An important justification for this study is to examine the effects of a new concept of early intervention. Previous forms of intervention with existing senior drivers prior to assessment have involved activities such as public education and mature driver workshops. These have been evaluated in terms of the growth of knowledge and driving safety. In contrast, the new concept of early intervention involves activities such as group change strategies, positive psychology approaches and topic based discussion designed to mitigate the health and quality of life effects of regulation and cessation. In researching this new concept of early intervention, this project is intended to open up a new field for research. It will provide evidence of what effects can follow from early intervention and will indicate topics to be explored in subsequent research. In addition it will establish a model for the longitudinal research of senior drivers.
