The research purpose is to investigate whether mindfulness as a personal characteristic might be associated with higher levels of organizational citizenship behavior. To understand the nature of the association between Mindfulness (MAAS) & organizational citizenship behavior (OCB), possible mediating role of other variables such as job stress (JSS), & job satisfaction (IWS) were also assessed. The sample consists of employees at Eastern Mediterranean University, North Cyprus, (n= 196). A self-administered questionnaire was used, the data collection lasted for one month. Analysis of the data & hypothesis testing was conducted using SPSS v23 & SmartPLS. The positive association between mindfulness & organizational citizenship behavior was indirectly explained by job stress which is reduced by mindfulness & when it is lower leads to higher OCB. Whereas, job satisfaction is enhanced by mindfulness & when it is higher it leads to higher OCB. Mindfulness training may help to prepare the necessary context for the employees to have higher levels of organizational citizenship behavior. Furthermore, the results help us to have a better understanding of the mechanism by which mindfulness leads to higher organizational citizenship behavior.
