Introduction: Construction sites exhibit unique hazardous characteristics. Hence, investigating the causes of fatal and nonfatal accidents is extremely important to promote safety on construction sites. Literature shows a risk perception (RP) scale for construction workers; to expand the existing research, this study aims to identify risky scenarios for assessing the RP of Thai construction workers, with the goal of reducing workplace incidents. Method: The scale development process consists of four phases. Item development was also performed, followed by factor analysis. Reliability and validity assessments were finalized in the process. A survey of 500 construction workers in Thailand was conducted to investigate risky scenarios. Through the process, a total of 17 items remained in the final RP scale, and the reliability and validity of these items were confirmed. Results: The RP scale was affirmed to have four dimensions (probability, severity, worry, and unsafe). These dimensions of workers’ RP were negatively correlated with the workers’ risk-taking behaviors. This study further showed that participants with a high level of affective RP were more likely to have a high level of cognitive RP. Hence, those with a high level of RP tended to be involved in fewer risk-taking behaviors. Practical Applications: The final version of the scale was reliable and valid in determining the RP and risk-taking behaviors of construction workers in Thailand.

简介：建筑工地表现出独特的危险特性。因此，调查致命和非致命事故的原因对于促进建筑工地的安全极为重要。文献显示了建筑工人的风险感知 (RP) 量表；为了扩展现有研究，本研究旨在确定评估泰国建筑工人 RP 的风险情景，目的是减少工作场所事故。方法：规模发展过程包括四个阶段。还进行了项目开发，然后进行了因素分析。在此过程中最终确定了可靠性和有效性评估。对泰国 500 名建筑工人进行了一项调查，以调查风险情景。通过这个过程，最终的RP量表共剩下17个项目，并验证了这些项目的信度和效度。结果：RP 量表被确认有四个维度（概率、严重性、担心和不安全）。工人 RP 的这些维度与工人的冒险行为呈负相关。这项研究进一步表明，具有高水平情感 RP 的参与者更有可能具有高水平的认知 RP。因此，那些具有高水平 RP 的人往往参与较少的冒险行为。实际应用：该量表的最终版本在确定泰国建筑工人的 RP 和冒险行为方面是可靠和有效的。
