VDT OPERATORS' OCCUPATIONAL STRESS AND PSYCHOPHYSICAL STATE / 西安交通大学学报(医学版)

ABSTRACT

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.
