There are three main research hypotheses for this study. Firstly, it is hypothesised that early intervention, in the form of the information and planning group, will not be associated with either increases or decreases in driving assessment failure or driving cessation. Secondly, it is hypothesised that early intervention will be associated with patterns of reduced depression and less persistent negative mood states. Thirdly, it is hypothesised that early intervention will be associated with patterns of sustained levels of important quality of life indicators such as community participation and social relationships.
