| DESCRIPTION OF THE INSTRUMENT | |
| Type Of Measure | Questionnaire |
| Brief Description |
MFSI is a measure designed to assess the principal manifestations of fatigue. The MFSI consists of both rationally and empirically derived subscales. The rationally derived subscales, which were developed based on expert assignment to categories, are designed to assess global, somatic, affective, cognitive, and behavioral manifestations of fatigue. The empirically derived subscales, which were developed using factor analysis, are considered to assess general, physical, emotional, and mental manifestations of fatigue as well as vigor (an estimate of the patient's energy level). The SF of the MFSI yields scores only for the empirically derived subscales; it may be used as a substitute for the MFSI when time constraints and scale length are of concern |

| Recommendations to score |
The MFSI can be scored for both the rationally derived and empirically derived scales. The scoring for the rationally derived scales is as follows: global scale = sum of items 26, 35, 43, 45, 52, 54, 60, 62, 70, 71, and 78 divided by 11, and somatic scale = sum of items 1, 4, 9, 12, 14, 16, 18, 20, 25, 27, 37, 38, 42, 48, 51, 57, 68, 73, 74, 79, 82 divided by 21. The scoring of MFSI-SF is as follows: general scale = sum of items 10, 12, 14, 17, 18, and 28; physical scale = sum of items 2, 4, 6, 16, 19, and 26; emotional scale = sum of items 3, 8, 13, 21, 23, and 30; mental scale = sum of items 1, 11, 15, 20, 25, and 27; vigor scale = sum of items 5, 7, 9, 22, 24, and 29; and the total score = (general + physical + emotional + mental) − vigor. |
| Score Interpretation | Higher scores indicate more fatigue. |
