title: Rating scale analysis of the Neurobehavioral Cognitive Status Examination.
abstract: OBJECTIVE
  Evaluate the measurement properties of the Neurobehavioral Cognitive Status Examination (NCSE) using rating scale analysis.
  
  
  METHODS
  Calibration of item responses collected as part of a study examining characteristics of case-management programs and treatment outcomes.
  
  
  METHODS
  Three outpatient rehabilitation facilities.
  
  
  METHODS
  Convenience sample of 186 community-dwelling adults with TBI.
  
  
  RESULTS
  Several rating scale analyses were performed to construct a unidimensional measure. Deletion of easy and misfitting items created a better targeted test (generated more spread among individuals) without increased error.
  
  
  CONCLUSIONS
  If used with a community-based sample, three strata can be differentiated despite a skewed distribution. Recommended applications are with samples with considerably more cognitive impairment.
