OBJECTIVE Driving simulation provides a convenient and safe method for assessing driving behaviors. Many authors, however, agree that validation is a key component of any study that utilizes simulators to assess driving performance. The purpose of this study was to test driver response validity by discerning whether behavioral responses of drivers, as(More)
With 2003 Fatality Analysis Reporting System data, we examined relationships among predictors of motor vehicle injury/fatality outcomes for younger (35-54 years) and older (65 years and older) drivers. Using the Precede-Proceed Model of Health Promotion as an organizing framework, we classified variables into person, vehicle and environment domains and(More)
PURPOSE To determine the correlations of the Useful Field of View (UFOV), compared to other clinical tests of Parkinson's disease (PD); vision; and cognition with measures of on-road driving assessments and to quantify the UFOV's ability to indicate passing/failing an on-road test in people with PD. METHODS Nineteen randomly selected people with(More)
OBJECTIVES To determine the relationship between clinical variables (demographics, cognitive testing, comorbidities, and medications) and failing a standardized road test in older adults. METHODS Analysis of on-the road studies performed in optimal weather conditions, between January 1, 2005, and May 1, 2007. The standardized testing was held at the(More)
Certain driving errors are predictive of crashes, but whether the type of errors evaluated during on-road assessment is similar to traffic violations that are associated with crashes is unknown. Using the crash data of 5,345 older drivers and expert reviewers, we constructed a violation-to-error classification based on rater agreement. We examined the(More)
The topic of motor vehicle crashes among the elderly is dynamic and multi-faceted requiring a comprehensive and synergistic approach to intervention planning. This approach must be based on the values of a given population as well as health statistics and asserted through community, organizational and policy strategies. An integrated summary of the(More)
OBJECTIVE Systematic literature reviews contribute to evidence-based occupational therapy, yet no data capture tool currently exists to validly and reliably appraise the characteristics and quality of primary studies. METHOD We determined the psychometrics of Systematic Process for Investigating and Describing Evidence-Based Research (SPIDER) and piloted(More)
OBJECTIVES We examined the validity of our on-road driving assessment to quantify its outcomes. METHOD Older drivers (N = 127) completed a driving assessment on a standardized road course. Measurements included demographics, driving errors, and driving test outcomes; a categorical global rating score (pass-fail); and the sum of maneuvers (SMS) score(More)
OBJECTIVE The object of this research was to identify interactions among person, vehicle, and environment factors associated with crashes and injuries among older drivers. METHOD We quantified risk factors and interactions for 5,744 drivers. RESULTS Women had a high crash risk during mornings (8:00 a.m.-1:00 p.m.; odds ratio [OR] = 1.73, confidence(More)
