The outcome of early intervention in first episode psychosis

Abstract

The last 20 years have seen an increased focus on early intervention in psychotic disorders in research and clinical practice. Interventions have typically aimed at either reducing the duration of untreated psychosis (DUP), or developing specialized treatment facilities for patients with first episode psychosis (FEP). This review presents an overview of the most important trials and meta-analytic evidence within this field. The possibilities for reducing DUP and elements included in specialized early intervention treatment are discussed. Further, it examines long-term outcomes of early interventions and results from prolonged early intervention trials. Lastly, it analyses possible interactions between DUP and specialized early intervention treatment. In conclusion, both elements appear necessary in order to develop an integrated service that can provide the optimal treatment for patients with FEP. The aim of this article is to provide an overview over the most important trials and evidence regarding the outcome of early intervention in first episode psychosis.
