Violent outcomes in first-episode psychosis: a clinical cohort study

Aim: Violence risk is an important part of a comprehensive clinical assessment in first‐episode psychosis. This study addresses limitations of previous violent outcome research in first‐episode psychosis, which has typically investigated selected cohorts or been restricted to violence occurring prior to service contact, with limited use of police data.Methods: For individuals consecutively assessed by Early Intervention in Psychosis (EIP) services in two UK regions (n = 177), violent outcomes in the subsequent 12‐months were collected using electronic patient records, supplemented by police data.Results: Of individuals accepted by EIP services (n = 109), electronic medical records indicated around 1 in 4 (n = 28, 25.7%) perpetrated any physical violence, and 1 in 10 (n = 10, 9.2%) were arrested or charged for violent offences in the 12‐months after first contact. Police data on all individuals assessed (n = 177) reported 1 in 7 (n = 26, 14.7%) were arrested or charged for violent offences in the 12‐months after first contact.Conclusions: EIP services should consider integrating multi‐agency sources of data to evaluate violent outcomes. The potential role of violence risk management should be further examined
