Perpetrators of homicide with schizophrenia: sociodemographic characteristics and clinical factors in the eastern region of Turkey.

In this study, we aimed to describe the social and clinical characteristics and offense details in a sample of people with schizophrenia convicted of homicide in the eastern region of Turkey. This study was performed in Elazig Mental Hospital between November 2004 and May 2007. We included 43 men and 6 women with schizophrenia convicted of homicide who were hospitalized in the forensic psychiatry unit for compulsory treatment. Preset data recording forms were used. The first part of the forms contained questions regarding the age, sex, marital status, residence, educational status, and occupation of the patients. The second part of the forms included questions about some clinical features of patients with schizophrenia: the presence of schizophrenia in any family member, duration of the disease, subtype of schizophrenia, previous contact with mental health services, types of antipsychotics (first and last drug used), and adherence to antipsychotic medication. The third part of the forms dealt with alcohol-substance abuse and features of the victim (sex of the victim and whether the victim was a stranger, partner, or an ex-partner in the family or an acquaintance). The mean +/- SD age of our patients was 36.98 +/- 10.07 years, and 55.1% of the patients were unmarried. In our sample, 42.9% of the patients were primary school graduates and 75.5% were unemployed. Of the perpetrators, 14.3% never had contact with mental health services. However, 85.7% of patients had previous contact with mental health services. We found that 85.7% of the patients were paranoid subtype and 85.7% were not using their medication regularly and that treatment compliance was considerably low. We found that haloperidol and trifluoperazine were the most preferred antipsychotic drugs, particularly being the first drugs used during treatment (haloperidol, 71.4%; trifluoperazine, 10.2%) and the last antipsychotics used before the offence (haloperidol, 46.9%; trifluoperazine, 20.4%). In 38.8% of cases, schizophrenia was present in the first-degree relatives. We also found that 69.4% of victims were one of the family members. In our sample, 24.5% of patients were using alcohol and 4.1% were using cannabis. It is plausible that rendering more effective communication might allow earlier intervention for unrecognized and possibly unrecognizable risk factors of homicidal acts in people with schizophrenia.
