Everyday action planning in schizophrenia

Planning of everyday tasks was examined in 48 inpatients with schizophrenia and 26 healthy controls. Participants were administered the Naturalistic Action Test, which requires completion of three everyday tasks (e.g., make toast and coffee). Planning variables, including planning behaviours (e.g., gathering items before engaging in a subtask) and planning time (e.g., period between task instructions and first action) were coded to evaluate forward thinking in these tasks. Results showed that planning variables were reliably coded. Controls demonstrated more planning behaviours than participants with schizophrenia; however, this difference was accounted for by education. People with schizophrenia spent significantly less time planning when planning time was analysed as a proportion of the total time on tasks. Planning variables were related to the ability to accomplish everyday task steps and to perform everyday task steps accurately. Together these findings suggest that rehabilitation strategies that emphasise both planning time and planning behaviours may facilitate everyday functioning in people with schizophrenia.
