摘要:Introduction: Maslach Burnout Inventory (MBI) (Maslach & Jackson, 1981) is the most commonly used measure of burnout among people from different backgrounds and professions. The educator survey of MBI is the version designed for studying burnout among those engaged in the teaching profession. Methods: MBI has been translated into various languages and its factor structure has been examined in many studies. This study examined the factorial structure of the Persian version of MBI through exploratory and confirmatory factor analyses among 570 Iranian EFL teachers. Results: The findings of the study confirmed the appropriacy of the original three-factor model as proposed by Maslach and Jackson for the Persian version of the MBI. Conclusion: The results of this study indicate that the Persian version of MBI can be used in burnout research with Persian speaking Iranian participants.
