Drink-driving is one of the key behavioral risk factors in road traffic safety. The main purposes of this study are the identification of the influence of drivers' subjective and objective factors on drink-driving behavior and the correlation between subjective and objective factors to design targeted measures for the prevention and control of drink-driving behavior.
To analysis the influence of the subjective and objective factors on the behavior of alcohol value simultaneously. A Bayesian structural equation model is conducted with the data collected via questionnaire issued on the Internet in China.
The results using the Bayesian structural equation model reveals that the subjective factors (e.g., drivers' behavior intention and perceived behavioral control) and objective factors (e.g., age, gender, and driving years of drivers) significantly affect drink-driving behaviors. Drivers' behavior intention is the strongest predictor, and perceived behavioral control also has a significant influence on drink-driving. Drivers who are male, older, lower driving years, driving a motorcycle or car and noncommercial vehicle have a higher probability in drink-driving. The results also suggest that there is a certain correlation between the driver's subjective and objective factors. For instance, male drivers have a more positive attitude toward drink-driving behaviors, drivers over thirty years old more cling to the region's alcohol culture and feel less guilty about drink-driving than youngsters, and truck or bus drivers perceived more disapproval of drink-driving behavior from their significant others.
A more nuanced understanding of the influence of drivers to drink-driving behavior can be found in these results. These results about the influence mechanism of subjective and objective factors on drink-driving behavior of this study have implications for governments and other interested bodies for better targeting and delivery of public education campaigns and interventions.
酒后驾车是道路交通安全中关键的行为风险因素之一。本研究的主要目的是识别驾驶员的主观和客观因素对酒后驾车行为的影响，以及主观因素和客观因素之间的相关性，以便为酒后驾车行为的预防和控制设计有针对性的措施。
通过在中国互联网上发布问卷收集数据，同时分析主观和客观因素对酒精值行为的影响。采用贝叶斯结构方程模型进行分析。
贝叶斯结构方程模型的结果表明，主观因素（如驾驶员的行为意图和感知行为控制）和客观因素（如驾驶员的年龄、性别和驾龄）显著影响酒后驾车行为。驾驶员的行为意图是最强的预测因素，感知行为控制对酒后驾车也有显著影响。男性、年龄较大、驾龄较短、驾驶摩托车或汽车以及非营运车辆的驾驶员酒后驾车的可能性更高。结果还表明，驾驶员的主观和客观因素之间存在一定的相关性。例如，男性驾驶员对酒后驾车行为的态度更为积极，三十岁以上的驾驶员比年轻人更依恋本地区的酒文化，对酒后驾车的内疚感也较少，卡车或公共汽车驾驶员的伴侣对酒后驾车行为的不认可程度更高。
这些结果可以更深入地了解驾驶员对酒后驾车行为的影响。本研究中关于主观和客观因素对酒后驾车行为影响机制的结果，对政府和其他有关方面具有重要意义，可以更好地针对酒后驾车行为开展公共教育活动和干预措施。
