摘　　要：目的　探讨不同劳动类型的劳动者脑力能力和职业心理紧张间的关系。方法　现况调查,以随机整群抽样的方法对某地区485名劳动者进行职业紧张问卷(Occupational Stress Questionnaire, OSQ)调查和脑力能力(包括客观测量和主观自评)的测定。结果　劳动者心理紧张强度和脑力能力主、客观指标在不同文化程度组和劳动类型组差异均有显著性(P<0.05);高紧张强度组脑力能力主、客观指标得分均低于其他两组(P<0.05);心理紧张强度与劳动者脑力能力主、客观指标均呈显著负相关关系(P<0.01)。结论　文化程度、劳动类型和心理紧张强度与劳动者脑力能力有密切关系,高度的紧张会导致脑力能力的下降。Objective To investigate the relationship between occupational psychological stress and brain ability among workers of different work types. Methods A cross-sectional study was conducted among randomly chosen 485 municipal workers with Occupational Stress Questionnaire (OSQ) to test their Mental Function Index (MFI, including short memory, decode and AYP) and autocritical brain ability respectively.Results There were significant differences (P<0.01) in Psychological Stress Intensity (PSI), MFI and autocritical brain ability of workers among different educational level groups and work type groups respectively. MFI and autocritical brain ability were significantly and negatively correlated with PSI (P<0.01). Conclusion Educational level, work type and PSI could have obvious effects on brain ability of physical and mental workers. It was shown that excess stress may depress brain ability on the workers.
