Modeling of Factors Affecting the Prevention of Accidents in Construction Sites Using Structural Equation

Due to the increase in population rates and the extensive growth of the construction industry in developing countries, the trend of occupational accidents in this sector has been increasing in recent years. In order to minimize such accidents, research must be conducted on the cause of occurrence and prevention methods of these accidents. Therefore, the current research was carried out with the aim of identifying and determining the impact of effective factors on the prevention of accidents at construction sites, using a descriptive-analytical method in terms of nature and practical in terms of purpose. The statistical population included supervisors and supervising engineers of construction sites with more than 10 years of experience working on construction sites in Kermanshah city. The primary information was collected through document-library review and based on the expert opinions, the effective factors in preventing accidents at construction sites were classified under three categories: managerial, individual and environmental. The primary research tool was a questionnaire, and SPSS and Smart PLS software were used to analyze the data. Model analysis was conducted by the structural equation modeling method with partial least squares approach. The results showed that the conceptual model of the research had a favorable fit. All relationships between sub-factors and factors were significant, and the managerial factor with a path coefficient of 0.724 had the greatest impact and the environmental factor with a path coefficient of 0.309 had the least impact on the prevention of accidents at construction sites.
