ABSTRACT

BACKGROUND: Psychotic disorders are frequently associated with a public perception of dangerousness and belligerence. This situation has contributed to the social stigmatisation of people with severe mental illness and the resulting discrimination that this scenario entails. Despite efforts to demystify such disorders, the association between violent behaviour and psychosis remains unclear.

AIMS: To explore the incidence of the main types of violent offences in a cohort of patients presenting with first-episode psychosis (FEP).

METHOD: Participants were recruited from the First Episode Psychosis Intervention Program (CRUPEP) cohort between 2009 and 2016. The main clinical variables were collected, including medical-forensic records of participants registered at the Basque Institute of Forensic Medicine (BIFM), to identify any violent acts in which participants were involved, either as victims or as offenders.

RESULTS: Overall, 79.5% (n = 182) of the participants had no record of violent crime or offence recorded in the BIFM. Annual crime rates for the 2009-2016 period show a decreasing trend in both the general population (IRR = 0.981, 95% CI 0.978-0.983, P < 0.001) and in the FEP group (IRR = 0.019, 95% CI 0.012-0.028, P < 0.001); this pattern is more pronounced in the FEP group. Victimisation accounted for the vast majority of reported incidents; nevertheless, participants who had committed violent offences were mostly involved in intrafamily violence.

CONCLUSIONS: Individuals with FEP were not involved in a higher number of crimes than the general population. The types of violent acts committed by people with FEP were heterogeneous, with extreme violence being particularly uncommon.
