“…Due to the classroom context, students might as bystanders have concerns about their own social status and vary in fear of being attacked or victimized and their belief in their ability to intervene, whether they perceive the aggression as wrong, and in what ways they attribute cause and responsibility, which has been suggested in qualitative studies examining students’ perspectives ( Forsberg et al, 2014 , 2018 ; Chen et al, 2016 ; Strindberg et al, 2020 ), Accordingly, previous work has indicated that bystander behaviors are contingent upon classroom contexts. Students who are witnessing peer victimization in school are more likely to defend a victim if they belong to a classroom with a more supportive, caring, friendly and respectful climate among the peers ( Thornberg et al, 2017 ), with a greater collective efficacy to stop peer aggression ( Sjögren et al, 2020 ; Thornberg et al, 2020 ), that have stronger antibullying norms ( Peets et al, 2015 ; Lucas-Molina et al, 2018 ; Thornberg et al, 2022 ), and in which bullies are relatively unpopular ( Pouwels et al, 2019 ). In addition to having direct associations with bystander behaviors, and in accordance with social cognitive theory ( Bandura, 1986 , 1997 , 2016 ), classroom variables can interact with individual variables in their influence on bystander behaviors (e.g., Gini et al, 2020 ).…”
