AbstractSibling relationships have a significant and lasting impact on children's development. Many siblings experience some occasional conflict, however, up to 40% are exposed to sibling bullying every week, a repeated and harmful form of intra-familial aggression. Evidence on the precursors, relationship with peer bullying, and mental health consequences of sibling bullying are reviewed. Parenting quality and behaviour are the intra-familial factors most strongly related to bullying between siblings. Sibling bullying increases the risk of being involved in peer bullying, and is independently associated with concurrent and early adult emotional problems, including distress, depression and self-harm. The effects appear to be cumulative, with those bullied by both siblings and peers having highly increased emotional problems, likely because they have no safe place to escape from bullying. The link between sibling and peer bullying suggests interventions should start at home. Health professionals should ask about sibling bullying and interventions are needed for families to prevent and reduce the health burden associated with sibling bullying.Bullying in the Family: Sibling Bullying
