Abstract
Purpose: To investigate the score distribution, reliability, and validity of the objective Wheelchair Skills Test (WST) for scooter users.
Method: A study using a test–retest design was conducted with 20 people who had mobility limitations that prevented them from ambulating more than one city block without a mobility aid, and who had owned a scooter for ≥3 months. Objective scooter skills, confidence, and physical accessibility were measured at both time points, while anxiety, depression, visual attention and task switching, functional independence, and visual acuity were measured only at baseline.
Results: The mean total WST scores at Time 1 and Time 2 were 86.3% and 87.5%. The WST ICC was 0.889. The WST had a SEM of 2.50 and a Cronbach’s alpha of 0.74. The total WST scores were significantly correlated with total subjective WST-Q scores (r = 0.547, p = 0.013), scooter confidence (r = 0.466, p = 0.038), and were affected by gender (p = 0.005).
Conclusion: The WST for scooters has good test–retest reliability and generally varies as anticipated with other measures. Although further study is needed, the WST for scooters appears to have promise for use in research and clinical practice.
It is important to understand the measurement properties of the tools we use in rehabilitation so the results can be interpreted correctly.
As scooter use increases, better measurement of skills is required.
