Background: Bullying and cyberbullying are serious public health concerns that involve more roles beyond the bully and the victim (pro-bullies, defenders, bystanders). However, students often perceive the phenomena as dyadic. Aim: The purpose was to examine students' perceptions of different roles when observing bullying and cyberbullying scenes…

The aim of the present study was to investigate and clarify the association between authoritative teaching at the classroom level and bullying perpetration and victimization among Swedish upper elementary school students. For this purpose, authoritative teaching was analyzed both as combined construct, and as the effects of the two dimensions that…

Despite the wealth of knowledge about the impact of bullying victimization, information gaps exist about how traditional and cyber bullying in early adolescence is associated with emotional wellbeing, namely, indicators of positive wellbeing. Therefore, this study investigated associations between different types of bullying victimization and…

The goal of the current study was to examine the potential mediating role of two types of school avoidance (absenteeism, in-class avoidant behaviors such as asking to leave the classroom) on the relations between peer victimization and two academic outcomes [standardized test scores, grade point average (GPA)]. Participants included 1815 diverse…

The relationship between teachers and students plays a critical role in the psychosocial development of children and youth. The literature documents numerous studies over several decades that have examined links between teacher-student relationships (TSRs) and bullying perpetration and victimization among students. The present meta-analytic study…

The association between relational victimization and risk-taking development in children is understudied. Also, it is not clear how the social classroom norm may affect this link. The aim of this study was, therefore, to investigate the link between relational victimization and risk-taking behavior in elementary schoolchildren, and the potential…

This study examines the relationship between English Learner (EL) classification, language program type, and peer victimization using nationally representative data from the Early Childhood Longitudinal Study- Kindergarten Class of 2011. Leveraging a sample of 9,562 children, this study investigates whether Dual-Language programs serve as a…

Peer victimization in schools most often occurs in the presence of bystanders. When bystanders intervene on behalf of the victims, they are often successful in stopping the victimization. Defender self-efficacy (i.e., the belief in one's ability to successfully defend victims) has consistently been associated with greater defending and less…

The aim of the present study was to investigate whether authoritative teaching at the classroom-level was associated with bullying victimisation, and how this association evolved over the course of upper elementary school (i.e. in grades 4 through 6) by estimating whether the association declined with time. Data came from the first three waves of…

Peer victimization in schools is a growing concern in China, linked to increased emotional difficulties and behavioral difficulties. A positive school climate may serve as a protective factor against both peer victimization and its adverse outcomes. This study examined the longitudinal relations between peer victimization, aggression, and school…

The study aims to examine changes over time in school victimization and climate in Israel, and whether these changes varied between Jewish and Arab schools and schools with different SES. A secondary analysis of the Ministry of Education database of structured student surveys regarding victimization and climate, was conducted during 2008-2019. All…

Mainstream anti-bullying interventions can reduce primary school-level victimisation by 15-16% and bullying perpetration by 19%-20% ("Aggression and Violent Behavior," 2019; 45: 111-133). Less is known about anti-bullying interventions for pupils with special educational needs and disabilities (SEND) even though they are at least 2-4…

This dissertation includes three individual articles that explore the relationship between witnessing bullying and defending behavior among students who are bystanders of bullying. Chapter One provides the rationale and purpose of this dissertation and an overview of the three articles that comprise it. Chapter Two employed a cross-sectional…

To date, research has rarely addressed the association between individuals' past cyber victimization and their position taking as bystanders in offline bullying situations, much less the psychosocial mechanism underpinning that association. By applying a social-ecological diathesis-stress model, the present study marked an initial effort to…

The extent to which teachers make changes in classroom seating reflects, in part, the degree to which they value promoting positive peer relationships in the classroom. We assessed the frequency with which teachers made both minor (i.e., involving only 2-3 students) and major (involving half or more students in the class) changes in classroom…
