“…Based on the following theories and research, we hypothesized that affiliation with delinquent peers at school is the potential psychosocial mediator of the association between family conflict and school bullying. For example, previous research has shown that adolescents who experience family conflict have more strained or alienated relationships with their parents (e.g., Fernandes-Alcantara, 2016;Noh & Kim, 2021;Roche & Barker, 2017), which increases their distrust in social relationships and decreases social skills and emotional functioning (Boutelle et al, 2009;Heinze et al, 2020;Van Rosmalen-Nooijens et al, 2017). Once they go to school to interact with their school peers, mainstream peers may dislike them or reject them because of their social deficits (Farmer et al, 2003;Gregson et al, 2017), increasing their chance to gravitate toward delinquent peers because they have few alternative peers to interact with (Lansford et al, 2014).…”
