Validation of the Czech version of the questionnaire evaluating the early detection of intestinal and extraintestinal manifestations in patients with axial spondyloarthritis at risk of developing idiopathic intestinal inflammation: IBD screening criteria for patients with SpA
Abstract
Questionnaires are a simple psychometric tool to assess the subjective ailments of patients with chronic rheumatic diseases. Concerning the latě diagnosis ofinflammatory bowel disease (IBD) in patients with spondyloarthritis (SpA), a questionnaire was created in theform of screening criteria evaluating intestinal and extraintestinal problems over time.
The aim ofthis worh was the Czech translation and its linguistic validation, which consisted ofseveral phases. In the prst phase, an independent translation ofthe originál Engtish version into the Czech language was performed, and these versions were analyzed and discussed by the author group through a process ofconsensus synthesis.
In the second phase, the back translation ofthe unified Czech version ofthe questionnaire was carried out. In this way, a pre-fmal version ofthe questionnaire was created, which was compteted by a total of 68 patients suffering from axial SpA, of which 39 patients with non-radiographic axial SpA (nr-AxSpA) and 29 patients with anhylosing spondylitis (AS).
A separate part consisted of a feedbach questionnaire to evaluate the content, linguistic and stylistic aspects. The comments raised were included in the finál Czech version ofthe questionnaire.
In this worh, we present the Czech version ofthe IBD Screening Questionnaire intended for patients with SpA. An official translation will thus enable its common use in both ctinical and research fields.
