| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
CIS-fatigue is an eight-item subscale of CIS that measures subjective fatigue. The CIS consists of 20 statements on fatigue-related problems. These components were easy to interpret and were called subjective fatigue (eight items), concentration (five items), motivation (four items), and physical activity (three items). Twenty items provide a total CIS20R score, including four subscale scores for subjective fatigue experience (eight items), concentration (five items), motivation (four items), and physical activity levels (three items). The CIS-fatigue uses eight items. Each item is scored on a seven-point Likert scale. |
| Number of Items | 8 item |

| PRACTICAL APPLICATION | |
| Method of administration | Self-administered |
| Recommendations to score |
The CIS consists of 20 statements on fatigue-related problems respondents might have experienced in the past 2 weeks. A Likert scoring scheme is used. With each statement, respondents indicate a score from 1 to 7, indicating either yes, that is true or no, that is not true. |
| Score Interpretation | Higher punctuation indicates higher fatigue |
| Cut-off points | Below 27 = normal experience of fatigue, 27-34 = moderate fatigue, >35 = severe fatigue(persistent severe fatigue) |
