Abstract
BACKGROUND: Transcultural studies have found lack of insight to be an almost invariable feature of acute and chronic schizophrenia, but its influence on prognosis is unclear. AIMS: To investigate the relationship between insight, psychopathology and outcome of first-episode schizophrenia in Vellore, India. METHOD: Patients with a DSM-IV diagnosis of schizophrenia (n = 131) were assessed prospectively at baseline and at 6-month and 12-month follow-up. Demographic and clinical measures included insight, psychopathology, duration of untreated psychosis (DUP) and social functioning. Linear and logistic regression was used to measure predictors of outcome. RESULTS: Follow-up data were available for 115 patients at 1 year. All achieved remission, half of them with and half without residual symptoms. Changes in psychopathology and insight during the first 6 months and DUP strongly predicted outcome (relapse or functional impairment), controlling for baseline measures. CONCLUSIONS: Outcome of schizophrenia in this setting is driven by early symptomatic improvement and is relatively favourable, in line with other studies from low- and middle-income countries. Early improvement in insight might be a useful clinical guide to future outcome. Reduction of DUP should be a target for intervention.
