Translation and Validation of the Self-Assessment Psoriasis Area Severity Index.

ABSTRACT:

Background

The self-assessment psoriasis area severity index (SAPASI) is a patient-administered psoriasis assessment tool for which we present a validated translation from English to Swedish.

Methods

Validity was evaluated in this single-centre study using the psoriasis area severity index (PASI) as the standard. Test-retest reliability was assessed using repeated SAPASI measurements.

Results

Significant correlations (p < 0.0001) using Spearman's correlation coefficient (r) were found between PASI and SAPASI scores (r = 0.60) for 51 participants (median baseline PASI 4.4, interquartile range [IQR]: 1.8-5.6) and repeated SAPASI measurements (r = 0.70) among 38 participants (median baseline SAPASI 4.0, IQR: 2.5-6.1). Bland-Altman plots showed generally higher SAPASI
