["This study aimed to investigate: (i) whether attitudes and beliefs about driving predict older adults' driving self-regulation, and how much variance in self-regulation can be explained by these factors; and (ii) if driving confidence is controlled, whether attitudes and beliefs remain significant independent predictors of driving self-regulation.", 'The present study examined the psychosocial factors that underlie driving self-regulation in 277 older adults within Australia. Participants completed standardised questionnaires about their driving, attitudes, belief and use of driving self-regulation.', 'Driving confidence, affective and instrumental attitude, and perceived behavioural control were all significant predictors of driving self-regulation. The combination of these factors accounted for 56% of the variance in driving self-regulation.'] Do psychosocial factors significantly predict driving self-regulation in Australian older adults?
