title: Associations with violent and homicidal behaviour among men with schizophrenia.
abstract: Objective We aimed to assess the risk factors associated with homicidal behaviour in male patients diagnosed with schizophrenia. Methods In a period of 1 year, male schizophrenia cases between 18-65 years of age (n = 210) were included. The clinical evaluation included the Positive and Negative Syndrome Scale (PANSS) and Overt Aggression Scale (OAS). The patients were divided into three groups in terms of violent behaviour history: (1) homicide group (n = 30), (2) a violent act resulting in serious injury (n = 71), (3) control group (patients without a history of a violent act) (n = 109). Results Lower level of education, rural residence, being unemployed and living alone were found to be significantly more common in patients who had committed a violent act compared to the schizophrenia patients in the control group. In order to explore the predictive value of several factors associated with violent behaviour, a logistic regression model was used, and variables (shorter duration of education, living alone, and lack of insight) significantly predicted the presence of violent behaviour (murder and/or injury) (χ(2)=31.78, df = 12, p = 0.001). Conclusions In order to be able to determine causality of homicidal acts in schizophrenia patients, our significant findings between homicidal violence, non-homicidal violence and the control group would merit further attention and exploration in further studies.
