OBJECTIVES: To evaluate the psychometric properties of the Spinal Cord
Injury-Functional Index/Assistive Technology (SCI-FI/AT) short forms (SFs) in the
domains of basic mobility, self-care, fine motor function, and ambulation based
on internal consistency; correlations between SFs and full item banks, and a
10-item computerized adaptive test (CAT) version; magnitude of ceiling and floor
effects; and measurement precision across a broad range of function in a sample
of adults with spinal cord injury (SCI). DESIGN:
Cross-sectional cohort study.
SETTING: Nine national Spinal Cord Injury Model Systems programs. PARTICIPANTS: A
sample of adults with traumatic SCI (N=460) stratified by level of injury
(paraplegia/tetraplegia), completeness of injury, and time since SCI.
INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES: SCI-FI/AT full item bank,
10-item CAT, and SFs (with separate Self-Care and Fine Motor Function SFs for
persons with tetraplegia and paraplegia). RESULTS: The SCI-FI/AT SFs demonstrated
very good internal consistency, group-level reliability, and excellent
correlations between SFs and scores based on the CAT version and the total item
bank. Ceiling and floor effects are acceptable (except for unacceptable ceiling
effects for persons with paraplegia on the Self-Care and Fine Motor Function
SFs). The test information functions are excellent across a broad range of
functioning typical of persons with paraplegia and tetraplegia. CONCLUSIONS:
Clinicians and researchers should consider using the SCI-FI/AT SFs to assess
functioning with the use of assistive technology when CAT applications are not available.
