Reliability and responsiveness of the Self-Efficacy in Assessing, Training and Spotting wheelchair skills (SEATS) outcome measure Rushton, Paula Wendy; Smith, Emma Maria; Miller, William C.; Kirby, R. Lee; Daoust, Geneviève

Abstract

Objectives. The aim of this study was to evaluate the internal consistency, test-retest reliability and responsiveness of the Self-Efficacy in Assessing, Training and Spotting manual wheelchair skills (SEATS-M) and Self-Efficacy in Assessing, Training and Spotting power wheelchair skills (SEATS-P). Methods: A 2-week test-retest design was used with a convenience sample of occupational and physical therapists who worked at a provincial rehabilitation center (inpatient and outpatient services). Sixteen participants completed the SEATS-M and 18 participants completed the SEATS-P. Results: For the SEATS-M assessment, training, spotting and documentation sections, Cronbach’s alpha coefficients ranged from 0.90-0.97, the 2-week intraclass correlation coefficients (ICC1,1) ranged from 0.81-0.95, the standard error of measurements (SEM) ranged from 5.06-8.70 and the smallest real differences (SRD) ranged from 6.24-8.18. For the SEATS-P assessment, training, spotting and documentation sections, Cronbach’s alpha coefficients ranged from 0.83-0.92, the ICCs ranged from 0.72-0.86, the SEMs ranged from 4.54-8.91 and the SRDs ranged from 5.90-8.27. Conclusions: Both the SEATS-M and the SEATS-P have good test-retest reliability and support for responsiveness. These tools can be used in evaluating clinician self-efficacy with assessing, training, spotting and documenting wheelchair skills included on the Wheelchair Skills Test.
