摘要:The main goal of the universities is to train individuals who have sufficient knowledge and skills and who will receive high demand in business life with their strong academic staff. For this reason, it is very important that graduates with the necessary equipment and knowledge from the universities of the students who are the only hope for the future of the countries. This study explores the mediating role of psychological capital between organizational citizenship behavior and perceived organizational justice with the help of the structural equation model. In this respect, 6,643 questionnaires were sent to the academic staffs from 190 selected universities in the Republic of Turkey with random sampling method and the data were collected from 611 respondents. After analysis of data it has been found that organizational justice partially affects organizational citizenship behaviors and similarly it is found that psychological capital has partial influence on organizational citizenship behaviors. On the other hand, the result is that the psychological capital has a partial mediating effect on the model. It has been found that studies on the possibility that the psychological capital can be an intermediary variable are very limited. In this context, it is thought that this study can contribute to the literature.
