Construct validity of the Repeatable Battery of Neuropsychological Status (RBANS) with acquired brain injury patients.

The construct validity of the Repeatable Battery for the Assessment of Neuropsychological Status (RBANS) indices and subtests in comparison to established neuropsychological measures has yet to be investigated in post-acute adults with a moderate to severe acquired brain injury. A sample of 37 patients from an inpatient brain injury rehabilitation program were administered the RBANS followed by a neuropsychological test battery approximately two weeks later. Significant relationships were observed between most of the RBANS subtests and indices and neuropsychological tests putatively assessing similar cognitive domains. These results provide preliminary support for the construct validity of the RBANS indices and subtests when used with moderate to severe acquired brain injury patients.
