Psychometric properties of an Arabic version of the fatigue severity scale in patients with stroke

Background: Rigorous testing of the original Fatigue Severity Scale (FSS—9) with modern psychometric methods is warranted. Objective: To determine the psychometric properties of the FSS—9 in multiple sclerosis (MS): internal scale validity; person response validity; unidimensionality; uniform differential item functioning; temporal stability of response patterns; and ability to separate people into distinct groups of fatigue. Methods: Rasch analyses were conducted on data from a Norwegian and a Swedish MS cohort followed for two years. Results: Item estimations in the FSS—9 did not differ between sex or levels of education but between the cohorts with regard to disability, disease course and time for evaluation, however, items 1 and 2 demonstrated unacceptable high outfit mean-square values in both cohorts. In an FSS—7 item version, items 3 and 4 in the Norwegian and 4 in the Swedish cohort demonstrated unacceptable goodness of fit but high separation indexes. In the FSS—7, the first unidimensional factor explained 87.5% (Norwegian cohort) and 86.4% (Swedish cohort) of the total variation. Conclusions: In MS, the FSS—7 demonstrates better psychometric properties than the FSS—9; items 1 and 2 neither empirically nor conceptually fit with the other seven items.

Fatigue Severity

As one of the most frequent symptoms, measurement of fatigue is an issue of interest in Parkinson’s disease (PD). The fatigue severity scale (FSS) is one of the recommended questionnaires for this purpose. The aim of our study was to evaluate psychometric properties of the Persian version of the FSS (FSS-Per) to assess fatigue in PD patients. Ninety nondemented idiopathic Parkinson’s disease (IPD) patients were consecutively recruited from an outpatient referral movement disorder clinic. In addition to the disease severity scales, the FSS-Per was used for fatigue measurement. The internal consistency coefficient was larger than 0.8 for all of the items with a total Cronbach’s alpha of 0.96 (95% CI: 0.95–0.97). The FSS-Per score correlated with the UPDRS score (, ) and the “Hoehn and Yahr” (HY) stage (, ). The total score of the FSS-Per significantly discriminated IPD patients with more severe disability (HY stage > 2) versus those with less severe disease (HY stage ) (AUC = 0.81 (95% CI: 0.72–0.90)). The FSS-Per fulfilled a high internal consistency and construct validity to measure the severity of fatigue in Iranian IPD patients. These acceptable psychometric properties were reproducible in subgroups of IPD patients regarding different levels of education, disease severity, sex and age groups.
