Violence in childhood-onset schizophrenia Open Access

Violence is elevated in older adolescents and adults with schizophrenia; however, little is known about younger children. This report focuses on rates of violence in younger children with schizophrenic-spectrum illnesses. A retrospective review of structured diagnostic interviews from a case series of 81 children, ages 4-15 years of age, with childhood onset of schizophrenic-spectrum illness is reported. Seventy-two percent of children had a history of violent behavior, including 25 children (31%) with a history of severe violence. Of those with a history of violence, 60% had a least one episode of violence that did not appear to be in response to an external stimulus (internally driven violence). There was no significant impact of age or gender. For many children, these internally driven violent episodes were rare and unpredictable, but severe. Similar to what is found in adolescents and adults, violence is common in children with schizophrenic-spectrum illnesses. General violence prevention strategies combined with early identification and treatment of childhood psychotic illnesses may decrease the morbidity associated with childhood psychotic violence.
