Fights among siblings damage mental health

Around 3500 children aged 10–17, or the parents of children aged 0–9, were interviewed by telephone about instances of peer and sibling aggression, depression, anger and anxiety.

The results showed sibling aggression in the form of physical assault with or without a weapon or injury, and property and psychological assault, were all associated with greater mental distress.

Children who experiencing several types of sibling or peer aggression reported greater mental distress.
