There was an overall absence of item order distortion between response categories. The Rasch model's expected category response values were compatible with item weights previously assigned. <jats:italic>Conclusions<\/jats:italic>: Our analysis suggests that: (1) the score can be summated to estimate an overall disease severity score; (2) the response options of the 10 items are not significantly distorted; and (3) the assigned weights of the response options are appropriate.
