Assessment of neurobehavioural disability: a review of existing measures and recommendations for a comprehensive assessment tool.
OBJECTIVE
Neurobehavioural disability (NBD) has a major impact on long-term psychosocial outcome: however, measures used to identify characteristics of NBD have not been fully evaluated. This review therefore discusses issues surrounding the concept and assessment of NBD following acquired brain injury (ABI) by examining the psychometric properties and other qualities of some of the most well known instruments used to assess NBD. It is the authors' intention to use this review to encourage researchers to develop new NBD measurement tools.


RESULTS
The review highlights a number of concerns with existing measures, including; the absence of a clear theoretical framework, a failure to distinguish impairment, disability and handicap when measuring characteristics of NBD and issues surrounding reliability and validity.


CONCLUSIONS
The authors propose, promote and encourage the development of further measures with improved reliability and validity to help ensure that the unique characteristics of NBD are captured more effectively.
