Extending the school grounds?--Bullying experiences in cyberspace

Jaana Juvonen; Elisheva F. Gross

BACKGROUND Bullying is a national public health problem affecting millions of students. With the rapid increase in electronic or online communication, bullying is no longer limited to schools. The goal of the current investigation was to examine the overlap among targets of, and the similarities between, online and in-school bullying among Internet-using adolescents. Additionally, a number of common assumptions regarding online or cyberbullying were tested. METHODS An anonymous Web-based survey was conducted with one thousand four hundred fifty-four 12- to 17-year-old youth. RESULTS Within the past year, 72% of respondents reported at least 1 online incident of bullying, 85% of whom also experienced bullying in school. The most frequent forms of online and in-school bullying involved name-calling or insults, and the online incidents most typically took place through instant messaging. When controlling for Internet use, repeated school-based bullying experiences increased the likelihood of repeated cyberbullying more than the use of any particular electronic communication tool. About two thirds of cyberbullying victims reported knowing their perpetrators, and half of them knew the bully from school. Both in-school and online bullying experiences were independently associated with increased social anxiety. Ninety percent of the sample reported they do not tell an adult about cyberbullying, and only a minority of participants had used digital tools to prevent online incidents. CONCLUSIONS The findings have implications for (1) school policies about cyberbullying, (2) parent education about the risks associated with online communication, and (3) youth advice regarding strategies to prevent and deal with cyberbullying incidents.

Self-Blame and Peer Victimization in Middle School: An Attributional Analysis.

Sandra Graham; Jaana Juvonen

Relations between characterological versus behavioral self-blaming attributions for victimization and maladjustment were examined in middle school students. Respondents completed a questionnaire that assessed self-perceptions of victim status, attributions for hypothetical incidents of victimization, and feelings of loneliness, social anxiety, and low self-worth. They also completed peer nomination procedures measuring perceptions of victimization in others, as well as peer acceptance and rejection. Self-perceived victimization was associated with characterological self-blame, loneliness, anxiety, and low self-worth. Peer-perceived victimization, in contrast, was related to acceptance and rejection. The data suggest that self-views are more predictive of the intrapersonal consequences of victimization (loneliness, anxiety, low self-worth), whereas peer views are more predictive of interpersonal consequences (peer acceptance and rejection).

Internet Use and Well‐Being in Adolescence

Elisheva F. Gross; Jaana Juvonen; Shelly L. Gable

Previous research suggests that Internet use may be associated with decreases in well-being among adolescents. However, there has been little investigation of the relationship between well-being and social aspects of Internet use. In the present study, 130 7th graders from a middle-class public school in California completed dispositional measures of well-being, and on three subsequent evenings they responded to questions regarding their Internet use (including detailed logs of instant messages) and daily well-being. Time spent on-line was not associated with dispositional or daily well-being. However, as suggested by intimacy theory, the closeness of instant message communication partners was associated with daily social anxiety and loneliness in school, above and beyond the contribution of dispositional measures.

Sticks and Stones May Break My Bones, but Names Will Make Me Feel Sick: The Psychosocial, Somatic, and Scholastic Consequences of Peer Harassment

Adrienne Nishina; Jaana Juvonen; Melissa R. Witkow

This study examined associations among peer victimization, psychosocial problems, physical symptoms, and school functioning across the 1st year in middle school. An ethnically diverse sample of urban 6th graders (N = 1,526) reported on their perceptions of peer victimization, psychosocial adjustment, and physical symptoms during fall and spring. Objective measures of school functioning (i.e., grade point average and absences) were also collected. In Model 1, peer victimization in the fall was associated with spring psychosocial maladjustment and physical symptoms, which in turn predicted poor spring school functioning. Model 2 suggested that psychosocial difficulties increase the risk of victimization, although physical symptoms did not predict victimization. No sex or ethnic group (African American, Asian, European American, and Latino) differences were found in the model structure or the strength of the path coefficients for either model, suggesting that the process is the same for boys and girls and students from different ethnic groups.

Ethnicity, Peer Harassment, and Adjustment in Middle School: An Exploratory Study

Sandra Graham; Jaana Juvonen

In an urban middle school, African American (n = 116), Latino (n = 118), and students from four other ethnic groups (labeled multiethnic, n = 172) completed nomination procedures that identified classmates who were perceived as aggressive or as victims of peer harassment. Peer acceptance and rejection also were measured by nomination procedures, and participants reported their self-perceived loneliness, social anxiety, and global self-esteem. Compared to Latino and multiethnic respondents, more African American students were nominated as aggressive, and fewer were nominated as victims of harassment. However, African American harassment victims reported more loneliness and lower self-esteem than did harassment victims in the other ethnic groups, and they were more rejected by peers. The data were interpreted as evidence that deviations from normative perceptions of a person’s group (i.e., being a victim of harassment when the perceived group norm is aggressiveness) are particularly detrimental to psychological and social adjustment.

