Reliability and Predictive Validity of the American Medical Association's Older Driver Screening Protocol

Funded by: National Highway Traffic Safety Administration
Principal Investigator: Dennis McCarthy

The physicians are often forefront in the decision to stop driving but until recently, they have not had guidelines for screening those older persons who might be at risk of crashes. The American Medical Association (AMA) recently published The Physician's Guide to Assessing and Counseling Older Drivers (2003). This guide offers a screening tool, the Assessment of Driving Related Skills (ADReS) that can be administered within a 10 to 15 minute timeframe. Results of the ADReS assist the physician in making recommendations to, and provide referrals for, their patients. However, the reliability and validity of the ADReS has yet to be established. This study will determine: 1) physicians' current practices with regard to their patients' safe driving abilities; 2) physicians' knowledge and use of both the Guide and the ADReS; 3) the interrater reliability of ADReS administration, and; 4) the reliability and validity of the ADReS screening tool. Working closely with the AMA, NODRTC has assembled an expert team of physicians, researchers, and practitioners to help develop questions to ask physicians about their current knowledge and practices regarding older drivers. Additionally, research participants will undergo an on-road, behind-the-wheel driving evaluation following ADReS administration. The results will be analyzed to determine the sensitivity of this screening tool in identifying those who may need further evaluation of driving performance.
