Abstract

Objective: A study was undertaken to test the psychometric properties of the Fatigue Severity Scale (FSS), and to explore the relationship between fatigue and sociodemographic variables in the general population. Method: A national representative sample of 1893 respondents was randomly selected from a pool of 4,000 Norwegians aged 19—81 years. A mailed questionnaire that included the FSS was used to measure fatigue severity. Results: The FSS showed satisfactory internal consistency (Cronbach's alpha 0.88). The prevalence of high fatigue (FSS score>=5) was 23.1% in the total sample. More women (26.2%) than men (19.8%) experienced high fatigue (p=0.004). Respondents with chronic illness (more than six months) reported a higher mean (M=4.69, SD=1.35) than the rest of the sample (M=3.67, SD=1.17) (p<0.001). An inverse correlation was found between fatigue and level of formal education (r=0.20, p<0.001). Conclusion: The psychometric properties of the Norwegian version of FSS were satisfactory. To avoid over-diagnosing people for high level of fatigue, the threshold for high fatigue probably should be 5 on the FSS scale instead of 4 as had been suggested originally, but further validation of the cut-off point is needed.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
