Four research questions and four research objectives are solved by implementing suitable descriptive and inferential statistical analyses. All of the main hypotheses of the present study examined used regression analyses. The results of the study show that there are significant negative relationship between all three types of role stressor (i.e. role ambiguity, role conflict and role overload) and organizational commitment. Furthermore the study reveals that only role ambiguity and role overload have
