Association between schizophrenia and violence among Chinese female offenders

Abstract

Little is known about the association between schizophrenia and violence in women in China. This study aimed to examine the association between schizophrenia and violence in Chinese female offenders. Fifty-two schizophrenia patients were identified from the female offenders who received forensic psychiatric assessments in 2011 in Hunan province, China. Using a propensity score matching method, 104 matched controls without psychiatric disorders were selected from female criminals in Hunan province. Violent offences and homicides were verified and recorded. The percentages of violent offences and homicides were significantly higher in female offenders with schizophrenia than in controls (78.8% vs. 30.8%, P < 0.001; 44.2% vs. 18.3%, P = 0.001, respectively). Multivariate logistic regression analyses revealed that diagnosis of schizophrenia, younger age at first offence, living in rural area and a lower education level were independently and positively associated with violent offences, while having a diagnosis of schizophrenia and lower education level were associated with homicides. There appears to be an independent and positive association between schizophrenia and violent offence in Chinese female offenders. Effective preventive approaches on violence in female schizophrenia patients are warranted.

This study found that female patients with constipation is significantly greater than male patients, and some studies said that most of the reports only focus on male patients with less attention to women, but the study found that female patients with schizophrenia have a greater tendency of violence than the general population, and the ratio is higher than male patients, the reason is that female patients are more likely to be violent than male patients Sexual patients have more drug abuse, which also increases the risk of complications in female patients, which is consistent with the results of this study [28] . However, a study in rural China reported that the long-term prognosis of male schizophrenic patients in rural China is worse than that of female patients, which also leads to the fact that male schizophrenic patients in rural China are more likely to have complications than female patients [29] .…”

Correlation Between Violence and Antipsychotic Dosage in Schizophrenia: A Secondary Analysis of The Clinical Antipsychotic Trials for Intervention Effectiveness (CATIE) Dataset

“…Although the incidence of violence in schizophrenia is low, patients with schizophrenia are still at a higher risk of engaging in violent behavior than the general population [1][2][3][4]. Positive symptoms of schizophrenia have been associated with violence [5], and several studies examining the effect of antipsychotics in reducing the risk of violence found that antipsychotic usage reduces violent behavior [5,6].…”
