Abstract

Objectives: To determine whether caregiver opinion of fitness to drive and the level of assistance needed for functional activities are useful in determining the need for a Comprehensive Driving Evaluation. Methods: This study examined a sample (N = 179) of drivers with dementia. Caregivers completed a questionnaire that included caregiver opinion of driving fitness and the Functional Assessment Questionnaire (FAQ). A univariate simple logistic regression model was used to examine the relationship of road test failure with caregiver opinion of driving fitness and FAQ scores. From the significant predictive variables from the univariate test, multiple logictic regression models were used to examine possible combination of variables as predictors of road test failure. Results: The combination of caregiver opinion of driving fitness and the FAQ sub-item for memory were found to have modest ability in predicting failure on a standardized on-road driving assessment (AUC 0.727). Conclusions: Caregiver opinion of driving fitness and most individual higher order activities of daily living were found to be independent predictors of failure on a standardized road test. Clinical Implications: Caregiver opinion of driving fitness and ratings of functional activities may be useful for families and clinicians in considering whether an adult with dementia should be more carefully assessed for fitness to drive.
