Summary

- measure
- Multidimensional Fatigue Inventory (MFI-20)
- timeFrame
- 5 minutes
- description
- MFI-20 is a self-reported questionnaire that measures fatigue severity. It contains 20 items and consists of five fatigue domains: mental fatigue, reduced motivation, reduced activity, physical fatigue and general fatigue. The response options consist of five check boxes ranging from "Yes, that is true" to "No, that is not true". The scores in each domain range from 4 to 20, with higher scores indicating higher levels of fatigue. A total fatigue score for all five domains is not used. MFI-20 has been used in several clinical and healthy populations.
Secondary outcomes (4)
- measure
- The short International Physical Activity Questionnaire (IPAQ)
- timeFrame
- 3 minutes
- description
- IPAQ short form is used to measure self-reported time spent on physical activity and sedentary behavior. The questionnaire measures four intensity levels of physical activity from none (sedentary) to strenuous physical activity. Patients are asked to report number of hours and minutes per day on the different activity levels.
