title: [Multiple sclerosis: cross-cultural adaptation and validation of the modified fatigue impact scale].
abstract: OBJECTIVE
  The aim of this study is a cross-cultural adaptation and validation of the modified fatigue impact scale for Portuguese (MFIS-BR).
  
  
  METHODS
  The MFIS was translated to Portuguese and re-translated to English. Two pilot studies had been carried through to obtain the MFIS-BR, which was applied to 57 consecutive stable MS patients and 45 healthy controls. The retest was applied 30 days later.
  
  
  RESULTS
  In analyzing the statistics the internal consistency reability was similar to the original scale (0.74-0.86). The MFIS-BR showed ability to identify the different groups. Concerning the reliability the interclass correlation coefficient showed an excellent agreement (0.264-1.0).
  
  
  CONCLUSIONS
  The MFIS-BR fills the criteria of applicability, sensibility which are similar to the original version.
