title: Determinants of job stress in chemical process industry: A factor analysis approach.
abstract: BACKGROUND
  Job stress is one of the active research domains in industrial safety research. The job stress can result in accidents and health related issues in workers in chemical process industries. Hence it is important to measure the level of job stress in workers so as to mitigate the same to avoid the worker's safety related problems in the industries.
  
  
  OBJECTIVE
  The objective of this study is to determine the job stress factors in the chemical process industry in Kerala state, India. This study also aims to propose a comprehensive model and an instrument framework for measuring job stress levels in the chemical process industries in Kerala, India.
  
  
  METHODS
  The data is collected through a questionnaire survey conducted in chemical process industries in Kerala. The collected data out of 1197 surveys is subjected to principal component and confirmatory factor analysis to develop the job stress factor structure.
  
  
  RESULTS
  The factor analysis revealed 8 factors that influence the job stress in process industries. It is also found that the job stress in employees is most influenced by role ambiguity and the least by work environment.
  
  
  CONCLUSIONS
  The study has developed an instrument framework towards measuring job stress utilizing exploratory factor analysis and structural equation modeling.
