title: Neurobehavioral functions evaluated in naturalistic contexts: Rasch analysis of the A-ONE Neurobehavioral Impact Scale.
abstract: OBJECTIVE
  The fact that different neurobehavioral impairments affect daily life task performance of clients with different neurological diagnoses currently restricts between-group comparisons in rehabilitation. The purpose of this study was to determine whether a single neurobehavioral impact scale could be constructed for use with different diagnostic groups.
  
  
  RESULTS
  Rasch analysis of 422 clients (diagnosed with CVA and dementia) demonstrated that 29 of 55 items from the A-ONE Neurobehavioral Scale could be used to construct a short-form, Common Scale.
  
  
  CONCLUSIONS
  While the use of different and longer diagnostic-specific scales versions may be more useful clinically, the short-form, Common Scale has the potential to be used in research focusing on comparison of groups. Further research will be needed to validate the common, short version.
