Cyberbullying in context: Direct and indirect effects by low self-control across 25 European countries

Alexander T. Vazsonyi; Hana Macháčková; Anna Ševčíková; David Šmahel; Alena Černá

Random samples of at least 1,000 youth, ages 9 to 16 years, from 25 European countries (N = 25,142) were used to test the salience of low self-control on cyberbullying perpetration and victimization (direct and indirect effects), framed by a cross-cultural developmental approach. Path models, which provided evidence of invariance by sex, tested the hypothesized links among low self-control as well as known correlates, including offline perpetration and victimization, and externalizing behaviours. Results showed positive associations between online and offline bullying behaviours (perpetration and victimization), and, more interestingly, both direct but mostly indirect effects by low self-control on cyberbullying perpetration and victimization; externalizing behaviours had little additional explanatory power. Importantly, multi-group tests by country samples provided evidence of quite modest differences in the tested links across the 25 developmental contexts, despite some observed differences in the amount of variance explained in the dependent measures.

Although the research on cyberbullying has increased dramatically in recent years, still little is known about how cyberbullying participant groups (i.e., cyberbullies, cybervictims, and cyberbully-victims) differ from one another. This study aims to discriminate between these groups at an individual and relational level by controlling for age and gender. Self-control, offline aggression, and self-esteem are analyzed as individual-level variables. Parental attachment and peer rejection are involved as relational-level variables. A total of 2,092 Czech adolescents aged 12 to 18 were enrolled from a random sample of 34 primary and secondary schools located in the South Moravian region of the Czech Republic. Discriminant function analyses indicated that the participant groups are discriminated by two functions. The first function increases the separation between cyberbullies and cyberbully-victims from cybervictims, indicating that cyberbullies and cyberbully-victims are similar to each other in terms of low self-control, offline aggression, and gender, and have higher scores on measures of low self-esteem and offline aggression. However, cyberbully-victims had the highest scores on these measures. The second function discriminates between all three groups, which indicates that those variables included in the second function (i.e., parental attachment, peer rejection, self-esteem, and age) distinguish all three involved groups.Although the research on cyberbullying has increased dramatically in recent years, still little is known about how cyberbullying participant groups (i.e., cyberbullies, cybervictims, and cyberbully-victims) differ from one another.

Although cyberbullying is a well-studied online risk, little is known about the effectiveness of various coping strategies for its victims. Therefore, this study on 2,092 Czech children aged 12-18 examined which coping strategies were applied most often and to what extent victims of cyber aggression judged them to be effective. Effectiveness was measured in two ways: the extent to which the coping strategy buffered negative emotions, and the extent to which it stopped the cyber aggression. The subsample of 422 respondents (68% girls) who experienced online attacks was divided into two groups: victims of cyberbullying, who experienced long-term and severe victimization, and victims of less severe online harassment. The selection of strategies was compared between these groups and the most prevalent and effective strategies were identified. Overall, respondents in both groups used more than one strategy at once, but for victims of cyberbullying, most of the strategies proved less effective. Both groups showed similar patterns in their use of technical solutions, and both quite frequently sought social support. Also, both groups showed a low tendency for retaliation. Large differences were found in how respondents employed cognitive responses, such as trying to detach mentally from bullying incidents; these strategies were less frequent among victims of cyberbullying. In terms of effectiveness, victims of harassment considered technical solutions such as blocking contacts on social websites, seeking support, or ignoring the bully on purpose the most effective in stopping victimization, as opposed to victims of cyberbullying, who found them less effective, even though they used them as frequently as victims of online harassment. Differences in the effectiveness of coping strategies are discussed with regard to the intervention and prevention of cyberbullying.

Bystanders’ Supportive and Passive Responses to Cyberaggression

ABSTRACT Bystanders in cyberaggression can support the victim, join the aggressor, or remain passive. We examined how supportive and passive adolescent Czech cyberbystanders (N = 443, ages 12–18) differ in terms of individual characteristics, emotional responses, and contextual factors. The most substantial distinguishing factor between the two groups turned out to be whether they had received a request to help the victim. After such a request, cyberbystanders supported the victim; moreover, most of those who had not been asked reported that they would have actively reacted to a request for help. The findings also showed the significant role of immediate empathic response, which increased the odds of support even after controlling for individual characteristics. The results are discussed with regard to prevention and intervention efforts.

Meeting online strangers offline: The nature of upsetting experiences of adolescent girls

Abstract The present study focuses on meeting online strangers face-to-face. This activity represents one of the least prevalent but also most feared online risks for youth. Due to the low number of youth experiencing upsetting meetings and the dominance of quantitative research designs in the area, the current state of knowledge does not provide a clear view of what happens at meetings that youths find upsetting. The aim of the present study is to enrich knowledge in this area by exploring such upsetting experiences in more depth by using qualitative methodology. Based on 14 interviews with Czech girls aged 15 to 18, who reported upsetting meetings with online strangers, the study identifies the discrepancy between expectations and reality as the core reason for these negative feelings. There were several reasons for this discrepancy: different developmental phases, related different experiences with romantic relationships, and exaggeration of impressions formed online.
