Abstract
BackgroundThree out of four first-episode psychosis (FEP) patients achieve clinical remission following treatment. Unfortunately, functional recovery lags behind symptomatic remission, and many individuals with FEP remain socially isolated with poor functional outcomes. AimsTo systematically compile and analyse predictors of functional recovery in FEP. MethodSystematic review and meta-analysis of peer-reviewed, longitudinal studies reporting predictors of functioning, with a minimum 12-month follow-up and at least 80% of participants diagnosed with FEP. ResultsOut of 2205 citations, 274 articles were retrieved for detailed evaluation resulting in 50 eligible studies (N=6669). Sociodemographic, clinical, physical and neuroimaging variables had little impact on long-term functioning. Conversely duration of untreated psychosis (DUP), most cognitive variables, and concurrent remission of positive and negative symptoms were independently related to functional recovery. ConclusionsThese findings strongly support the rationale for early intervention in FEP. Novel treatments targeting cognitive deficits may improve functional outcomes in FEP.
