Construction and Standardization of Performance Evaluation test of Health, Safety and Environment Management Systems of Industrial Sector Contractors

Performance appraisal has always been a fundamental and important process for all organizations, especially for the health, safety and environmental management systems of industrial contractors. The aim of the present study is to construct and determine the psychometric characteristics of the questionnaire of performance evaluation of health، safety and environmental management systems of steel contractors.

The method of this research is qualitative and quantitative. In the quantitative section، the statistical population included all professors who have research research on the subject، which were selected by the available samples. The collection method in the qualitative section included interviewing and reviewing existing articles. In the quantitative section، the statistical population included all of HSE experts who were selected by cluster sampling of 350 people based on Cochran's formula. The research information was collected through a researcher-made questionnaire based on the qualitative section. Content validation methods، convergence and factor analysis were used to evaluate the validity of the scale. The reliability of the scale was assessed by internal consistency and purity reliability methods. Descriptive and inferential statistical methods were used to analyze the data using SPSS software version 22 and LISREL version 8.

The results of exploratory factor analysis showed that the researcher-made questionnaire consisted of seven factors and its validity was in the range of 80 to 100% and reliability was obtained by Cronbach's alpha method of 0.91. The second-order confirmatory factor analysis also confirmed the seven-factor model. This questionnaire was implemented along with the short form of HSE performance evaluation scale for petrochemical contractors، which had a good reliability and validity with 65 items.

 In the present study, a model for evaluating the performance of health, safety and environment management systems of industrial contractors was presented. The developed items are able to evaluate the performance of health, safety and environment management systems of industrial sector contractors.
