One-week retest methodological study.Objectives:To assess the
reliability and validity of the wheelchair outcome measure (WhOM) in a sample of
individuals with spinal cord injury (SCI).Setting:Vancouver, British Columbia,
Canada.Methods:The WhOM measures the impact of wheelchair interventions on a
user's self-selected participation outcomes. The WhOM was administered to 50
participants on two occasions by the same rater, 1 week apart, to assess
test-retest reliability. To determine inter-rater reliability, the WhOM was
administered a third time approximately 72 h later by a different rater. Validity
was evaluated by correlating scores from the WhOM with scores from the Assessment
of Life Habits (LIFE-H).Results:The test-retest intraclass correlation
coefficients (ICC(2, 2)) for the WhOM satisfaction (Sat) and WhOM importance
(Impt) x Sat scores were 0.83 (95% confidence interval (CI), 0.72-0.90) and 0.88
(95% CI, 0.79-0.93), respectively. The inter-rater ICC for the WhOM Sat and WhOM
Impt x Sat scores were 0.91 (95% CI, 0.85-0.95) and 0.90 (95% CI, 0.83-0.94),
respectively. As hypothesized, most scores on the WhOM were fair to moderate
(r=0.3-0.5) and positively correlated with scores on the LIFE-H.Conclusion:The
WhOM is a new outcome measure that demonstrates good reliability and validity
among individuals with SCI. It is designed to assist wheelchair users identify
and evaluate the impact of wheelchair interventions on participation level
outcomes. The WhOM may be applicable for clinical- or research-oriented purposes.
