Objective : The purpose of this study is to develop an independent living ability index for the use of mobility assistive technology devices.
Methods : The scale development process constitutes the content of an independent living ability index for the use of mobility assistive technology devices and develops the preliminary questions. In order to construct the preliminary questions, the questionnaire consists of the items of the evaluation scale through the literature research and findings from expert investigation. The contents validity is evaluated by examining the answers to the composed questions. Then, a questionnaire is given to the user about the developed evaluation scale to obtain reliability and validity. Finally, independent living ability index for the use of mobility assistive technology devices is completed.
Results : A total of 28 items was selected through both an exploratory factor analysis and a confirmative factor analysis. The mobility component had 12 items: two items in home mobility, four in work/school mobility, three in community mobility, and three items in outdoor mobility. The usability component had 16 items: five items in the usability of ambulation aids, five in the usability of manual wheeled mobility, and six items in the usability of powered wheeled mobility. They have statistical significance verified through the verification of content validity, reliability and validity
Conclusion : This study intended to develop an independent living ability index on people with disabilities using mobility ATDs and verify its reliability and validity. The significance of this study is as follows. Its methodological significance is attributed to the development of an objective index using statistical methods in the method development process. Its theoretical significance is attributed to the development of a method that systemizes the mobility component in consideration of various environments. Its practical significance is borne from its original intent to determine the extent of the independent living ability in various environments. The fact that clinicians and users participated in the item development to reflect the probability of daily living further increased its application possibilities.
