The aim of the present study was to examine how the cyberbullying status (not involved, cyber-victim only, cyberbully only, cyber-victim and bully) is related to the mental health of the adolescents when controlled for traditional bullying experience. We also examined the potential moderator sex on the relationship between cyberbullying status and mental health. Univariate analyses of variance were conducted to predict mental health problems using the Strength and Difficulties Questionnaire total difficulties score and its five scales. The model consisted of five predictors in addition to an interaction term between cyberbully status and sex. Of the 2,117 adolescents, 50% were girls. The vast majority did not have any cyberbullying experience (87%), 9% of the adolescents were cyber-victims only, 1% were cyberbullies only and 3% were both cyber-victims and bullies. Overall, girl's mental health seems to be more compromised when exposed to or involved in cyberbullying than boys mental health. In general, adolescents who are not only cyberbullies and cyber-victims, but also cyber-victims only had a worse mental health compared to adolescents without cyberbullying experience. Being exposed to cyberbullying is a unique contributor to mental health problems. Preventing cyberbullying is therefore important. Especially girl's mental health seems to be negatively affected when exposed to cyberbullying.
