Changes in older drivers’ self-awareness of driving ability over one year

Older drivers’ self-awareness of driving ability can prompt self-regulatory behaviors and modifications of their everyday driving performance. To date, studies have yet to examine how older drivers’ self-awareness of changes in driving ability over time or identify the characteristics of those who can accurately monitor such changes. 64 older drivers (Age: Mean = 80.0 years, SD = 5.4; male: 70 %) were recruited and categorized into four groups based on the correspondence of changes in their perceived and actual driving ability over one year: 40 % of the participants were accurate in their stable or better driving ability over time, 30 % did not detect their driving performance had worsened and over-estimated their driving ability, and the remainder either accurately detected their performance had worsened or under-estimated their driving performance. No demographic or clinical factors were associated with older drivers’ self-awareness of changes in driving ability over time, except the mental processing and executive functioning measured using the Trail Making Tests Part B, showed a marginal effect. Implications for clinical importance are discussed.
