The current study evaluated part of the Multifactorial Model of Driving Safety to elucidate the relative importance of cognitive function and a limited range of standard measures of visual function in relation to the capacity to drive safely.
Community dwelling drivers aged 65 to 96 were assessed using a battery of measures of cognitive and visual function.
Factor analysis of these predictor variables yielded factors including executive/speed, vision (measured by visual acuity and contrast sensitivity), spatial, visual closure and working memory.
Cognitive and vision factors explained 83 to 95% of age related variance in the capacity to drive safely.
