Is the widely-used score in axial spondyloarthritis, Bath Ankylosing Spondylitis Disease Activity Index, influenced by patients’ optimism? A cross-sectional study of 206 patients
Résumé
The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) [1] is widely used to assess disease activity in axial spondyloarthritis (axSpA) and initiate tumor necrosis factor α-inhibitor therapy [2]. Because BASDAI is a patient-reported outcome, and therefore subject to variability, there may be questions regarding the link between BASDAI results and pathogenesis of axSpA. Specifically, BASDAI score is partly explained by psychological distress (i.e., anxiety/depression) [3], which may be an issue when using it to decide on treatment strategies.
