REVISED FIBROMYALGIA IMPACT QUESTIONNAIRE (FIQR)

The Fibromyalgia Impact Questionnaire (FIQ) is a commonly used instrument in the evaluation of fibromyalgia (FM) patients. Over the last 18 years, since the publication of the original FIQ, several deficiencies have become apparent, and the cumbersome scoring algorithm has been a barrier to widespread clinical use. The FIQR was developed in response to known deficiencies of the FIQ with the help of a patient focus group. The FIQR has the same 3 domains as the FIQ (that is, function, overall impact, and symptoms). It differs from the FIQ in having modified function questions and the inclusion of questions on memory, tenderness, balance, and environmental sensitivity. All questions are graded on a 0—10 numeric scale. The FIQR has sound psychometric properties, discriminates between Fibromyalgia patients and patients with RA, SLE, and Major depressive disease (MDD), takes just over 1 minute to complete, is easy to score, and can be used in online surveys.
