Objective:
To examine the measurement properties of the Community Integration Measure (CIM) in persons with traumatic brain injury (TBI).
Design:
Rasch analysis was used to retrospectively evaluate the CIM.
Setting:
Rehabilitation hospital.
Participants:
Persons (N=279) 1 to 15 years after a TBI.
Interventions:
None.
Main Outcome Measure:
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).
