The COMPASS 31 is a questionnaire used to assess autonomic symptoms. The research aimed to ensure the translated version accurately reflects the original questionnaire's meaning and is consistently understood by the target population. The successful linguistic validation and demonstrated reliability of the Brazilian Portuguese COMPASS 31 are significant for clinicians working with this population.
