Rose MASON, Auteur ; Suzanne COX, Auteur Article en page(s) : p.1809-1824 Langues : Anglais (eng) Mots-clés : Peer networks  Social-communication skills  Text cues Index. décimale : PER Périodiques Résumé : The purpose of this randomized control group study was to examine the effects of a peer network intervention that included peer mediation and direct instruction for Kindergarten and First-grade children with autism spectrum disorders. Trained school staff members provided direct instruction for 56 children in the intervention group, and 39 children participated in a comparison group. Results showed children in the intervention group displayed significantly more initiations to peers than did the comparison group during non-treatment social probes and generalization probes. Treatment session data showed significant growth for total communications over baseline levels. Children in treatment also showed more growth in language and adaptive communication. Finally, teachers’ ratings of prosocial skills revealed significantly greater improvements for the intervention group.
