Primary outcome measure(s)
Internal Consistency — Through study completion, an average of 1 year 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.
Validity — Through study completion, an average of 1 year 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.
Reliability — Through study completion, an average of 1 year 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.
