Correlates of offense recidivism in patients with schizophrenia

Abstract

IntroductionSchizophrenia increases the risk of offending. Recidivism rates are significant. Literature doesn't provide recidivism risk factors specific to patients with schizophrenia independently of the offenses' types. ObjectiveIdentifying recidivism risk factors in schizophrenia patients independently of the offenses' types. MethodsWe conducted a case-control study. All included patients were admitted, at least once, to the forensic psychiatry unit in Razi Hospital between January 1st, 1985 and December 31st, 2014 after a decision of irresponsibility by reason of insanity. All those who reoffended during this period were considered as cases. Univariate and multivariate analyses were performed to identify recidivism risk factors. ResultsWe included 25 cases and 38 controls. Eight recidivism risk factors were identified. Living in poor urban neighborhoods (P = 0.023; OR = 4.86), having been unemployed (P = 0.042; OR = 2.18) and not having lived with the family (P = 0.039; OR = 1.36) after discharge were considered as risk factors. The same applied to alcohol (P = 0.026; OR = 4.89) and cannabis use disorders (P = 0.018; OR = 6.01). A hospitalization shorter than 6 months multiplied the risk by 1.79 (P = 0.046). A combination of conventional antipsychotics (P = 0.023; OR = 4.81) and a poor adherence to treatment (P = 0.001; OR = 10.42) were considered as recidivism risk factors too. ConclusionsAll eight recidivism risk factors are dynamic. This makes recidivism prevention conceivable. Measures involving the patient, the health care system, patients' families, society and the government should be undertaken.
