Abstract: Objective To investigate occupational stress,strain and influence factors in video display terminal operators in banks.Methods Changes in occupational stress was measured with revised occupational stress inventory(OSI-R).Results (1)The score of occupational role and strain in the g roup of VDT are significantly higher than those in the controls,where as the scores of the personal resources are lower in VDT operators(P<0.01).(2)The stepwise regression shows that the primary influential factors of personal stress were role boundary,physical environment,responsibility,operating times of VDT in day,working years of VDT,social support and rational cognitive coping(P<0.05).Conclusion The stress and strain in the VDT groups are obviously increased.Efficient measures should be taken to reduce their stress and strain in order to promote and protect their health.
