--- - |2+ Abstract Background Few studies have examined alexithymia, the inability to identify or describe one's emotions, as a possible correlate of bullying. Aims To investigate whether there are differences among 12–18 year‐olds in capacity for identifying and/or describing own emotions between traditional bullies, cyber bullies, combined bullies, and nonbullies. Methods Data from self‐report questionnaires completed by 897 female and 652 male 12–18 year‐olds (mean 14.5 years, standard deviation 1.68) from Germany and Thailand were analysed using analysis of covariance. Results Young people who reported never having bullied others scored lower on the alexithymia scale than traditional, cyber, or combined bullies. There were no differences between traditional and cyber bullies on this measure, but those who operated in both ways had significantly higher alexithymia scores compared with those who bullied in just one modality. Conclusion Alexithymia is thus likely to be an important factor to consider in prevention and treatment of bullying. We recommend that prevention programmes include elements to help identify and describe one's own emotions, providing additional support, and “training” if alexithymia is identified. When young people use cyber techniques and traditional bullying methods, it seems likely that they will have greatest need in this respect. - 'Criminal Behaviour and Mental Health, Volume 28, Issue 5, Page 409-413, October 2018.
