Approximately 40% of all drowning deaths involve a motor vehicle. Regardless of its significance as a cause of flood-related mortality, there is continued prevalence of driving through flooded waterways in Australia and worldwide. We aimed to understand the motivational determinates of driving through flooded waterways in low and high-risk scenarios by utilizing an augmented theory of planned behaviour (TPB) with behavioural willingness as the outcome variable as well as the influence of additional predictors; namely perceived risk and past behaviour. Participants (n=174; Mage=27.43, SD=10.76) answered standard TPB-based questions in regards to attitudes, subjective norm, and perceived behavioural control (PBC), as well as additional variables of perceived risk (i.e., perceived susceptibility and perceived severity) and past behaviour. Support was found for the augmented TPB as attitude, subjective norm, and PBC predicted behavioural willingness. Support was also found for perceived severity in the high-risk but not the low-risk scenario. No support was found for perceived susceptibility. Past behaviour emerged as a significant predictor of willingness in the low and high-risk scenario. The findings provide support for an augmented TPB in understanding individuals' willingness to drive through flooded waterways, suggesting that a multi-strategy approach may be critical in attempts to reduce the incidence of such risky driving behaviour.
在所有溺水死亡案例中，约40%与机动车有关。尽管作为与洪水相关的死亡原因，其重要性不容忽视，但在澳大利亚乃至全球，驾车通过被洪水淹没的水道这一现象仍普遍存在。我们旨在通过运用扩展的计划行为理论（TPB），以行为意愿作为结果变量，并考虑其他预测因素（即感知风险和过去的行为）的影响，来了解在低风险和高风险场景下驾车通过被洪水淹没的水道的动机决定因素。参与者（n = 174；年龄中位数 = 27.43，标准差 = 10.76）回答了基于TPB的关于态度、主观规范和感知行为控制（PBC）的标准问题，以及感知风险的其他变量（即感知易感性和感知严重性）和过去的行为。研究发现，扩展的TPB得到了支持，因为态度、主观规范和PBC预测了行为意愿。在高风险场景而非低风险场景中，感知严重性也得到了支持。未发现感知易感性的支持证据。过去的行为在低风险和高风险场景中均成为意愿的重要预测因素。这些发现为扩展的TPB在理解个人驾车通过被洪水淹没的水道的意愿方面提供了支持，表明多策略方法对于减少此类危险驾驶行为的发生率可能至关重要。
