The Brief Fatigue Inventory (BFI) is used to rapidly assess the severity and impact of cancer-related fatigue. An increasing focus on cancer-related fatigue emphasized the need for sensitive tools to assess this most frequently reported symptom. The six interference items correlate with standard quality-of-life measures.
|BFI Fatigue Items||BFI Interference Items|
|Fatigue right now||General activity|
|Usual fatigue in last 24 hours||Mood|
|Worst fatigue in last 24 hours||Walking ability|
|Normal work (including housework)|
|Relations with other people|
|Enjoyment of life|
Order the BFI
- Purpose: To assess the severity of fatigue and the impact of fatigue on daily functioning
- Population: Patients with fatigue due to cancer and cancer treatment
- Assessment Areas: Severity of fatigue and the impact of fatigue on daily functioning in the past 24 hours
- Method: Self-report, interview with research staff, or interactive voice response system (IVR)
- Time required: Five minutes
- Scoring: A global fatigue score can be obtained by averaging all the items on the BFI
- Reliability: Cronbach alpha reliability ranges from 0.82 to 0.97

Fatigue is the symptom most frequently reported by cancer patients. It is often the most distressing symptom and causes the most interference with daily living.
