The MFIS-5 measures the impact of fatigue on cognitive, physical and psychosocial function—considered by some authors to be three important sub-scales—in patients with MS. It does not identify cases or non-cases of fatigue, unlike the Chalder Fatigue Scale 11, that was recently reviewed in this journal [ 4 ]. It is a self-administered questionnaire and begins with introductory statements about how fatigue can affect a person, what fatigue is and that, in medical conditions like MS, fatigue can occur more often and have a greater impact.
Patients are then asked to circle the one number from a 5-point Likert scoring system that best indicates how often fatigue has affected them during the past 4 weeks. The sum provides a total score from 0 to In practice, it is short and quick to administer and therefore practical to use in a clinic setting.
The FIS questionnaire is considered to be a widely used, robust and validated tool for patients presenting with chronic fatigue, MS, chronic obstructive pulmonary disease, primary biliary sclerosis and chronic hepatitis C infection [ 5 ].
The MFIS versions have been validated and accepted for use in patients with MS and in some other neurological-condition-defined patient groups, e. The MFIS also has various problems that result in limitations when interpreting the scores, particularly when trying to interpret what a change in score might mean and consideration of symptom confounders such as depression [ 9 ].

I have also found it useful in my assessment of patients with other conditions in which fatigue is a dominant symptom, e.
My patients have reported that it helps them to view their fatigue symptoms more objectively and assists them in monitoring their progress in managing these symptoms. Anecdotally, I have found that work ability levels improve as the score reduces.
I have also found, more rarely, that this can happen when the score is unchanged—perhaps indicative of better self-management techniques and outcomes, rather than absolute improvement in fatigue symptoms. My view is that it has the potential for wider use, beyond MS patient groups, although further research and development is needed to demonstrate its validity in other patient groups and to address some of the limitations arising when interpreting the score and any score changes between tests.

Younger age, female sex, and high number of awakenings and arousals predict fatigue in patients with sleep disorders: a retrospective polysomnographic observational study Background: The Fatigue Severity Scale FSS is widely used to assess fatigue , not only in the context of multiple sclerosis-related fatigue , but also in many other medical conditions.
Some polysomnographic studies have shown high FSS values in sleep-disordered patients without multiple sclerosis. The Modified Fatigue Impact Scale MFIS has increasingly been used in order to assess fatigue , but polysomnographic data investigating sleep-disordered patients are thus far unavailable. Moreover, the pathophysiological link between sleep architecture and fatigue measured with the MFIS and the FSS has not been previously investigated.
They were asked to comment on the relevance of the item set for MND and whether or not the items were understandable. The qualitative methodology is described in further detail elsewhere [8]. In addition, the MND qualitative data were compared to previously derived themes in MS for the emergence of new themes. Patients were eligible to enter the study irrespective of age, sex, and disease sub-type or disability status.
Two to four weeks after completing the first questionnaire patients were invited to complete a second question- naire to assess test-retest reliability. Psychometric Properties of the Persian Version of the Fatigue Impact Scale FIS-P in Patients with Multiple Sclerosis status, and its widespread presence among MS patients, access to an accurate qualitative and quantitative fatigue assessment tool in the assessment and management of its symptom is required 7,26, Access to such a tool would enable clinicians and researchers to more accurately evaluate the effects of treatment interventions on fatigue control.
To our knowledge, the translated and culturally adapted Persian version of the FIS has not yet been assessed for validity and reliability. The current study was conducted to assess this tool. FIS and FSS are the most common and accurate tests used both in research and clinical settings worldwide 7, FIS Fisk et al.
