title: Rasch analysis of the community integration measure in persons with traumatic brain injury.
abstract: OBJECTIVE
  To examine the measurement properties of the Community Integration Measure (CIM) in persons with traumatic brain injury (TBI).
  
  
  METHODS
  Rasch analysis was used to retrospectively evaluate the CIM.
  
  
  METHODS
  Rehabilitation hospital.
  
  
  METHODS
  Persons (N=279) 1 to 15 years after a TBI.
  
  
  METHODS
  None.
  
  
  METHODS
  CIM RESULTS: The CIM met Rasch expectations of unidimensionality and reliability (person separation ratio=2.01, item separation ratio=4.52). However, item endorsibility was poorly targeted to the participants' level of community integration. A ceiling effect was found with this sample.
  
  
  CONCLUSIONS
  The CIM is a relatively reliable and unidimensional scale. Future iterations might benefit from the addition of items that are more difficult to endorse (ie, improved targeting).
