Event-based prospective memory in schizophrenia.

Although memory deficits have been well documented in schizophrenia, so far, there is dearth of literature about prospective memory (PM), that is memory for future events, in this disorder. The present study investigated event-based PM in schizophrenia. Additionally, the relationship of event-based PM with clinical variables of schizophrenia was also assessed. Task incorporating event-based prospective memory was administered on 42 schizophrenia patients and 42 nonpsychiatric comparison subjects. Patients with schizophrenia were additionally rated on The Scale for the Assessment of Positive Symptoms, The Scale for the Assessment of Negative Symptoms and The Brief Psychiatric Rating Scale. Results showed schizophrenia patients to have poor event-based prospective memory. However, no significant correlation was observed between the clinical variables and PM.
