Brief Summary
Fatigue is one of main symptoms in multiple sclerosis, amyotrophic lateral sclerosis and other diseases with profound effect on quality of life and professional and social functioning. Not infrequent it is misdiagnosed as sleepiness or other symptom. Fatigue severity scale is a time efficient and easy to apply instrument to assess the impact of fatigue on patient's life. The aim of this study is to validate the Polish-language version of the Fatigue Severity Scale.

Outcome Measures
Primary Outcomes (3)
Internal Consistency
Consistency between particular items of Polish language version of the Fatigue Severity Scale will be evaluated using Cronbach alfa test. The score of the Polish language version of the Fatigue Severity Scale ranges between 9 and 63 with higher scores meaning a worse outcome.
Through study completion, an average of 1 year
Validity
Validity will be tested by calculating the correlation of Polish language version of the Fatigue Severity Scale score with scores of Polish-language version of Modified Fatigue Impact Scale. The score of the Polish language version of the Fatigue Severity Scale ranges between 9 and 63 with higher scores meaning a worse outcome. The score of the Modified Fatigue Impact Scale ranges between 0 and 84 with higher scores meaning a worse outcome.
Through study completion, an average of 1 year
Reliability
Reliability will be tested by calculating the correlation between Polish language version of the Fatigue Severity Scale scores from the 1st and 2nd administration in the randomly selected subgroup of patients and controls. The score of the Polish language version of the Fatigue Severity Scale ranges between 9 and 63 with higher scores meaning a worse outcome.
Through study completion, an average of 1 year
Secondary Outcomes (4)
Impact of fatigue on quality of life - index
Through study completion, an average of 1 year
Impact of fatigue on quality of life - visual analogue scale
Through study completion, an average of 1 year

Through study completion, an average of 1 year
Difference in fatigue level between patients and controls
Through study completion, an average of 1 year
Study Arms (2)
Patients
Both sexes, aged 18 or older. The group will include 80 patients with multiple sclerosis, 80 patients with amyotrophic lateral sclerosis and 50 survivors of ischemic stroke
Control
Both sexes, aged 18 or older. The group will include 100 healthy controls.
Interventions
Testing with following Questionnaires: pFSS, Polish-language version of Modified Fatigue Impact Scale, Visual Analogue Scale of Fatigue, EQ-5D-5L (EuroQol-5 dimension) questionnaire, Beck Depression Inventory II. In randomly selected 30 patients and 20 controls questionnaires will be administered twice with two weeks interval to assess the test-retest reliability.
Eligibility Criteria
Participants will be recruited from the neurologic ambulatories and neurologic clinics of Jagiellonian University Medical College in Cracow and of Institute of Psychiatry and Neurology in Warsaw. Healthy controls will be recruited from personel of those facitlites as well as from the relatives of members of research team.
You may qualify if:
- Diagnosis of definite multiple sclerosis or definite, laboratory-supported multiple sclerosis, or definite amyotrophic lateral sclerosis, or probable amyotrophic lateral sclerosis or probable, laboratory supported amyotrophic lateral sclerosis or ischemic stroke or - for healthy controls - lack of diseases, pharmacotherapy or habits, which could induce abnormal tiredness
You may not qualify if:
- Presence of cognitive deficits or behavioral disorder, which could disturb participation in the study.
