All samples were selected randomly. The validity of the questionnaire was determined by statistical methods such as exploratory factor analysis, confirmatory factor analysis, and the heterogeneity between questions. Also, the Cronbach's alpha was used in order to investigate the reliability of the questionnaire.   Results: The results of exploratory factor analysis showed three factors including decision making, control, and incentives explained 66 percent of the total variance. Confirmatory factor analysis represented the appropriate fitness of information with a three-component structure (P<0.001, df = 2, 2 = 5.36, CFI = 0.957, RMSEA = 0.089). The Cronbach's alpha coefficient was higher than 0.7 for all three factors.   Conclusion : In this research, decision making was an important factor in measuring safety leadership.
