Functional Assessment of Chronic Illness Therapy – Fatigue (FACIT-F)

The FACIT-Fatigue measures how much fatigue is affecting a person's daily life. Thirteen statements cover the experience directly — feeling weak, feeling listless, being too tired to eat, needing to sleep during the day, needing help with usual activities, and having to limit social activity because of tiredness.

Each is rated from not at all to very much over the past seven days, giving a subscale score from 0 to 52 where higher means less fatigue. It grew out of cancer-related anemia research in the 1990s but is now used well beyond oncology, particularly in rheumatoid arthritis, lupus, and other chronic conditions. It can be given on its own or alongside the FACT-G.

Learn More: The naming here causes real confusion. FACIT-F is a 40-item measure(the 27-item FACT-G plus the 13-item fatigue subscale). The FACIT-Fatigue Scale on its own is those 13 items. Most published research reporting "the FACIT-F" means the 13-item subscale, so check which one a study or chart is using.
