The transition from physical sibling abuse to bullying perpetration through trait anger: A longitudinal study.

Objectives: Experiencing physical sibling abuse is a form of family violence that is common but understudied. While it is often perceived as a normative aspect of sibling relationships, there are apparent behavioral consequences. The current study aims to advance the literature by utilizing the displaced aggression model and I theory to longitudinally examine trait anger as a pathway linking physical sibling abuse to bullying perpetration.
