Tai Chi for treating cancer-related fatigue: A meta-analysis of randomized controlled trials

Table 5 Psychometric properties and applicability of multidimensional fatigue Scales in cancer-related fatigue assessment

Scale	Items	Score range	Domains assessed	Reliability (α)	Characteristics
CFS[27-31]	15	0-60	Physical, affective, and cognitive	0.88	Describes the fatigue of current situation
BFI[27-31]	9	0-10 per subscale	Fatigue intensity	0.96	Examines fatigue in the previous 24 hours
RPFS[27-31]	22	0-10 per subscale	Behavioural/intensity, cognitive, affective and sensory	0.97	Multidimensional quantitative assessment reflects the complexity of patient fatigue and its impact on life. Addresses CRF's dual physical-cognitive pathology
RPFS-CV[27-31]	22	0-10 per subscale		0.91
MFSI-SF[27-31]	30	0-4 per subscale	General, physical, Emotional, mental and Vigor	0.87-0.96	Ease of use and scoring are of a moderate level

CRF: Cancer-related fatigue; CFS: Cancer fatigue scale; BFI: Brief fatigue inventory; RPFS: Revised piper fatigue scale; RPFS-CV: Revised piper fatigue scale-Chinese version; MFSI-SF: Multidimensional fatigue symptom inventory-short form.
