Although a number of studies have found prospective memory (PM) impairment in patients with schizophrenia, very little is known about the PM performance in non-psychotic relatives of these patients. The current study aimed to explore the PM performance in non-psychotic first-degree relatives of these patients. Two groups of participants (26 non-psychotic first-degree relatives of schizophrenia patients and 26 healthy comparison participants) were administered three PM tasks (time-, event-, and activity-based) and a set of neurocognitive tests. Results showed that the relatives performed significantly worse than the comparisons on most indices of the PM tasks, with a similar pattern of impairment found in other neurocognitive measures. Together with findings from previous studies, results of the current study suggest that PM may be a potential endophenotype for schizophrenia. © 2009 Elsevier Ltd.
