Translation and cross-cultural adaptation of the Identification of Spondyloarthritis Questionnaire (IBIS-Q) into Danish for patients with inflammatory bowel disease

Following an international, standardised guideline, the IBIS-Q was successfully translated and cross-culturally adapted into Danish, and face validity was confirmed. The IBIS-Q is the first available questionnaire to assess Danish patients with IBD for SpA symptoms. Psychometric validation of the measurement properties of IBIS-Q is recommended prior to implementation.
