    Author: Xu B, Yang H, Chen B, Ni Z.
    Journal: Wei Sheng Yan Jiu; 2008 Jan; 37(1):59-62. PubMed ID: 18421866.
    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. CONCLUSION: 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.
