Although the majority of students disapprove of aggressive behavior in school, only some of them intervene when witnessing aggression between their classmates. This study examines how bystanders might be activated to support the victims of aggression in school. The effectiveness of a Bystander Intervention Training for students, implemented via teachers, was evaluated. Data from 22 training and 26 control classes were collected at three occasions and analyzed using multivariate multilevel analyses. The primary evaluation criterion was the change in frequencies of aggression and active vs. passive bystander behavior. The training reduced passive bystander behavior and victimization over time. Training effects were stronger for classes with high implementation quality. Recommendations for the implementation of the training will be discussed. [less ▲]

Based on the assumptions of social cognitive theory and self-regulation theory, the present study aimed at exploring psychosocial factors in self-care of diabetes (Edgar & Skinner, 2003; Iannotti et al., 2006; Nouwen et al., 2009). The study sample comprised N 1⁄4 99 patients with type 1 diabetes aged between 12 and 39 years. Participants completed the diabetes self-efficacy scale, the brief illness perceptions questionnaire, the WHO-five index and the summary of diabetes self-care activities scale. Results showed that illness perceptions (i.e. perceived consequences (r1⁄4􏰆0.28), personal control (r1⁄40.24), treatment control (r1⁄40.27), compre- hension (r1⁄40.27) and emotional response (r1⁄40.27)), as well as well-being (r1⁄40.42) and perceived diabetes self-efficacy (r 1⁄4 0.55) were significantly correlated with self-care. Furthermore, stepwise regression analyses elucidated self-efficacy (􏰈1⁄40.44) to be the most powerful predictor of self-care, as illness perceptions and well-being became non significant when introducing self-efficacy. Moreover, self-efficacy completely mediated the effect of well- being on self-care (Sobel t 1⁄4 3.74, p50.01). As for clinical implications of these results, it can be suggested that a stronger emphasise should be given on fostering patients’ confidence in their ability to effectively manage their diabetes.

Despite significant overlaps between victim status in traditional forms of bullying and cyberbullying, and qualitative results about self-reported reasons for cyberbullying, the role of revenge and retaliation as a motive to engage in acts of cyberbullying has not yet been examined systematically. As a first step, this study investigates whether and to what extent traditional victims, when they become cyberbullies, actually choose their former (traditional) perpetrators as targets of their own cyberbullying behavior. Furthermore, the impact of individual differences in relevant traits, such as vengefulness and justice sensitivity, on the choice of cybervictims is examined. Data from 473 students were collected via an online survey. Of these, 149 were identified as traditional victims/cyberbullies. Results show that traditionally bullied students indeed tend to choose their former perpetrators as cybervictims, and that individual differences play a role in the choice of their victims. Implications for further research, as well as for interventions and prevention programmes, are discussed. [less ▲]

L’étude présente la validation française d’une échelle allemande (AERZ) [Diagnostica 49 (2003) 97–109, révisée Eur J Pers (2009)], évaluant la régulation de la colère. Cet instrument mesure sept réactions et sept buts liés à la colère (RBC). L’apport principal de cette échelle est la mise en évidence des dimensions réactionnelles et intentionnelles lors de la régulation de la colère. Au-delà d’un panel de réactions fonctionnelles, voire dysfonctionnelles, la RBC revient sur les buts offensifs et défensifs associés à l’émotion de la colère. La version française adaptée a été administrée à un échantillon d’étudiants (n = 184). La structure factorielle de la version originale a en grande partie pu être retrouvée avec des consistances internes satisfaisantes pour les différentes dimensions. Globalement, les résultats obtenus attestent la validité, la fidélité et la sensibilité des construits mesurés par la RBC. Cette validation offre, en particulier dans le contexte français, un inventaire multidimensionnel permettant d’étudier les réactions et les buts liés à la colère, par exemple en testant l’efficacité d’interventions de régulation de la colère ou en tant que diagnostic.

The motion detection technology used in innovative game controlling devices like the Nintendo Wii-Remote® provides experiences of realistic and immersive game play. In the present study (N=62) it was tested whether this technology may also provoke stronger aggression-related effects than standard forms of interaction (i.e., keyboard and mouse). With the aid of a gesture recognition algorithm, a violent action role-playing game was developed to compare different modes of interaction within an otherwise identical game environment. In the Embodied Gestures condition participants performed realistic striking movements that caused the virtual character to attack and kill other in-game characters with a club or sword. In the Standard Interaction condition attacks resulted from simple mouse clicks. After the game session, participants showed a similar increase in negative feelings in both groups. When provided with ambiguous scenarios, however, participants in the Embodied Gestures condition tended to show more hostile cognitions (i.e., anger) than the Standard Interaction group. Results further corroborate the complexity of aggression-related effects in violent video games, especially with respect to situational factors like realistic game controls. [less ▲]
