The FIQR should be considered as an instrument consisting of three separate subscales representing 'function', 'overall impact', and 'symptoms'. We recommend calculating and reporting on both a 0-10 and a 0-4 category scale. Also, if using the total FIQR score as an outcome measure, this should be done with caution, until revision of the rating scale.
