Abstract: Objective To examine the occupational stress among primary and middle school teachers,wardens,and video display terminal(VDT)operators and to compare the stress levels among the occupational groups.Methods The participants were randomly sampled and surveyed with Job Stress Survey(JSS)questionnaire.Results For the 851 primary and middle school teachers,the intensity of occupational stress of the males(2.34±0.51)was higher than that of the females(2.19±0.59,P < 0.05)and the intensity of occupational pressure of the males(1.96±0.51)was higher than that of the females(1.85±0.55,P < 0.05).The insufficient organizational support was observed in the participants aged more than 40 years(1.78±0.54),which was higher than that of the others.Parteicipants with senior job title had higher occupational stress than those with lower job titles.The influence factors of job stress were age,sex,and education.For the 875 wardens,the intensity of occupational stress of the males(2.13±0.13)was higher than that of the females(2.10±0.15,P < 0.05).Participants with bachelor or higher education(2.14±0.55)had higher occupational stress than those with college or lower education(P < 0.05).The intensity of occupational pressure of the males(1.66±0.15)was higher than that of the females(1.63±0.18,P < 0.05).Insufficient organizational support was observed in the participants aged more than 40 years(1.67±0.17),which was lower than that of the other participants.The participants with senior job title had lower organizational support.The influence factors of job stress were sex and education.For the 842 video terminal operators,the intensity of occupational stress of the males(2.24±0.15)was higher than that of the females(2.10±0.13).The influencing factor of job stress was age.Conclusion For the occupational populations surveyed,the intensity of occupational stress of the male is higher than that of the females and the influence factors of job stress are gender and education for primary and middle school teachers and age is the influence factor among video display terminal operators.
