Items are scored 1–5, with 10 [fatigue-]positively phrased items reverse scored (items 2, 5, 9, 10, 13, 14, 16, 17, 18, 19). In the final score, high scores represent more fatigue. Total score calculated for 5 subscales: - general fatigue (items 1, 5, 12, 16); - physical fatigue (items 2, 8, 14, 20); - reduced activity (items 3, 6, 10, 17); - reduced motivation (items 4, 9, 15, 18); - mental fatigue (items 7, 11, 13, 19).

You herewith have my permission to do so. Although I realize it depends on the trustworthiness of the end-user, I would prefer tasks including the MFI to be restricted to researchers en educators. I hope you helps. Kind regards, Ellen Smets Prof. dr.

Our understanding of the copyright status of the MFI-20 is: · It is copyrighted on the names of the authors. · It is free for academic use. May we ask if that is correct? CamCOPS is free and open-source software for capturing structured data relevant to psychiatry directly from patients, clinicians, and researchers. It was developed in the University of Cambridge, UK, and is in use for clinical and research purposes. Data flow is entirely under the control of the hosting institution. CamCOPS implements both open/free tasks and closed/restricted tasks using one of the following methods: · Open/free tasks are embedded into CamCOPS directly; this is our preferred method. · Some tasks may be permitted to some institutions but not others. These can be implemented via a public “skeleton” in CamCOPS (with no task content) and a “plugin” containing the task content (e.g. text for a questionnaire) that licensed users can add to their CamCOPS installation, converting the skeleton into a fully working copy. · Some closed tasks do not permit electronic reproduction. Sometimes, these still benefit from an electronic data capture “skeleton” that never includes task content, but is still preferable to paper capture and manual (laborious and error-prone) transcription. The electronic skeleton can then be used in conjunction with a licensed paper copy of the task. In addition, all CamCOPS tasks can be restricted if necessary according to flags that the end user can set: clinical use? Research use? Educational use? Commercial use? For example, a task can be restricted to noncommercial use only (though this relies on end-user honesty and end-user liability). Would it be permissible for us to incorporate the MFI-20 into CamCOPS, using one of the above methods? We’d be most grateful. Thank you for your time in considering this. If you have any questions or if there is anything I can clarify, please just let me know. Yours sincerely, Joel Parkinson [...] History ~~~~~~~ - Smets E, Garssen B, Bonke Bd, De Haes J (1995).

Application of the multidimensional fatigue inventory (MFI-20) in cancer patients receiving radiotherapy. *Br J Cancer* 73: 241-5. https://www.ncbi.nlm.nih.gov/pubmed/8546913 Modifications ~~~~~~~~~~~~~ - Original scoring (from 2019-07-19) was as follows: "Items are scored 1–5, with 10 positively phrased items reverse scored (items 2, 5, 9, 10, 13, 14, 16, 17, 18, 19). Total score calculated for 5 subscales: general fatigue (items 1, 5, 12, 16), physical fatigue (items 2, 8, 14, 20), reduced activity (items 7, 11, 13, 19), reduced motivation (items 3, 6, 10, 17), and mental fatigue (items 4, 9, 15, 18)." Per https://github.com/ucam-department-of-psychiatry/camcops/issues/199, from https://github.com/pjbulls, on 7 Sep 2021: The grouping of MFI-20 questions into categories (general, physical, motivation...) is not in line with literature, which almost invariably uses the following: - General [Fatigue] = items 1, 5, 12, 16 *[same as our original]* - Physical [Fatigue] = items 2, 8, 14, 20 *[same as our original]* - Reduced Activit[y] = items 3, 6, 10, 17 *[this list was "reduced motivation" previously]* - [Reduced] Motivation = items 4, 9, 15, 18 *[this list was "mental fatigue" previously]* - Mental [Fatigue] = items 7, 11, 13, 19 *[this list was "reduced activity" previously]* Example references include: - https://doi.org/10.1002/msc.124 = Goodchild et al. (2008), https://pubmed.ncbi.nlm.nih.gov/18085596/, esp. Table 3; - https://doi.org/10.1016/j.parkreldis.2012.01.024 = Elbers et al. (2012), https://pubmed.ncbi.nlm.nih.gov/22361576/, esp.

The changes are clearly correct and our previous version clearly wrong. Changes implemented 2021-10-07. No changes are made to the underlying data; this merely alters its presentation in summary views. Also (simultaneously) fixed minor typo: "keep my thought on it" --> "keep my thoughts on it" in Q7.
