About this trial

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.

Eligibility criteria

This trial accepts healthy volunteers

Qualifiers

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

Disqualifiers

Presence of cognitive deficits or behavioral disorder, which could disturb participation in the study.

Trial population

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.

Treatments tested in this trial

  • Testing with Questionnaires

    Diagnostic test

    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.

Trial outcomes

Primary outcomes

1

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.

Time frame
Through study completion, an average of 1 year
2

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.

Time frame
Through study completion, an average of 1 year
3

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.

Time frame
Through study completion, an average of 1 year

Secondary outcomes

1

Impact of fatigue on quality of life - index

Correlation between Polish language version of the Fatigue Severity Scale score and the index score of EQ-5D-5L (EuroQol-5 dimension) questionnaire. 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 index score of EQ-5D-5L (EuroQol-5 dimension) questionnaire ranges between -0.59 to 1 with higher scores indicating better outcome.

Time frame
Through study completion, an average of 1 year
2

Impact of fatigue on quality of life - visual analogue scale

Correlation between Polish language version of the Fatigue Severity Scale score and the visual analogue scale score of EQ-5D-5L (EuroQol-5 dimension) questionnaire. 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 visual analogue scale score of EQ-5D-5L (EuroQol-5 dimension) questionnaire ranges between 0 to 100 with higher scores indicating better outcome.

Time frame
Through study completion, an average of 1 year
3

Impact of fatigue on depression

Correlation between Polish language version of the Fatigue Severity Scale score and score of Beck Depression Inventory II. 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 Beck Depression Inventory II ranges between 0 and 63 with higher scores indicating worse outcome.

Time frame
Through study completion, an average of 1 year
4

Difference in fatigue level between patients and controls

Difference in Polish language version of the Fatigue Severity Scale score between 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.

Time frame
Through study completion, an average of 1 year
