This study examined whether students' bystander behaviours in peer victimisation were associated with individual (IMD) and classroom collective moral disengagement (CMD). Self-report survey data were analysed from 1577 Swedish students in fifth grade. Multilevel analyses revealed that, when witnessing peer victimisation, students more often sided…

Background: The link between peer victimization and somatic problems is well-established. What is currently understudied is under what contextual conditions victims' health might be most likely to be compromised. Studies demonstrate that victims suffer from poorer adjustment when they belong to a group in which victimization is less normative…

The study investigated the longitudinal relations between students' roles in bullying (i.e., bullying, defending, and victimization) and social status within the class. Moreover, we tested the hypothesis that students' perception of their own status may mediate these relations. A sample of 432 early adolescents completed peer nominations for…

This study examined whether defending and passive bystanding during peer victimization episodes were associated with individual- and classroom-level efficacy to stop peer victimization. Self-report survey data were analyzed from 1,467 Swedish fourth-grade students (mean age = 10.55) from 100 classrooms in 63 schools. Multilevel analyses revealed…

This study examined the links between seven specific mechanisms of moral disengagement and indirect bullying, direct bullying, and pro-aggressive bystander behavior. In addition, the moderating role of gender on these associations was examined. Participants were 317 Swedish students in Grades 4 to 8 (X-bar[subscript age]=12.6, SD = 1.35; 62%…

The aim of the current study was to examine whether collective moral disengagement in the classroom was associated with bullying perpetration and victimisation. One-thousand-and-fifty-four students from 70 classrooms in 29 schools in the middle and southern parts of Sweden completed a questionnaire in their classroom. In line with the hypotheses,…

The aim of this study was to examine how different bystander roles in peer victimisation situations relate to moral disengagement, defender self-efficacy, and student-teacher relationship quality. Self-reported survey data were collected from 333 middle and junior high school students (10-15 years of age) from four schools in Sweden. Random…

Bullying is a moral transgression. Recognizing the importance of approaching bullying from a moral perspective, the present study examines whether children's judgments and reasoning to justify their judgments differ between bullying and repeated conventional transgressions. Our study also explores differences by gender and differences among…

Background: Given the severity of outcomes associated with involvement in bullying and the resources spent in an effort to reduce its prevalence, it is important to investigate trends in the bullying's occurrence. The main aim of this study was to identify trends from 2002 to 2010 in prevalence of bullying and victimization among Italian…

The aim of the present study was to test whether teacher-student relationship (TSR) quality and student-student relationship (SSR) quality at class level and class moral disengagement (CMD), considered together in a single model, were related to class prevalence of victims (CPV) of bullying. A sample of 899 Swedish children was recruited from 43…

This study investigates possible individual and class correlates of defending and passive bystanding behavior in bullying, in a sample of 1,825 Italian primary school (mean age = 10 years 1 month) and middle school (mean age = 13 years 2 months) students. The findings of a series of multilevel regression models show that both individual (e.g.,…

Background: Using data from the 2006 Health Behavior in School-aged Children (HBSC) survey, the prevalence of 6 forms of bullying (physical, verbal, relational, sexual, cyber, and racist), and the role of smoking and drinking in bullying was examined among Italian adolescents for this study. Methods: The sample was composed of 2667 Italian middle…
