Objective: To determine the prevalence of five forms of abuse/neglect during childhood and adolescence in a group of schizophrenic patients with a history of violence. Methods: Twenty-eight patients hospitalized in a highly secured psychiatric unit were included. Abuse and neglect during patients' growth were evaluated with the childhood trauma questionnaire (CTQ). History of substance abuse (consumption of cannabis, and/or alcohol, and/or heroin, and/or cocaine during the year that preceded the hospitalization), incarceration, and death of a close parent were also collected. Results: We found that 46.4% of patients experienced at least 1 form of abuse and/or neglect during childhood and 21.4% of them had experienced more than 2 forms of abuse and/or neglect. The 2 most frequent forms of neglect and abuse were physical abuse (39.3%) and emotional neglect (17.9%). History of substance abuse was found for cannabis (57.1%), alcohol (57.1%), and cocaine and/or heroin (35.7%). We found that 42.8% of patients had 1 close relative who had died during their growth and that 41.6% of these deaths were violent. Conclusion: It appears important to systematically search for and assess a history of abuse and neglect during growth in schizophrenic patients with a history of violence, in order to offer specific treatments for this group of patients.
