Development of a Knowledge Scale of Fall Risk Factors for Community-dwelling Older Adults

Purpose: The purpose of the study was to develop a knowledge scale of risk factors for fall among community-dwelling older adults. Further, the validity and reliability of the scale was developed. Methods: A preliminary scale was developed through content validity by five experts and targeted subjects using the CVI (Content Validity Index). Following the establishment of content validity, the scale was used with 359 community-dwelling older adults to further establish both validity and reliability of the scale. Specifically, construct validity using known-group comparison technique, and reliability using Cronbach's ${\alpha}$ were established. Results: After content validity testing, 44 preliminary items were selected. Construct validity was established by known group-comparison, in which scores between the fall and no fall groups were compared. The Cronbach's ${\alpha}$ of the final scale was .83. Conclusion: Reliability and validity of the scale were confirmed. This tool may be used for measuring knowledge of fall risk factor for the community-dwelling older adults.
