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: Post-acute rehabilitation hospital.
PARTICIPANTS: 279 persons 1-15 years after a TBI.
INTERVENTIONS:: None.
MAIN OUTCOME MEASURES:: Community Integration Measure.
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 particianpts' 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 (i.e., improved targeting).
