Materials & Methods: In this cross-sectional methodological study, the psychometric properties of the Persian version of the FIS (FIS-P) were examined. The participants were 280 Iranian people (140 healthy adults; 140 stroke patients) who were assessed using the FIS-P, fatigue severity scale (FSS), and SF-36 questionnaire. The content, convergent, and discriminant validity of the FIS-P were evaluated using CVR and CVI, Pearson correlation, and independent-sampling T-tests, respectively. Furthermore, interrater reliability and test-retest reliability were assessed via the intra-class correlation coefficient and SEM. The internal consistency reliability was evaluated using Cronbach’s α.
