Examining the repeatable battery for the assessment of neuropsychological status: factor analytic studies in an elderly sample.
OBJECTIVE
The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS), a recently developed cognitive assessment instrument, has been shown to be useful with a variety of neuropsychiatric conditions, but its factor structure has not been examined.


METHODS
Using 824 community-dwelling elders, the RBANS was examined with confirmatory and exploratory factor analyses.


RESULTS
The existing structure of the RBANS was not supported; however, a two-factor solution was.


CONCLUSIONS
Clinicians and researchers using the RBANS should be cautious when interpreting this measure with its existing structure.
