Abstract

This study aimed to understand the demographic, clinical and criminological characteristics of Chinese homicide offenders with schizophrenia from a gender-based perspective. Information on all homicide offenders with schizophrenia who received forensic psychiatric assessment between 2010 and 2016 in Hunan Province, China, was systematically retrieved (n = 669). Gender differences in the above characteristics were analyzed, and independent correlates of homicide were explored. The male to female ratio of homicide offenders was about 4:1. Proportionally more males were single, unemployed and younger when committing their first crime than was apparent in females. Male perpetrators were more often influenced by delusions. Females were more likely to target their close family members. For males, living in rural areas and having a family history of mental disorder were positively associated with homicide, while having a criminal history and being unemployed were negatively associated. For females, younger age was positively, while being unmarried and unemployment were negatively associated with homicide. Our results indicate significant gender differences among Chinese homicide offenders with schizophrenia in demographic, clinical and criminological characteristics and in independent correlates of homicide. Further research in this field, especially aims at determining risk factors for crime in this population, should take the gender differences into account.
