Sibling bullying is a type of violence that is prevalent in the lives of most children, but little is known about it, researchers say.

Clemson University psychology professor Robin Kowalski said the phenomenon has been overlooked.

Kowalski and and co-author Jessica Skinner explored the extent to which sibling bullying is viewed to be normal and the perceived differences between victims and perpetrators. They recently published their findings in the Journal of Interpersonal Violence.

The purpose of the study was to profile sibling bullying by examining prevalence rates, the extent to which siblings perceive sibling bullying to be normative and victim-perpetrator differences in perceptions of sibling bullying.

Seventy-five percent of the participants in the study reported being bullied by a sibling and 85 percent reported bullying a sibling.
