We tested whether a short 12‑question survey called the Burnout Assessment Tool (BAT‑12) measures burnout in the same way in many different countries. We used data from 29,433 working adults in 29 countries across six continents. The results showed that the questions worked very similarly across countries, which means scores can be compared fairly between countries. In other words, the BAT‑12 is a reliable way to measure an overall (global) level of burnout based on four main symptom areas: exhaustion, mental distance from work, emotional problems, and cognitive problems (e.g., concentration or memory). Because it is brief and works well across cultures, the BAT‑12 can be used in (multinational) organizations around the globe and in international research to monitor burnout and to support the design and evaluation of burnout prevention and intervention programs (download full paper).
