The Revised Fibromyalgia Impact Questionnaire (FIQR) has previously proved to be a valuable tool in both clinical and research settings. The study objective was to translate and validate the FIQR in Danish.Patients and Methods: A forward/backward translation, following the WHO-guidelines, was used to develop the Danish version of FIQR. The Danish translation of FIQR was answered by 101 patients suffering from fibromyalgia. The patients simultaneously answered the Hospital Anxiety and Depression Scale (HADS) and the 36-Item Short-Form Health Survey (SF-36) for validation.Results: The Danish FIQR showed excellent internal consistency, and reliability with Interclass Correlation Coefficients above 0.9. The correlations to HADS and SF-36 ranged from fair to very good. All results were found to have a p-value < 0.05.Conclusion: The present version of the Danish FIQR presents a valid and reliable tool for monitoring the impact of fibromyalgia.Keywords: fibromyalgia, questionnaire, chronic pain, evaluation, validation, translation
