To examine the part played by psychological factors in complaints about visual health reported by banking officers who work at video display terminals (VDTs).
Out of a population of 385 bank workers, a group of 212 subjects without organic visual disturbances (as determined by ophthalmological examination) who share a work environment and job duties was selected. Three questionnaires were administered to these subjects: (a) the NIOSH job stress questionnaire; (b) a questionnaire investigating subjective discomfort related to environmental and lighting conditions of the workplace; (c) a questionnaire on the existence of oculovisual disturbances. Correlation and multiple regression analyses were performed to examine for the presence of predictors of asthenopia.
Social support, group conflict, self esteem, work satisfaction, and underuse of skills were found to be predictors of visual complaints; social support played a part also as a moderating factor in the stress and strain model; this model accounted for 30% of the variance. Subjective environmental factors, although in some cases significantly correlated with asthenopia, were not found to be strong predictors of the symptoms.
Some part of the complaints about visual health reported by VDT workers are likely indirect expressions of psychological discomfort related to working conditions.
探讨心理因素在视频显示终端（VDT）工作的银行职员所报告的视觉健康问题中所起的作用。
在385名银行工作人员中，选取了212名无器质性视觉障碍（经眼科检查确定）且工作环境和工作职责相同的受试者。向这些受试者发放了三份问卷：（a）美国国家职业安全与健康研究所（NIOSH）工作压力问卷；（b）一份调查与工作场所环境和光照条件相关的主观不适的问卷；（c）一份关于是否存在眼视觉障碍的问卷。进行相关性和多元回归分析，以检查是否存在视疲劳的预测因素。
社会支持、群体冲突、自尊、工作满意度和技能未充分利用被发现是视觉问题的预测因素；社会支持在压力和应变模型中也作为一个调节因素发挥作用；该模型解释了30%的方差。主观环境因素虽然在某些情况下与视疲劳显著相关，但未被发现是这些症状的强预测因素。
VDT工作者报告的视觉健康问题的一部分可能是与工作条件相关的心理不适的间接表现。
