EFFECTS OF BRAIN INJURY AND AGE ON PROSPECTIVE MEMORY SELF-RATING ANDPERFORMANCE

The purposes of this study were (1) to assess internal consistency and test-retest reliability of the Prospective Memory Questionnaire (PMQ) developed by Hannon and associates; (2) to compare PMQ self-ratings o f adults with brain injury versus younger and older noninjured adults; (3) to develop short-term and long-term tasks for measuring actual pr ospective memory performance; and (4) to study the relationship betwee n scores on the PMQ and the prospective memory tasks. Internal consist ency of the PMQ was .92 and test-retest reliability was .88. Groups di ffered significantly on only one PMQ subscale. Actual prospective memo ry performance was significantly worse for adults with brain injury an d older adults than for younger adults on two of the three sets of sum mary measures. PMQ self-ratings were significantly but weakly correlat ed with short-term task performance, but not with long-term task perfo rmance. Implications of the findings for assessment and treatment of p rospective memory impairment are discussed.
