  abstract  = {Little is known about the current state of research on the involvement of young people in hate speech. Thus, this systematic review presents findings on a) the prevalence of hate speech among children and adolescents and on hate speech definitions that guide prevalence assessments for this population; and b) the theoretical and empirical overlap of hate speech with related concepts. This review was guided by the Cochrane approach. To be included, publications were required to deal with real-life experiences of hate speech, to provide empirical data on prevalence for samples aged 5 to 21 years and they had to be published in academic formats. Included publications were full-text coded using two raters (kappa = .80) and their quality was assessed. The string-guided electronic search (ERIC, SocInfo, Psycinfo, Psyndex) yielded 1,850 publications. Eighteen publications based on 10 studies met the inclusion criteria and their findings were systematized. Twelve publications were of medium quality due to minor deficiencies in their theoretical or methodological foundations. All studies used samples of adolescents and none of younger children. Nine out of 10 studies applied quantitative methodologies. Eighteen publications based on 10 studies were included. Results showed that frequencies for hate speech exposure were higher than those related to victimization and perpetration. Definitions of hate speech and assessment instruments were heterogeneous. Empirical evidence for an often theorized overlap between hate speech and bullying was found. The paper concludes by presenting a definition of hate speech, including implications for practice, policy, and research.},

  abstract  = {Although hate speech is widely recognized as an online phenomenon, very few studies have investigated hate speech among adolescents in offline settings (e.g., schools). At the same time, not much is known about countering hate speech (counterspeech) among adolescents and which factors are associated with it. To this end, the present study used the socio-ecological framework to investigate the direct and indirect links among one contextual factor (i.e., classroom climate) and two intrapersonal factors (i.e., empathy for victims of hate speech, self-efficacy regarding intervention in hate speech) to understand counterspeech among adolescents. The sample is based on self-reports of 3,225 students in Grades 7 to 9 (51.7\% self-identified as female) from 36 schools in Germany and Switzerland. Self-report questionnaires were administered to measure classroom climate, empathy, self-efficacy, and counterspeech. After controlling for adolescents' grade, gender, immigrant background, and socioeconomic status (SES), the 2-(1-1)-1 multilevel mediation analysis showed that classroom climate (L2), empathy for victims of hate speech (L1), and self-efficacy toward intervention in hate speech (L1) had a positive effect on countering hate speech (L1). Classroom climate (L2) was also positively linked to empathy for victims of hate speech (L1), and self-efficacy toward intervention in hate speech (L1). Furthermore, classroom climate (L2) was indirectly associated with countering hate speech (L1) via greater empathy (L1) and self-efficacy (L1). The findings highlight the need to focus on contextual and intrapersonal factors when trying to facilitate adolescents' willingness to face hate speech with civic courage and proactively engage against it.},

  abstract  = {Objective: The open expression of hatred, hostility, and violence against minorities has become a common online phenomenon. Adolescents are at particular risk of being involved in different hate speech roles (e.g., witness, perpetrator). However, the correlates of their involvement as perpetrators and the mechanisms that might explain their involvement in hate speech across different roles have not yet been thoroughly investigated. To this end, this study investigates moral disengagement and empathy as correlates of online hate speech perpetration and the moderation effects of empathy and moral disengagement in the relationship between witnessing and perpetrating online hate speech. Method: The sample consists of 3,560 7th to 9th graders from 40 schools in Germany and Switzerland. Self-report questionnaires were utilized to assess online hate speech involvement, moral disengagement, and empathy. Results: Multilevel regression analyses revealed that moral disengagement and witnessing online hate speech were positively associated with online hate speech perpetration, while empathy was negatively associated with it. The findings also showed that the positive relationship between witnessing and perpetrating online hate speech was stronger at higher levels of moral disengagement and weaker when moral disengagement was low. The association between witnessing and perpetrating online hate speech was weaker when adolescents had higher rather than lower levels of empathy. Conclusions: The findings underscore the need for prevention efforts to accelerate moral engagement and empathy as critical future directions in hate speech prevention. This study also contributes to our understanding of underlying mechanisms that explain adolescents' involvement across different roles in hate speech.},

  abstract  = {To date, little has been known about teachers' success in bullying interventions. Thus, the present study analyzes how successfully teachers intervene in real bullying situations, based on an analysis of 1,996 reports by German students aged between 12 and 15 (49.2\% female) from 24 schools. Predictors of success included intervention strategy (authoritarian-punitive, supportive-individual, supportive-cooperative intervention), bullying form (physical, verbal, relational, cyber), and the student's bullying role (bully, victim, bystander) in the particular situation. Multilevel analyses showed that supportive-cooperative intervention strategies were the most successful in dealing with bullying in both the short and long term. In the long term, students evaluated teachers as being more successful in dealing with cyberbullying compared with physical bullying. Compared with students who observed bullying, students who perpetrated it were less likely to report that teachers' interventions were successful in the short term. Implications for bullying intervention, preservice teacher-training, and future research are discussed.},

  abstract  = {A substantial amount of research has revealed that cyberbully-victims have more emotional and behavioral problems than either cyberbullying victims or perpetrators. However, until now, little research has been conducted into the factors that contribute to the interplay between cyberbullying victimization and perpetration. The purpose of this study was to examine the relationship between cyberbullying victimization, perpetration, and two emotional components of alexithymia, namely difficulties in identifying and describing one's own feelings. Self-report questions were administered to 1549 adolescents between 12 and 18 years old (M = 14.51; SD = 1.68; 42.1\% (n = 652) male) from Germany and Thailand. Results showed that cyberbullying victimization and alexithymia are associated with cyberbullying perpetration. Moreover, alexithymia mediated the associations between cyberbullying victimization and adolescents' cyberbullying perpetration. Consequently, we suggest that the ability to describe and identify one's own feelings might be important for understanding the link between cyberbullying, victimization, and perpetration. The results may help develop prevention and intervention programs focused on reducing cyberbullying.},
