VDT OPERATORS' OCCUPATIONAL STRESS AND PSYCHOPHYSICAL STATE

进行了VDT作业人员职业应激及心身状态的调查研究。结果初步显示VDT作业本身独特的职业性质、工作环境和作业需求形成了VDT作业的主要应激源,其作业时间和作业负荷较大者产生了较高的职业性紧张度。VDT作业人员对工作满意程度较差。心理健康水平评价显示该作业人员心理健康水平较对照人员为低,尤其表现在强迫和抑郁两个心理因子方面。心身疾患评价提示VDT作业可能会给作业人员带来一定的心理—生理障碍。本研究尚未发现VDT对作业人员植物神经功能的不良影响。

VDT operators' occupational stress and psy-chophysical state were studied. The resultsshowed that the nature, environment and require-ments of VDT operation shaped the major occupa-tional stress in VDT operation. The longer VDTworking hours and more workloads gave the opera-tors more occupational strains. VDT operators hada lower satisfactory level to the job and lower psy-chological health level than contral group, espe-cially on obsession and depression. VDT operationperhaps gave the operators some kinds of psycho-physiological troubles. We did not find there wereharmful effects of VDT on the operators' autonom-ic nervous functions.
