Objectives. Notwithstanding its economic importance, the construction industry is still facing challenges due to its high accident record. As a result, the goal of this study is to identify the key underlying causes of accidents in the Malaysian construction industry that construction stakeholders can focus on to reduce the menace of accidents in the industry. Methods. To achieve this goal, relevant literature was reviewed in order to identify the causes of accidents. The identified factors were used to develop the survey questionnaire for collecting primary data, and the collected data were analysed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). Results. The results of the EFA and CFA establish and confirm 11 clusters for the causes of accidents on construction sites: management problems; inadequate training; inadequate supervision; mental health problems; bad attitudes; inadequate funding; inadequate experience; material and equipment handling; poor safety practices; inadequate orientation; and work environment. Conclusion. The study concludes that addressing all 11 factors will drastically reduce the incessant accident occurrences in the construction industry. The result of this study will help construction stakeholders know where to direct their energy in an effort to reduce construction accidents.
