3,600 children from the Avon Longitudinal Study of Parents and Children completed a detailed questionnaire on sibling bullying at twelve years of age, and then subsequently filled out a standardized clinical examination assessing psychotic symptoms when they were eighteen years old.

Summary: Researchers have discovered a link between sibling bullying and an increased risk of developing a psychiatric disorder during early adulthood. The study reports those who are bullied by siblings are three times more likely to be diagnosed with disorders, such as schizophrenia, by the time they reach adulthood. Those who are bullied at home and at school are four times more likely to develop psychiatric disorders, researchers note.
