This study explored cyberbullying, coping resources and coping styles in a sample of 107 10- to 12-year-old Australian primary school students. Approximately 13% of participants reported experiencing single episodes of cyberbullying victimisation, while almost half of the participants (48.6%) reported being repeatedly cyberbullied. Technological responses employed by cyberbullying victims included blocking, deleting, and changing passwords. Those who reported a single episode of cyberbullying had higher levels of self-esteem compared to the never cyberbullied or repeatedly cyberbullied groups, but there were no significant differences in attachment, locus of control, and coping styles. These findings have important implications for teachers, parents, school psychologists, and researchers in terms of defining and operationalising cyberbullying, and developing cyberbullying interventions for primary school children.
