This study validates the Vietnamese versions of the Driving Anger Scale and Driving Anger Expression Inventory, two prominent instruments for determining driving anger proneness and expression. Using these scales, the authors investigate the relationships between driving anger and motorcyclists' on-road risks in Vietnam.
Factor analyses are conducted to explore the dimensional constructs of the two scales with a dataset of 960 Vietnamese motorcyclists. The t-tests were applied to assess the differences in driving anger levels between motorcyclists' subgroups. Negative binomial regression is used to predict the probability of motorcyclists' traffic incidents based on driving anger factors and individual differences.
The Vietnamese Driving Anger Scale has three factors, including Hostile gestures (α=.78), Unpleasant conditions (α=.80), and Traffic violations (α=.74). Hostile gestures elicit the most driving anger among Vietnamese motorcyclists. Besides, females report higher propensities for driving anger than males over three anger-provoking factors. The Driving Anger Expression Inventory has a two-factor structure, including Aggressive expressions (α=.83) and Adaptive expressions (α=.74). Vietnamese motorcyclists are more prone to have adaptive expressions than aggressive expressions when angry on-road. The regression results reveal the significant effects of gender and two factors of the Driving Anger Expression Inventory on the probability of traffic incidences. Females have considerably fewer traffic accidents and offenses than males. Besides, the number of minor crashes and violations grows by 1.54 and 1.93 times with each unit rise of the Aggressive expressions factor. Increasing adaptive expression level is associated with a decrease in the numbers of major crashes and offenses (40% and 19% less, respectively).
This study provides insights into driving anger in Vietnam, a motorcycle-dominant country. The findings corroborate the Vietnamese versions of the Driving Anger Scale and Driving Anger Expression Inventory, which contributes to understanding the formation and expression of driving anger and its roles in predicting driving outcomes. Furthermore, the higher on-road risks of males and motorcyclists with more aggressive expressions are highlighted. Generally, enhancing the risk perception about driving anger and promoting the advantages of on-road adaptive expressions may significantly reduce traffic issues in Vietnam.
本研究验证了越南版驾驶愤怒量表和驾驶愤怒表达量表，这两个工具常用于确定驾驶愤怒倾向和表达。使用这些量表，作者研究了驾驶愤怒与越南摩托车手道路风险之间的关系。
使用 960 名越南摩托车手的数据进行因子分析，以探讨两个量表的维度结构。采用 t 检验评估摩托车手亚组之间驾驶愤怒水平的差异。采用负二项回归预测驾驶愤怒因素和个体差异对摩托车手交通事故的概率。
越南驾驶愤怒量表有三个因素，包括敌对手势（α=.78）、不愉快条件（α=.80）和交通违规（α=.74）。敌对手势引起了越南摩托车手最大的驾驶愤怒。此外，女性在三个引发愤怒的因素上比男性表现出更高的驾驶愤怒倾向。驾驶愤怒表达量表有两个因素结构，包括攻击性表达（α=.83）和适应性表达（α=.74）。当越南摩托车手在路上生气时，他们更倾向于有适应性表达而不是攻击性表达。回归结果显示，性别和驾驶愤怒表达量表的两个因素对交通事故概率有显著影响。女性发生交通事故和违规的次数明显少于男性。此外，攻击性表达因子每增加一个单位，轻微碰撞和违规的次数就会增加 1.54 倍和 1.93 倍。增加适应性表达水平与重大事故和违规次数减少有关（分别减少 40%和 19%）。
本研究提供了对越南驾驶愤怒的深入了解，越南是一个以摩托车为主导的国家。研究结果证实了越南版驾驶愤怒量表和驾驶愤怒表达量表的有效性，有助于理解驾驶愤怒的形成和表达及其在预测驾驶结果中的作用。此外，还强调了男性和更具攻击性表达的摩托车手更高的道路风险。总的来说，提高对驾驶愤怒的风险认知，并促进道路适应性表达的优势，可能会显著减少越南的交通问题。
