Abstract

Appropriate self-regulation of driving - that is, adjusting one s driving patterns by driving less or avoiding specific situations considered challenging - shows promise as a strategy for extending safe driving. However, results on the extent of self-regulatory practices among older drivers vary considerably across studies. Method The purpose of this study was to develop and test a questionnaire to measure self-regulation at multiple levels of driver performance and decision making, using a sample of older drivers comprised of individuals with clinically-determined functional impairments, as well as older adults recruited from the general population. Results Results suggest that the questionnaire is a user-friendly instrument for gathering information from older adults about their self-regulatory practices which has good construct validity. Feedback on the questionnaire was positive. Construct validity of the questionnaire was assessed by comparing the recruitment populations along various dimensions on which they might be expected to differ (e.g., self-rated health and functioning, abilities for safe driving, and feelings of driving comfort/safety) and looking for correlations between variables that one would reasonably expect to be correlated. Conclusions Overall, participants rated their general health and functioning, and abilities for safe driving quite highly. However, participants from the clinic population rated themselves lower than participants from the general population on several abilities including seeing clearly during the day and night, remembering things, and processing information. While participants reported high levels of driving comfort and safety for most driving situations, the clinic population reported lower levels of comfort and safety for every driving circumstance except driving alone.
