Validation and reliability of the Turkish version of the composite autonomic symptom score 31

This study aimed to validate a Turkish version of the Composite Autonomic Symptom Score 31 (T-COMPASS 31) for assessing autonomic dysfunction.

The COMPASS 31 questionnaire was translated into Turkish following a rigorous protocol. Forty-five patients with autonomic dysfunction symptoms related to their primary disease and 45 healthy controls matched for age and sex participated in the study. All participants completed the T-COMPASS 31 twice, with a six-week interval between administrations.

The T-COMPASS 31 demonstrated strong test-retest reliability, with scores remaining consistent upon retesting. Internal consistency analysis yielded high scores, indicating the questionnaire's effectiveness in accurately measuring autonomic dysfunction. Patients with autonomic dysfunction had significantly higher T-COMPASS 31 scores compared to healthy controls, thus supporting the validity of the T-COMPASS 31 as a tool for detecting this condition.

This study successfully validated the T-COMPASS 31, establishing it as a reliable and accurate method for assessing autonomic dysfunction in Turkish-speaking populations.
