SCORING THE FIQR
There are just 3 steps:
Step 1. Sum the scores for each of the three domains (function, overall, and
Step 2. Divide domain 1 score by three, divide domain 2 score by one (that is, it
is unchanged), and divide domain score 3 by two.
Step 3. Add the three resulting domain scores to obtain the total Revised
Fibromyalgia Impact Questionnaire (FIQR) score.
If you are not using computerized input which demands the completion of each question
before the next in line can be tackled (e.g. a paper questionnaire), you will need to
compensate for unanswered questions. In such cases we recommend the use of the following
If only x questions from the first section (function) were answered, one would weigh the
summated score of the x questions by 9/x (as there are 9 items in the function set of
questions) Likewise the second section (overall impact) would have a weighting of 2/x
(there are only 2 items) and the third section (symptoms) would have a weighting of 10/x
(there are 10 items).
Sometimes one or two items of the first domain (i.e. function), cannot be answered because
a subject has not performed that activity within the past 7 days or is physically unable
to perform that activity. We therefore recommend using the following amendment of the
sentinel question for the first domain:
"Check the box that best indicates how much your fibromyalgia made it difficult to perform
each of the following 9 activities during the past 7 days. If you did not perform a
particular activity in the last 7 days, rate the difficulty for the last time you
performed the activity. If you can't perform an activity, check the last box".
