This study cross-culturally adapted the Wheelchair Skills Test-Questionnaire form to Brazilian Portuguese and examined its inter-rater and test-retest reliabilities. The Brazilian version showed excellent internal consistency and strong inter-rater reliability, indicating its usefulness in guiding practitioners in wheelchair skills training.
The Wheelchair Skills Test-Questionnaire form for Manual Wheelchairs Operated by Wheelchair Users (WSTQ-M-WCU 4.3) assesses wheelchair skills that may influence users' occupational performance in their daily activities. The purpose of this study was to cross-culturally adapt the WSTQ-M-WCU 4.3 to Brazilian Portuguese and to examine the inter-rater and test-retest reliabilities. This is a methodological study of cross-cultural adaptation and psychometric properties of reliability. The agreement achieved in the cross-cultural adaptation concerning idiomatic, cultural, conceptual and semantic aspects was 100%, 99.2%, 100% and 96.18%, respectively. We analyzed the test-retest and inter-rater reliabilities in a convenience sample of 46 manual wheelchair users using Cronbach's Alpha and Bland-Altman plots. The Brazilian version has excellent internal consistency (alpha > 0.9) and strong inter-rater reliability (p < .05). This instrument can guide practitioners in training wheelchair skills, thus contributing to the planning of interventions and for evidence-based practice in Assistive Technology.
