OBJECTIVE: Replicate and extend studies of the construct validity of the Functional Independence Measure (FIM) for persons with traumatic brain injury (TBI). DESIGN: A cross-sectional study of admissions to acute rehabilitation evaluated 6 months to 5 years after discharge. SETTING: An inpatient brain injury rehabilitation unit in a large, academic medical center. SUBJECTS: Ninety-five patients with primary diagnosis of TBI stratified by time postdischarge. MAIN OUTCOME MEASURES: Prediction of (1) average daily minutes of assistance and (2) supervision required in comparison to the Sickness Impact Profile (SIP) and SF-36. RESULTS: The FIM was highly predictive of minutes of assistance (83% accuracy), supervision (82% accuracy), and the need for either type of assistance (78% accuracy). Prediction was only minimally improved by measures of neurobehavioral impairment. The accuracy of the FIM was superior to the SIP and SF-36. CONCLUSIONS: Results provided substantial support for the validity of the FIM as a measure of functional independence for persons with TBI. The importance of supervision as a type of assistance required after TBI was evident, with the FIM highly predictive of this need, as well.
