The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI) and the Dougados Functional Index (DFI) are the most commonly used instruments to measure disease activity and functioning in ankylosing spondylitis (AS). The aim of this study was to translate, adapt and validate these instruments into the Spanish language. ⋯ The Mexican Spanish versions of the BASDAI, BASFI, and DFI showed adequate reliability, validity and responsiveness to clinical change. These instruments can be used in the clinical evaluation of Spanish-speaking patients with AS.
