There is considerable debate over whether cyberbullying is just another form of bullying, or whether it is a problem distinct enough to require specific intervention. One way to explore this issue is to analyze whether programs designed to prevent traditional bullying help prevent cyberbullying, and whether programs designed to prevent cyberbullying prevent traditional bullying. The main goal of the current study was to analyze the spillover effects of the cyberbullying prevention program Media Heroes (Medienhelden) on traditional bullying. Media Heroes promotes empathy, knowledge of risks and consequences, and strategies that allow bystanders to defend victims from cyberbullying. Mixed ANOVAs were conducted comparing pretest and post-test (6 months after intervention) measures of 722 students (ages 11-17) assigned to a long (15 sessions) intervention, a short (1 day) intervention, and a control group. In addition to confirming the previously reported effects on cyberbullying, Media Heroes was found to reduce traditional bullying. Effects were larger for the long-version of the program than for the short 1-day version. No effects were found on victimization by either cyberbullying or traditional bullying. Strategies to complement traditional and cyberbullying prevention efforts are discussed. Aggr. Behav. 42:157-165, 2016. © 2016 Wiley Periodicals, Inc.

Adjusting nomination‐based sociometric and peer assessment scores for biases due to variations in group size has been a long‐standing concern for peer relations researchers. The techniques that have been typically used to make these adjustments (e.g., proportion and standardized scores) are known to have fundamental problems that limit their utility. This study introduces a regression‐based procedure that adjusts nomination‐based scores for variations in group size and compares it with the standardization and proportion procedures. Analyses were conducted on sociometric and peer assessment scores of 1594 fourth, fifth, and sixth graders from 63 classrooms. The advantages of the regression‐based procedure over standardization and proportion transformations are outlined. Implications for the accuracy and validity of nomination‐based measures and the research findings based on them are discussed.

Classrooms in Peace (Aulas en Paz) is an elementary school-based multicomponent program for prevention of aggression and promotion of peaceful relationships. Inspired by international programs and socio-emotional research, it includes (1) a classroom universal curriculum, (2) parent workshops and home visits to parents of the 10% most aggressive children, and (3) extracurricular peer groups of two aggressive and four prosocial children. Activities seek to promote socio-emotional competencies such as empathy, anger management, creative generation of alternatives, and assertiveness. A 2-year quasi-experimental evaluation was conducted with 1154 students from 55 classrooms of seven public schools located in neighborhoods with the presence of youth gangs, drug cartels, and high levels of community violence in two Colombian cities. Despite several implementation (e.g., about half of the activities were not implemented) and evaluation (e.g., randomization problems, large number of missing data, and changes between treatment and control groups) challenges, positive results were found in prosocial behavior and in reduction of aggressive behavior, according to teacher reports, and in assertiveness and reduction of verbal victimization, according to student reports. Furthermore, implementation cost (25 US dollars per student per year) was very low compared to other programs in developed countries. This study shows that the Classrooms in Peace program has an important potential to generate positive results and highlights the challenges of implementing and evaluating prevention programs in highly violent environments.

Contextual differences in the association between different forms of aggressive behavior and victimization were studied with a sample of 197 boys and 149 girls from mixed-sex schools and in 336 girls from all-girl schools ( M = 10.21 years of age) in two cities in Colombia. Results showed that boys generally engage in more physical than relational aggression, whereas girls engage in more relational than physical aggression. Among boys, the association between aggression and victimization was significant only for the measure of relational aggression, whereas, for girls, victimization was significantly correlated only with physical aggression. This latter association was found to be significantly stronger for girls from the all-girl schools than for the girls from the mixed-sex schools. These findings are discussed in terms of how mixed-sex and same-sex groups, as different forms of peer context, affect the social dynamics related to the association between aggression and victimization.
