The association between mental health problems and traditional bullying is well known, whereas the strength of the association in cyberbullying is less known. This study aimed to compare the association between mutually exclusive groups of bullying involvement and psychosomatic problems as measured by the PsychoSomatic Problems scale. The sample comprised 3820 students (13-16 years old) in Sweden. The results indicate an association between bullying and psychosomatic problems, regardless of type of bullying involvement. No statistically significant differences in psychosomatic problems were found between cyberbullying and traditional bullying, either for victims or for bullies. The results do not confirm the hypothesis that the association between bullying and mental health is stronger for cyberbullying than for traditional bullying. Another important finding is that cyberbullies seem as likely as cybervictims to be at risk for mental health problems. (Contains 4 tables.)
