The different POSAS 3.0 questionnaires:
- POSAS 3.0 patient scale
- POSAS 3.0 observer scale
The generic scar version can be used for all types of scars, except for ‘linear’ scars that have a linear shape and are often the result of a (surgical) incision. The linear scar version of the POSAS 3.0 can be used for those scars.
Each item of the POSAS 3.0 is rated on a 5-point score. The lowest score is ‘1’, which corresponds to the situation of normal skin (i.e. normal pigmentation, no itching). Score 5 equals the largest difference from normal skin (i.e. the worst imaginable scar or sensation).
