Development of a screening tool to identify patients with axial spondyloarthritis: a cognitive interview study.

It is feasible to design a screening tool that is accessible to most (e.g., reading level) and clear to individuals with back pain. An evidence-based approach to demonstrate the validity of the screening tool will be critical for it to be implemented widely into clinical practice. Key Points • Our study developed two sample screeners that are clear to individuals with back pain and accessible to most with an overall Flesch-Kincaid reading grade of 7.5 and Flesch reading ease of 65.7%. • Questions that were considered irrelevant to participants were eliminated such as responsiveness of pain to nonsteroidal anti-inflammatory drug (NSAID). • It is feasible to design a screening tool that is accessible to most (e.g., reading level) and clear to individuals with back pain.
