Development of a new self-report questionniare[sic] : the Ambulatory Self-Confidence Questionnaire (ASCQ) Asano, Miho


Ambulation is one of the most important aspects of mobility as a whole. Difficulty with ambulation is a common problem among older adults in North America. Accordingly, maintaining or regaining their ambulation, at home and in the community, is a major goal and a great concern for older adults in rehabilitation programs. For researchers and clinicians in rehabilitation sciences, major goals and challenges include developing and using sufficient and effective measurement tools. Measurement tools that assess ambulation are an essential form of clinical and research information. While tests of walking speed and endurance are considered the gold standard for assessing ambulation, self-report approaches have recently become more accepted because they offer information not obtainable from the performance walk test. For instance determining individuals' confidence can be critical as studies have shown that confidence in performing a skill can be predictive of successful performance. Therefore, we created the Ambulatory Self-Confidence Questionnaire (ASCQ) because there was no existing measurement tool that captured this information. The ASCQ contains 22 items using item is scored from 0 (not at all confident) to 10 (extremely confident). The test-takers are asked to report how confident they are in their ability to walk in different situations. The objectives of this study included assessment of: 1) content validity of the ASCQ by a panel of experts; and 2) reliability and construct validity of the ASCQ among older adults. The results of the study suggest that: 1) the ASCQ evolved based on the experts' responses and was successfully created with valuable feedbacks; 2) the ASCQ demonstrated excellent internal-consistency and test-retest reliability; and 3) the support for construct validity was evident for a sample of older adults.
