Background: Nursing is a critical job in the health care system. However, nurses suffering from poor job conditions suffer from job dissatisfaction, eventually causing burnout. This is a very important concern for the health care system because the turnover of nurses leads to a waste of money and time of this system. Therefore, nurse managers need to find a way to measure and reduce the burnout. The Maslach Burnout Inventory-Human Services Survey (MBI-HSS) is a famous inventory to measure the job burnout in human services. This study aimed to measure the validity and reliability of the Persian version of MBI-HSS. Materials and Methods: This study was conducted in two hospitals of Fasa University of Medical Sciences, Fars Province, Iran, in July 2017. Nurses participated with their own discretion in this study and filled the MBI-HSS themselves. The questionnaire consisted of 22 items comprising three dimensions. Exploratory factor analysis and Cronbach's alpha were performed in this study using Stata software, version 12. Results: Overall, 200 nurses were included in this study, with a mean age of 29.48 +/- 6 years. The result of the exploratory factor analysis showed that the weight of each item in its own dimension was greater than 0.4 or another dimension. Also, the Cronbach's alpha for 3 dimensions was greater than 0.7. Conclusions: Our study showed that the Persian version of MBI-HSS has sufficient validity and reliability, similar to that of the original version, for the measurement of burnout in Persian speakers of human services workers.
