Abstract

This comparative observational study aimed to validate an online Patient-oriented Psoriasis Area and Severity Index (PO-PASI) by comparing it against the Psoriasis Area and Severity Index (PASI), of 97 adult participants with chronic plaque psoriasis. Pearson's correlation coefficient of 0.866 (P-value = 0.0001) showed a strong positive linear correlation, and interclass correlation coefficients [ICC scores = 0.864 [95% confidence intervals (CIs) (0.803 < ICC < 0.907)]] suggest an interrater reliability of 'good' to 'excellent' when comparing PO-PASI to the PASI score. Additionally, we compared PO-PASI and PASI with DLQI and demonstrated an overall stronger positive correlation between PO-PASI and DLQI when compared to PASI.
