• The aim of the present study was to investigate the potential moderating role of online disinhibition in the associations between adolescents' callous-unemotional traits (callousness, uncaring, unemotional) and anonymous and non-anonymous cyberbullying. To this end, 1047 (49.2% female) 7th and 8th graders completed questionnaires on their face-to-face bullying, cyberbullying, callous-unemotional traits, and online disinhibition. The findings revealed that increases in uncaring were more associated with self-reported non-anonymous and anonymous cyberbullying at higher levels of online disinhibition. The findings are discussed in the context of the characteristics associated with callous-unemotional traits, and how these characteristics increase adolescents' risk of cyberbullying perpetration. Recommendations are made for tailoring intervention programs to consider adolescents' personality traits.