Bullying Experiences and Compromised Academic Performance Across Middle School Grades

Jaana Juvonen; Yueyan Wang; Guadalupe Espinoza

The goal of the study was to examine whether bullying experiences are associated with lower academic performance across middle school among urban students.The ethnically diverse sample was drawn from a longitudinal study of 2,300 sixth graders (44% Latino, 26% African American, 10% Asian, 10% White, and 10% mixed) from 11 public middle schools. Results of multilevel models (MLMs) showed that grade point averages and teacher-rated academic engagement were each predicted by both self-perceptions of victimization and peer nominations of victim reputation, controlling for demographic and school-level differences as well as overall declines in academic performance over time. Further MLM analyses suggested that most of the victimization effect was due to between-subject differences, as opposed to within-subject fluctuations, in victimization over time. The results of the study suggest that peer victimization cannot be ignored when trying to improve educational outcomes in urban middle schools.

Bullying in schools: The power of bullies and the plight of victims

Jaana Juvonen; Sandra Graham

Bullying is a pervasive problem affecting school-age children. Reviewing the latest findings on bullying perpetration and victimization, we highlight the social dominance function of bullying, the inflated self-views of bullies, and the effects of their behaviors on victims. Illuminating the plight of the victim, we review evidence on the cyclical processes between the risk factors and consequences of victimization and the mechanisms that can account for elevated emotional distress and health problems. Placing bullying in context, we consider the unique features of electronic communication that give rise to cyberbullying and the specific characteristics of schools that affect the rates and consequences of victimization. We then offer a critique of the main intervention approaches designed to reduce school bullying and its harmful effects. Finally, we discuss future directions that underscore the need to consider victimization a social stigma, conduct longitudinal research on protective factors, identify school context factors that shape the experience of victimization, and take a more nuanced approach to school-based interventions.

Beyond the Individual: The Impact of Ethnic Context and Classroom Behavioral Norms on Victims' Adjustment.

Amy Bellmore; Melissa R. Witkow; Sandra Graham; Jaana Juvonen

With a sample of 1,630 sixth-grade students from 77 classrooms, the authors used hierarchical linear modeling to examine how ethnicity within context and classroom social disorder influenced the association between peer victimization and social-psychological adjustment (loneliness and social anxiety). Victimized students in classrooms where many classmates shared their ethnicity reported feeling the most loneliness and social anxiety. Additionally, classroom-level social disorder served as a moderator such that the association between victimization and anxiety was stronger in classrooms with low social disorder. Both findings were interpreted as evidence that problem behavior deviating from what is perceived as normative in a particular context heightens maladjustment. The authors discuss implications for studying ethnicity and classroom behavioral norms as context variables in peer relations.

What Does It Take to Stand Up for the Victim of Bullying?: The Interplay Between Personal and Social Factors

Virpi Pöyhönen; Jaana Juvonen; Christina Salmivalli

The present study focused on the role of cognitive, emotional, and interpersonal factors in predicting defending of bullied peer. Specifically, the degree to which peer status moderates the effects of emotional and cognitive factors on defending behavior was tested. The sample included 489 students (257 girls) from grades 4 (mean age, 10.6 years) and 8 (mean age, 14.6 years) in Finland. The reputation of being a defender of victimized classmates was associated with a stronger sense of self-efficacy for defending and greater social status within the peer group. Moreover, perceived popularity moderated the effects of both self-efficacy and affective empathy on having a reputation of a defender. The findings are discussed in terms of their implications for interventions designed to reduce bullying.

Reforming Middle Schools: Focus on Continuity, Social Connectedness, and Engagement

Jaana Juvonen

This article provides a brief historical context and analysis of current middle school reform efforts to promote student engagement by facilitating social relationships. International comparisons of perceived social climate are presented to assess whether sense of belonging and support are lacking in American schools. Research documenting associations between student engagement and relationships with teachers and fellow students, in turn, sheds light on when and why social connectedness matters. The article concludes with discussion of future reform goals and alternative strategies to foster student engagement by making middle grades more socially supportive.
