    musculoskeletal disorders have a multi factorial etiology that includes not only physical risk factors but also psychosocial factors. this study aimed to investigate psychosocial risk factors and musculoskeletal symptoms among office workers of an iranian oil refinery and also to examine the subsequent effects of ergonomics intervention on musculoskeletal discomfort and psychosocial risk factors. in this study, 73 office workers as a case group and 61 office workers as a control group from an iranian oil refinery plant were randomly selected and examined. the nordic musculoskeletal disorders questionnaire and the persian version of the job content questionnaire (p-jcq) were used as collecting data tools before and after the interventional program. low back problem (28.8%) was found to be the most common problem among the office workers. significant differences found between prevalence rates of reported musculoskeletal in upper back, lower back and feet/ankle regions before and after intervention. our findings showed that psychosocial variables were not affected by the intervention. the only variables on the p-jcq that were significantly different pre/post intervention are the physical variables: physical job demands, physical exertion and physical isometric load. none of the other psychosocial variables were found to be significant. with the top management support, improvements in all office workstation components were made successfully. relevance to industry recently, changes in the nature of work draw increased attention to the relation between psychosocial factors and musculoskeletal disorders. the results of the current study indicate that a well conducted implementation of an interventional program can lead to a decrease in musculoskeletal symptoms and to some extent in the psychosocial factors at work.
