OBJECTIVE: To evaluate the psychometric properties of the Spinal Cord
Injury-Functional Index (SCI-FI) short forms (basic mobility, self-care, fine
motor, ambulation, manual wheelchair, and power wheelchair) based on internal
consistency; correlations between short forms banks, full item bank forms, and a
10-item computer adaptive test version; magnitude of ceiling and floor effects;
and test information functions. DESIGN: Cross-sectional cohort study. SETTING:
Six rehabilitation hospitals in the United States. PARTICIPANTS: Individuals with
traumatic spinal cord injury (N=855) recruited from 6 national Spinal Cord Injury
Model Systems facilities. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURES:
SCI-FI full item bank, 10-item computer adaptive test, and parallel short form
scores. RESULTS: The SCI-FI short forms (with separate versions for individuals
with paraplegia and tetraplegia) demonstrate very good internal consistency,
group-level reliability, excellent correlations between short forms and scores
based on the total item bank, and minimal ceiling and floor effects (except
ceiling effects for persons with paraplegia on self-care, fine motor, and power
wheelchair ability and floor effects for persons with tetraplegia on self-care,
fine motor, and manual wheelchair ability). The test information functions are
acceptable across the range of scores where most persons in the sample performed.
CONCLUSIONS: Clinicians and researchers should consider the SCI-FI short forms
when computer adaptive testing is not feasible.
