Victimisation in adults with severe mental illness: prevalence and risk factors.

BACKGROUND: Patients with a severe mental illness (SMI) are more likely to experience victimisation than the general population. AIMS: To examine the prevalence of victimisation in people with SMI, and the relationship between symptoms, treatment facility and indices of substance use/misuse and perpetration, in comparison with the general population.
METHOD: Victimisation was assessed among both randomly selected patients with SMI (n = 216) and the general population (n = 10 865).
RESULTS: Compared with the general population, a high prevalence of violent victimisation was found among the SMI group (22.7% v. 8.5%). Compared with out-patients and patients in a sheltered housing facility, in-patients were most often victimised (violent crimes: 35.3%; property crimes: 47.1%). Risk factors among the SMI group for violent victimisation included young age and disorganisation, and risk factors for property crimes included being an in-patient, disorganisation and cannabis use. The SMI group were most often assaulted by someone they knew.
CONCLUSIONS: Caregivers should be aware that patients with SMI are at risk of violent victimisation. Interventions need to be developed to reduce this vulnerability. © The Royal College of Psychiatrists 2015.
