There has been a growing interest among scholars in intangible organizational capitals in recent years. Present research is primarily concerned with investigating the relationship of psychological capital with quality of work life and the modifying effect of job stress on the relationship between the first two variables. The required data was collected in the winter of ۲۰۱۶ through the distributed questionnaires among employees of Nilpar Companies operating in the office chair and furniture industry, based on stratified sampling. Because of limited number of the population (۴۳۵), to determine the sample size, the Cochran formula in limited population was used. Then, based on the sample size and convenience sampling, the questionnaires were distributed. Finally, from the collected questionnaires, ۲۰۴ thereof were considered valid and used in subsequent analyses. To examine the relationship between the variables by test of the hypotheses, multivariate regression and structural equation modeling (path analysis) were performed. The results suggested that at ۹۵ percent confidence there was a positive and statistically significant relationship between psychological capital and quality of work life. In addition, a negative and statistically significant relationship was found that job stress was negatively correlated to psychological capital and quality of work life which was significant in both instances.
