title: [Structural equation model analysis of relationship between occupational stress and work ability].
abstract: OBJECTIVE
  To construct the structural equation models of occupational stress and work ability to analyze the factor influencing work ability.
  
  
  METHODS
  A test of occupational stress and work ability was carried out with revised occupational stress inventory (OSI-R) and work ability index (WAI) for 2041 workers. And structural equation model was used to analyze their relationship.
  
  
  RESULTS
  The main factors influencing the work ability included the role insufficiency, psychological strain, physical strain, vocational strain. Rational/cognitive, education, income, recreation and self-care had some influence on the work ability, and they correlated positively with the work ability. And age, work age, role ambiguity and physical environment correlated inversely with the work ability.
  
  
  CONCLUSIONS
  The work ability of physical laborers can be improved with adjusting occupational stressor and improving the status of maladjustment, and the structural equation model can be used to study occupational medicine.
