Abstract		Objective: To evaluate the psychometric properties of the Modiffied Fatigue Impact Smle (MFIS) in lour different European countries. Methods: Individuals with definite multiple sclerosis (MS) were selected from centres in laly (n =50), Spain (n =30), Slovenia (n =50) and Belgium (n =51) and completed the MFIS and the Fatigue Severity Scale (FSS) twice (interval <3 days). Results: In all four samples, the MFIS demonstrated a good reproducibility (intnclass correlation coefficient _>0.84), with no significant differences between countries (P =0.77). Moderate correlacions were found between the MFIS and FSS. No signifimnt carrelations were found between the MFIS and age, gender, type of MS, duration of the disease or EDSS score. Factor analysis of all samples (n =181) could not completely confirm the original assumptions concerning the physical, cognitive and psychosocial component The toal score, the physical and the cognitive subscale of the scale were homogeneous (Cron6ach's alpha 0.92, 0.88 and 0.92, respectively), but the prychosocal su6sde had a Cronbach:s alpha of 0,65. Conclusions: No cuhunl or linguistic differences were found in the psychometric properties of the Belgian, Italian, Slovenian or Spanish version of the MFIS. We recommend this smle for research purposes and in clinid practice Due to the limited value of the psychosocial subscale, we recommend interpreting this substale with mudon.
