Table 5:
Multiple item multidimensional fatigue scales.
| Scale | No. of items | Characteristics | Reliability and validity | Population | Dimension |
|---|---|---|---|---|---|
| Cancer fatigue scale (numerical rating scale)[20,23,26] | 15 | Describes the fatigue of current situation. Less than 2–3 min to complete | Internal consistency is 0.88 Construct and convergent validity established |
Mixed cancers in different stages | Physical, affectiveand cognitive |
| Cancerrelated fatigue distress scale (Likert’s scale)[20,23] |
20 | Determines the distress related to fatigue over the past 7 days. Ten minutes to complete | Internal consistency is 0.98 Concurrent and construct validity established CVI=0.6–1.00 |
Breast cancer population receiving chemotherapy | Physical, social, psychological and spiritual distress |
| Lee fatigue scale/VAS fatigue (numerical rating scale)[20,22] | 13 | Simple and easy administration and scoring Psychometric properties are minimal | Internal consistency is 0.91 Convergent validity is established |
Sleep disorder patients | Energy and fatigue |
| Chalder fatigue scale/fatigue questionnaire (Likert’s scale)[20-22] | 11 | Use of scale and scoring is easy. Bimodal scoring and high ceiling effect can be seen | Internal consistency is 0.88–0.9 Convergent validity established. |
General population | Physical and mental |
| Multidimensional fatigue inventory MFI (Likert’s scale)[20,22,23] |
20 | Examines fatigue over the previous 24 h. Need not more than 10 min to finish | Internal consistency is 0.84 Convergent and discriminant validity is established |
Mixed cancer population | Cognitive, physical and emotional |
| Multidimensional fatigue symptom inventory MFSI (Likert’s scale)[22,23] | 30 | Ease of use and scoring are of moderate level. Requires 10 min to complete the inventory | Internal consistency is 0.87–0.96. Convergent, concurrent and discriminant validity established | Breast cancer population | Cognitive, physical and mental |
| Fatigue symptom inventory FSI (numerical rating scale)[22,23] | 13 | Frequency, severity and disturbance in life associated with fatigue are identified. Five minutes to complete the inventory | Internal consistency is 0.94 Convergent, concurrent and discriminant validity is established |
Patients undergoing treatment for breast cancer | Physical and mental |
| Piper fatigue scale revised PFR (Likert’s scale)[20,22,23] | 22 | Examines the current state of fatigue. Takes 5 min to administer it. Most commonly used scale in cancer as well as healthy individuals | Internal consistency is 0.97 Convergent validity, content validity and construct validity is established |
Patients with breast cancer | Behavioural/intensity, cognitive, affective and sensory |
| Schwartz cancer fatigue scale (Likert’s scale)[20,22,23] | 28 | Evaluate the fatigue over the past 2–3 days. Four minutes to complete the scale |
Internal consistency is 0.96 Convergent and discriminant validity established |
People with mixed cancers | Physical, cognitive and emotional |
| Fatigue assessment questionnaire (4point rating scale)[20,26,27] | 20 | Measure the fatigue over the past week. Unknown time to finish it | Internal consistency is 0.95 Validity established with correlation |
People with mixed cancer | Physical, cognitive and affective |
| Patient Reported Outcome Measure Information System Cancer Fatigue Short Form 3 (Likert’s scale)[23] | 7 | Examines the fatigue over the past 7 days. Undetermined time to complete the test Easy to administer and score |
Internal consistency is 0.87–0.88 Convergent and discriminant validity is established |
Population with haematological malignancies and prostate cancer | Fatigue intensity and severity including the disruption in daily activities |
| Multidimensional assessment of fatigue (numerical rating scale)[20,22] | 16 | Prepared from the piper fatigue scale (original version). Used for population with various disease including cancer. Fifteen items are used to assess global fatigue index. Five minutes to complete | Internal consistency is 0.88 Content validity is established. No appropriate construct validity established |
Initially done in arthritis patients later done in mixed cancer population | Severity, distress, disruption in ADLs and frequency |
| Fatigue and functional impact scale (Likert’s scale)[28,29] |
8 | Easy scoring and administration. 2–3 min to complete | Internal consistency is 0.9 Content and construct validity established |
Mixed cancer people receiving chemotherapy | Fatigue and its impact |
