Introduction: The Composite Autonomic Symptom Score (COMPASS 31) is a validated self-assessment questionnaire quantifying the severity and distribution of autonomic symptoms across six domains (orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder and pupillomotor functions) by scoring 31 clinically selected questions. The aim of this study was to translate into Danish and validate the Danish version of COMPASS 31.
Methods: The original (US) English version of the COMPASS 31 questionnaire was translated into Danish via forward/backward translation and validated in accordance with a protocol set forth by the Autonomic Group at the Mayo Clinic.
