Abstract
Background: Job stress is one of the basic problems in industrial that can underlie a number of problems such as cardiovascular disease, musculoskeletal diseases, early retirement to employees. On the other hand early retirement from workplace has increased, is one of the problems of today's industries.

The aim of This study is determine the relationship between job stress score, work ability and educational level in refinery workers.
Methods: This is a cross-sectional study in which 171 workers in refinery who were working in different occupational groups participated. Based on appropriate assignment sampling, 33 office workers, 69 operational workers, and 69 maintenance workers, respectively, were invited to participate in this study. Two questionnaires including work related-stress and WAI were filled in. Finally, the information was analyzed using the SPSS-20 and statistic tests namely, Pearson correlation coefficient, ANOVA and t-test.
Results: Analysis showed that 86% and 14% participants had extreme and moderate stress, respectively. Average score of stress and standard deviation was 158.7±17.3 that was in extreme stress range. Average score and standard deviation of WAI questionnaire were 37.18 and 3.86 respectively. That placed in a good range. Pearson correlation coefficient showed that WAI score had significant reversed relationship with a score of stress.
Conclusion: Stress is one of the most important factors that influence the ability of employees, so learning to cope with stress in order to maintain and enhance the ability of staff is recommend.

Abstract
Introduction: Firefighters are exposed to different chemical and physical hazards and experience a significant number of accidents and injuries. Therefore, they are known as a high-risk group for post-traumatic stress disorder (PTSD). The aim of this study was to determine the prevalence of post-traumatic stress disorder among firefighters in Isfahan city.
Methods: Subjects were 261 male firefighters of Isfahan city (mean age: 37.5±6.98 years). In this study, three standard self-report scales including Post trauma Symptoms Scale (PTSS-10), Impact of Event Scale (IES-15) and DSM-IV criteria were used. The data were analyzed by SPSS (ver. 20) using Pearson’s correlation test, chi-square test, t-test and Cronbach’s alpha coefficient.
Results: The mean (± SD) score of Impact of Event Scale, Post trauma Symptoms Scale and DSM-IV was criteria 32.86 ± 14.46, 3.3 ± 3.18 and 6.8 ± 4.0, respectively. Cronbach's alpha coefficient for the three scales of DSM-IV, Impact of Event Scale and Post trauma Symptoms Scale was 0.83, 0.843 and 0.916, respectively. Results showed that mean scores of IES had a significant relationship with age (P=0.001) and work experience (P=0.001). Also a mean score of PTSS had a significant relationship with age (P=0.03) and work experience (P=0.01).
Conclusion: IES-15, PTSS-10 and DSM-IV can be useful tools to assess the prevalence of PTSD and the Persian version of these scales was valid and reliable. Based on the results, the probability of PTSD among firefighters was high, that can negatively affect on their habits, attitudes, interests and lifestyles. Therefore, it is necessary to take preventive and treatment measures of PTSD should be proposed and implemented.

Abstract
Introduction: Investigations show that the scattering of accidents in individuals is not the same, and three quarters of all accident occur to one quarter of accident prone individuals. The aim of the study was to design and validate a questionnaire for screening out the accident prone individuals.
Methods: This study in 5 stages of item generation, content validity assessment, reliability, construct validity, and criterion validity was performed among 230 workers who had and who had not experienced accident in 19 industries of Isfahan, Iran. For data analysis SPSS and Amos 22 were used.
Results: 195 items were identified during item generation stage. In content validity evaluation stage 13 items were removed, 15 items were modified and 79 items were merged and convered to 14 items. Internal consistency (Cronbach's alpha) of the remained items was 0.86. The results of confirmed validation showed that comparative fit index was acceptable. (CFI=0.99, GFI=0.96, RMSEA=0.066, RMR= 0.022). T test showed that the mean scores of the workers who had accident were significantly higher than the workers who had not experienced accident (p<0.001).
Conclusion: The result of confirmed validation showed that there is a good agreement between the proposed model and the field data. Reliability and construct validity showed that the current questionnaire is suitable for screening out the accident prone individuals.
