ABSTRACT
ObjectiveTo study the relationship between occupational stress/sleep quality and job satisfaction of internet enterprise programmers， to explore the mediating effect of sleep quality between occupational stress and job satisfaction， and to provide a theoretical basis for taking effective measures to improve job satisfaction. MethodsA total of 271 programmers from an Internet company in Shanghai were investigated by job content questionnaire， Pittsburgh Sleep Index Scale and the third part of the McLean occupational stress questionnaire. The results were statistically analyzed ResultsThe positive rate of occupational stress of programmers in this enterprise was 66.7%， 34.3% of them had average sleep quality， 28.0% had poor sleep quality， and the score of job satisfaction was 47.70±6.78. Correlation analysis showed that the higher the occupational stress， the worse the sleep quality and the lower the job satisfaction. Effects of occupational stress and sleep quality on job satisfaction were both statistically significant. The total effect of occupational stress on job satisfaction was -0.35， and the mediating effect of sleep quality between occupational stress and job satisfaction was -0.04， accounting for 12.0% of the total effect. ConclusionSleep quality of internet enterprise programmers plays a partial mediating role between occupational stress and job satisfaction， and a series of measures such as improving sleep can be taken to improve programmer’s job satisfaction.
ABSTRACT
Objective@#To investigate the quality of life of the visual display terminal (VDT) operators in Hangzhou Internet enterprises and to analyze its influencing factors. @*Methods@#Through cluster sampling,, 944 employees were investigated by demographic and general health questions and the MOS 36-Item Short Form Health Survey Questionnaire from October to November in 2016 and carried out statistical analysis. @*Results@#VDT operators’ physical functioning, role-physical, bodily pain, general health, vitality, social functioning, role-emotional, mental health, physical component summary and mental component summary scores were (86.3±17.0) , (82.5±30.3) , (80.6±16.1) , (56.8±18.6) , (53.7±15.6) , (78.5±17.8) , (81.2±31.9) , (48.8±19.3) , (51.1±8.9) , (43.8±9.1) . Except physical functioning, role-physical and physical component summary scores, the scores of other scales and mental component summary were lower than the norm (P<0.05) . Multivariable logistic regression showed that vegetable intake, sleeping and physical exercise had an impact on the physical component summary score. The influential factors of mental component summary score included marital status, education, neck pain and health concerns. @*Conclusion@#We should pay attention to the quality of life of VDT operators in Internet enterprises, especially their mental health.
