The Fibromyalgia Impact Questionnaire (FIQ) was developed in the late 1980s and was first published in 1991. It has subsequently become one of the most frequently used tools in the evaluation of fibromyalgia (FM) patients. However, issues in regard to some aspects of its content and rather cumbersome scoring algorithm have become apparent. With these issues in mind, a revised version of the questionnaire was developed: the Revised Fibromyalgia Impact Questionnaire (FIQR), which attempts to address the limitations of the FIQ while retaining the essential properties of the original instrument. The FIQR was developed to include relevant questions that were not part of the original FIQ and to improve the scoring algorithm.

The FIQR has 21 questions, divided into three sets of domains: function, overall impact, and symptoms. The total score is the sum of the three domain scores, with the weighting of the domains changed from the FIQ. The total maximal score of the FIQR is 100.

There are just 3 steps in scoring:

Step 1.     Sum the scores for each of the three domains (function, overall, and symptoms).

Step 2.     a. Divide  function domain sum (0-90) by 3 (upper limit 30)
                  b. Divide overall impact domain  sum (0-20) by one (0-20)  (that is, it is unchanged)
                  c. Divide symptom domain sum (0-100) by 2 (upper limit 50)                                     

Step 3.     Add the three resulting domain scores (a, b and c) to obtain the total score of  
                  the FIQR or SIQR (range 0 -100).

The Original FIQ was subdivided into 3 domains; the "functional" domain, the "overall" domain and the "symptom" domain; these 3 domains have been retained in the FIQR. However, since the publication of the FIQ in 1991, several issues regarding ethocultural usage, symptom relevance and arcane scoring became apparent. These issues have been addressed in the FIQR.

1. The original functional domain was originally devised with middle class Caucasian women in mind (as this was the predominant group seen in the OHSU clinic). Therefore, with the help of a patient focus group, a completely new and more generic set of 9 questionswere developed for the functional domain of the FIQR:

1. Brush or comb your hair
2. Walk continuously for 20 minutes 
3. Prepare a homemade meal 
4. Vacuum, scrub or sweep floors 
5. Lift and carry a bag full of groceries 
6. Climb one flight of stairs 
7. Change bed sheets 
8. Sit in a chair for 45 minutes 
9. Go shopping for groceries

2. The original overall domain asked a question regarding whether patients could work, including housework. This introduced a an interpretation dilemma, as it assumed that doing housework involved the same time constraints and effort as holding down a full time job. Therefore, the 2 overall domain questions were phrased in terms as to the extent that fibromyalgia interfered with the patient's goals for the week and the extent that the patient felt overwhelmed by their fibromyalgia symptoms:

1. Fibromyalgia prevented me from accomplishing goals for the week
2. I was completely overwhelmed by my fibromyalgia symptoms

3. The original symptom domain did not contain some feature of fibromyalgia that became recognized as clinically relevant after its introduction in 1991. Therefore the FIQR was modified by adding 4 new questions to take into account the contemporary clinical spectrum of fibromyalgia. These additional questions are related to memory, balance, tenderness and environmental sensitivity. here are the 10 symptom
