Background and aims: Safety culture of an organization is an essential strategy to reduce occupational accidents, and many industries around the world have shown their willingness to consider the concept as an approach to reduce daily incidents and potential disasters. The aim of this study is to design a valid tool for measuring safety culture, which is based on a model of the International Atomic Energy Agency (IAEA).
Methods: This is a descriptive-analytic study performed on 409 employees of an oil and gas exploration company in Ahvaz in 1392. After the initial questionnaire was prepared by the IAEAchr('39')s 5D model, the linguistic validity, content validity and construct validity were tested on questions. The reliability of the questionnaire was evaluated using test-retest methods and Cronbachchr('39')s alpha coefficient and data were analyzed using the software SPSS 18.
Results: In studying content validity, the content validity index and total content validity ratio were obtained equal to 0.91 and 0.87, respectively. Confirmatory factor analysis of the questionnaire was evaluated, and KMO and Bartlett’s coefficients were obtained equal to 0.807 and 5237.791, respectively. In addition, factor analysis confirmed five factors in the study (including priority to safety, leadership, responsibility, safety integrity and learning), which accounted for 69.813% of the total variance. The results showed that the final questionnaire is reliable (α=0.902) and repeatable (ICC=0.899). There was a significant correlation between dimensions of the safety culture questionnaire (p<0.01).
Conclusion: The results of this study showed that a safety culture questionnaire that is designed according to the 5D model of the International Atomic Energy Agency has acceptable reliability and validity for measuring the safety culture in an oil and gas exploitation company. This tool can be effective in promoting safety culture in high-risk industries.
