Cyberbullying has been portrayed as a rising ‘epidemic’ amongst children and adolescents. But does it create many new victims beyond those already bullied with traditional means (physical, relational)? Our aim was to determine whether cyberbullying creates uniquely new victims, and whether it has similar impact upon psychological and behavioral outcomes for adolescents, beyond those experienced by traditional victims. This study assessed 2745 pupils, aged 11–16, from UK secondary schools. Pupils completed an electronic survey that measured bullying involvement, self-esteem and behavioral problems. Twenty-nine percent reported being bullied but only 1% of adolescents were pure cyber-victims (i.e., not also bullied traditionally). Compared to direct or relational victims, cyber-victimization had similar negative effects on behavior (z = −0.41) and self-esteem (z = −0.22) compared to those not involved in bullying. However, those bullied by multiple means (poly-victims) had the most difficulties with behavior (z = −0.94) and lowest self-esteem (z = −0.78). Cyberbullying creates few new victims, but is mainly a new tool to harm victims already bullied by traditional means. Cyberbullying extends the reach of bullying beyond the school gate. Intervention strategies against cyberbullying may need to include approaches against traditional bullying and its root causes to be successful.Electronic supplementary materialThe online version of this article (doi:10.1007/s00787-017-0954-6) contains supplementary material, which is available to authorized users.

LMPT infants are at significantly increased risk for positive autistic screen. An M-CHAT follow-up interview is essential as screening for autism spectrum disorders is especially confounded in preterm populations. Infants with false positive screens are at risk for cognitive and behavioral problems.

Bullying victimization has commonly been associated with deficiencies in social information processing (SIP). In contrast, findings regarding bullying perpetration are mixed, with some researchers claiming that bullies may have superior SIP abilities than victimized or uninvolved youth. This study investigated the effects of bullying and victimization on early SIP; specifically the recognition and interpretation of social information. In stage 1, 2,782 adolescents (11-16 years) were screened for bullying involvement, and in stage 2, 723 of these participants (mean age = 13.95) were assessed on measures of emotion recognition, hostile attribution bias, and characterological self-blame (CSB). No associations between bullying and early SIP were found. In contrast, victimization was associated with more hostile attribution bias and CSB attributions. Girls performed better than boys on the emotion recognition task while boys showed greater hostile attribution biases. No interaction effects of bullying or victimization with gender were found. Follow-up categorical analyses that considered pure victims versus victims who also bullied (bully-victims) on SIP, found a similar pattern of findings. These findings suggest that those who purely bully others are neither superior nor deficient in the early stages of SIP. Victimized adolescents, however, show biases in their interpretations of social situations and the intentions of others. These biases may lead to maladaptive responses and may increase risk for further victimization by peers.
