Scoring the FIQR and SIQR
 

The FIQR is much easier to score compared to its predecessor – the FIQ.

The SIQR has exactly the same scoring algorithm as the FIQR

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)
 

 Missing answers

You will need to compensate for unanswered questions. In such cases we recommend the use of the following “weighting” factor:
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).
Consider the the questionnaire invalid if: 2 or more items are missed from the functional domain or any item is missed from the overall domain or the symptom domain.
