The applicability of the precaution adoption process model in understanding older adults' self-regulatory driving behaviours

Age-related declines can compromise older adults' abilities to drive safely. Researchers have promoted self-regulation as a positive approach that can balance the needs for mobility and safety. The lack of a theoretically-informed model of driving self-regulation inhibits our ability to understand and describe such complex process. This thesis contributes to the theoretical understanding of older drivers' self-regulation by examining the applicability of the Precaution Adoption Process Model in categorising older adults into different stages of behaviour change while capturing a wide range of interpersonal, intrapersonal, and environmental factors that influence self-regulatory driving behaviour
