摘要:This study aimed to determine the effective factors in organizational commitment and the relationship between happiness and organizational commitment among managers of District Four of Islamic Azad University in Iran. The research methodology consisted of a descriptive survey and a correlation study, with data gathered through questionnaires and interviews. All the 590 senior, middle, and supervisory managers of District Four of the aforementioned university were included in the sample. The reliability and the validity of the instruments used were confirmed by experts and professors, as they were by Runback's alpha coefficient. A reliability coefficient of 0.71 for the questionnaires was obtained according to the calculations. The results of the survey of 259 managers who were selected at random showed that, as a whole, there was a significant relationship between organizational commitment and happiness, especially between happiness, efficiency, and organizational commitment. The other dimensions of happiness did not show a significant relationship. What seems important is that organizational commitment and increasing productivity have a certain relationship with happiness. Thus, this relationship must be given serious consideration in efforts to improve organizational efficiency.
