Sensitivity and specificity of the safe driving behavior measure and the driving habits questionnaire for older self-drivers.
Kweon-Young Kim, Chiang-Soon Song, Hye-Sun Lee
PMID 27821942WHAT IT FOUND
Driving questionnaires did not accurately identify collision history in 45 community-dwelling adults aged 65 to 74.
Neither the Safe Driving Behavior Measure nor the Driving Habits Questionnaire predicted reported collision history.
Key findings
01Neither the Safe Driving Behavior Measure nor the Driving Habits Questionnaire significantly predicted collision history.
02The AUC values were 0.501, 0.517, and 0.549 for the Safe Driving Behavior Measure domains and 0.593, 0.616, and 0.669 for the Driving Habits Questionnaire domains.
03Sensitivity was 0.538 for all Safe Driving Behavior Measure domains, and 0.577, 0.423, and 0.615 for the three Driving Habits Questionnaire domains.

What it does not show
The study included only 45 participants, so the accuracy estimates are limited. Only adults aged 65 to 74 were studied, so the results do not show how the questionnaires perform for middle-old or oldest-old drivers. The design was cross-sectional, and collision history was based on participant report. Participants with serious visual impairment, neurological deficits, severe orthopedic disease, missing limbs, major psychiatric diagnosis, or insufficient cognitive ability were excluded, so results may not apply to drivers with those conditions.
The easy way to misread this
Do not read the Driving Habits Questionnaire driving space AUC of 0.669 as evidence that it identifies drivers with collision history. The regression p value for driving space was 0.063, and the paper found no Safe Driving Behavior Measure or Driving Habits Questionnaire domain was a significant predictor of collision history.
