Persistence of effectiveness of cognitive remediation interventions in schizophrenia: A 1-year follow-up study.

Cognitive remediation interventions are effective in patients with schizophrenia, but the durability of their effects is still under debate. This study aimed to investigate the 1-year persistence of the effectiveness of cognitive remediation.Patients with schizophrenia treated with cognitive remediation or usual rehabilitation were reassessed with clinical, neuropsychological and functional measures 1year after cognitive remediation.At the 1-year follow-up, the advantages of cognitive remediation remained significant for clinical variables and specific cognitive domains. Functional measures showed increasing improvement at follow-up.The study suggests that the effectiveness of cognitive remediation in schizophrenia persists after 1year.
