OBJECTIVES: To develop a comprehensive set of patient-reported items to assess
multiple aspects of physical functioning relevant to the lives of people with
spinal cord injury (SCI), and to evaluate the underlying structure of physical
functioning. DESIGN: Cross-sectional. SETTING: Inpatient and community.
PARTICIPANTS: Item pools of physical functioning were developed, refined, and
field tested in a large sample of individuals (N=855) with traumatic SCI
stratified by diagnosis, severity, and time since injury.
INTERVENTIONS: None.
MAIN OUTCOME MEASURE: Spinal Cord Injury-Functional Index (SCI-FI) measurement
system. RESULTS: Confirmatory factor analysis (CFA) indicated that a 5-factor
model, including basic mobility, ambulation, wheelchair mobility, self-care, and
fine motor function, had the best model fit and was most closely aligned
conceptually with feedback received from individuals with SCI and SCI clinicians.
When just the items making up basic mobility were tested in CFA, the fit
statistics indicated strong support for a unidimensional model. Similar results
were demonstrated for each of the other 4 factors, indicating unidimensional
models. CONCLUSIONS: Though unidimensional or 2-factor (mobility and upper
extremity) models of physical functioning make up outcomes measures in the
general population, the underlying structure of physical function in SCI is more
complex. A 5-factor solution allows for comprehensive assessment of key domain
areas of physical functioning. These results informed the structure and
development of the SCI-FI measurement system of physical functioning.
