Maslach Burnout Inventory (MBI) is the gold-standard for measuring burnout, but the main problem is that it is not free. On the other hand, using free burnout questionnaires are always less reliable compared to the gold standard, of course. However, if you're able to accept this, there is this non-proprietary single-item measure, validated to serve as a reliable substitute for the Maslach Burnout Inventory Emotional Exhaustion (MBI:EE) in the healthcare setting [1]. The main advantage is that the questionnaire is free and easy to respond [2, 3]. It has been used in several previous studies on doctors [4–6].
