The goal for this study was to develop an English translation of the Attention-Related Driving Errors Scale (ARDES-US) and to determine its potential relationship with driver history and other demographic variables.

Individual differences in performance on vigilance and cognitive tasks are well documented, but less is known about susceptibility to attention-related errors while driving. The ARDES has been developed and administered in both Spanish and Chinese but to our knowledge has never been administered or examined in an English-speaking population.

Two hundred ninety-six English-speaking individuals completed a series of self-report measures, including the ARDES-US, Attention-Related Cognitive Errors Scale, Mindful Attention Awareness Scale, and Cognitive Failures Questionnaire.

A confirmatory factor analysis using maximum-likelihood estimates with robust standard errors revealed results largely consistent with previous versions of the ARDES, namely, the ARDES-Spain and ARDES-Argentina. Additionally, a number of new results emerged. Specifically, women, drivers who received traffic tickets within the previous 2 years, and those with a lower level of education all had a greater propensity toward self-reported driver inattention as measured by the ARDES-US. Further analyses revealed that these findings were independent of age, years of driving experience, and driving frequency.

These results suggest that the ARDES-US is a valid and reliable measure of driver inattention with an English-speaking American sample.

Potential applications of the ARDES-US include identifying individuals who are at greater risk of attention-related errors while driving and suggesting individually tailored training and safety countermeasures.
