Validation of the Danish translation of the atrial fibrillation severity scale: a study on linguistic and cultural adaptation

Atrial fibrillation (AF) stands as the most common cardiac arrhythmia on a global scale with a substantial symptom burden impacting the quality of life (QoL) of patients with AF. Consequently, assessing and monitoring symptoms in patients with AF has gained increased interest, leading to a rise in patient-reported outcome measures (PROMs). PROMs provide valuable insights into the patient’s perspective, allowing for a more patient-centric approach to care. One of these PROMs is the Atrial Fibrillation Severity Scale (AFSS), a convenient and straightforward instrument for assessing symptom severity in patients with AF, potentially enabling healthcare professionals to tailor interventions accordingly. However, no Danish version of AFSS exists. This study aims to translate and linguistically validate the AFSS in accordance with MAPI Research Trust Guidelines.
