This research was conducted as following. First, the research investigated the stress score of civil engineering staff in 56 projects of the department of rural roads which were carried out from July 2020 to December 2020. The results revealed that out of the full score of 100.00 point, the sample group’s average stress score was 50.16 points. The median score was 49.00 point and the lowest and highest scores were 20.00 point and 80.00 point, respectively. Categorizing the sample group according to stress levels showed that the groups with severe stress, high stress, moderate stress, and low stress accounted for 22.80%, 45%, 29.30%, and 2.90%, respectively. Second, the study analyzed the relationship between individual and career factors and stress scores. It appeared that gender, family income, and job positions had a significant relationship with stress scores, at a statistical significance of 0.05. Third, the research created a multiple linear regression model to predict stress scores, for which five individual and career factors were selected for inclusion: having excess income (family income), working as a foreman or a civil engineer, being male (gender), being 41 to 50 years of age (age), and having to work seven days a week (the number of workdays per week). The predicting power of the aforementioned model was at 13.10 %.
