Development and Validation of a Safety Climate Scale for Manufacturing Industry

Background: This paper describes the development of a scale for measuring safety
climate. Methods: This study was conducted in six manufacturing companies in Iran. The
scale developed through conducting a literature review about the safety climate and
constructing a question pool. The number of items was reduced to 71 after performing a
screening process. Results: The result of content validity analysis showed that fifty-nine
items had excellent item content validity index (I-CVI ≥ 0.78) and content validity ratio (CVR
> 0.38). The exploratory factor analysis (EFA) resulted in eight safety climate dimensions.
The reliability value for the final 45 item scale was 0.96. The result of confirmatory factor
analysis (CFA) showed that the safety climate model is satisfactory. Conclusion: This study
produced a valid and reliable scale for measuring safety climate in manufacturing companies
