title: Prospective Memory Performance in Persons With Schizophrenia and Bipolar Disorder and Healthy Persons.
abstract: OBJECTIVE
  There is a paucity of studies comparing prospective memory (PM) impairment between persons with schizophrenia and bipolar disorder. The aim of this study was to directly compare PM performances of these two groups and healthy controls.
  
  
  METHODS
  A total of 44 persons with schizophrenia and 76 with bipolar disorder, and 44 healthy controls formed the study sample.
  
  
  RESULTS
  Patients were found to be impaired in PM relative to controls and the two patient groups showed similar level of PM performance after controlling confounding sociodemographic and clinical variables.
  
  
  CONCLUSIONS
  The findings add to the evidence concerning the neurocognitive similarity between cohorts of schizophrenia and bipolar disorder with respect to PM. Rehabilitative effort in PM remedies for both patient groups is warranted.
