Adelaide Driving Self-Efficacy Scale (ADSES)

The Adelaide Driving Self-Efficacy Scale (ADSES) is a self-report questionnaire designed to measure an individual’s perceived abilities as they relate to 12 driving-related activities/conditions and is loosely based on self-efficacy theoretical models, such as that postulated by Bandura, that argue that a belief in one’s own ability to organize and execute the necessary courses of action are necessary to achieve goal attainment (George, Clark, & Crotty, 2007). The ADSES is composed of 12 driving scenarios, such as driving in heavy traffic or driving at night, in which the subject is asked to rate how confident he or she feels when performing or if asked to perform those scenarios along a scale from 1 to 10 where 1 is not confident and 10 is completely confident. The measure has a maximum score of 120 with higher scores signifying that the subject has more self-perceived driving ability. The ADSES can be completed in less than 10 minutes.
