Item Development to Predict the Driving Risk of Older Drivers using the Delphi Method

Abstract

Increasingly, the elderly population is preferring a more-active lifestyle. These seniors can achieve more active social participation through driving. However, elderly drivers are required to undergo safety screening because of the high risk of accidents. Therefore, this study aimed to develop evaluation items for screening the driving risk of elderly drivers using a Delphi survey. The researchers collected the items included in the existing self-reported test of the elderly drivers and the 52 selected pre-items were those contained in at least two of the existing tests. Delphi panels were composed of professors, occupational therapists, social workers, road traffic workers and an elderly driver. In the first and second Delphi surveys, four items were integrated and 48 items were derived. The final 44 items were derived from the results of the third Delphi survey. The final 44 items contained information related to driving by elderly individuals and so can be used to formulate an appropriate test for elderly drivers. In various countries, self-evaluation for elderly drivers is provided as an IT-based service. It is expected that the items developed in this study will be used to develop Korean IT-based services for elderly drivers in Korea.
