Clinimetric properties of a translated and culturally adapted Norwegian version of the Patient and Observer Scar Assessment Scale for use in clinical practice and research

To translate and culturally adapt the Patient Observer Scar Assessment Scale, POSAS, to Norwegian explore its test-retest, intra- inter-tester reliability. POSAS was translated into following international guidelines in collaboration with an translation bureau. Twenty-six adults 24 children were recruited from a burns outpatient clinic.

A version (POSAS-NV) developed. Inter-tester ICC parameters varied between 0.203 0.728, total sum score, = 0.528 (0.280–0.708). Intra-tester ranged 0.575 0.858. demonstrated high test–retest reliability POSAS-NV found satisfactory, but not scale.
