Abstract:
Rasch analysis was applied to 1-year follow-up data from the national Traumatic Brain Injury (TBI) Model Systems database to identify the dimensions of functional and community outcomes and the items needed to measure these outcomes in TBI research. Items selected for analysis included all items indicative of global outcomes, disability, activity, or participation. Results indicated that functional, psychosocial, and community outcomes after TBI can be measured by a powerful singular general dimension, which might be called "general functioning in the community". This dimension fit over 90 percent of the cases. Item reliability was high, as was person reliability.
