The long-term risk of suicide after a first episode of psychosis is unknown, because previous studies have often been based on prevalence cohorts, have been biased to more severely ill, hospitalised patients, have extrapolated from a short follow-up time, and have made a distinction between schizophrenia and other psychoses. The aim of this study was to determine the epidemiology of suicide in a clinically representative, retrospective inception cohort of patients with a first episode of psychosis.
