People who were bullied by siblings during childhood are up to three times more likely to develop psychotic disorders such as schizophrenia in early adulthood, according to new research by the University of Warwick.
Led by Professor Dieter Wolke (senior author) at Warwick's Department of Psychology, this is the first study to explore the relationship between sibling bullying and the development of psychotic disorders.
Almost 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.
