How long does it take to complete and how many items are included?
It includes 20 items and typically takes about 4 minutes to complete.
What time period should be considered when answering?
Answer based on recent experience, using the timeframe stated in the item wording. If no timeframe is stated, use how things have been lately.
How should responses be selected?
Select the response option that best matches the current level of fatigue or energy for each statement. Use the full range of options and avoid leaving items blank when possible.

Multidimensional Fatigue Inventory (MFI-20) Test - Symptoms and Signs
Fatigue can be multifactorial, and the Multidimensional Fatigue Inventory (MFI-20) is a brief self-report measure designed to characterize fatigue across several domains. It helps differentiate patterns of physical, mental, and motivational fatigue experiences.
The instrument includes 20 items and is typically completed in about 4 minutes. Item content samples common fatigue-related complaints, supporting domain-level scoring that can inform clinical documentation and treatment planning. Smets, E. is commonly cited in relation to its development.
In clinical and research settings, the Multidimensional Fatigue Inventory (MFI-20) may be used to monitor fatigue severity and profile over time, including in medical illness, recovery, or rehabilitation contexts, as part of a broader assessment of symptoms and functioning.
