|
Objectives：The purpose of this study was to investigate the differences in forensic demographic characteristics, interpersonal problems and personality disorder between early and late onset criminal patients with schizophrenia.
Methods：The participants included 187 inpatients with schizophrenia who had committed crimes. They filled out the Korean Inventory of Interpersonal Problem Personality Disorder Scales and Psychopathic Personality Inventory-Revised. They were divided into early onset group and late onset group according to onset age of schizophrenia at 26 years old(under 26 versus 26 and older) and forensic demographic characteristics, interpersonal problem and personality disorders including psychopathy were compared between two groups.
Results：There were no differences in gender, education years and family history between the two groups. Early onset group was associated with lower age, earlier onset of age and earlier age at the time of the crime. Duration from onset to diagnosis was not different between the two groups. Duration from onset to crime and after diagnosis to crime was shorter in late onset group. There were no differences between the two groups in the interpersonal problems, personality disorder and psychopathic personality evaluation.
Conclusion：These results suggested that there may be forensic demographic differences related to crime between early and later onset schizophrenia. Psychiatrists should consider the age at onset of schizophrenia when assessing the risk of violence in patients with schizophrenia. In the future. it will be needed other study of age classification such as admixture analysis.
