Summary
This paper addresses the need for improved measurement tools to understand the underlying factors of driver distraction, a major contributor to vehicle crashes. While previous research developed the Susceptibility to Driver Distraction Questionnaire (SDDQ) to distinguish between voluntary (intentional) and involuntary (unintentional) distractions, the authors identified several limitations in the original 39-item tool. These included limited construct validity due to a small number of items, concerns regarding the applicability of social norms to certain distractions, poor test-retest reliability for some subscales, and the absence of a measure for habitual behaviors. To address these gaps, the authors developed an exploratory 400-item questionnaire designed to capture voluntary, involuntary, and habitual components of distraction more comprehensively. The methodology relies on the Theory of Planned Behaviour (TPB) to assess voluntary engagement, expanding on previous measures by using multiple questions and rating scales for attitudes, perceived behavioral control, and social norms. Attitudes are measured using semantic differential scales (e.g., safe vs. dangerous) and Likert scales for convenience and moral evaluation. Perceived behavioral control is differentiated into self-efficacy and controllability. Social norms are split into descriptive and injunctive types, with items restricted to distractions likely to have strong social norms. To account for driving context, the questionnaire incorporates two specific scenarios: a low-workload rural highway drive and a high-workload urban drive with heavy traffic. Habitual engagement is measured using the Self-Report Habit Index (SRHI), focusing on automaticity, lack of awareness, and identity rather than frequency. Involuntary distraction is assessed by probing the difficulty drivers face in ignoring salient, irrelevant stimuli and their tendency to engage in non-driving tasks longer than intended. The paper does not present empirical results from the administration of this new questionnaire, as it is designed for an upcoming online survey study. Instead, the findings consist of the theoretical framework and item construction for the exploratory tool. The authors detail how the new items address the specific shortcomings of the original SDDQ, such as providing context-specific scenarios to improve response accuracy and excluding distractions with weak social norms to enhance reliability. The inclusion of habitual behaviors allows for the investigation of automatic actions that were once intentional but now occur with minimal conscious control. The significance of this work lies in its potential to generate a more reliable and valid version of the SDDQ. By distinguishing between voluntary, involuntary, and habitual distractions, the improved questionnaire aims to better characterize individual differences in susceptibility to distraction. This refined measurement tool is intended to support the design of more effective countermeasures and mitigation strategies for driver distraction, ultimately contributing to road safety efforts. The next step involves administering the 400-item questionnaire and using factor analyses and reliability statistics to select the optimal items for the final instrument.
