|Short Description of Instrument||
Purpose: The questionnaire contains 14 items that are rated on a numeric rating scale; two additional items contain multiple choice responses. The questionnaire assesses severity, distress, degree of interference in activities of daily living (ADL) and timing of fatigue. The scoring procedure includes calculation of the "Global Fatigue Index" (GFI), ranging from 1–50 with higher scores indicating more severe fatigue.
The MAF scale is easy to administer and score, and is relatively short in length. Items that do not apply can be omitted, making it a more accurate assessment of the impact of fatigue on ADL.
Comments: No universally accepted cut-off point to indicate severity of fatigue; dividing the GFI scores into quartiles indicating "no," "light," "moderate" and "severe" fatigue.
Translation: The MAF was originally developed in US English. Several language-versions are available at the MAPI Research Institute (Lyon, France). To gain access to and information about a translated version contact MAPI at their website at http://mapigroup.com/.
Administration: The MAF is self-administered and takes less than five minutes to complete.
Permission to Use and Copyright: There is no charge for individual use of the MAF. Colleagues in industry who would like to use the MAF may be charged a nominal fee.
Scores for the GFI range from 0 (no fatigue) to 50 (severe fatigue).
Calculating the GFI: Convert question #15 to a 0–10 scale by multiplying each score by 2.5 and then sum items #1, 2 and 3, average #s 4–14, and the converted item #15. If respondents select "no fatigue" on #1, assign a zero to items #2–16. Question #16 is not included in the GFI.
A higher score indicates more fatigue or impact on ADL.
Fatigue is an important issue with major influence on the ADL and quality of life in patients after SAH, as outlined by Kutlubaev et al. (2012). Measuring fatigue in SAH patients appears relevant for clinical use, as well as research. There are several instruments available to measure fatigue, of which the MAF and the Fatigue Severity Scale are the two most relevant. None of the two have been validated for use in SAH, but the MAF appears superior as it covers different aspects of fatigue including quantity, degree, distress, impact, and timing. For these reasons, the Swiss national standard of neuropsychological assessment after SAH includes the MAF.
