摘要

Attention regulation ability is essential to guarantee safety while driving. However, due to the lack of valid measurement instruments, studies of attention regulation, attention error, and driving styles in China are limited. Additionally, the relationship between drivers’ attention regulation and crash involvement remains unexplored. This study adapted the Driver Attention Regulation Scale (DARS) to Chinese drivers and examined its reliability and validity. Seven hundred drivers aged 19–60 years participated in this study and completed the DARS, the Multidimensional Driving Style Inventory Scale (MDSI), the Attention-Related Driving Errors Scale (ARDES) and the Attention-Related Cognitive Errors Scale (ARCES). Exploratory factor analysis (n = 206) and confirmatory factor analysis (n = 471) were used to examine the factorial structure of the DARS. The revised DARS consists of 15 items that are divided into 3 factors: attention presence, attention flexibility, and attention capacity. The results of CFA indicated that the model fit of the DARS was acceptable. The reliability was 0.85 for attention presence, 0.91 for attention flexibility, and 0.84 for attention capacity. The DARS factors were weakly or moderately correlated with attention errors as measured using both the ARDES and ARCES, and MDSI factors (e.g., dissociative style), providing preliminary evidence for its convergent and external validity. Cluster analysis revealed that compared with drivers in Cluster 1, drivers in Cluster 2 had more penalty points and traffic crashes and scored lower on the careful driving style, attention presence and capacity factors of the DARS but higher on anxious, angry, and dissociative driving styles. These findings provide preliminary, exploratory evidence that DARS scores may differentiate driver subgroups with distinct risk profiles, though further validation is required. The DARS demonstrates acceptable reliability and validity and may serve as a promising tool for assessing the attention regulation ability of drivers in China.
