视屏显示终端作业者职业紧张及影响因素分析

目的 探讨视屏显示终端(VDT)作业者职业紧张程度、紧张反应及其影响因素。方法 应用职业紧张调查表(OSI-R)对某市302名视屏显示终端作业者及208名对照者进行对比研究。结果 VDT组职业任务总分及任务过重、责任感及工作环境子项得分较对照组高(P<0.01);紧张反应总分及业务、心理和躯体紧张反应子项得分高于对照组(P<0.01);应对资源总分及休闲、自我保健、社会支持及理性处事子项得分均低于对照组(P<0.01)。逐步回归分析结果显示,影响VDT作业紧张反应因素有任务冲突、责任感、工作环境、每天VDT作业时间、VDT作业工龄、社会支持和理性处事差异有统计学意义(P<0.05)。结论 VDT作业者视屏作业紧张和紧张反应显著增高。应采取有效措施缓解其紧张反应。

Occupational stress and influence factors of video display terminal operator

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.
