Each item of the POSAS is rated on a 10-point score. The lowest score is ‘1’, which corresponds to the situation of normal skin (i.e. normal pigmentation, no itching). Score 10 equals the largest difference from normal skin (i.e. the worst imaginable scar or sensation).
The total score of both scales can be simply calculated by summing up the scores of each of the six items. The total score can range from 6 to 60. The overall opinion item is not included in the sum score.
