Objective : This study was conducted for the purpose of developing and verifying an assessment tool that can more objectively assessment driving skills for safe and independent activities and participation of powered wheelchair users.
Methods : In order to extract the final assessment items, a literature review was conducted on the assessment tools for powered and manual wheelchair mobility skills abroad, and also an expert opinion survey, analysis of the mobility environment of powered wheelchair users, and content validity of experts were conducted. To verify the evaluation tool, 30 persons with physical disabilities and brain lesions were subject to test-retest and concurrent validity.
Results : As a result of verifying reliability and validity of 30 powered wheelchairs for the final developed assessment tool, Cronbach's α was high from .909 to .928 in each assessment item, and the correlation coefficient was .936 as a result of test-retest reliability verification(p<.01). It was analyzed that the reliability was excellent as it appeared to be high. As a result of WST-P-Q 5.0 concurrent validity analysis, the correlation coefficient for all factors was .750, which was analyzed to have high validity (p<.01).
Conclusion : The driving skill ability assessment tool is the first assessment tool that can assess the ability to use a powered wheelchair before using it and provide systematically comparable data on training performance.
