This project examined four issues with respect to driving cessation. The issues were: 1) group differences as a function of driving status, 2) prediction of driving cessation, 3) the utility of using comprehensive measure of subjective well-being to assess the impact of driving cessation, and 4) the identification of variables that moderate the relationship between driving cessation and subjective well-being. Non-institutionalized persons age 55 years and older were recruited from community, volunteer, and non-profit organizations in Winnipeg, Manitoba and Thunder Bay, Ontario. Two-hundred and twenty-three participants ranging in age from 55 to 91 years completed the study. Of these, 193 (86.9%) were drivers and 29 (13.1%) participants were non-drivers. Drivers were younger, in better health, and had higher income and education. Drivers also scored higher on extraversion and lower on neuroticism. Drivers also reported higher life control and life purpose and a more internal locus of control. Among current drivers, logistic regression analysis revealed that psychological variables make a significant unique contribution to predicting driving cessation. Higher life purpose and a more internal locus of control decrease the risk of driving cessation. With respect to the third issue, a comprehensive measure of subjective well-being, the MUNSH, provided a more sensitive assessment of the impact of a set of variables associated with driving cessation on subjective well-being. With respect to moderating factors, income health, and psychological variables moderated the impact of cessation on subjective well-being. The findings of this study indicate that psychological variables are important in driving issues and that it is valuable to study positive aspects of driving cessation in future research.
