Age- and education-corrected independent normative data for the RBANS in a community dwelling elderly sample.

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS, Randolph, 1998) is likely to become a popular screening instrument for measuring cognitive functioning, particularly in elderly patients. As such, the present study attempted to extend the original normative data by reporting on RBANS performances in a group of 718 community dwelling older adults. Participants were recruited from an outpatient primary care setting, and were assessed for demographic, medical status, functional status, and quality of life information. Utilizing four empirically supported overlapping midpoint age ranges, individual subtest raw scores were converted to age-corrected scaled scores based on their position within a cumulative frequency distribution. These age-corrected scaled scores were also converted into education-corrected scaled scores using the same methodology across four education levels. Independent Index and Total scores were also calculated based on the data from this large elderly sample. These data may considerably advance the clinical utility of the RBANS by allowing clinicians to interpret individual subtests and make direct comparisons between subtests. Practitioners and researchers who elect to use the current normative data are encouraged to consider the similarities and differences between the present sample and their individual patients or research participants.
