Using a ruler, the score is determined by measuring the distance (mm) on the 10-cm line between the "no discomfort"/"no pain" anchor and the patient's mark, providing a range of scores from 0-100.

The following cut points on the pain VAS have been recommended: no pain (0-4 mm), mild pain(5-44 mm), moderate pain (45-74 mm), and severe pain (75-100 mm).

There are 20 questions in the CIVIQ-20, each with 5 possible answers (1 to 5), the minimum possible score being 20 and the maximum 100. In order to calculate the GIS, the difference between the final score and the minimum possible score is to be divided by the difference between the theoretical maximum and minimum scores (100-20=80), multiplied by 100.
