ABSTRACT

Objective : This study aims to identify the self-reported driving abilities of elderly drivers and their correlations tothe demographic factors that influence them, and to verify the adequacy of the hypothetical model, constructedbased on vision, auditory, cognition, motor, and psychological factors, in order to present a path model on theself-reported driving abilities of elderly drivers. Methods : The participants in this study were 122 elderly drivers aged 65 years or older residing in the community. This study evaluated the following factors of the participants: Vision and hearing, motor ability, cognitive ability,depression, self-reported driving abilities. Results : The results of this study are as follows. In the case of men, the self-reported driving ability score washigher than for women, and those driving 6-7 days per week had higher scores than those driving 3 days or less. The period of holding a driver's license and driving experience positively correlated with self-reported drivingabilities. The final model of factors influencing the self-reported driving abilities of elderly drivers had a p value(.911) exceeding .05; TLI (1.202), NFI (.949), and CFI (1.000) of over .90; and RMSEA (.000) of lower than 0.1,indicating that the hypothesis model fit the data well. First, the directly influential factors on the self-reporteddriving abilities of elderly drivers were depression, decreased hearing, and grip strength. Second, age was foundto have a direct influence on depression and grip strength; moreover, depression and grip strength as a mediatorindirectly influenced their self-reported driving abilities. Third, depression was found to have a direct influence ontheir delayed cognitive processing and grip strength. Conclusion : The significance of this study is in the identification of direct and indirect factors influencing theself-reported driving abilities of elderly drivers in regional communities, and in the verification of multi–dimensional effects of diverse factors influencing such abilities.
