  Background: Several studies suggest the existence of an effective relationship between individuals’characteristics and important factors such as occupational and organizational performance, job satisfaction, organizational commitment, and etc. This study was designed based on the dimensions of personality (introversion /extroversion) of managers of Iran University of Medical Sciences at three levels (executive, middle and senior)with their career success rate.

  Methods :This was a cross-sectional descriptive study, whose population was all managers of Iran University of Medical Sciences. To collect data, two valid and reliable questionnaires were used. The first questionnaire assessed personality characteristics of each director, and the second measured occupational success. Related tests such as Pearson correlation test and independent comparison (independent t-test) at a significance level of 0.05 were used for data analysis.

  Results :Findings revealed no significant relationship between variables of introversion and extroversion and occupational success among the senior managers, (p> 0.05). However, there was adirect but incomplete relationship between introversion and extroversion, which correlated with job success among middle and executives managers.

  Conclusion :It seems that in all three levels of managers, if the managers communicated more with employees and if the subject of communication was more of executive nature, the correlation rate would increase between extroversion and introversion with job success variables. Therefore, it is suggested to give attention to organizational interaction and communication, and contingency variables such as organization condition,structure, formality and complexity.
