Data on youth, over-selected for childhood conduct problems (N = 744, 58% childhood conduct problems, 47% girls), were used to examine the link between conduct problems (time 1: Mean age = 12.23) and perceived neighborhood disorder (time 3: M = 14.30). The mediating role of delinquent friends, peer victimization, depressive symptoms, and observer-rated neighborhood disorder (time 2: M = 13.23) were also tested. Conduct problems were associated with higher levels of perceived neighborhood disorder, via delinquent peers and peer victimization. These findings offer new insight into the consequences of perceived neighborhood disorder for health and wellbeing.

Child Psychiatry & Human Development, 2019

The high levels of comorbidity between oppositional/conduct problems and hyperactivity/attention ... more The high levels of comorbidity between oppositional/conduct problems and hyperactivity/attention problems underscore the need for assessing how vulnerability for peer victimization is shaped by overlap among these behavior problems. Children (mean age 8.39, SD = 0.93) participating in a longitudinal study of the development of conduct problems (N = 744; 348 girls) in Quebec, Canada, were evaluated by their teachers regarding experiences of peer verbal and physical victimization every year for 6 years. Parent and teacher ratings of clinically significant oppositional/conduct problems, and hyperactivity/ attention problems, as well as cormorbid opposition defiant/conduct problems and hyperactivity/attention problems were regressed onto trajectories of verbal and physical victimization. While behavior problems (both alone and together) were associated with higher levels of verbal and physical victimization, some variation was observed across rater and type of victimization. Ultimately, these findings suggest the importance of adapting programming for reducing victimization to children with oppositional and conduct problems.

Les adolescents victimisés sont plus à risque de développer par la suite différents problèmes de santé mentale : dépression, anxiété, problèmes extériorisés, conduites suicidaires, etc. (Castellví et al., 2017; Reijntjes et al., 2011; Reijntjes, Kamphuis, Prinzie et Telch, 2010; Ttofi, Farrington, Lösel et Loeber, 2011). Il est donc important d’identifier les facteurs de risque qui contribuent à cette problématique afin de développer des interventions permettant de prévenir ou diminuer la victimisation par les pairs chez les adolescents. À ce propos, peu de chercheurs se sont intéressés à l’influence des facteurs présents dans l’environnement (Hong et Espelage, 2012). Pourtant, selon la théorie de la désorganisation sociale, la présence de certains facteurs dans le quartier, tels que le désordre, créerait des conditions augmentant la violence interpersonnelle (Kubrin et Weitzer, 2003, Sampson,...
